Background

CD79B is a cell-surface antigen expressed on mature B cells but absent on plasma cells. A majority of mature malignancies of B-cell origin, including non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia, express CD79B and demonstrate rapid internalization of anti-CD79B antibodies. Polatuzumab vedotin is an antibody-drug conjugate composed of the anti-mitotic agent monomethyl auristatin E (MMAE) covalently conjugated to a CD79b-directed monoclonal antibody.
