Overview
The goal of this study is to compare how well sonrotoclax plus obinutuzumab works versus venetoclax plus rituximab in treating adults with relapsed and/or refractory (R/R) chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). The study will also compare how well sonrotoclax plus rituximab works versus venetoclax plus rituxumab in treating adults with R/R CLL/SLL. The safety of these treatments will also be assessed.

Our company, previously known as BeiGene, is now officially BeOne Medicines. Because some of our older studies were sponsored under the name BeiGene, you may see both names used for this study on this website.
