BeOne Medicines Showcases Leadership in B-cell Malignancies at ASH 2025

(BUSINESS WIRE) -- BeOne Medicines Ltd. (Nasdaq: ONC; HKEX: 06160; SSE: 688235), a global oncology company, advances its vision to become the world’s leading oncology company with extensive new data from its differentiated hematology portfolio at the 67^th American Society of Hematology (ASH) Annual Meeting and Exposition in Orlando, Florida, December 6-9. Nearly 50 abstracts have been accepted, including six oral presentations, featuring the company’s three transformative approved and investigational hematology assets – BTK inhibitor BRUKINSA^® (zanubrutinib), BCL2 inhibitor sonrotoclax, and BTK degrader BGB-16673.

Key presentations include:

• SEQUOIA: BRUKINSA demonstrated sustained overall survival (84%; 88% after COVID adjustment) and landmark progression-free survival (PFS) superiority vs bendamustine + rituximab with an estimated 74% PFS at 6 years in treatment-naïve chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL) (Poster Presentation: 2129)

• ALPINE: Post-hoc analysis from Phase 3 study of BRUKINSA versus ibrutinib in patients with relapsed/refractory (R/R) CLL/SLL, using longitudinal patient-reported outcomes (PRO) (Oral Presentation: 711)

• BGB-11417-201: Phase 1/2 study of sonrotoclax in patients with R/R mantle cell lymphoma (MCL) previously treated with a BTK inhibitor (Oral Presentation: 663)

• BGB-11417-101: Updated safety and efficacy results, including undetectable minimal residual disease (uMRD) data, from ongoing Phase 1/1b study of sonrotoclax plus BRUKINSA in treatment-naïve CLL/SLL (Poster Presentation: 3891)

• CaDAnCe-101: Updated efficacy and safety results of BGB-16673 in patients with R/R CLL/SLL and R/R Waldenström macroglobulinemia (WM) (Oral Presentation: 85; Poster Presentation: 3583)

“Our data at ASH 2025 raises the bar for patient and physician expectations of what’s possible. Our long-term data drives confidence in duration of response in CLL treatment decisions,” said Lai Wang, Ph.D., Global Head of R&D at BeOne. “Six-year SEQUOIA and long-term extension data from patients originally enrolled in ALPINE cement BRUKINSA’s role as the backbone of CLL therapy, and our three innovative B-cell treatment modalities of BTK inhibition, BCL2 inhibition, and BTK degradation have the potential to advance options that evolve with patient needs across all stages of disease.”

Additional highlights include:

Never-before-presented clinical data from BeOne’s emerging pipeline will also be shared at the meeting, including in new combinations and disease areas.

• BGB-11417-101: Results from Phase 1/1b study:

  • MRD-guided therapy of sonrotoclax plus obinutuzumab in patients with treatment-naïve CLL/SLL (Oral Presentation: 793)

  • Initial results of treatment with sonrotoclax plus BRUKINSA plus obinutuzumab in patients with treatment-naïve CLL/SLL (Poster Presentation: 3890)

• BGB-11417-202: Phase 2 study of sonrotoclax monotherapy in patients with R/R CLL/SLL (Poster Presentation: 5666)

• BGB-11417-105: Initial results from Phase 1b/2 study of sonrotoclax plus carfilzomib and dexamethasone in patients with t(11;14)-positive R/R multiple myeloma (Oral Presentation: 102)

• CaDAnCe-101 Preliminary results from the ongoing Phase 1 study of BGB-16673 in patients with R/R Richter’s transformation (Poster Presentation: 3895)

Ongoing clinical data from BRUKINSA continue to demonstrate clinically meaningful benefit for patients with CLL/SLL.

• SEQUOIA Arm D: Single-arm study of BRUKINSA plus venetoclax in patients with first-line CLL/SLL, with del(17p) and/or TP53 mutation or without both (Poster Presentation: 5669)

• ALPINE thru LTE1: Up to 6 years of follow-up of patients with R/R CLL/SLL who were originally randomized to receive BRUKINSA as part of the ALPINE study and continued BRUKINSA treatment in a long-term extension study (LTE-1) (Poster Presentation: 2123)

Presentations also include data leveraging real-world evidence and validated modeling approaches to refine understanding of real-world experience and outcomes achieved with covalent BTK inhibitors.

• Outcomes research:

  • A model analysis of number needed to treat (NNT) estimates that treating patients with BRUKINSA instead of ibrutinib for CLL could potentially prevent approximately 255 cardiac deaths in the second-line or later (2L+) setting and 266 in the first-line (1L) setting over a 10-year period. (Abstract Number: 13636)

  • Model evaluating BRUKINSA vs other covalent BTK inhibitors in R/R CLL and the number of patients needed to treat to avoid progression or death (Poster Presentation: 4553)

  • Observational study examining patient-reported outcomes in U.S. patients with CLL/SLL and treated with BRUKINSA or acalabrutinib in the community oncology setting (Poster Presentation: 2768)

“In CLL, selecting the right therapy for the right patient at the right time is essential, and continuous treatment with BTK inhibitors like BRUKINSA has become central to achieving enduring disease control,” said Dany Habr, M.D., Senior Vice President and Head of Medical Affairs, North America & International Markets at BeOne. “Emerging data from real-world settings suggest that BRUKINSA may offer a more manageable side effect profile, including for symptoms such as fatigue, pain, headache – further supporting its role as the BTKi of choice.”

About Sonrotoclax (BGB-11417)

Sonrotoclax is a next-generation and potentially best-in-class investigational B-cell lymphoma 2 (BCL2) inhibitor with a unique pharmacokinetic and pharmacodynamic profile. Studies in the lab and during early drug development have shown that sonrotoclax is a highly potent and specific BCL2 inhibitor with a short half-life and no drug accumulation. Sonrotoclax has shown promising clinical activity across a range of B-cell malignancies and is in development as a monotherapy and in combination with other therapeutics, including BRUKINSA. Notably, in early clinical trials, sonrotoclax plus BRUKINSA has demonstrated rapid and unprecedented undetectable minimal residual disease (uMRD) rates in treatment-naïve patients with CLL. To date, more than 2,200 patients have been enrolled across the broad global development program.

The U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation (BTD) for sonrotoclax for the treatment of adult patients with relapsed or refractory (R/R) mantle cell lymphoma (MCL). In addition, the FDA has granted sonrotoclax Fast Track Designation for MCL and Waldenström macroglobulinemia, as well as Orphan Drug Designation for the treatment of adult patients with MCL, WM, multiple myeloma, acute myeloid leukemia, and myelodysplastic syndrome.

About BGB-16673

BGB-16673 is a potential first-in-class Bruton’s tyrosine kinase (BTK) protein degrader and is the most advanced protein degrader in the clinic, with nearly 800 patients dosed to date in an extensive global clinical development program. This program includes three randomized Phase 3 trials in R/R CLL, including the head-to-head Phase 3 trial versus pirtobrutinib which began enrolling in Q4 2025. Originating from BeOne’s chimeric degradation activation compound (CDAC) platform, BGB-16673 is designed to promote the degradation, or breakdown, of both wildtype and mutant forms of BTK, including those that commonly result in resistance to BTK inhibitors in patients who experience progressive disease.

The U.S. Food and Drug Administration (FDA) granted Fast Track Designation to BGB-16673 for the treatment of adult patients with relapsed or refractory (R/R) chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL), and adult patients with R/R mantle cell lymphoma (MCL). Additionally, the European Medicines Agency (EMA) granted BGB-16673 PRIority MEdicines (PRIME) designation for the treatment of patients with Waldenstrom’s macroglobulinemia (WM) previously treated with a BTK inhibitor.

About BRUKINSA^® (zanubrutinib)

BRUKINSA is an orally available, small molecule inhibitor of Bruton’s tyrosine kinase (BTK) designed to deliver complete and sustained inhibition of the BTK protein by optimizing bioavailability, half-life, and selectivity. With differentiated pharmacokinetics compared with other approved BTK inhibitors, BRUKINSA has been demonstrated to inhibit the proliferation of malignant B cells within a number of disease-relevant tissues.

BRUKINSA has the broadest label globally of any BTK inhibitor and is the only BTK inhibitor to provide the flexibility of once or twice daily dosing. BRUKINSA is also the only BTK inhibitor to demonstrate superiority to another BTK inhibitor in a Phase 3 study.

The global BRUKINSA clinical development program includes about 7,100 patients enrolled in 30 countries and regions across more than 35 trials. BRUKINSA is approved in more than 75 markets, and more than 247,000 patients have been treated globally.

Select Important Safety Information

Serious adverse reactions, including fatal events, have occurred with BRUKINSA, including hemorrhage, infections, cytopenias, second primary malignancies, cardiac arrhythmias, and hepatotoxicity (including drug-induced liver injury).

In the pooled safety population (N=1729), the most common adverse reactions (≥30%), including laboratory abnormalities, in patients who received BRUKINSA were neutrophil count decreased (51%), platelet count decreased (41%), upper respiratory tract infection (38%), hemorrhage (32%), and musculoskeletal pain (31%).
