DescriptionEfalizumab is Humanized IgG1 kappa isotype monoclonal antibody that binds to human CD11a. It is produced in a Chinese hamster ovary mammalian cell expression system in a nutrient medium containing the antibiotic gentamicin.
Indication/DiseaseIndcated in treatment of adult patients with moderate to severe chronic plaque psoriasis, who are candidates for phototherapy or systemic therapy.
PharmacodynamicsIn psoriatic skin, ICAM-1 cell surface expression is upregulated on endothelium and keratinocytes. Raptiva inhibits the binding of LFA-1 to the intercellular adhesion molecule-1 (ICAM-1), thereby inhibiting the adhesion of leukocytes to other cell types.
Mechanism of ActionEfalizumab binds to CD11a, a subunit of leukocyte function antigen-1 (LFA-1), which is expressed on all leukocytes. As a result efalizumab decreases cell surface expression of CD11a.
