Results from RATIONALE 309 trial of tislelizumab in combination with chemotherapy in nasopharyngeal cancer will be presented in a proffered paper

Accepted abstracts also include new findings from clinical studies of tislelizumab and sitravatinib

CAMBRIDGE, Mass. & BEIJING, December 02, 2021--(BUSINESS WIRE)--BeiGene (NASDAQ: BGNE; HKEX: 06160), a global, science-driven biotechnology company focused on developing innovative and affordable medicines to improve treatment outcomes and access for patients worldwide, today announced that clinical results and updates from its diverse immuno-oncology portfolio will be presented at the European Society for Medical Oncology Immuno-Oncology (ESMO IO) Congress 2021 being held December 8-11, 2021.

"Despite recent advances in immuno-oncology, chemotherapy remains the standard of care for many patients living with cancer around the world. We look forward to presenting findings on the potential of our anti-PD-1 antibody tislelizumab to treat nasopharyngeal cancer, a rare cancer that is more common in underserved areas of the world, as well as in melanoma and ovarian cancer," commented Yong (Ben) Ben, M.D., Chief Medical Officer, Immuno-Oncology at BeiGene. "Our R&D team, one of the largest oncology R&D teams in the world, is exploring novel combinations and mechanisms of action around the PD-1 axis to identify potential synergies and overcome PD-1 resistance, as we work to increase access to innovative medicines for patients with limited treatment options."

Broad Clinical Program to Address Unmet Needs

To bring forth potential new treatment options and uncover further insights into checkpoint inhibition in solid tumors and hematological malignancies, BeiGene is evaluating tislelizumab, a potentially differentiated anti-PD-1 antibody, in a broad clinical program, including 13 Phase 3 trials and four pivotal Phase 2 trials, and in collaboration with Novartis.

At ESMO IO, results from an interim analysis of the randomized, double-blind, Phase 3 RATIONALE 309 trial (NCT03924986) evaluating tislelizumab in combination with chemotherapy in recurrent or metastatic nasopharyngeal cancer (RM-NPC) will be presented in a Proffered Paper. These results supported the regulatory submission in China for NPC.

Novel Combination Therapies to Expand Clinical Benefit of Anti-PD-1 Antibodies

Combination strategy is considered key to overcoming primary and acquired resistance to anti-PD-1 therapy and expanding clinical benefit of immunotherapy to more patients. BeiGene is investigating the potential of novel tislelizumab combinations to drive stronger and more sustained tumor responses and impede tumor immune escape. At ESMO IO, results from two cohorts of a Phase 1b trial (NCT03666143) evaluating tislelizumab in combination with the oral, spectrum-selective kinase inhibitor sitravatinib in metastatic melanoma and platinum-resistant ovarian cancer will be presented. BeiGene is developing sitravatinib in collaboration with Mirati Therapeutics, Inc.

Additionally, BeiGene will share details on the design of the Phase 3 AdvanTIG-301 trial (NCT04866017) evaluating its investigational Fc-competent anti-TIGIT-antibody ociperlimab in combination with tislelizumab and concurrent chemoradiotherapy (eCRT) as a first-line treatment for patients with locally advanced, unresectable non-small cell lung cancer.
