Zanubrutinib

SAN CARLOS, Calif.--(BUSINESS WIRE)--BeOne Medicines Ltd. (Nasdaq: ONC; HKEX: 06160; SSE: 688235), a global oncology company, reaffirms its position as the leader in chronic lymphocytic leukemia (CLL) innovation by showcasing the depth, quality, and momentum of its hematology portfolio at the 67th ASH Annual Meeting and Exposition in Orlando, Florida. The totality of BeOne’s ASH data reinforce BRUKINSA® (zanubrutinib) as the foundational Bruton’s tyrosine kinase inhibitor (BTKi) of choice. “At ASH 2025, we will present new data from across our CLL franchise, highlighting both the strength of BRUKINSA and the potential of BGB-16673,” said Amit Agarwal, M.D., Ph.D., Chief Medical Officer, Hematology, BeOne. “Long-term data are the gold standard in CLL, and BRUKINSA continues to deliver the high levels of durable progression-free and overall survival that patients and physicians should demand from a BTK inhibitor. BGB-16673, the most advanced BTK degrader in the clinic with over 800 patients dosed to date, potentially represents the next wave of foundational innovation in oncology.” BRUKINSA continues to demonstrate unprecedented long-term efficacy with a favorable safety profile over more than six years of follow-up in treatment-naïve CLL/SLL. In SEQUOIA (NCT03336333), a randomized, multicenter, global Phase 3 trial, BRUKINSA maintained progression-free survival (PFS) superiority versus bendamustine plus rituximab (BR) with an estimated 74% PFS at six years in treatment-naïve CLL or small lymphocytic lymphoma (SLL) compared with 32% PFS for BR. Highlights include: COVID-19 adjusted PFS rates were 77% (95% CI, 70.1-81.8) for BRUKINSA and 33% (95% CI, 25.5-40.4) for BR. The overall survival (OS) at 72 months was 84% for BRUKINSA and 80% with BR. After adjusting for COVID-19, the OS rates were 88% and 82%, respectively. In patients with del(17p), the six-year PFS was 64% (65% after COVID-19 adjustment) and the 72-month OS was 83%. The safety profile of BRUKINSA was consistent with the results of prior studies with no new safety signals identified. “SEQUOIA’s longer follow-up strengthens the evidence for continuous zanubrutinib use,” said Constantine Tam, M.B.B.S., M.D., Head of Lymphoma Service at Alfred Health and Professor of Haematology at Monash University. “Patients continued to show durable disease control and consistent safety across study arms, meaningfully raising the bar for CLL patients, including those with harder-to-treat CLL.” In the overall patient population, in which 58% of patients had del(17p) and/or TP53 mutation, the median PFS was not reached; the 36-month PFS rate was 87%. The 36-month PFS rate for patients with del(17p) and/or TP53 mutation was 87% and for patients without del(17p) and TP53 mutation was 89%. A total of 42 patients completed the BRUKINSA plus venetoclax combination and continued BRUKINSA monotherapy. At 12 months following the combination period, peripheral blood undetectable minimal residual disease (uMRD) was maintained in 100% (18/18) of patients without del(17p) and TP53 . At 18 months following the combination period, uMRD was maintained in 92% (22/24) of patients with del(17p) and/or TP53 mutation. The safety profile of BRUKINSA plus venetoclax was generally tolerable and no unexpected safety signals were identified. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines ® ) now recommend zanubrutinib plus venetoclax as a preferred first-line regimen for CLL/SLL. New patient-reported outcomes data in R/R CLL suggest BRUKINSA may offer a more manageable side effect profile. Up to six-years of follow-up data support BRUKINSA’s foundational role in CLL/SLL as the only BTK inhibitor with enduring PFS and long-term benefit over another BTK inhibitor. ALPINE (NCT03734016) is a global, randomized, open-label, multicenter, Phase 3 study of BRUKINSA versus ibrutinib in patients with R/R CLL/SLL who received ≥1 prior systemic therapy. Highlights include: This study is among the first analyses of patients with CLL/SLL to demonstrate a statistically and clinically meaningful association between longitudinal symptom deterioration and disease progression using joint modeling. Deterioration in patient-reported fatigue, insomnia, and nausea/vomiting emerged as strong symptomatic indicators of disease progression. Compared with ibrutinib, patients on BRUKINSA showed reduced risk of symptom deterioration associated with earlier disease progression. The analysis showed that patients on BRUKINSA had lower odds of symptom worsening for nausea/vomiting, fatigue, pain, and insomnia. With up to 73.5 months of follow-up, the median PFS for all patients was a striking 52.5 months; the 60-month PFS rate was 47.3% (50.4% adjusted for COVID-19). These results redefine what is expected for this patient population. Among patients with del(17p), the median PFS was 49.9 months; the 60-month PFS rate was 38.2% (40.5% adjusted for COVID-19). With longer follow-up, the prevalence of most adverse events of special interest remained stable year-over-year. BGB-16673 (BTK degrader) clinical data demonstrates rapid, robust and deepening responses in patients with heavily pretreated R/R CLL/SLL, including those with prior BTKi treatment and mutations that confer resistance to BTK inhibitors. (Oral Presentation: 85) Updated results from CaDAnCe-101 (NCT05006716), an ongoing open-label, Phase 1/2 study evaluating BGB-16673 monotherapy in patients with B-cell malignancies, showed responses across R/R CLL/SLL patient types, including those who had previously been treated with BTK inhibitors, BCL2 inhibitors, noncovalent BTK inhibitors, and those with BTK inhibitor resistance mutations. Highlights include: With a median follow-up of 19.8 months, 54.4% of patients remain on treatment. Across all doses, ORR was 85.3% and CR/CR with incomplete count recovery (CRi) rate was 2.9% with responses deepening over time. In the group of patients dosed at the recommended phase 2 dose (RP2D; 200 mg QD), ORR was 94.4%. In the patients with prior covalent BTK inhibitor, BCL2i, and noncovalent BTK inhibitor treatment, ORR was 75.0%. In the group of patients dosed at the recommended phase 2 dose (RP2D; 200 mg QD), ORR was 94.4%. In the patients with prior covalent BTK inhibitor, BCL2i, and noncovalent BTK inhibitor treatment, ORR was 75.0%. The 12- and 18-month PFS rates were 73.5% and 65.9% respectively. BGB-16673 was generally well tolerated in this heavily pretreated population with no treatment-related deaths and no new toxicities identified with a median treatment duration of 13.6 months.

About Chronic Lymphocytic Leukemia Chronic lymphocytic leukemia (CLL) is a life-threatening cancer of adults. It is a type of mature B-cell malignancy in which abnormal leukemic B lymphocytes (a type of white blood cells) arise from the bone marrow and flood peripheral blood, bone marrow, and lymphoid tissues.1,2 CLL is the most common type of leukemia in adults, accounting for about one-third of new cases.2,3 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%).

SEATTLE, Dec. 06, 2025 (GLOBE NEWSWIRE) -- Adaptive Biotechnologies Corporation (Nasdaq: ADPT), a commercial stage biotechnology company that aims to translate the genetics of the adaptive immune system into clinical products to diagnose and treat disease, announced growing interventional use of its clonoSEQ® test among the 90 abstracts featuring clonoSEQ data at the 67th American Society of Hematology (ASH) Annual Meeting and Exposition, taking place Dec. 6–9, 2025, in Orlando. Notably, 17 abstracts utilizing Adaptive’s clonoSEQ® test exemplify how next-generation sequencing-based measurable residual disease (MRD) status is guiding clinical actions to improve blood cancer patient care. Practice-changing data from the phase II EndRAD study support the use of NGS MRD status prior to allogeneic hematopoietic cell transplantation (HCT) to guide the selection of non-total body irradiation (TBI) conditioning approaches to reduce long-term toxicities in children and young adults with B-cell acute lymphoblastic leukemia (B-ALL), without compromising outcomes. The study showed outstanding event-free and overall survival outcomes in 51 patients who were NGS MRD negative and received a non-TBI regimen. The study also enrolled a comparator cohort who received TBI and showed equivalent survival in NGS MRD negative patients who received TBI (the current standard of care) compared to non-TBI approaches (oral presentation, abstract 163). “For young people facing leukemia, the impact of treatment doesn’t end when therapy does,” said Michael Pulsipher, M.D., Division Chief of Hematology, Oncology and Bone Marrow Transplantation at Primary Children’s Hospital and Huntsman Cancer Institute at the University of Utah. “The EndRAD results demonstrate that, for NGS MRD-negative patients, we may be able to choose transplant approaches without radiation that support both survival and long-term well-being—an advancement with real, lasting impact for patients and their families.” Across hematologic malignancies, clonoSEQ MRD status is used by health care providers as an interventional tool to guide clinical decisions at key points in care. The presentations below show how investigators are applying clonoSEQ MRD results to tailor treatment intensity or duration with greater precision. Multiple Myeloma (MM) A total of 32 abstracts will be presented (31 MM, one smoldering MM), with a focus on MRD assessment of treatment response, real-world data demonstrating the link between MRD status and clinical outcomes, and several studies describing how clonoSEQ MRD results are being used to guide treatment decisions.A presentation focused on MRD dynamics in the phase III AURIGA study of 200 newly diagnosed MM patients demonstrated that deep MRD responses and sustained MRD negativity correlated with improved progression free survival. The study shows that use of intensified maintenance in MRD-positive patients post-transplant doubled MRD negativity rates (oral presentation, abstract 97). Non-Hodgkin Lymphoma (NHL) Fifteen abstracts in NHL will be presented, focusing on use of MRD to better understand depth of response and to guide therapy.In diffuse large B-cell lymphoma (DLBCL), results from a phase II Wisconsin Oncology Network study which used clonoSEQ to de-escalate therapy in frail older adults with DLBCL will be presented (poster presentation, abstract 1964). Additionally, data supporting the integration of ctDNA into post–CAR T surveillance will be presented (oral presentation, abstract 941).Results from a phase II, MRD-guided study in older mantle cell lymphoma (MCL) patients demonstrate the use of clonoSEQ to guide duration of frontline BOVen therapy (zanubrutinib, obinutuzumab, venetoclax) (oral presentation, abstract 888). Chronic Lymphocytic Leukemia (CLL) Seven abstracts utilizing clonoSEQ MRD will be presented, with the majority leveraging the test to assess treatment response and guide treatment discontinuation.Data from a Phase II study of 80 patients with previously untreated CLL showed that time-limited pirtobrutinib, venetoclax, and obinutuzumab (PVO) achieved notably deep and durable remissions based on MRD assessment at a threshold of 10-6. MRD positive status using clonoSEQ was used to identify patients who may continue therapy, highlighting clonoSEQ as a potential tool for guiding treatment duration in this regimen (oral presentation, abstract 680). Acute Lymphoblastic Leukemia (ALL) In addition to the EndRAD trial, 30 ALL abstracts will be presented describing the use of clonoSEQ to assess treatment response in investigator studies and real-world data, as well as analyses describing comparisons of bone marrow and peripheral blood MRD by clonoSEQ. “The unprecedented volume and diversity of data at ASH this year further solidifies clonoSEQ’s leadership in the field of blood cancer MRD monitoring,” said Susan Bobulsky, chief commercial officer, MRD, Adaptive Biotechnologies. “Our unmatched body of clinical evidence and real-world patient experience, together with meaningful updates across lymphoid cancer clinical practice guidelines over the past year, reflect clear recognition of the test’s value in accelerating therapeutic progress and strengthening MRD-informed patient management.” About clonoSEQ®clonoSEQ® is the first and only FDA-cleared in vitro diagnostic (IVD) test for detecting and tracking minimal (or measurable) residual disease (MRD) in patients with multiple myeloma (MM) or B-cell acute lymphoblastic leukemia (B-ALL) using bone marrow, and in patients with chronic lymphocytic leukemia (CLL) using blood or bone marrow. clonoSEQ is also available in diffuse large B-cell lymphoma (DLBCL), mantle cell lymphoma (MCL) and other lymphoid cancers and specimen types as a CLIA-validated laboratory developed test (LDT). clonoSEQ is covered by Medicare for MM, CLL, ALL, DLBCL and MCL. clonoSEQ identifies and quantifies DNA sequences in malignant cells—detecting one cancer cell in one million healthy cells—to help clinicians and researchers assess and monitor MRD with precision over time. It delivers standardized, sensitive results that inform treatment decisions, predict outcomes, and detect relapses earlier. clonoSEQ is CE-marked under the EU In Vitro Diagnostic Regulation (IVDR). For intended use details in the EU, see the instructions for use, available on request. To review the FDA-cleared uses of clonoSEQ, visit clonoSEQ.com/technical-summary.
