The development of B-cell-depleting anti-CD20 monoclonal antibody (mAb) therapies has led to a better understanding of the role of B and T cells in this disease, and, most importantly, has led to a new appreciation of the central role of B cells in MS pathophysiology. Ofatumumab works by binding to and blocking the action of CD-20, a molecule expressed on the surface of both healthy and leukemic B lymphocytes. In patients with previously untreated chronic lymphocytic leukemia (CLL), ofatumumab caused B-cell depletion in the peripheral blood after six months following the last dose.
