Submission seeks marketing authorization for first-line use in combination with chemotherapy in advanced esophageal squamous cell carcinoma
CAMBRIDGE, Mass. & BASEL, Switzerland & BEIJING--(BUSINESS WIRE)--
BeiGene (NASDAQ: BGNE; HKEX: 06160; SSE: 688235), a global biotechnology company focused on developing and commercializing innovative and affordable oncology medicines to improve treatment outcomes and access for patients worldwide, today announced that the Center for Drug Evaluation (CDE) of the China National Medical Products Administration (NMPA) has accepted a supplemental biologics license application (sBLA) for tislelizumab in combination with chemotherapy as first-line treatment in patients with unresectable locally advanced, recurrent or metastatic esophageal squamous cell carcinoma (ESCC).
Esophageal cancers are classified based on the type of cells involved and ESCC is the most common subtype, accounting for more than 85% of esophageal cancers worldwidei,ii. In China, esophageal cancer is the fourth leading cause of death due to malignancy and remains a significant threat to public health with 246,000 new diagnoses reported in 2015iii.
“Our global clinical development program for tislelizumab encompasses more than 20 registration-enabling trials and we are pleased that our robust clinical data for tislelizumab are contributing to advancing the treatment landscape for solid tumors in China,” said Lai Wang, Ph.D., Global Head of R&D at BeiGene. “We look forward to working with NMPA on this submission and to progressing global regulatory submissions based on the clinically meaningful overall survival benefit seen in the RATIONALE 306 trial.”
The sBLA is supported by data from an interim analysis of the RATIONALE 306 (NCT03783442) global clinical trial that enrolled 649 patients from research centers across Asia-Pacific, Europe, and North America. RATIONALE 306 results were presented as a late-breaking oral presentation at the 2022 European Society for Medical Oncology (ESMO) World Congress on Gastrointestinal Cancer in June.
Tislelizumab is approved by the China NMPA as a treatment for nine indications, including approval for use in patients with locally advanced or metastatic ESCC who have disease progression or are intolerant to first-line standard chemotherapy. Tislelizumab is not approved for use outside of China.
Tislelizumab is a humanized IgG4 anti-PD-1 monoclonal antibody specifically designed to minimize binding to Fc-gamma (Fcγ) receptors on macrophages, helping to aid the body’s immune cells to detect and fight tumors. In pre-clinical studies, binding to Fcγ receptors on macrophages has been shown to compromise the anti-tumor activity of PD-1 antibodies through activation of antibody-dependent macrophage-mediated killing of T effector cells.
Tislelizumab is the first investigational medicine from BeiGene’s immuno-oncology biologics program and is being evaluated in solid tumor and hematologic malignancies, as monotherapy and in combination.
The global tislelizumab clinical development program includes more than 11,000 subjects enrolled to-date in 30 countries and regions. More information on the tislelizumab development program, including clinical trials and regulatory submissions, can be found on the Tislelizumab Fact Sheet in our corporate press kit.
About RATIONALE 306
RATIONALE 306 (NCT03783442) is a randomized, placebo-controlled, double-blind, global Phase 3 study to evaluate the efficacy and safety of tislelizumab in combination with chemotherapy as a first-line treatment in patients with advanced or metastatic ESCC. The primary endpoint of the trial is overall survival (OS). Secondary endpoints include progression free survival, overall response rate, duration of response per RECIST v1.1, and OS in patients with PD-L1 score ≥ 10%, as well as health-related quality of life measures and safety.
BeiGene is committed to advancing best- and first-in-class clinical candidates internally or with like-minded partners to develop impactful and affordable medicines for patients across the globe. We have a growing R&D and medical affairs team of approximately 3,300 colleagues dedicated to advancing more than 100 clinical trials that have involved more than 16,000 subjects. Our expansive portfolio is directed predominantly by our internal colleagues supporting clinical trials in more than 45 countries and regions. Hematology-oncology and solid tumor targeted therapies and immuno-oncology are key focus areas for the Company, with both mono- and combination therapies prioritized in our research and development. BeiGene currently has three approved medicines discovered and developed in our own labs: BTK inhibitor BRUKINSA® in the U.S., China, the European Union, Great Britain, Canada, Australia, and additional international markets; and the non-FC-gamma receptor binding anti-PD-1 antibody, tislelizumab, as well as the PARP inhibitor, pamiparib, in China.
BeiGene also partners with innovative companies who share our goal of developing therapies to address global health needs. We commercialize a range of oncology medicines in China licensed from Amgen, Bristol Myers Squibb, EUSA Pharma and Bio-Thera. We also plan to address greater areas of unmet need globally through our other collaborations including with Mirati Therapeutics, Seagen, and Zymeworks.
In January 2021, BeiGene and Novartis announced a collaboration granting Novartis rights to co-develop, manufacture, and commercialize BeiGene’s anti-PD1 antibody, tislelizumab, in North America, Europe, and Japan. Building upon this productive collaboration, BeiGene and Novartis announced an option, collaboration, and license agreement in December 2021 for BeiGene’s TIGIT inhibitor, ociperlimab, that is in Phase 3 development. Novartis and BeiGene also entered into a strategic commercial agreement through which BeiGene will promote five approved Novartis Oncology products across designated regions of China.
BeiGene is a global biotechnology company that is developing and commercializing innovative and affordable oncology medicines to improve treatment outcomes and access for far more patients worldwide. With a broad portfolio, we are expediting development of our diverse pipeline of novel therapeutics through our internal capabilities and collaborations.
