Commercial supply of tislelizumab for China now expanded with wholly owned manufacturing site

BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160), a commercial-stage biotechnology company focused on developing and commercializing innovative medicines worldwide, today announced approval from the China National Medical Products Administration (NMPA) for BeiGene to begin manufacturing commercial supply of its approved anti-PD-1 antibody, tislelizumab, at its state-of-the-art biologics facility in Guangzhou, China. At over one million square feet (100,000 square meters) and 8,000 liters of biologics capacity approved for commercial supply, this wholly owned facility will immediately begin production of commercial supply of tislelizumab for the China market. An additional phase of construction currently in progress to bring total capacity to 64,000 liters is expected to be completed by the end of 2022.

“We started building this large-scale, commercial biologics manufacturing facility in 2017 to meet our expected future demand. Since that time, tislelizumab has been approved in several indications in China, included in the National Reimbursement Drug List (NRDL), and licensed to Novartis in Europe, North America, and Japan,” commented Xiaobin Wu, Ph.D., President, Chief Operating Officer, and General Manager of China at BeiGene. “With significantly expanded capacity for tislelizumab and for other biologics in our pipeline, we are continuing our strong commitment to the quality, safety, and compliance of our products.”

BeiGene’s Guangzhou manufacturing facility has been designed to operate in compliance with current Good Manufacturing Practice (cGMP) standards adopted by the U.S. Food & Drug Administration (FDA), the China National Medical Products Administration (NMPA), and the European Medicines Agency (EMA). The Guangzhou site is expected to be the first paperless biological manufacturing facility in China and integrates new technologies such as 3D modeling, digital twin, augmented interfaces, and artificial intelligence to improve quality and efficiency.

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 granted tislelizumab full approval for first-line treatment of patients with advanced squamous non-small cell lung cancer (NSCLC) in combination with chemotherapy. Tislelizumab has also received conditional approval from the NMPA for the treatment of patients with classical Hodgkin’s lymphoma (cHL) who received at least two prior therapies, and 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. 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 have been accepted by the Center for Drug Evaluation (CDE) of the NMPA and are under review for first-line treatment of patients with advanced non-squamous NSCLC in combination with chemotherapy, for the second- or third-line treatment of patients with locally advanced or metastatic NSCLC who progressed on prior platinum-based chemotherapy, and for previously treated unresectable hepatocellular carcinoma.

Currently, 16 potentially registration-enabling clinical trials are being conducted in China and globally, including 13 Phase 3 trials and three 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.
