Multiple trials underscore the potential of tislelizumab-containing immuno-oncology combinations in a variety of solid tumor settings Additional highlights include preclinical characterization data for an investigational BTK degrader, BGB-16673, currently in clinical development for B-cell malignancies, including mantle cell lymphoma BASEL, Switzerland & BEIJING & CAMBRIDGE, Mass.--(BUSINESS WIRE)-- BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160; SSE: 688235), a global oncology company, today announced the presentation of emerging oncology pipeline data at the American Association for Cancer Research (AACR) Annual Meeting April 5-10 in San Diego. BeiGene has nine abstracts scheduled for poster presentations at AACR. “Our presentations at this year’s AACR showcase our ongoing development of tislelizumab combinations in solid tumors as we assess the clinical potential of multiple novel immuno-oncology candidates and make data-driven decisions for further development,” said Lai Wang, Ph.D., Global Head of Research & Development at BeiGene. “More broadly, they reflect our deep commitment to discovering innovative new medicines for cancer patients, including by pioneering novel mechanisms like targeted degradation.” BeiGene will present results from the AdvanTIG-204 Phase 2 study of tislelizumab (anti-PD1) plus ociperlimab (anti-TIGIT) in first-line limited-stage small cell lung cancer (SCLC) as well as results of a biomarker study of the same doublet in the setting of first-line non-small cell lung cancer (NSCLC). An ongoing, global Phase 3 trial of ociperlimab plus tislelizumab in stage IV, PD-L1 high NSCLC PD-L1 high NSCLC, AdvanTIG-302, will complete enrollment this month (NCT04746924). An additional clinical presentation includes the first data from a Phase 1a dose escalation study of BGB-10188, a phosphatidylinositol 3 kinase delta (PI3Kδ) inhibitor phosphatidylinositol 3 kinase delta (PI3Kδ) inhibitor, plus tislelizumab in patients with solid tumors. BeiGene will also be presenting preclinical characterizations of several novel molecules from its internal discovery engine, including a CEA x 4-1BB bispecific antibody and a chimeric degradation activation compound (CDAC) targeting BTK, BGB-16673. Clinical data from an ongoing Phase 1 study of BGB-16673 in relapsed/refractory B-cell malignancies were presented at ASH 2023, demonstrating clinical responses and a tolerable safety pro heavily pre-treated patients with B-cell malignancies, including those with BTK inhibitor-resistant disease (NCT05006716). An additional preclinical presentation highlights the therapeutic potential of the triple-combination of tislelizumab with anti-LAG-3 (LBL-007) and anti-TIM-3 (surzebiclimab); this combination is being evaluated in an ongoing Phase 2 study in head and neck squamous cell carcinoma (NCT05909904).
