Study Summary

Researchers are looking for new ways to treat people with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). CLL and SLL are types of blood cancer. Researchers want to know if people who take nemtabrutinib compared to those who take the standard treatments in this study will live longer without their cancer growing, spreading or returning (progression free survival).

Primary Outcome

PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first. PD is evaluated per International Workshop on Chronic Lymphocytic Leukemia (iwCLL) criteria 2018 as assessed by blinded independent central review (BICR).
