Study of BGB-16673 for CLL or SLL Previously Treated with BTK and BCL2 Inhibitors

This study is for people with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) whose cancer has returned or didn't respond to previous treatments, specifically those who have already received both BTK inhibitors and BCL2 inhibitors. You would receive either BGB-16673 (an oral drug) or a standard treatment chosen by your doctor, which could be idelalisib plus rituximab, bendamustine plus rituximab, or venetoclax plus rituximab. The main goal is to see if BGB-16673 can help you live longer without your cancer getting worse, compared to the standard treatments. We expect to include about 250 participants in this study. The study is looking for people aged 18 and older with a confirmed diagnosis of CLL or SLL.

Study design

  • Progression-Free Survival (PFS) by Independent Review Committee (IRC)Approximately 36 Months

    PFS is defined as time from the date of randomization to the date of first disease progression or death, whichever occurs first, as determined by IRC using modified 2018 International Workshop on Chronic Lymphocytic Leukemia (iwCLL) criteria for participants with chronic lymphocytic leukemia (CLL) and Lugano classification for participants with small lymphocytic lymphoma (SLL).
