May 2, 2024 updated by: Genentech, Inc.
An Open-Label, Multicenter, Phase I/II Trial Evaluating the Safety, Efficacy, and Pharmacokinetics of Escalating Doses of Mosunetuzumab (BTCT4465A) as a Single Agent and Combined With Atezolizumab in Patients With Relapsed or Refractory B-Cell Non-Hodgkin's Lymphoma and Chronic Lymphocytic Leukemia
This is a Phase 1/2 dose-escalation study of BTCT4465A (Mosunetuzumab) administered as a single agent and in combination with atezolizumab in participants with relapsed or refractory B-cell NHL and CLL.
The study will consist of a dose-escalation stage and an expansion stage where participants will be enrolled into indication-specific cohorts.
