An Evidence-based Review of Anti-CD20 Antibody-containing Regimens for the Treatment of Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia, Diffuse Large B-cell Lymphoma, or Follicular Lymphoma

The present review assessed the reported evidence on the efficacy of anti-CD20 monoclonal antibodies combined with chemotherapy for patients with relapsed or refractory chronic lymphocytic leukemia (CLL), follicular lymphoma (FL), or diffuse large B-cell lymphoma (DLBCL), using a rapid evidence assessment approach. MEDLINE, Embase, and the Cochrane Library were searched from January 1, 1997 to July 14, 2017 (English language only). The data identified from randomized controlled trials or single-arm prospective studies are reported as descriptive study summaries, grouped by anti-CD20 agent and outcome (overall response rate, including complete response and partial response; duration of response; survival, including overall survival and progression-free survival). Of 56 included reports, 32 reported on CLL/small lymphocytic lymphoma, 15 on FL, and 11 on DLBCL. Within the study period, 40, 11, and 7 studies evaluated rituximab, ofatumumab, and obinutuzumab, respectively. Substantially more data were available for rituximab-based combination regimens than for either ofatumumab or obinutuzumab. Moreover, substanti...
