Obinutuzumab in chronic lymphocytic leukemia.

Obinutuzumab is the second next-generation monoclonal anti-CD20 antibody (after ofatumumab) to enter clinical practice in chronic lymphocytic leukemia. Its superiority in association with chlorambucil as compared with chlorambucil alone has led to its approval as a first-line treatment for chronic lymphocytic leukemia, for patients who are not candidates for a more intensive treatment.
