Phase 3 Study Comparing BGB-16673 to Standard Treatments in Adults With Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma Previously Treated With BTK and BCL2 Inhibitors

What this Trial Is About

Researchers are evaluating the efficacy and safety of BGB-16673 compared with the investigators choice of treatments in participants with chronic lymphocytic leukemia CLL or small lymphocytic lymphoma SLL who have previously been treated with both Bruton Tyrosine Kinase inhibitors BTKi and B-cell leukemialymphoma 2 protein inhibitors BCL2i. This study addresses the urgent need for new treatments to extend life and control symptoms such as enlarged lymph nodes, spleen, or liver, night sweats, weight loss, and fever in these patients. Participants will be randomly assigned to receive either BGB-16673 once daily or the investigators choice of treatment, which includes idelalisib plus rituximab for CLL only, bendamustine plus rituximab, or venetoclax plus rituximab retreatment. Treatments will continue until criteria for stopping treatment are met. This is a Phase 3, open-label, randomized study conducted globally with about 250 participants. During the study, participants will undergo regular assessments to monitor disease progression and response to treatment. Researchers will evaluate progression-free survival, overall survival, response rates, duration of response, and quality of life measures over approximately 24 to 36 months. Safety will be closely monitored by tracking treatment-emergent adverse events. Participants involvement includes receiving study medication, regular visits, and various evaluations to assess treatment effects and side effects.
