A Study of Venetoclax in Combination With Obinutuzumab in Participants With Chronic Lymphocytic Leukemia

January 7, 2020 updated by: Genentech, Inc.

A Phase Ib Multicenter Dose-Finding and Safety Study of Venetoclax and Obinutuzumab in Patients With Relapsed or Refractory or Previously Untreated Chronic Lymphocytic Leukemia

This multi-center, open-label, dose-finding study will evaluate the safety and pharmacokinetics as well as the preliminary efficacy of venetoclax (GDC-0199; ABT-199) administered in combination with obinutuzumab to participants with relapsed/refractory or previously untreated chronic lymphocytic leukemia (CLL). The study is comprised of two stages for each participant population: a dose-finding stage and a safety-expansion stage. The dose-finding stage will explore multiple doses of venetoclax to be used in combination with a fixed dose of obinutuzumab. The dose-finding stage will also explore two schedules for drug administration, Schedule A (venetoclax introduced before obinutuzumab) and Schedule B (venetoclax introduced after obinutuzumab).
