Who this trial is looking for
This trial is looking for adults with chronic lymphocytic leukemia or small lymphocytic lymphoma who have not received any treatment before. Participants will take nemtabrutinib or another medication chosen by the doctor.
Are You a Good Fit for This Trial?
You may be able to join if
I have been diagnosed with chronic lymphocytic leukemia or small lymphocytic lymphoma.
My disease is active and requires treatment.
I have at least one marker of disease burden.
I can swallow and keep down oral medication.
I have an ECOG performance status of 0 to 2.
I am hepatitis B surface antigen positive but have been on antiviral therapy and have an undetectable viral load.
I am hepatitis C virus negative.
I have HIV and meet all eligibility criteria.
You may not be able to join if
I have an active hepatitis B or hepatitis C infection.
I have gastrointestinal problems that affect drug absorption.
I have been diagnosed with Richter Transformation or have active central nervous system involvement.
I have had an AIDS-related opportunistic infection in the past year.
I have significant cardiovascular disease.
I am allergic to nemtabrutinib or have contraindications to ibrutinib or acalabrutinib.

The goal of this study is to evaluate nemtabrutinib compared with investigator's choice of ibrutinib or acalabrutinib in participants with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) who have not received any prior therapy. The primary hypotheses are that (1) nemtabrutinib is non-inferior to ibrutinib or acalabrutinib with respect to objective response rate (ORR) per Intern…
The goal of this study is to evaluate nemtabrutinib compared with investigator's choice of ibrutinib or acalabrutinib in participants with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) who have not received any prior therapy. The primary hypotheses are that (1) nemtabrutinib is non-inferior to ibrutinib or acalabrutinib with respect to objective response rate (ORR) per International Workshop on Chronic Lymphocytic Leukemia (iwCLL) Criteria 2018 by blinded independent central review (BICR) and (2) nemtabrutinib is superior to ibrutinib or acalabrutinib with respect to progression free survival (PFS) per iwCLL Criteria 2018 by BICR.
