A Phase IB/II Study Evaluating The Safety, Tolerability and Anti-Tumor Activity of Polatuzumab Vedotin in Combination With Rituximab (R) or Obinutuzumab (G) Plus Bendamustine (B) in Relapsed or Refractory Follicular or Diffuse Large B-Cell Lymphoma
In Brief
A Phase 2 clinical trial evaluating Bendamustine, Obinutuzumab, and 3 other interventions for Lymphoma. Completed, enrolled 331 participants across 62 sites in 13 countries.
Detailed Summary
This study is a multicenter, open-label study of polatuzumab vedotin administered by intravenous (IV) infusion in combination with standard doses of bendamustine (B) and rituximab (R) or obinutuzumab (G) in participants with relapsed or refractory follicular lymphoma (FL) or diffuse large B-cell lymphoma (DLBCL). The study comprises two stages: a Phase Ib safety run-in stage and a Phase II stage. The anticipated time on treatment is 18 weeks for participants with DLBCL and 24 weeks for participants with FL.
