Phase 3 Study Comparing Sonrotoclax Plus Zanubrutinib With Placebo Plus Zanubrutinib in Adults With Relapsed or Refractory Mantle Cell Lymphoma

What this Trial Is About

Researchers are evaluating the combination of sonrotoclax plus zanubrutinib compared with zanubrutinib plus placebo in adults with relapsed or refractory mantle cell lymphoma MCL. This Phase 3 randomized, double-blind study aims to compare how well these treatments work and assess their safety in this patient population. The study is sponsored by BeOne Medicines and focuses on patients who have previously received 1 to 5 prior systemic therapies including anti-CD20 monoclonal antibody or chemoimmunotherapy. Participants will receive either sonrotoclax plus zanubrutinib or placebo plus zanubrutinib, both administered orally. The study has two groups one receiving the combination of sonrotoclax and zanubrutinib, and the other receiving zanubrutinib with placebo. Treatment continues as per protocol, and the study includes detailed assessments of response and safety over time. During the study, participants will be monitored for progression-free survival as the primary outcome, assessed by an independent review committee over approximately 41 months. Secondary outcomes include overall survival, response rates, duration of response, health-related quality of life, and adverse events up to around 58 months. Regular evaluations will be conducted to assess disease status, quality of life, and safety throughout the trial, which is planned to complete by 2032.
