New hope for hard-to-treat blood cancers: phase 3 trial pits NX-5948 against standard therapy
NCT ID NCT07516093
First seen Jun 27, 2026 · Last updated Sep 01, 2026 · Updated 2 times
Summary
This study compares two drugs, NX-5948 and pirtobrutinib, in about 620 people with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) whose cancer has returned or stopped responding after prior treatment with a BTK inhibitor. The main goal is to see which drug better delays disease progression or death. Participants will be randomly assigned to one of the two treatments.
