Official title

A Phase 3, Randomized Study to Compare the Efficacy and Safety of Nemtabrutinib Versus Chemoimmunotherapy for Previously Untreated Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma Without TP53 Aberrations

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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).
