LEMTRADA (alemtuzumab)

CD52-directed Antibody Interactions
CNS Approved 2001-05-07

LEMTRADA is indicated for the treatment of Multiple Sclerosis.

Source: FDA Label • Sanofi • CD52-directed Cytolytic Antibody

How LEMTRADA Works

Alemtuzumab binds to CD52, a cell surface antigen present on T and B lymphocytes, natural killer cells, monocytes, and macrophages. Although the precise therapeutic mechanism is unknown, binding to these lymphocytes results in antibody-dependent cellular cytolysis and complement-mediated lysis. These processes lead to the destruction of the targeted immune cells. This cytolytic action is presumed to be the basis for the drug's effect in treating multiple sclerosis.
