What this study is about

This trial is testing whether adding venetoclax to a Bruton Tyrosine Kinase Inhibitor (BTKi) pill improves outcomes for people with CLL or SLL. Participants will continue their current BTKi treatment as long as it's working, or they may receive the BTKi plus venetoclax for one year. After that period, both pills would be stopped and participants will be closely monitored.
