Researchers are investigating the use of lisaftoclax combined with BTK inhibitors in patients with chronic lymphocytic leukemia or small lymphocytic lymphoma CLLSLL who have previously been treated with BTK inhibitors. This global, open-label, phase III study aims to evaluate the effectiveness and safety of this combination compared to BTK inhibitor alone in patients who have been on BTK inhibitor monotherapy for at least 12 months. About 440 participants will be randomly assigned to one of two groups one will receive lisaftoclax together with a BTK inhibitor, and the other will receive only a BTK inhibitor. The study uses a parallel design where participants are allocated equally to each treatment arm to compare outcomes clearly. Both treatments are administered under medical supervision, and the study is open-label, meaning both the researchers and participants know which treatment is given. Participants will be assessed regularly over the course of the study, with evaluations including disease progression measured at 12 months and overall survival also tracked at 12 months. Eligibility screening includes assessments of performance status, bone marrow, kidney, and liver function, as well as consent to follow the study schedule. The research team monitors safety and treatment effects throughout the trial, which is expected to complete by late 2027.
