Pharmacology
Alemtuzumab is a humanized IgG1 kappa monoclonal antibody that binds to CD52, a cell surface antigen on T and B lymphocytes, natural killer cells, monocytes, and macrophages, resulting in antibody-dependent cellular cytolysis and complement-mediated lysis; the precise mechanism by which this exerts therapeutic effects in MS is unknown.
Prednisone is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties that suppresses inflammatory processes (edema, capillary dilatation, leukocyte migration), modifies immune responses, and produces metabolic effects including promotion of gluconeogenesis, protein catabolism, and altered calcium and electrolyte balance.
