ARZERRA® combination for Frontline Treatment of CLL

The FDA on April 17, 2014 approved ARZERRA® (Ofatumumab) in combination with LEUKERAN® (Chlorambucil), for the treatment of previously untreated patients with Chronic Lymphocytic Leukemia (CLL), for whom FLUDARA® (Fludarabine) based therapy is considered inappropriate. ARZERRA® is a second generation fully human IgG 1 monoclonal antibody and unlike RITUXAN® (Rituximab) which is a chimeric monoclonal antibody, targets a different region (different epitope) of the CD20 molecule. The combination of ARZERRA® given along with LEUKERAN® significantly improved Progression Free Survival, Response Rates and duration of response, compared to single agent LEUKERAN®. ARZERRA®  in combination with LEUKERAN®  is a clinically important milestone, in the management of elderly patients with CLL.
