BeOne Medicines announced positive topline results from the Phase 3 MANGROVE study evaluating foundational BTK inhibitor Brukinsa - zanubrutinib - plus rituximab versus bendamustine plus rituximab, or BR, in adult patients with previously untreated mantle cell lymphoma, or MCL. MANGROVE is the first Phase 3, global, randomized trial to evaluate a BTK inhibitor-based chemotherapy-free regimen against standard chemoimmunotherapy in this setting. This pivotal Phase 3 trial builds on the established clinical evidence for Brukinsa in MCL. MANGROVE met its primary endpoint of progression-free survival, demonstrating a highly statistically significant and clinically meaningful improvement for Brukinsa plus rituximab versus BR. This Brukinsa -based, chemotherapy-free regimen led to a 43% reduction in the risk of progression or death. The safety profile of Brukinsa plus rituximab was consistent with the known safety profile of both medicines, with no new safety signals identified. Overall survival, a key secondary endpoint, was immature at the time of this analysis; however, a strong trend in favor of Brukinsa plus rituximab was observed. OS will be tested as part of the final analysis. The company is in discussions with global regulatory authorities with planned submissions in 2H26.

BRUKINSA Plus Rituximab Significantly Improves Outcomes in MCL Patients
- Clinical Trial Success: The MANGROVE study demonstrated that BRUKINSA combined with rituximab reduced the risk of progression or death by 43% compared to the traditional bendamustine plus rituximab regimen (HR=0.57; p<0.0001), marking the first chemotherapy-free standard in frontline MCL treatment and potentially redefining global treatment paradigms.
- Reduced Patient Burden: This chemotherapy-free approach spares patients from approximately two years of frequent infusions, significantly alleviating the treatment burden for older patients and enhancing their quality of life, addressing the urgent need for new therapeutic options.
- Global Regulatory Plans: BeOne Medicines plans to submit applications to global regulatory authorities in the second half of 2026, further advancing BRUKINSA's market access and expected to provide more effective treatment options for MCL patients, thereby enhancing the company's competitiveness in oncology.
- Future Outlook: Full results from the MANGROVE study will be presented at an upcoming medical meeting, which is anticipated to provide additional data support for BRUKINSA's clinical application, solidifying its foundational role in the treatment of B-cell malignancies.
