SAN CARLOS, Calif.--(BUSINESS WIRE)--BeiGene, Ltd. (NASDAQ: ONC; HKEX: 06160; SSE: 688235), a global oncology company that will change its name to BeOne Medicines Ltd., today announced it will share data across a range of hematologic malignancies at the European Hematology Association (EHA) Congress in Milan, Italy, June 12–15. BeiGene has 31 abstracts accepted at EHA 2025, with four selected for oral presentations, featuring data from its best-in-class Bruton’s tyrosine kinase (BTK) inhibitor BRUKINSA® (zanubrutinib) and its investigational pipeline assets – a next-generation BCL2 inhibitor, sonrotoclax, and BTK protein degrader, BGB-16673. These data reflect BeiGene’s vision to redefine standards of care in hematology through next-generation science and patient-focused innovation. “With three cornerstone hematology assets – BRUKINSA, sonrotoclax and BGB-16673 – we are advancing a potentially best-in-class portfolio in B-cell malignancies,” said Lai Wang, Ph.D. Global Head of R&D. “At EHA 2025, we’ll share 31 accepted abstracts that highlight the progress of our hematology clinical development program and our commitment to targeted therapies that raise the standard of care. As BRUKINSA continues to expand its impact and our next-generation assets advance, we hope to transform the future of treatment for patients facing B-cell malignancies.” BeiGene’s next-generation pipeline assets, including BGB-16673 and sonrotoclax, continue to demonstrate promising clinical activity and generally well-tolerated safety profiles across multiple B-cell malignancies. Together, these programs have enrolled more than 2,500 patients globally (1,900+ patients for sonrotoclax and 600+ patients for BGB-16673) and are positioned to potentially play a significant role in treatment strategies for chronic lymphocytic leukemia (CLL), Waldenström’s macroglobulinemia (WM) and mantle cell lymphoma (MCL). Additionally, presentations further reinforce BRUKINSA’s durable efficacy and consistent safety profile, as well as its position as a foundational therapeutic option in frontline CLL. Key highlights include: Two oral presentations featuring updated results from the ongoing Phase 1 CaDAnCe-101 study of BGB-16673 in patients with relapsed or refractory (R/R) CLL/SLL and patients with R/R WM, showing continued and promising early efficacy and a tolerable safety profile. Two oral presentations showcasing updated Phase 1 results of sonrotoclax in combination with BRUKINSA in R/R CLL/SLL and R/R MCL, which demonstrate deep and durable responses. This combination is now under evaluation in the ongoing registrational Phase 3 fixed-duration CELESTIAL-TNCLL study ( NCT06073821 ) in patients with treatment-naïve CLL/SLL, which completed enrollment earlier this year, and CELESTIAL-RRMCL study ( NCT06742996 ) in patients with relapsed / refractory MCL, which is currently enrolling. Results from Arm C and D of the SEQUOIA study, which evaluated BRUKINSA in patients with TN CLL/SLL and del(17p) (Arm C) and BRUKINSA plus venetoclax in patients with TN CLL/SLL with del(17p) and/or TP53 mutation or without either mutation (Arm D). Robust analyses across clinical trials and real-world evidence that deepen understanding of treatment patterns, safety, and outcomes in CLL/SLL, MCL and diffuse large B-cell lymphoma (DLBCL).

Cai About Sonrotoclax (BGB-11417) Sonrotoclax is designed to block the B-cell lymphoma 2 (BCL2) protein, which is one of several proteins that help cancer cells survive. It is part of a group of drugs called BH3 mimetics, which mimic natural cell death signals. Studies in the lab and during early drug development have shown that sonrotoclax is a potent and specific inhibitor of BCL2 with a short half-life and no accumulation. Sonrotoclax has shown promising clinical activity across a range of B-cell malignancies, and more than 1,900 patients have been enrolled to date across the global development program. The U.S. Food and Drug Administration (FDA) granted sonrotoclax Fast Track Designation for the treatment of adult patients with mantle cell lymphoma (MCL) and Waldenström macroglobulinemia (WM). About BGB‑16673 BGB-16673 is an orally available Bruton’s tyrosine kinase (BTK) targeting protein degrader from BeiGene’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. BGB-16673 is the most advanced BTK protein degrader in the clinic, with an extensive global clinical development program. 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). 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 200,000 patients have been treated globally. U.S. Indications and Important Safety Information for BRUKINSA (zanubrutinib) INDICATIONS BRUKINSA is a kinase inhibitor indicated for the treatment of adult patients with: Chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). Waldenström’s macroglobulinemia (WM). Mantle cell lymphoma (MCL) who have received at least one prior therapy. Relapsed or refractory marginal zone lymphoma (MZL) who have received at least one anti-CD20-based regimen. Relapsed or refractory follicular lymphoma (FL), in combination with obinutuzumab, after two or more lines of systemic therapy. The MCL, MZL and FL indications are approved under accelerated approval based on overall response rate and durability of response. Continued approval for these indications may be contingent upon verification and description of clinical benefit in confirmatory trials. IMPORTANT SAFETY INFORMATION Warnings and Precautions Hemorrhage Fatal and serious hemorrhage has occurred in patients with hematological malignancies treated with BRUKINSA. Grade 3 or higher hemorrhage including intracranial and gastrointestinal hemorrhage, hematuria, and hemothorax was reported in 3.8% of patients treated with BRUKINSA in clinical trials, with fatalities occurring in 0.2% of patients. Bleeding of any grade, excluding purpura and petechiae, occurred in 32% of patients. Bleeding has occurred in patients with and without concomitant antiplatelet or anticoagulation therapy. Coadministration of BRUKINSA with antiplatelet or anticoagulant medications may further increase the risk of hemorrhage. Monitor for signs and symptoms of bleeding. Discontinue BRUKINSA if intracranial hemorrhage of any grade occurs. Consider the benefit-risk of withholding BRUKINSA for 3-7 days before and after surgery depending upon the type of surgery and the risk of bleeding. Infections Fatal and serious infections (including bacterial, viral, or fungal infections) and opportunistic infections have occurred in patients with hematological malignancies treated with BRUKINSA. Grade 3 or higher infections occurred in 26% of patients, most commonly pneumonia (7.9%), with fatal infections occurring in 3.2% of patients. Infections due to hepatitis B virus (HBV) reactivation have occurred. Consider prophylaxis for herpes simplex virus, pneumocystis jirovecii pneumonia, and other infections according to standard of care in patients who are at increased risk for infections. Monitor and evaluate patients for fever or other signs and symptoms of infection and treat appropriately. Cytopenias Grade 3 or 4 cytopenias, including neutropenia (21%), thrombocytopenia (8%) and anemia (8%) based on laboratory measurements, developed in patients treated with BRUKINSA. Grade 4 neutropenia occurred in 10% of patients, and Grade 4 thrombocytopenia occurred in 2.5% of patients. Monitor complete blood counts regularly during treatment and interrupt treatment, reduce the dose, or discontinue treatment as warranted. Treat using growth factor or transfusions, as needed. Second Primary Malignancies Second primary malignancies, including non-skin carcinoma, have occurred in 14% of patients treated with BRUKINSA. The most frequent second primary malignancy was non-melanoma skin cancers (8%), followed by other solid tumors in 7% of the patients (including melanoma in 1% of patients) and hematologic malignancies (0.7%). Advise patients to use sun protection and monitor patients for the development of second primary malignancies. Cardiac Arrhythmias Serious cardiac arrhythmias have occurred in patients treated with BRUKINSA. Atrial fibrillation and atrial flutter were reported in 4.4% patients treated with BRUKINSA, including Grade 3 or higher cases in 1.9% of patients. Patients with cardiac risk factors, hypertension, and acute infections may be at increased risk. Grade 3 or higher ventricular arrhythmias were reported in 0.3% of patients. Monitor for signs and symptoms of cardiac arrhythmias (e.g., palpitations, dizziness, syncope, dyspnea, chest discomfort), manage appropriately, and consider the risks and benefits of continued BRUKINSA treatment. Hepatotoxicity, Including Drug-Induced Liver Injury Hepatotoxicity, including severe, life-threatening, and potentially fatal cases of drug-induced liver injury (DILI), has occurred in patients treated with Bruton tyrosine kinase inhibitors, including BRUKINSA. Evaluate bilirubin and transaminases at baseline and throughout treatment with BRUKINSA. For patients who develop abnormal liver tests after BRUKINSA, monitor more frequently for liver test abnormalities and clinical signs and symptoms of hepatic toxicity. If DILI is suspected, withhold BRUKINSA. Upon confirmation of DILI, discontinue BRUKINSA. Embryo-Fetal Toxicity Based on findings in animals, BRUKINSA can cause fetal harm when administered to a pregnant woman. Administration of zanubrutinib to pregnant rats during the period of organogenesis caused embryo-fetal toxicity, including malformations at exposures that were 5 times higher than those reported in patients at the recommended dose of 160 mg twice daily. Advise women to avoid becoming pregnant while taking BRUKINSA and for 1 week after the last dose. Advise men to avoid fathering a child during treatment and for 1 week after the last dose. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus. Adverse Reactions The most common adverse reactions (≥30%), including laboratory abnormalities, in patients who received BRUKINSA (N=1729) are decreased neutrophil count (51%), decreased platelet count (41%), upper respiratory tract infection (38%), hemorrhage (32%), and musculoskeletal pain (31%). Drug Interactions CYP3A Inhibitors: When BRUKINSA is co-administered with a strong CYP3A inhibitor, reduce BRUKINSA dose to 80 mg once daily. For coadministration with a moderate CYP3A inhibitor, reduce BRUKINSA dose to 80 mg twice daily. CYP3A Inducers: Avoid coadministration with strong or moderate CYP3A inducers. Dose adjustment may be recommended with moderate CYP3A inducers. Specific Populations Hepatic Impairment: The recommended dose of BRUKINSA for patients with severe hepatic impairment is 80 mg orally twice daily.
