Description | Human recombinant antihemophilic factor or Factor VIII of 2332 residues(glycosylated) is produced by CHO cells. |
Indication/Disease | For the treatment of hemophilia A, von Willebrand disease and Factor XIII deficiency. |
Pharmacodynamics | Antihemophilic Factor binds factor IXa along with calcium and phospholipid, this complex converts factor X to factor Xa to facilitate clotting cascade. |
Mechanism of Action | Antihemophilic factor is a protein found in normal plasma which is necessary for clot formation. The administration of AHF provides an increase in plasma levels of AHF and can temporarily correct the coagulation defect of patients with hemophilia A. |
Toxicity | The highest toxicity is the risk of viral hepatitis transmition as well as intravascular hemolyisis can occur if large or frequent doses are used in blood groups A, B or AB |
Metabolism | The metabolism of the human antihemophilic factor is identical to the normal inactivation and elimination pathway of the natural coagulation factor VIII. After activation, the human antihemophilic factor gets metabolized by activated protein C in R336 and R562 and this action inactivates this cofactor. The proteolysis generates two major fragments which are recognized by an anti-factor VIII A2 domain antibody. This process is followed by a further degradation into smaller fragments |
Absorption | After intravenous administration of the human antihemophilic factor the values of Cmax, AUC and Tmax were 100 IU/ml, 1450 IU h/ml and 0.43 h respectively. In a second clinical trial, the treatment was administered for six months and the values of Cmax, AUC and Tmax were 99 units/ 100 ml, 1471 units h/ 100ml and 16 h, respectively. |
| The central and peripheral volume of distribution in adults weight an average of 68 kg were 2.81 L and 1.90 L respectively. |
Clearance | 0.15 L/h |

Brand Description | Bayer |
Prescribed For | KOVALTRY, Antihemophilic Factor (Recombinant), is a recombinant, human DNA sequence derived, full length Factor VIII concentrate indicated for use in adults and children with hemophilia A (congenital Factor VIII deficiency) |
Chemical Name | NA |
Formulation | The active substance in KOVALTRY is the unmodified full length recombinant Factor VIII glycoprotein comprising the human derived amino acid sequence. Post-translational modifications are similar to those of endogenous Factor VIII including glycosylation sites and sulfation of tyrosine sites. Manufacturing and quality controls ensure that both galactose-alpha-1,3-galactose (alpha-Gal) and N-glycolyl neuraminic acid (NGNA) content are below the 1% limit of detection established for each analytical method. |
Physical Appearance | sterile, non-pyrogenic, white to slightly yellow powder |
Route of Administration | Intravenous Injection |
Recommended Dosage | Required dose (IU) = body weight (kg) x desired Factor VIII rise (% of normal or IU/dL) x reciprocal of expected/observed recovery (e.g., 0.5 for a recovery of 2 IU/dL per IU/kg) |
Contraindication | KOVALTRY is contraindicated in patients who have a history of hypersensitivity reactions to the active substance, to any of the excipients, or to mouse or hamster proteins |
Side Effects | headache fever itching injection site reactions insomnia rash abdominal pain or discomfort indigestion swollen lymph nodes heart palpitations dizziness allergic skin reactions changes in taste hives, and flushing. |
