Abciximab binds to the glycoprotein (GP) IIb/IIIa receptor of human platelets and inhibits platelet aggregation by preventing the binding of fibrinogen, von Willebrand factor, and other adhesive molecules. It also binds to vitronectin (αvβ3) receptor found on platelets and vessel wall endothelial and smooth muscle cells.Abciximab is indicated as an adjunct to percutaneous coronary intervention for the prevention of cardiac ischemic complications in patients undergoing percutaneous coronary intervention and in patients with unstable angina not responding to conventional medical therapy when percutaneous coronary intervention is planned within 24 hours. Abciximab is intended for use with aspirin and heparin and has been studied only in that setting.Abciximab inhibits platelet aggregation by preventing the binding of fibrinogen, von Willebrand factor, and other adhesive molecules to GPIIb/IIIa receptor sites on activated platelets. A single intravenous bolus dose from 0.15 mg/kg to 0.30 mg/kg produced rapid dose-dependent inhibition of platelet function. After two hours post-injection with a dose of 0.25 - 0.30 mg/kg, 80% of the GPIIb/IIIa receptors were blocked and platelet aggregation was prevented. GPIIb/IIIa is the major surface receptor involved in the final pathway of platelet aggregation. Bleeding time increases to over 30 minutes at the aforementioned doses. To compare, baseline values were five minutes.Abciximab binds to the intact platelet GPIIb/IIIa receptor, which is a member of the integrin family of adhesion receptors and the major platelet surface receptor involved in platelet aggregation. This binding is thought to involve steric hindrance and/orconformational alterations which block access of large molecules to the receptor rather than direct interaction with the RGD (arginine-glycine-aspartic acid) binding site of GPIIb/IIIa. By binding to the vitronectin receptor (also known as the αvβ3 integrin), abciximab blocks effects mediated by this integrin which include cell adhesion.

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].Amino Acids, Peptides, and

KgMedice Arzneimittel Pütter Gmb H Co. KgIntravenous; Subcutaneous1000 IU/0.5mlNAThe most common side effects with Abseamed (which may affect more than 1 in 10 people) are nausea (feeling sick), diarrhoea, vomiting, fever and headache. Flu-like illness may occur especially at the start of treatment. Abseamed contains the active substance epoetin alfa and is a ‘biosimilar medicine’. This means that Abseamed is highly similar to another biological medicine (the ‘reference medicine’) that is already authorised in the EU. The reference medicine for Abseamed is Eprex/Erypo.to treat anaemia (low red blood cell counts) that is causing symptoms in patients with chronic kidney failure (long-term, progressive decrease in the ability of the kidneys to work properly) or other kidney problems; to treat anaemia in adults receiving chemotherapy for certain types of cancer and to reduce the need for blood transfusions; to increase the amount of blood that can be taken in adult patients with moderate anaemia and normal blood iron levels who are going to have an operation and donate their own blood before surgery (autologous blood transfusion); to reduce the need for blood transfusions in adults with moderate anaemia who are about to undergo major orthopaedic (bone) surgery, such as hip surgery. It is used in patients with normal blood iron levels who could experience complications from a blood transfusion, if they do not donate their own blood before surgery and are expected to lose 900 to 1,800 ml of blood; to treat anaemia in adults with myelodysplastic syndromes (conditions in which the production of healthy blood cells is defective). Abseamed is used when patients are at low or intermediate risk of developing acute myeloid leukaemia and have low levels of the natural hormone erythropoietin.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].Antianemic PreparationsNANANANAErythropoietin receptorAbseamedMedice Arzneimittel Pütter Gmb H Co.

Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].Blood and Blood Forming OrgansNANANANAErythropoietin receptorAbseamedMedice Arzneimittel Pütter Gmb H Co.

Flu-like illness may occur especially at the start of treatment. Abseamed contains the active substance epoetin alfa and is a ‘biosimilar medicine’. This means that Abseamed is highly similar to another biological medicine (the ‘reference medicine’) that is already authorised in the EU. The reference medicine for Abseamed is Eprex/Erypo.to treat anaemia (low red blood cell counts) that is causing symptoms in patients with chronic kidney failure (long-term, progressive decrease in the ability of the kidneys to work properly) or other kidney problems; to treat anaemia in adults receiving chemotherapy for certain types of cancer and to reduce the need for blood transfusions; to increase the amount of blood that can be taken in adult patients with moderate anaemia and normal blood iron levels who are going to have an operation and donate their own blood before surgery (autologous blood transfusion); to reduce the need for blood transfusions in adults with moderate anaemia who are about to undergo major orthopaedic (bone) surgery, such as hip surgery. It is used in patients with normal blood iron levels who could experience complications from a blood transfusion, if they do not donate their own blood before surgery and are expected to lose 900 to 1,800 ml of blood; to treat anaemia in adults with myelodysplastic syndromes (conditions in which the production of healthy blood cells is defective). Abseamed is used when patients are at low or intermediate risk of developing acute myeloid leukaemia and have low levels of the natural hormone erythropoietin.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079].

Flu-like illness may occur especially at the start of treatment. Abseamed contains the active substance epoetin alfa and is a ‘biosimilar medicine’. This means that Abseamed is highly similar to another biological medicine (the ‘reference medicine’) that is already authorised in the EU. The reference medicine for Abseamed is Eprex/Erypo.to treat anaemia (low red blood cell counts) that is causing symptoms in patients with chronic kidney failure (long-term, progressive decrease in the ability of the kidneys to work properly) or other kidney problems; to treat anaemia in adults receiving chemotherapy for certain types of cancer and to reduce the need for blood transfusions; to increase the amount of blood that can be taken in adult patients with moderate anaemia and normal blood iron levels who are going to have an operation and donate their own blood before surgery (autologous blood transfusion); to reduce the need for blood transfusions in adults with moderate anaemia who are about to undergo major orthopaedic (bone) surgery, such as hip surgery. It is used in patients with normal blood iron levels who could experience complications from a blood transfusion, if they do not donate their own blood before surgery and are expected to lose 900 to 1,800 ml of blood; to treat anaemia in adults with myelodysplastic syndromes (conditions in which the production of healthy blood cells is defective). Abseamed is used when patients are at low or intermediate risk of developing acute myeloid leukaemia and have low levels of the natural hormone erythropoietin.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing.

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].GlycoproteinsNANANANAErythropoietin receptorAbseamedMedice Arzneimittel Pütter Gmb H Co.

It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].Hematopoietic Cell Growth FactorsNANANANAErythropoietin receptorAbseamedMedice Arzneimittel Pütter Gmb H Co.

The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].PeptidesNANANANAErythropoietin receptorBinocritSandozSandozIntravenous; Subcutaneous3000 IU/0.3mlNAThe most common side effects with Binocrit (which may affect more than 1 in 10 people) are nausea (feeling sick),diarrhoea, vomiting, fever and headache. Flu-like illness may occur especially at the start of treatment. Binocrit contains the active substance epoetin alfa and is a ‘biosimilar medicine’. This means that Binocrit is highly similar to another biological medicine (the ‘reference medicine’) that is already authorised in the EU. The reference medicine for Binocrit is Eprex/Erypo.to treat anaemia (low red blood cell counts) that is causing symptoms in patients with ‘chronic kidney failure’ (long-term, progressive decrease in the ability of the kidneys to work properly) or other kidney problems; to treat anaemia in adults receiving chemotherapy for certain types of cancer and to reduce the need for blood transfusions; to increase the amount of blood that can be taken in adult patients with moderate anaemia and normal blood iron levels who are going to have an operation and donate their own blood before surgery (autologous blood transfusion); to reduce the need for blood transfusions in adults with moderate anaemia who are about to undergo major orthopaedic (bone) surgery, such as hip surgery. It is used in patients with normal blood iron levels who could experience complications from a blood transfusion, if they do not donate their own blood before surgery and are expected to lose 900 to 1,800 ml of blood; to treat anaemia in adults with myelodysplastic syndromes (conditions in which the production of healthy blood cells is defective). Binocrit is used when patients are at low or intermediate risk of developing acute myeloid leukaemia and have low levels of the natural hormone erythropoietin.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080].

The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorBinocritSandozSandozIntravenous; Subcutaneous6000 IU/0.6mlNAThe most common side effects with Binocrit (which may affect more than 1 in 10 people) are nausea (feeling sick),diarrhoea, vomiting, fever and headache. Flu-like illness may occur especially at the start of treatment. Binocrit contains the active substance epoetin alfa and is a ‘biosimilar medicine’. This means that Binocrit is highly similar to another biological medicine (the ‘reference medicine’) that is already authorised in the EU. The reference medicine for Binocrit is Eprex/Erypo.to treat anaemia (low red blood cell counts) that is causing symptoms in patients with ‘chronic kidney failure’ (long-term, progressive decrease in the ability of the kidneys to work properly) or other kidney problems; to treat anaemia in adults receiving chemotherapy for certain types of cancer and to reduce the need for blood transfusions; to increase the amount of blood that can be taken in adult patients with moderate anaemia and normal blood iron levels who are going to have an operation and donate their own blood before surgery (autologous blood transfusion); to reduce the need for blood transfusions in adults with moderate anaemia who are about to undergo major orthopaedic (bone) surgery, such as hip surgery. It is used in patients with normal blood iron levels who could experience complications from a blood transfusion, if they do not donate their own blood before surgery and are expected to lose 900 to 1,800 ml of blood; to treat anaemia in adults with myelodysplastic syndromes (conditions in which the production of healthy blood cells is defective). Binocrit is used when patients are at low or intermediate risk of developing acute myeloid leukaemia and have low levels of the natural hormone erythropoietin.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing.

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorBinocritSandozSandozIntravenous; Subcutaneous9000 IU/0.9mlNAThe most common side effects with Binocrit (which may affect more than 1 in 10 people) are nausea (feeling sick),diarrhoea, vomiting, fever and headache.

Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorBinocritSandozSandozIntravenous; Subcutaneous40000 IU/1mlNAThe most common side effects with Binocrit (which may affect more than 1 in 10 people) are nausea (feeling sick),diarrhoea, vomiting, fever and headache. Flu-like illness may occur especially at the start of treatment. Binocrit contains the active substance epoetin alfa and is a ‘biosimilar medicine’. This means that Binocrit is highly similar to another biological medicine (the ‘reference medicine’) that is already authorised in the EU. The reference medicine for Binocrit is Eprex/Erypo.to treat anaemia (low red blood cell counts) that is causing symptoms in patients with ‘chronic kidney failure’ (long-term, progressive decrease in the ability of the kidneys to work properly) or other kidney problems; to treat anaemia in adults receiving chemotherapy for certain types of cancer and to reduce the need for blood transfusions; to increase the amount of blood that can be taken in adult patients with moderate anaemia and normal blood iron levels who are going to have an operation and donate their own blood before surgery (autologous blood transfusion); to reduce the need for blood transfusions in adults with moderate anaemia who are about to undergo major orthopaedic (bone) surgery, such as hip surgery. It is used in patients with normal blood iron levels who could experience complications from a blood transfusion, if they do not donate their own blood before surgery and are expected to lose 900 to 1,800 ml of blood; to treat anaemia in adults with myelodysplastic syndromes (conditions in which the production of healthy blood cells is defective). Binocrit is used when patients are at low or intermediate risk of developing acute myeloid leukaemia and have low levels of the natural hormone erythropoietin.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced.

Erythropoietin is produced by the kidneys. In patients receiving chemotherapy or with kidney problems, anaemia can be caused by a lack of erythropoietin, or by the body not responding enough to the erythropoietin it has naturally. The epoetin theta in Biopoin works in the body in the same way as the natural hormone to stimulate red blood cell production. It is produced by a method known as ‘recombinant DNA technology’: it is made by a cell that has received a gene (DNA), which makes it able to produce epoetin theta.Biopoin is used to treat anaemia (low levels of red blood cells or haemoglobin) that is causing symptoms. It is used in adults with chronic renal failure (long-term, progressive decrease in the ability of the kidneys to work properly) and in adults with non-myeloid cancer (cancer not originating in the bone marrow) who are receiving chemotherapy (medicines to treat cancer).potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorBiopoinTevaTevaIntravenous; Subcutaneous2000 IU/0.5mlNAThe most common side effects with Biopoin (seen in between 1 and 10 patients in 100) are shunt thrombosis (clots that can form in blood vessels of patients on dialysis, a blood clearance technique), headache, hypertension (high blood pressure), hypertensive crisis (sudden, dangerously high blood pressure), skin reactions, arthralgia (joint pain) and influenza (flu)-like illness.The active substance in Biopoin, epoetin theta, is a copy of a human hormone called erythropoietin that stimulates the production of red blood cells from the bone marrow. Erythropoietin is produced by the kidneys. In patients receiving chemotherapy or with kidney problems, anaemia can be caused by a lack of erythropoietin, or by the body not responding enough to the erythropoietin it has naturally. The epoetin theta in Biopoin works in the body in the same way as the natural hormone to stimulate red blood cell production. It is produced by a method known as ‘recombinant DNA technology’: it is made by a cell that has received a gene (DNA), which makes it able to produce epoetin theta.Biopoin is used to treat anaemia (low levels of red blood cells or haemoglobin) that is causing symptoms. It is used in adults with chronic renal failure (long-term, progressive decrease in the ability of the kidneys to work properly) and in adults with non-myeloid cancer (cancer not originating in the bone marrow) who are receiving chemotherapy (medicines to treat cancer).potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days).

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorBiopoinTevaTevaIntravenous; Subcutaneous10000 IU/1.0mlNAThe most common side effects with Biopoin (seen in between 1 and 10 patients in 100) are shunt thrombosis (clots that can form in blood vessels of patients on dialysis, a blood clearance technique), headache, hypertension (high blood pressure), hypertensive crisis (sudden, dangerously high blood pressure), skin reactions, arthralgia (joint pain) and influenza (flu)-like illness.The active substance in Biopoin, epoetin theta, is a copy of a human hormone called erythropoietin that stimulates the production of red blood cells from the bone marrow. Erythropoietin is produced by the kidneys.

Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorEpoetin Alfa HexalHexal AgHexal AgIntravenous; Subcutaneous1000 IU/0.5mlNAThe most common side effects with Epoetin Alfa Hexal (which may affect more than 1 in 10 people) are nausea (feeling sick), diarrhoea, vomiting, fever and headache. Flu-like illness may occur especially at the start of treatment.Epoetin Alfa Hexal contains the active substance epoetin alfa and is a ‘biosimilar medicine’. This means that Epoetin Alfa Hexal is highly similar to another biological medicine (the ‘reference medicine’) that is already authorised in the EU. The reference medicine for Epoetin Alfa Hexal is Eprex/Erypo.to treat anaemia (low red blood cell counts) that is causing symptoms in patients with ‘chronic kidney failure’ (long-term, progressive decrease in the ability of the kidneys to work properly) or other kidney problems; to treat anaemia in adults receiving chemotherapy for certain types of cancer and to reduce the need for blood transfusions; to increase the amount of blood that can be taken in adult patients with moderate anaemia and normal blood iron levels who are going to have an operation and donate their own blood before surgery (autologous blood transfusion); to reduce the need for blood transfusions in adults with moderate anaemia who are about to undergo major orthopaedic (bone) surgery, such as hip surgery. It is used in patients with normal blood iron levels who could experience complications from a blood transfusion, if they do not donate their own blood before surgery and are expected to lose 900 to 1,800 ml of blood; to treat anaemia in adults with myelodysplastic syndromes (conditions in which the production of healthy blood cells is defective). Epoetin Alfa Hexal is used when patients are at low or intermediate risk of developing acute myeloid leukaemia and have low levels of the natural hormone erythropoietin.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784].

In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorEpoetin Alfa HexalHexal AgHexal AgIntravenous; Subcutaneous4000 IU/0.4mlNAThe most common side effects with Epoetin Alfa Hexal (which may affect more than 1 in 10 people) are nausea (feeling sick), diarrhoea, vomiting, fever and headache. Flu-like illness may occur especially at the start of treatment.Epoetin Alfa Hexal contains the active substance epoetin alfa and is a ‘biosimilar medicine’. This means that Epoetin Alfa Hexal is highly similar to another biological medicine (the ‘reference medicine’) that is already authorised in the EU. The reference medicine for Epoetin Alfa Hexal is Eprex/Erypo.to treat anaemia (low red blood cell counts) that is causing symptoms in patients with ‘chronic kidney failure’ (long-term, progressive decrease in the ability of the kidneys to work properly) or other kidney problems; to treat anaemia in adults receiving chemotherapy for certain types of cancer and to reduce the need for blood transfusions; to increase the amount of blood that can be taken in adult patients with moderate anaemia and normal blood iron levels who are going to have an operation and donate their own blood before surgery (autologous blood transfusion); to reduce the need for blood transfusions in adults with moderate anaemia who are about to undergo major orthopaedic (bone) surgery, such as hip surgery. It is used in patients with normal blood iron levels who could experience complications from a blood transfusion, if they do not donate their own blood before surgery and are expected to lose 900 to 1,800 ml of blood; to treat anaemia in adults with myelodysplastic syndromes (conditions in which the production of healthy blood cells is defective). Epoetin Alfa Hexal is used when patients are at low or intermediate risk of developing acute myeloid leukaemia and have low levels of the natural hormone erythropoietin.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days).

The reference medicine for Epoetin Alfa Hexal is Eprex/Erypo.to treat anaemia (low red blood cell counts) that is causing symptoms in patients with ‘chronic kidney failure’ (long-term, progressive decrease in the ability of the kidneys to work properly) or other kidney problems; to treat anaemia in adults receiving chemotherapy for certain types of cancer and to reduce the need for blood transfusions; to increase the amount of blood that can be taken in adult patients with moderate anaemia and normal blood iron levels who are going to have an operation and donate their own blood before surgery (autologous blood transfusion); to reduce the need for blood transfusions in adults with moderate anaemia who are about to undergo major orthopaedic (bone) surgery, such as hip surgery. It is used in patients with normal blood iron levels who could experience complications from a blood transfusion, if they do not donate their own blood before surgery and are expected to lose 900 to 1,800 ml of blood; to treat anaemia in adults with myelodysplastic syndromes (conditions in which the production of healthy blood cells is defective). Epoetin Alfa Hexal is used when patients are at low or intermediate risk of developing acute myeloid leukaemia and have low levels of the natural hormone erythropoietin.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label].

Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorEpoetin Alfa HexalHexal AgHexal AgIntravenous; Subcutaneous20000 IU/0.5mlNAThe most common side effects with Epoetin Alfa Hexal (which may affect more than 1 in 10 people) are nausea (feeling sick), diarrhoea, vomiting, fever and headache. Flu-like illness may occur especially at the start of treatment.Epoetin Alfa Hexal contains the active substance epoetin alfa and is a ‘biosimilar medicine’.

The reference medicine for Epoetin Alfa Hexal is Eprex/Erypo.to treat anaemia (low red blood cell counts) that is causing symptoms in patients with ‘chronic kidney failure’ (long-term, progressive decrease in the ability of the kidneys to work properly) or other kidney problems; to treat anaemia in adults receiving chemotherapy for certain types of cancer and to reduce the need for blood transfusions; to increase the amount of blood that can be taken in adult patients with moderate anaemia and normal blood iron levels who are going to have an operation and donate their own blood before surgery (autologous blood transfusion); to reduce the need for blood transfusions in adults with moderate anaemia who are about to undergo major orthopaedic (bone) surgery, such as hip surgery. It is used in patients with normal blood iron levels who could experience complications from a blood transfusion, if they do not donate their own blood before surgery and are expected to lose 900 to 1,800 ml of blood; to treat anaemia in adults with myelodysplastic syndromes (conditions in which the production of healthy blood cells is defective). Epoetin Alfa Hexal is used when patients are at low or intermediate risk of developing acute myeloid leukaemia and have low levels of the natural hormone erythropoietin.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorEpoetin Alfa HexalHexal AgHexal AgIntravenous; Subcutaneous40000 IU/1mlNAThe most common side effects with Epoetin Alfa Hexal (which may affect more than 1 in 10 people) are nausea (feeling sick), diarrhoea, vomiting, fever and headache. Flu-like illness may occur especially at the start of treatment.Epoetin Alfa Hexal contains the active substance epoetin alfa and is a ‘biosimilar medicine’. This means that Epoetin Alfa Hexal is highly similar to another biological medicine (the ‘reference medicine’) that is already authorised in the EU. The reference medicine for Epoetin Alfa Hexal is Eprex/Erypo.to treat anaemia (low red blood cell counts) that is causing symptoms in patients with ‘chronic kidney failure’ (long-term, progressive decrease in the ability of the kidneys to work properly) or other kidney problems; to treat anaemia in adults receiving chemotherapy for certain types of cancer and to reduce the need for blood transfusions; to increase the amount of blood that can be taken in adult patients with moderate anaemia and normal blood iron levels who are going to have an operation and donate their own blood before surgery (autologous blood transfusion); to reduce the need for blood transfusions in adults with moderate anaemia who are about to undergo major orthopaedic (bone) surgery, such as hip surgery. It is used in patients with normal blood iron levels who could experience complications from a blood transfusion, if they do not donate their own blood before surgery and are expected to lose 900 to 1,800 ml of blood; to treat anaemia in adults with myelodysplastic syndromes (conditions in which the production of healthy blood cells is defective). Epoetin Alfa Hexal is used when patients are at low or intermediate risk of developing acute myeloid leukaemia and have low levels of the natural hormone erythropoietin.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079].

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing.

Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorEporatioRatiopharm IncRatiopharm IncIntravenous; Subcutaneous1000 IU/0.5mlNAThe most common side effects with Eporatio (seen in between 1 and 10 patients in 100) are shunt thrombosis (clots that can form in blood vessels of patients on dialysis, a blood clearance technique), headache, hypertension (high blood pressure), hypertensive crisis (sudden, dangerously high blood pressure), skin reactions, arthralgia (joint pain) and influenza (flu)-like illness. The active substance in Eporatio, epoetin theta, is a copy of a human hormone called erythropoietin that stimulates the production of red blood cells from the bone marrow. Erythropoietin is produced by the kidneys. In patients receiving chemotherapy or with kidney problems, anaemia can be caused by a lack of erythropoietin, or by the body not responding enough to the erythropoietin it has naturally. The epoetin theta in Eporatio works in the body in the same way as the natural hormone to stimulate red-blood-cell production. It is produced by a method known as ‘recombinant DNA technology’: it is made by a cell that has received a gene (DNA), which makes it able to produce epoetin theta.Eporatio is used to treat anaemia (low levels of red blood cells or haemoglobin) that is causing symptoms. It is used in adults with chronic renal failure (long-term, progressive decrease in the ability of the kidneys to work properly) and in adults with non-myeloid cancer (cancer not originating in the bone marrow) who are receiving chemotherapy (medicines to treat cancer).potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorEporatioRatiopharm IncRatiopharm IncIntravenous; Subcutaneous4000 IU/0.5mlNAThe most common side effects with Eporatio (seen in between 1 and 10 patients in 100) are shunt thrombosis (clots that can form in blood vessels of patients on dialysis, a blood clearance technique), headache, hypertension (high blood pressure), hypertensive crisis (sudden, dangerously high blood pressure), skin reactions, arthralgia (joint pain) and influenza (flu)-like illness. The active substance in Eporatio, epoetin theta, is a copy of a human hormone called erythropoietin that stimulates the production of red blood cells from the bone marrow. Erythropoietin is produced by the kidneys. In patients receiving chemotherapy or with kidney problems, anaemia can be caused by a lack of erythropoietin, or by the body not responding enough to the erythropoietin it has naturally. The epoetin theta in Eporatio works in the body in the same way as the natural hormone to stimulate red-blood-cell production. It is produced by a method known as ‘recombinant DNA technology’: it is made by a cell that has received a gene (DNA), which makes it able to produce epoetin theta.Eporatio is used to treat anaemia (low levels of red blood cells or haemoglobin) that is causing symptoms. It is used in adults with chronic renal failure (long-term, progressive decrease in the ability of the kidneys to work properly) and in adults with non-myeloid cancer (cancer not originating in the bone marrow) who are receiving chemotherapy (medicines to treat cancer).potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080].

The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorEporatioRatiopharm IncRatiopharm IncIntravenous; Subcutaneous20000 IU/1.0mlNAThe most common side effects with Eporatio (seen in between 1 and 10 patients in 100) are shunt thrombosis (clots that can form in blood vessels of patients on dialysis, a blood clearance technique), headache, hypertension (high blood pressure), hypertensive crisis (sudden, dangerously high blood pressure), skin reactions, arthralgia (joint pain) and influenza (flu)-like illness. The active substance in Eporatio, epoetin theta, is a copy of a human hormone called erythropoietin that stimulates the production of red blood cells from the bone marrow. Erythropoietin is produced by the kidneys. In patients receiving chemotherapy or with kidney problems, anaemia can be caused by a lack of erythropoietin, or by the body not responding enough to the erythropoietin it has naturally. The epoetin theta in Eporatio works in the body in the same way as the natural hormone to stimulate red-blood-cell production. It is produced by a method known as ‘recombinant DNA technology’: it is made by a cell that has received a gene (DNA), which makes it able to produce epoetin theta.Eporatio is used to treat anaemia (low levels of red blood cells or haemoglobin) that is causing symptoms. It is used in adults with chronic renal failure (long-term, progressive decrease in the ability of the kidneys to work properly) and in adults with non-myeloid cancer (cancer not originating in the bone marrow) who are receiving chemotherapy (medicines to treat cancer).potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing.

The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorEprex Sterile Solution 10000iu/1.0mlJanssen PharmaceuticalsJanssen PharmaceuticalsIntravenous; Subcutaneous10000 unit / mLNAheadache joint or muscle aches, pain, or soreness nausea vomiting weight loss sores in the mouth difficulty falling asleep or staying asleep depression muscle spasms runny nose, sneezing, and congestion fever, cough, or chills redness, swelling, pain, or itching at the injection spotEpoetin alfa injection products come as a solution (liquid) to inject subcutaneously (just under the skin) or intravenously (into a vein).

Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorEprex Sterile Solution 20000iu/mlJanssen PharmaceuticalsJanssen PharmaceuticalsIntravenous; Subcutaneous20000 unit / mLNAheadache joint or muscle aches, pain, or soreness nausea vomiting weight loss sores in the mouth difficulty falling asleep or staying asleep depression muscle spasms runny nose, sneezing, and congestion fever, cough, or chills redness, swelling, pain, or itching at the injection spotEpoetin alfa injection products come as a solution (liquid) to inject subcutaneously (just under the skin) or intravenously (into a vein).

When epoetin alfa injection products are used to decrease the risk that blood transfusions will be required due to surgery, it is sometimes injected once daily for 10 days before surgery, on the day of surgery and for 4 days after surgery. Alternatively, epoetin alfa injection products are sometimes injected once weekly, beginning 3 weeks before surgery and on the day of surgery.Epoetin alfa injection products are used to treat anemia (a lower than normal number of red blood cells) in people with chronic kidney failure (condition in which the kidneys slowly and permanently stop working over a period of time). Epoetin alfa injection products are also used to treat anemia caused by chemotherapy in people with certain types of cancer or caused by zidovudine (AZT, Retrovir, in Trizivir, in Combivir), a medication used to treat human immunodeficiency virus (HIV). potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079].

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing.

It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorEprex Sterile Solution 5000iu/0.5mlJanssen PharmaceuticalsJanssen PharmaceuticalsIntravenous; Subcutaneous5000 unit / 0.5 mLNAheadache joint or muscle aches, pain, or soreness nausea vomiting weight loss sores in the mouth difficulty falling asleep or staying asleep depression muscle spasms runny nose, sneezing, and congestion fever, cough, or chills redness, swelling, pain, or itching at the injection spotEpoetin alfa injection products come as a solution (liquid) to inject subcutaneously (just under the skin) or intravenously (into a vein).

The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorNeorecormonRoche Registration Gmb HRoche Registration Gmb HIntravenous; Subcutaneous50000 IUNAThe types of side effects seen with NeoRecormon depend on the cause of the patient’s anaemia. The most common side effects (seen in between 1 and 10 patients in 100) are hypertension (high blood pressure), headache and thromboembolic events (formation of blood clots in the blood vessels).The active substance in NeoRecormon, epoetin beta, is a copy of a human hormone called erythropoietin. Erythropoietin is produced by the kidneys and stimulates the production of red blood cells from the bone marrow. In patients receiving chemotherapy or with chronic renal failure, anaemia can be caused by a lack of erythropoietin, or by the body not responding enough to the erythropoietin it has naturally. The epoetin beta in NeoRecormon works in the body in the same way as the natural hormone to stimulate red blood cell production.NeoRecormon is used in the following situations: to treat anaemia (low red blood cell counts) that is causing symptoms in adults and children with chronic renal failure (long-term, progressive decrease in the ability of the kidneys to work properly); to prevent anaemia in premature babies; to treat anaemia that is causing symptoms in adults who are receiving chemotherapy for ‘non-myeloid’ cancer (cancer that does not affect the bone marrow); to increase the amount of blood that can be taken from adult patients with moderate anaemia who are going to have an operation and need to have a supply of their own blood before surgery (autologous blood transfusion).This is only done when blood storage procedures are not available or are insufficient because the surgery requires a large volume of blood.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079].

The most common side effects (seen in between 1 and 10 patients in 100) are hypertension (high blood pressure), headache and thromboembolic events (formation of blood clots in the blood vessels).The active substance in NeoRecormon, epoetin beta, is a copy of a human hormone called erythropoietin. Erythropoietin is produced by the kidneys and stimulates the production of red blood cells from the bone marrow. In patients receiving chemotherapy or with chronic renal failure, anaemia can be caused by a lack of erythropoietin, or by the body not responding enough to the erythropoietin it has naturally. The epoetin beta in NeoRecormon works in the body in the same way as the natural hormone to stimulate red blood cell production.NeoRecormon is used in the following situations: to treat anaemia (low red blood cell counts) that is causing symptoms in adults and children with chronic renal failure (long-term, progressive decrease in the ability of the kidneys to work properly); to prevent anaemia in premature babies; to treat anaemia that is causing symptoms in adults who are receiving chemotherapy for ‘non-myeloid’ cancer (cancer that does not affect the bone marrow); to increase the amount of blood that can be taken from adult patients with moderate anaemia who are going to have an operation and need to have a supply of their own blood before surgery (autologous blood transfusion).This is only done when blood storage procedures are not available or are insufficient because the surgery requires a large volume of blood.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing.

The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorNeorecormonRoche Registration Gmb HRoche Registration Gmb HIntravenous; Subcutaneous4000 IUNAThe types of side effects seen with NeoRecormon depend on the cause of the patient’s anaemia. The most common side effects (seen in between 1 and 10 patients in 100) are hypertension (high blood pressure), headache and thromboembolic events (formation of blood clots in the blood vessels).The active substance in NeoRecormon, epoetin beta, is a copy of a human hormone called erythropoietin. Erythropoietin is produced by the kidneys and stimulates the production of red blood cells from the bone marrow. In patients receiving chemotherapy or with chronic renal failure, anaemia can be caused by a lack of erythropoietin, or by the body not responding enough to the erythropoietin it has naturally. The epoetin beta in NeoRecormon works in the body in the same way as the natural hormone to stimulate red blood cell production.NeoRecormon is used in the following situations: to treat anaemia (low red blood cell counts) that is causing symptoms in adults and children with chronic renal failure (long-term, progressive decrease in the ability of the kidneys to work properly); to prevent anaemia in premature babies; to treat anaemia that is causing symptoms in adults who are receiving chemotherapy for ‘non-myeloid’ cancer (cancer that does not affect the bone marrow); to increase the amount of blood that can be taken from adult patients with moderate anaemia who are going to have an operation and need to have a supply of their own blood before surgery (autologous blood transfusion).This is only done when blood storage procedures are not available or are insufficient because the surgery requires a large volume of blood.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorNeorecormon GuardRoche Registration Gmb HRoche Registration Gmb HIntravenous; Subcutaneous10000 IUNAThe types of side effects seen with NeoRecormon depend on the cause of the patient’s anaemia. The most common side effects (seen in between 1 and 10 patients in 100) are hypertension (high blood pressure), headache and thromboembolic events (formation of blood clots in the blood vessels).The active substance in NeoRecormon, epoetin beta, is a copy of a human hormone called erythropoietin. Erythropoietin is produced by the kidneys and stimulates the production of red blood cells from the bone marrow. In patients receiving chemotherapy or with chronic renal failure, anaemia can be caused by a lack of erythropoietin, or by the body not responding enough to the erythropoietin it has naturally. The epoetin beta in NeoRecormon works in the body in the same way as the natural hormone to stimulate red blood cell production.NeoRecormon is used in the following situations: to treat anaemia (low red blood cell counts) that is causing symptoms in adults and children with chronic renal failure (long-term, progressive decrease in the ability of the kidneys to work properly); to prevent anaemia in premature babies; to treat anaemia that is causing symptoms in adults who are receiving chemotherapy for ‘non-myeloid’ cancer (cancer that does not affect the bone marrow); to increase the amount of blood that can be taken from adult patients with moderate anaemia who are going to have an operation and need to have a supply of their own blood before surgery (autologous blood transfusion).This is only done when blood storage procedures are not available or are insufficient because the surgery requires a large volume of blood.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary.

The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label].

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand.

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label].

The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorProcritJanssen Products, LPJanssen Products, LPIntravenous; Subcutaneous20000 [iU]/1mLPROCRIT is contraindicated in patients with: Uncontrolled hypertension Pure red cell aplasia (PRCA) that begins after treatment with PROCRIT or other erythropoietin protein drugs.

It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label].

Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label].

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days).

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label].

The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label].

Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label].

In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label].

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days).

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label].

The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorSilapoStada Arzneimittel AgStada Arzneimittel AgIntravenous; Subcutaneous4000 IU/0.4mlNAThe most common side effects with Silapo (which may affect more than 1 in 100 people) are headache and increased blood pressure.

Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorSilapoStada Arzneimittel AgStada Arzneimittel AgIntravenous; Subcutaneous8000 IU/0.8mlNAThe most common side effects with Silapo (which may affect more than 1 in 100 people) are headache and increased blood pressure. Silapo contains the active substance epoetin zeta and is a ‘biosimilar’ medicine. This means that Silapo is highly similar to another biological medicine (the ‘reference medicine’) that is already authorised in the EU. The reference medicine for Silapo is Eprex/Erypo, which contains epoetin alfa.to treat anaemia (low red blood cell counts) that is causing symptoms in patients with chronic renal failure (long-term, decreasing ability of the kidneys to work properly) or other kidney problems; to treat anaemia in adults receiving chemotherapy to treat certain types of cancer and to reduce the need for blood transfusions; to increase the amount of blood that patients with moderate anaemia can self-donate before surgery, so that their own blood can be given back to them during or after surgery; to reduce the need for blood transfusions in adults with moderate anaemia who are about to have major orthopaedic (bone) surgery, such as hip surgery. It is used in patients with normal blood iron levels who could experience complications from a blood transfusion, if they do not donate their own blood before surgery and are expected to lose 900 to 1,800 ml of blood; to treat anaemia in adults with myelodysplastic syndromes (conditions in which the production of healthy blood cells is defective). Silapo is used when patients are at low or intermediate risk of developing acute myeloid leukaemia and have low levels of the natural hormone erythropoietin.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079].

The reference medicine for Silapo is Eprex/Erypo, which contains epoetin alfa.to treat anaemia (low red blood cell counts) that is causing symptoms in patients with chronic renal failure (long-term, decreasing ability of the kidneys to work properly) or other kidney problems; to treat anaemia in adults receiving chemotherapy to treat certain types of cancer and to reduce the need for blood transfusions; to increase the amount of blood that patients with moderate anaemia can self-donate before surgery, so that their own blood can be given back to them during or after surgery; to reduce the need for blood transfusions in adults with moderate anaemia who are about to have major orthopaedic (bone) surgery, such as hip surgery. It is used in patients with normal blood iron levels who could experience complications from a blood transfusion, if they do not donate their own blood before surgery and are expected to lose 900 to 1,800 ml of blood; to treat anaemia in adults with myelodysplastic syndromes (conditions in which the production of healthy blood cells is defective). Silapo is used when patients are at low or intermediate risk of developing acute myeloid leukaemia and have low levels of the natural hormone erythropoietin.potassium;[2-butyl-5-chloro-3-[[4-[2-(1,2,3-triaza-4-azanidacyclopenta-2,5-dien-5-yl)phenyl]phenyl]methyl]imidazol-4-yl]methanolNALinkLinkNA

A half-life of approximately 6 hours has been reported in children [F85]., **Adult and paediatric patients with CRF:** The elimination half life following intravenous administration ranges from 4 to 13 hours, which is about 20% longer in CRF patients than that in healthy subjects. The half life is reported to be similar between adult patients receiving or not receiving dialysis [FDA Label]. , **Cancer patients receiving cyclic chemotherapy:** Following subcutaneous administration, the average half life is 40 hours with range of 16 to 67 hours [FDA Label].Erythropoietin (EPO) is a growth factor produced in the kidneys that stimulates the production of red blood cells. It works by promoting the division and differentiation of committed erythroid progenitors in the bone marrow [FDA Label]. Epoetin alfa (Epoge) was developed by Amgen Inc. in 1983 as the first rhEPO commercialized in the United States, followed by other alfa and beta formulations. Epoetin alfa is a 165-amino acid erythropoiesis-stimulating glycoprotein produced in cell culture using recombinant DNA technology and is used for the treatment of patients with anemia associated with various clinical conditions, such as chronic renal failure, antiviral drug therapy, chemotherapy, or a high risk for perioperative blood loss from surgical procedures [FDA Label]. It has a molecular weight of approximately 30,400 daltons and is produced by mammalian cells into which the human erythropoietin gene has been introduced. The product contains the identical amino acid sequence of isolated natural erythropoietin and has the same biological activity as the endogenous erythropoietin. Epoetin alfa biosimilar, such as Retacrit (epoetin alfa-epbx or epoetin zeta), has been formulated to allow more access to treatment options for patients in the market [L2784]. The biosimilar is approved by the FDA and EMA as a safe, effective and affordable biological product and displays equivalent clinical efficacy, potency, and purity to the reference product [A7504]. Epoetin alfa formulations can be administered intravenously or subcutaneously.Indicated in adult and paediatric patients for the treatment of anemia due to Chronic Kidney Disease (CKD) in patients on dialysis and not on dialysis, treatment of anemia due to zidovudine in patients with HIV-infection, treatment of anemia due to the effects of concomitant myelosuppressive chemotherapy, and upon initiation, there is a minimum of two additional months of planned chemotherapy, reduction of allogeneic RBC transfusions in patients undergoing elective, noncardiac, nonvascular surgery.Erythropoietin and epoetin alfa are involved in the regulation of erythrocyte differentiation and the maintenance of a physiological level of circulating erythrocyte mass. It is reported to increase the reticulocyte count within 10 days of initiation, followed by increases in the RBC count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [F85]. Depending on the dose administered, the rate of hemoglobin increase may vary. In patients receiving hemodialysis, a greater biologic response is not observed at doses exceeding 300 Units/kg 3 times weekly [F85]. Epoetin alfa serves to restore erythropoietin deficiency in pathological and other clinical conditions where normal production of erythropoietin is impaired or compromised. In anemic patients with chronic renal failure (CRF), administration with epoetin alfa stimulated erythropoiesis by increasing the reticulocyte count within 10 days, followed by increases in the red cell count, hemoglobin, and hematocrit, usually within 2 to 6 weeks [FDA Label]. Epoetin alfa was shown to be effective in increasing hematocrit in zidovudine-treated HIV-infected patients and anemic cancer patients undergoing chemotherapy [FDA Label].Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways [A33079]. The affinity (Kd) of EPO for its receptor on human cells is ~100 to 200 pM [A33080]. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is induced which brings EPO-R-associated Janus family tyrosine protein kinase 2 (JAK2) molecules into close proximity. JAK2 molecules are subsequently activated via phosphorylation, then phosphorylate tyrosine residues in the cytoplasmic domain of the EPO-R that serve as docking sites for Src homology 2-domain-containing intracellular signaling proteins [A33079]. The signalling proteins include STAT5 that once phosphorylated by JAK2, dissociates from the EPO-R, dimerizes, and translocates to the nucleus where they serve as transcription factors to activate target genes involved in cell division or differentiation, including the apoptosis inhibitor Bcl-x [A33079]. The inhibition of apoptosis by the EPO-activated JAK2/STAT5/Bcl-x pathway is critical in erythroid differentiation. Via JAK2-mediated tyrosine phosphorylation, erythropoietin and epoetin alfa also activates other intracellular proteins involved in erythroid cell proliferation and survival, such as Shc , phosphatidylinositol 3-kinase (PI3K), and phospholipase C-1 [A33079].Overdose from epoetin alfa include signs and symptoms associated with an excessive and/or rapid increase in hemoglobin concentration, including cardiovascular events. Patients with suspected or known overdose should be monitored closely for cardiovascular events and hematologic abnormalities. Polycythemia should be managed acutely with phlebotomy, as clinically indicated. Following resolution of the overdose, reintroduction of epoetin alfa therapy should be accompanied by close monitoring for evidence of rapid increases in hemoglobin concentration (>1 gm/dL per 14 days). In patients with an excessive hematopoietic response, reduce the dose in accordance with the recommendations described in the drug label [FDA Label].Binding of erythropoietin and epoetin alfa to EPO-R leads to cellular internalization, which involves the degradation of the ligand. Erythropoietin and epoetin alfa may also be degraded by the reticuloendothelial scavenging pathway or lymphatic system [A33080].The time to reach peak concentration is slower via the subcutaneous route than the intravenous route which ranges from 20 to 25 hours, and the peak is always well below the peak achieved using the intravenous route (5–10% of those seen with IV administration) [A33080, L85]. The bioavailability of subcutaneous injectable erythropoietin is much lower than that of the intravenously administered product and is approximately 20-40% [A33080, L85]. **Adult and paediatric patients with CRF:** Following subcutaneous administration, the peak plasma levels are achieved within 5 to 24 hours [FDA Label]. **Cancer patients receiving cyclic chemotherapy:** The average time to reach peak plasma concentration was approximately 13.3 ± 12.4 hours after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing. The Cmax is expected be 3- to 7- fold higher and the Tmax is expected to be 2- to 3-fold longer in patients receiving a 40,000 Units SC weekly dosing regimen [FDA Label].In healthy volunteers, the volume of distribution of intravenous epoetin alfa was generally similar to the plasma volume (range of 40–63.80 mL/kg), indicating limited extravascular distribution [A33080, A33076].**Healthy volunteers: ** In male volunteers receiving intravenous epoetin alfa, the total body clearance was approximately 8.12 ± 1.00 mL/h/kg [A33076]. **Cancer patients receiving cyclic chemotherapy:** The average clearance was approximately 20.2 ± 15.9 mL/h/kg after 150 Units/kg three times per week (TIW) subcutaneous (SC) dosing [FDA Label]. The patients receiving a 40,000 Units SC weekly dosing regimen display a lower clearance (9.2 ± 4.7 mL/h/kg) [FDA Label].NANANANANAErythropoietin receptorSilapoStada Arzneimittel AgStada Arzneimittel AgIntravenous; Subcutaneous40000 IU/1.0mlNAThe most common side effects with Silapo (which may affect more than 1 in 100 people) are headache and increased blood pressure.

In animal models C5 inhibition has been found to significantly reduce myocardial infarct size and decrease cellular necrosis and apoptosis. Pexelizumab is a humanized, monoclonal, single-chain antibody fragment that inhibits C5, thereby blocking its cleavage into active forms.Although inflammation is a normal response, continued exposure to foreign surfaces, toxic antigens, and tissue injury results in pathologic local and systemic inflammation (SIRS). This response involves multiple humoral and cellular components, including the coagulation (Factor XII, thrombin, Proteins C and S, platelets) and complement systems, cytokines (TNF-alpha, interleukins), leukocytes, monocytes, adhesion molecules (ICAM-1), and endothelial cells, among others. The complement system is a group of glycoproteins, which, when activated, results in the formation of C3-convertase, which converts C3 to C3a and C3b. C3a cleaves C5 to C5a and C5b. C5b, in conjunction with C6, C7, C8, and C9, forms the membrane attack or terminal complement complex (TCC) C5b-9.

It is clinically useful in early detection and localization of bleeding sites, and preoperative diagnosis of hemangioma [A32178, A32179]. Autologous red blood cells are radiolabeled with sodium pertechnetate Tc 99m in the reaction vial.

Blood abnormalities can be detected during gamma scintigraphic imaging.Autologous red blood cells (RBC) are collected from the patient and put into the reaction vial for radiolabeling, followed by anticoagulation with heparin or Anticoagulant Citrate Dextrose Solution (ACD). In the reaction vial, stannous ion diffuses across the RBC membrane and accumulates intracellularly. Sodium hypochlorite, which does not cross the RBC membrane, is then added to the reaction vial to oxidize the extracellular stannous ion. Finally, sodium pertechnetate Tc 99m is added to the oxidized reaction vial to diffuse across the red blood cell membrane and be reduced by the intracellular stannous ion. Upon reduction, Tc 99m cannot diffuse out of the RBC.

Blood abnormalities can be detected during gamma scintigraphic imaging.Autologous red blood cells (RBC) are collected from the patient and put into the reaction vial for radiolabeling, followed by anticoagulation with heparin or Anticoagulant Citrate Dextrose Solution (ACD). In the reaction vial, stannous ion diffuses across the RBC membrane and accumulates intracellularly. Sodium hypochlorite, which does not cross the RBC membrane, is then added to the reaction vial to oxidize the extracellular stannous ion. Finally, sodium pertechnetate Tc 99m is added to the oxidized reaction vial to diffuse across the red blood cell membrane and be reduced by the intracellular stannous ion. Upon reduction, Tc 99m cannot diffuse out of the RBC. Technetium Tc 99m-labeled red blood cells are injected again into the patient for gamma scintigraphic imaging [FDA Label].No long term animal studies have been performed to evaluate carcinogenic or mutagenic potential or to determine the effects on male or female fertility [FDA Label].NANAFollowing intravenous injection, the technetium Tc 99m-labeled red blood cells distribute within the blood pool with an estimated volume of distribution of approximately 5.6% of bodyweight [FDA Label].NARadiopharmaceutical ActivityNANANANANANANANANANANANANANANANALinkNANA

It prevents leukocyte migration through the gap junctions of endothelial cells. FX06 has proven safe in acute and subchronic toxicological studies and recently entered clinical development. It is being developed by Fibrex Medical Inc.Investigated for use/treatment in cardiac reperfusion injury and myocardial infarction.NAFX06 has a novel mechanism of action: it is a competitive inhibitor of the binding of fibrin E1 fragments to vascular endothelial (VE)-cadherin. Through this inhibition, it potently blocks the transmigration of inflammatory leukocytes through the endothelial barrier and prevents the downstream release of tissue-damaging mediators.NANANANANANANANANANACadherin-5NANANANANANANANANANANALinkNANA
