DescriptionImmunosuppressive dimeric fusion protein that consists of the extracellular CD2-binding portion of the human leukocyte function antigen-3 (LFA-3) linked to the Fc (hinge, CH2 and CH3 domains) portion of human IgG1. Produced by CHO cells, mW is 91.4 kD.
Indication/DiseaseAs an immunosuppressive drug, Alefacept can be used for treatment of moderate to severe chronic plaque psoriasis
PharmacodynamicsInterferes with lymphocyte activation by specifically binding to the lymphocyte antigen, CD2, and inhibiting LFA-3/CD2 interaction. Activation of T lymphocytes involving the interaction between LFA-3 on antigen-presenting cells and CD2 on T lymphocytes plays a role in the pathophysiology of chronic plaque psoriasis. Also causes a reduction in subsets of CD2+ T lymphocytes as well as CD4+ and CD8+ T lymphocytes.
Mechanism of ActionInhibits T-lymphocyte activation and production by binding to the CD2 lymphocyte antigen.
ToxicityWhile it has been found to cross the placenta in monkeys, it is not yet known if it also diffuses into breast milk.

Brand NameAmevive
CompanyAstellas Pharma Inc.
Brand DiscriptionAMEVIVE (alefacept) is a CD2-directed LFA-3/Fc fusion protein that consists of the extracellular CD2-binding portion of the human leukocyte function antigen-3 (LFA-3) linked to the Fc (hinge, CH2 and CH3 domains) portion of human IgGl. Alefacept is produced by recombinant DNA technology in a Chinese Hamster Ovary (CHO) mammalian cell expression system. The molecular weight of alefacept is 91.4 kilodaltons.
Prescribed forAMEVIVE is indicated for the treatment of adult patients with moderate to severe chronic plaque psoriasis who are candidates for systemic therapy or phototherapy.
Chemical NameN.A.
FormulationIt contains alefacept (15 mg), citric acid monohydrate (0.06 mg), glycine (5 mg), sodium citrate dehydrate (3.6 mg), and sucrose (12.5 mg) per 0.5 mL of reconstituted solution.
Physcial AppearnceAMEVIVE is supplied as a sterile, white-to-off-white, preservative-free, lyophilized powder
Route of AdministrationIntramuscular Injection
Recommended DosageThe recommended dose of AMEVIVE® is 15 mg intramuscularly once weekly for 12 weeks. The CD4+ T lymphocyte counts should be measured before initiating dosing.
ContraindicationAMEVIVE should not be administered to patients infected with HIV. AMEVIVE reduces CD4+ T lymphocyte counts, which might accelerate disease progression or increase complications of disease in these patients
Side EffectsLymphopenia, Malignancies, Serious Infections reuiring hospitalization, Hypersenstivity reactions.
