DescriptionHumanized monoclonal antibody specific to lymphocyte antigens. It is a recombinant DNA-derived humanized monoclonal antibody (Campath-1H) that is directed against the 21-28 kD cell surface glycoprotein,CD52. The Campath-1H antibody is an IgG1 kappa with human variable framework and constant regions, and complementarity-determining regions from a murine (rat) monoclonal antibody (Campath-1G). Campath is produced in mammalian cell (Chinese hamster ovary) suspension culture in a medium containing neomycin.
Indication/DiseaseAlemtuzumab (Campath) is a monoclonal antibody therapy used for treatment of B-cell chronic lymphocytic leukemia.
PharmacodynamicsCampath is used to treat leukemia by exploiting antibody mediated lysis of CD52 presenting cells. The CD52 antigen is a cell surface protein found on essentially all B and T lymphocytes, a majority of monocytes, macrophages and most granulocytes. The CD52 antigen is not present on erythrocytes or hematopoetic stem cells. In leukemia there is an excess of B and T cells, so Campath permits selective reduction of lymphocyte populations.
Mechanism of ActionCampath binds to the CD52 antigen present on most B and T lymphocytes. This binding leads to antibody-dependent lysis of leukemic cells.

Brand NameLEMTRADA
CompanySanofi Genzyme, a Division of Sanofi Aventis Canada Inc
Brand DiscriptionLEMTRADA (alemtuzumab) is a recombinant humanized IgG1 kappa monoclonal antibody directed against the cell surface glycoprotein, CD52. Alemtuzumab has an approximate molecular weight of 150kD. LEMTRADA is produced in mammalian cell (Chinese hamster ovary) suspension culture in a nutrient medium containing neomycin. Neomycin is not detectable in the final product.
Prescribed forLEMTRADA is a CD52-directed cytolytic monoclonal antibody indicated for the treatment of patients with relapsing forms of multiple sclerosis (MS). Because of its safety profile, the use of LEMTRADA should generally be reserved for patients who have had an inadequate response to two or more drugs indicated for the treatment of MS.
Chemical NameN.A.
FormulationEach 1 mL of solution contains alemtuzumab 10 mg, dibasic sodium phosphate (1.15 mg), disodium edetate dihydrate (0.0187 mg), polysorbate 80 (0.1 mg), potassium chloride (0.2 mg), potassium dihydrogen phosphate (0.2 mg), sodium chloride (8 mg), and water for injection.
Physcial AppearnceLEMTRADA is a sterile, clear and colorless to slightly yellow, solution (pH 7.2±0.2) for infusion.
Route of AdministrationIntravenous infusion
Recommended DosageAdminister LEMTRADA by Intravenous infusion over 4 hours for 2 treatment courses. First course: 12 mg/day on 5 consecutive days. Second course: 12 mg/day on 3 consecutive days 12 months after first treatment course.
ContraindicationLEMTRADA is contraindicated in patients who are infected with Human Immunodeficiency Virus (HIV) because LEMTRADA causes prolonged reductions of CD4+ lymphocyte counts.
Side EffectsMost common adverse reactions (incidence >= 10% and > interferon beta-1a): rash, headache, pyrexia, nasopharyngitis, nausea, urinary tract infection, fatigue, insomnia, upper respiratory tract infection, herpes viral infection, urticaria, pruritus, thyroid gland disorders, fungal infection, arthralgia, pain in extremity, back pain, diarrhea, sinusitis, oropharyngeal pain, paresthesia, dizziness, abdominal pain, flushing, and vomiting.
