Description

Summary

The purpose of this open-label, multicenter, randomized, Phase III study is to evaluate the benefit of venetoclax in combination with rituximab compared with bendamustine in combination with rituximab in participants with relapsed or refractory CLL. Participants will be randomly assigned in 1:1 ratio to receive either venetoclax + rituximab (Arm A) or bendamustine + rituximab (Arm B).
