An open-label phase 1b study of obinutuzumab plus lenalidomide in relapsed/refractory follicular B-cell lymphoma.

ABSTRACT: Obinutuzumab is a type II anti-CD20 monoclonal antibody that enhances antibody-dependent cellular cytotoxicity better than rituximab. Given promising results with lenalidomide and rituximab, this phase 1b study assessed the safety and efficacy of lenalidomide combined with obinutuzumab (GALEN). Patients age ≥18 years with relapsed or refractory (R/R) follicular lymphoma (FL) after rituximab-containing therapy received escalating doses (10 [n = 7], 15 [n = 3], 20 [n = 6], and 25 mg [n = 3]) of daily oral lenalidomide on days 1 to 21 of cycle 1 and on days 2 to 22 of cycles 2 to 6 (28-day cycles). Obinutuzumab 1000 mg IV was administered on days 8, 15, and 22 (cycle 1) and on day 1 (cycles 2-6). Dose was escalated in a 3 + 3 design based on dose-limiting toxicity (DLT) during cycle 1 to esta
