BeiGene, Ltd. announced the presentation of emerging oncology pipeline data at the American Association for Cancer Research (AACR) Annual Meeting April 5-10, 2024 in San Diego. 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, AdvanTIG-302, will complete enrollment this month.

An additional clinical presentation includes the first data from a Phase 1a dose escalation study of BGB-10188, a phosphatidylinositol 3 kinase delta (PI3Kd) 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 profile in heavily pre-treated patients with B-cell malignancies, including those with BTK inhibitor-resistant disease.

Tislelizumab 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 receptors on macrophages, helping to aid the body?s immune cells to detect and fight tumors.
