BeOne Medicines Sets the Pace in Oncology at ASCO and EHA 2026 with 60+ Abstracts

SAN CARLOS, CALIF.--(Business Wire / Korea Newswire)--BeOne Medicines Ltd. (Nasdaq: ONC; HKEX: 06160; SSE: 688235), a global oncology company, today announced that more than 60 abstracts across hematologic malignancies and solid tumors have been accepted for presentation at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting (May 29-June 2, Chicago) and the 2026 European Hematology Association (EHA) Congress (June 11-14, Stockholm).

Continuing to raise the bar in CLL

At ASCO and EHA 2026, BeOne will showcase its hematology leadership with data spanning foundational therapies and next-generation innovation across CLL, mantle cell lymphoma and other B-cell malignancies. The data emphasize impressive long-term outcomes, durability across patient populations, and a disciplined approach to advancing future regimens. Collectively, these data underscore BeOne’s strategy to lead in hematology science and patient impact by setting the standard today - while helping to shape the future of CLL.

Amit Agarwal, M.D., Ph.D., Chief Medical Officer, Hematology, BeOne Medicines, said:

“Seventy-eight-month follow-up data from SEQUOIA underscore what it truly takes to lead in CLL over the long term: long-term efficacy, ability for sequencing treatments, and confidence in first-line treatment decisions. Building on that leadership, we’re excited to be rapidly advancing the next generation of medicines, including sonrotoclax-based combinations and our BTK degrader BGB-16673, which are designed to extend what is possible for patients across lines of therapy.”

Key data presentations in CLL include:

· New results from the SEQUOIA trial with 78 months follow-up reinforce BRUKINSA® (zanubrutinib) as the foundational BTK inhibitor in CLL, with durable disease control that continues to raise expectations for what patients and physicians should expect from first-line therapy over the long term. Data will be presented at both ASCO and EHA.
· A subgroup analysis of SEQUOIA, which includes one of the largest and longest-followed cohorts of patients aged ≥80 years ever reported in a Phase 3 CLL study, showing that age did not limit benefit. Data will be presented at EHA 2026.
· Oral presentation at EHA 2026 of updated data of BeOne’s foundational BTK degrader - BGB-16673 - in patients with R/R CLL, demonstrating promising and durable activity and a manageable safety profile. An additional poster will be shared featuring never-before-presented data of BGB-16673 in BTK-naïve patients. BGB-16673 is the most advanced BTK degrader in the clinic, with more than 1,100 patients dosed.
· Data from the all-oral combination of BeOne’s foundational BCL2 inhibitor sonrotoclax plus zanubrutinib (ZS) in CLL, which demonstrated deep responses, unprecedented speed to undetectable MRD, and durable remissions and a generally well-tolerated safety profile. These data reinforce the potential for a next-generation, time-limited approach designed to deliver long-term outcomes without compromising durability or safety. Data will be presented as a poster at ASCO 2026 and an oral presentation at EHA 2026.

Accelerating a high-potential solid tumor portfolio

BeOne is highlighting strong momentum across its deep and diverse solid tumor portfolio at ASCO, with seven unique assets featured in three oral presentations and eight posters. These data span both in-line and pipeline therapies, including results demonstrating the differentiated profile of PD-1 inhibitor TEVIMBRA® (tislelizumab) across lung and gastrointestinal cancers, as well as in combination with the novel HER2-targeting agent ZIIHERA® (zanidatamab). The Company’s development superhighway is accelerating progress across all stages of development, generating compelling clinical data that support the potential of these therapies to reshape treatment in areas of high unmet need.

Mark Lanasa, M.D., Ph.D., Chief Medical Officer, Solid Tumors, BeOne Medicines, said:

“At ASCO 2026, we are demonstrating the strength of BeOne’s science, the scale of our pipeline, and the speed at which we are delivering innovation for patients. With multiple programs moving simultaneously toward pivotal trials, we are building durable disease leadership across breast, gynecologic, lung and gastrointestinal cancers - areas where substantial unmet patient need remains.”

Key data presentations across our solid tumor programs include:

· First disclosure of anti-tumor effects and safety/tolerability profile of the highly selective CDK4 inhibitor BGB-43395 Phase 1 treatment data in first-line HR-positive/HER2-negative breast cancer.
· Rapid oral presentation on BG-C9074, a promising B7-H4-targeting ADC, with Phase 1 dose escalation and safety expansion data.
· Rapid oral presentation on BGB-B2033, a potentially first-in-class GPC3 x 4-1BB bispecific antibody, with first clinical data of a Phase 1 study in heavily pre-treated hepatocellular carcinoma patients.
· Rapid oral presentation with a PD-L1 subgroup analysis of the HERIZON-GEA-01 trial in which TEVIMBRA in combination with ZIIHERA and chemotherapy demonstrated a statistically significant improvement in overall survival (OS) and progression-free survival (PFS) in patients with HER2+ gastroesophageal adenocarcinoma, irrespective of PD-L1 expression (in partnership with Jazz Pharmaceuticals).

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.

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

The global BRUKINSA clinical development program includes more than 8,000 patients enrolled in over 30 countries and regions across more than 45 trials. BRUKINSA is approved in 80 markets in at least one indication, and more than 290,000 patients have been treated globally.

About BEQALZI™ (sonrotoclax)

BEQALZI™ (sonrotoclax) is a foundational, next-generation and potentially best-in-class B-cell lymphoma 2 (BCL2) inhibitor with a unique pharmacokinetic and pharmacodynamic profile. Preclinical and clinical studies in early drug development have shown that sonrotoclax is a highly potent and specific BCL2 inhibitor with a short half-life and no drug accumulation. BEQALZI has shown promising clinical activity across a range of B-cell malignancies, including chronic lymphocytic leukemia (CLL), and is in development as a monotherapy and in combination with other therapeutics, including zanubrutinib. To date, more than 2,200 patients have been enrolled across the broad sonrotoclax global development program.

About BGB-16673

BGB-16673 is a foundational and potential first-in-class and best-in-class Bruton’s tyrosine kinase (BTK) degrader for the treatment of B-cell malignancies. With 1,100+ patients dosed to date in an extensive global clinical development program, BGB-16673 is the most advanced BTK degrader in the clinic. 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 ZIIHERA (zanidatamab)

ZIIHERA (zanidatamab) is a bispecific human epidermal growth factor receptor 2, or HER2-directed antibody that binds to two extracellular sites on HER2. Binding of zanidatamab with HER2 results in internalization leading to a reduction in HER2 expression of the receptor on the tumor cell surface. Zanidatamab induces complement-dependent cytotoxicity (CDC), antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP). These mechanisms result in tumor growth inhibition and cell death in vitro and in vivo.[1]

Zanidatamab is being developed in multiple clinical trials as a targeted treatment option for patients with solid tumors that express HER2. Zanidatamab is approved in China for the treatment of patients who have unresectable, locally advanced, or metastatic HER2-high expression (IHC 3+) biliary tract cancer (BTC) and who have received prior systemic therapy. ZIIHERA has also been granted accelerated approval in the U.S. and conditional marketing authorization in the European Union for eligible BTC patients. Zanidatamab is being developed by Jazz and BeOne under license agreements from Zymeworks, which first developed the molecule. BeOne has licensed zanidatamab from Zymeworks in Asia (excluding India and Japan), Australia and New Zealand. Jazz Pharmaceuticals has rights in all other regions.

ZIIHERA is a registered trademark of Zymeworks BC Inc.

About TEVIMBRA (tislelizumab)

TEVIMBRA is a uniquely designed humanized immunoglobulin G4 (IgG4) anti-programmed cell death protein 1 (PD-1) monoclonal antibody with high affinity and binding specificity against PD-1. It is designed to minimize binding to Fc-gamma (Fcγ) receptors on macrophages, helping to aid the body’s immune cells to detect and fight tumors.

TEVIMBRA is the foundational asset of BeOne’s solid tumor portfolio and has shown potential across multiple tumor types and disease settings. The global TEVIMBRA clinical development program includes almost 15,000 patients enrolled to date in 30+ countries and regions across 71 trials, including 21 registration-enabling studies. TEVIMBRA is approved in over 50 countries, and more than 2 million patients have been treated globally.
