BEIJING, China and CAMBRIDGE, Mass., June 19, 2020 (GLOBE NEWSWIRE) -- BeiGene, Ltd. (NASDAQ:BGNE, HKEX: 06160)), a commercial-stage biotechnology company focused on developing and commercializing innovative molecularly-targeted and immuno-oncology drugs for the treatment of cancer, today announced that the Center for Drug Evaluation (CDE) of the China National Medical Products Administration (NMPA) has accepted a supplemental new drug application (sNDA) of BeiGene's anti-PD-1 antibody tislelizumab in combination with chemotherapy for first-line treatment of patients with advanced non-squamous non-small cell lung cancer (NSCLC).

"We are pleased to submit our second sNDA in first-line advanced NSCLC and the fourth potential indication for tislelizumab in China. We credit the continued momentum of our tislelizumab clinical program to the strong expertise of our teams and the support of clinicians and patients who participated in the trials. We have three additional Phase 3 trials for tislelizumab in lung cancer and we are looking forward to continuing to expand the label for tislelizumab in lung cancer and other indications," commented Xiaobin Wu, Ph.D., General Manager of China and President of BeiGene. "Together with the previously accepted filing in patients with squamous histology, we look forward to continuing our dialogue with the CDE and to hope to bring this innovative treatment to hundreds of thousands of Chinese patients and families impacted by this devastating disease every year."

The sNDA in non-squamous NSCLC is supported by clinical results from a Phase 3 trial of tislelizumab in combination with pemetrexed and platinum chemotherapy of investigator's choice – either carboplatin or cisplatin – in patients with previously untreated stage IIIB or stage IV non-squamous NSCLC and with no EGFR mutations or ALK translocations (NCT03663205). A total of 334 patients were randomized 2:1 to receive tislelizumab in combination with chemotherapy or chemotherapy alone. As announced in April 2020, the trial met its primary endpoint of statistically significant improvement in progression-free survival (PFS), as assessed by independent review committee (IRC) in the pre-planned interim analysis. The safety profile of tislelizumab in combination with pemetrexed and platinum chemotherapy was consistent with the known risks of each study treatment, and no new safety signals were identified. Full results of the trial will be presented at an upcoming meeting.

About Non-Small Cell Lung Cancer

In contrast to most Western countries, where lung cancer death rates are decreasing, lung cancer incidence rates are still increasing in China.1,2 There were approximately 770,000 new cases of lung cancer in China in 2018, and it is the leading cause of cancer-related death in both men and women, with approximately 690,500 deaths in China in 2018.3 Non-small cell lung cancer comprises the most common form of lung cancer in China.4

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.

Tislelizumab is approved by the China National Medical Products Administration (NMPA) as a treatment for patients with classical Hodgkin's lymphoma who received at least two prior therapies and for 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.

In addition, the Center for Drug Evaluation (CDE) of the NMPA has accepted two supplemental new drug applications (sNDAs) for tislelizumab in combination with chemotherapy, one for first-line treatment of patients with advanced squamous non-small cell lung cancer (NSCLC) and the other for first-line treatment of patients with advanced non-squamous NSCLC.

Currently, 16 potentially registration-enabling clinical trials are being conducted in China and globally, including 12 Phase 3 trials and four pivotal Phase 2 trials.

Tislelizumab is not approved for use outside of China.
