Summary

This Phase 3 trial is testing an experimental oral drug called BGB-16673 against standard treatments (bendamustine plus rituximab or high-dose methylprednisolone plus rituximab) in 150 people with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who have already been treated with a BTK inhibitor. The main goal is to see if BGB-16673 can delay cancer progression or improve survival. Participants are randomly assigned to receive either the new drug or one of the standard therapies.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
BGB-16673 (an experimental oral drug)
What this could lead to
If successful, this could offer a new treatment option for people with CLL or SLL whose cancer has returned or stopped responding to current BTK inhibitor therapy.
What could go wrong
This is an early-stage Phase 3 trial with only 150 participants, so results may not apply to everyone. The experimental drug may not work better than standard treatments and could have unknown side effects.
