"This latest approval for tislelizumab demonstrates BeiGene’s commitment to bringing innovative, impactful treatments to patients in need. With six approved indications in China, tislelizumab has the potential to reach and help the country’s large patient community, and our science-based commercial team of nearly 3,000 people in China is working to make it more broadly available to those who may benefit from this important immunotherapy," commented Xiaobin Wu, Ph.D., President, Chief Operating Officer, and General Manager of China at BeiGene. "As our strategic oncology collaboration with Novartis deepens, we look forward to continued opportunities to expand access to tislelizumab globally and further explore its therapeutic potential."
"As its third approved lung cancer indication in China, today’s approval represents an important milestone, with tislelizumab now available in both front-line and second- or third-line care of NSCLC. We hope, as demonstrated in the promising results from the global RATIONALE 303 trial, that tislelizumab will become an important treatment option for these patients in China," commented Yong (Ben) Ben, M.D., Chief Medical Officer, Solid Tumors at BeiGene. "Tislelizumab’s broad global development program of 13 Phase 3 trials and four pivotal Phase 2 trials is providing a growing body of clinical evidence on its efficacy and safety and establishing its therapeutic impact across multiple cancer types."
"In the global Phase 3 trial, tislelizumab demonstrated a significant improvement in overall survival and was well-tolerated in patients with previously treated NSCLC," said Caicun Zhou, M.D., Ph.D., Director of the Department of Oncology at Shanghai Pulmonary Hospital, Director of Cancer Institute of Tongji University, and the principal investigator of the trial. "The NMPA’s approval of tislelizumab is welcoming news to the lung cancer community in China, and we hope this immunotherapy will help address the unmet needs in second- or third-line treatment of NSCLC."
The approval of tislelizumab was supported by clinical results from a randomized, open-label, global Phase 3 trial RATIONALE 303 (NCT03358875) comparing tislelizumab to docetaxel in the second- or third-line setting in patients with locally advanced or metastatic NSCLC who have progressed on prior platinum-based chemotherapy. A total of 805 patients in 10 countries across Asia, Europe, the Americas, and Oceania were enrolled in the trial, randomized 2:1 to either the tislelizumab arm or the docetaxel arm.
As announced in November 2020, the trial met the primary endpoint of overall survival (OS) at the planned interim analysis, as recommended by the independent Data Monitoring Committee (IDMC). Tislelizumab was generally well-tolerated, consistent with known safety risks from previously reported results across different tumor types, with no new safety signals identified. The results of the interim analysis of the trial were presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting and announced by BeiGene in April 2021.
About Non-Small Cell Lung Cancer
Lung cancer remains the second most common type of cancer and the leading cause of cancer-related death worldwide.1 NSCLC accounts for approximately 85% of all lung cancer cases and is usually diagnosed at an advanced stage.2 The five-year survival rate with treatment for stage IIIB and stage IV NSCLC is 5% and 2%, respectively.3 In China, the lung cancer incidence rate is increasing, with approximately 815,563 new cases in 2020.4,5
About Tislelizumab
Tislelizumab (BGB-A317) is a humanized IgG4 anti-PD-1 monoclonal antibody specifically designed to minimize binding to FcγR on macrophages. In pre-clinical studies, binding to FcγR 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 drug from BeiGene’s immuno-oncology biologics program and is being developed internationally as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid tumor and hematologic cancers.
The China National Medical Products Administration (NMPA) has approved tislelizumab in six indications, including full approval for first-line treatment of patients with advanced squamous non-small cell lung cancer (NSCLC) in combination with chemotherapy, for first-line treatment of patients with advanced non-squamous NSCLC in combination with chemotherapy, and for second- or third-line treatment of patients with locally advanced or metastatic NSCLC who progressed on prior platinum-based chemotherapy. NMPA also granted conditional approval for the treatment of patients with classical Hodgkin’s lymphoma (cHL) who received at least two prior therapies, for the treatment of patients with locally advanced or metastatic urothelial carcinoma (UC) with PD-L1 high expression whose disease progressed during or following platinum-containing chemotherapy or within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy, and for the treatment of patients with hepatocellular carcinoma (HCC) who have received at least one systemic therapy. Full approval for these indications is contingent upon results from ongoing randomized, controlled confirmatory clinical trials.
In addition, three supplemental Biologics License Applications for tislelizumab are under review by the Center for Drug Evaluation (CDE) of the NMPA, including for patients with previously treated, locally advanced unresectable or metastatic microsatellite instability-high (MSI-H) or mismatch repair-deficient (dMMR) solid tumors, for the treatment of patients with locally advanced or metastatic esophageal squamous cell carcinoma (ESCC) who have disease progression following or are intolerant to first-line standard chemotherapy, and for first-line treatment of patients with recurrent or metastatic nasopharyngeal cancer (NPC).
In the U.S., a Biologics License Application for tislelizumab as a treatment for patients with unresectable recurrent locally advanced or metastatic ESCC after prior systemic therapy is currently under review by the U.S. Food and Drug Administration with a PDUFA target action date of July 12, 2022.
BeiGene has initiated or completed 17 potentially registration-enabling clinical trials in China and globally, including 13 Phase 3 trials and four pivotal Phase 2 trials.
In January 2021, BeiGene and Novartis entered into a collaboration and license agreement granting Novartis rights to develop, manufacture, and commercialize tislelizumab in North America, Europe, and Japan.
Tislelizumab is not approved for use outside of China.

In January 2021 BeiGene and Novartis announced a collaboration granting Novartis rights to develop, manufacture, and commercialize BeiGene’s anti-PD1 antibody tislelizumab in North America, Europe, and Japan. Since closing the collaboration in February 2021, the companies have accomplished key objectives in their collaboration, including filing the first biologics license application (BLA) for tislelizumab outside of China. The U.S. Food and Drug Administration (FDA) accepted for review the BLA submission for patients with unresectable recurrent locally advanced or metastatic esophageal squamous cell carcinoma (ESCC) after prior systemic therapy. The Prescription Drug User Fee Act (PDUFA) target action date is July 12, 2022, and the companies are working closely together on launch preparation activities as well as other planned BLA submissions and combination strategies for tislelizumab within each company’s product portfolio and pipeline. Building upon that progress and the shared commitment to expanding patient access to new treatments, the companies have entered into a new agreement to collaborate on the development, manufacturing and commercialization of BeiGene’s investigational TIGIT inhibitor ociperlimab.
