Cayman Islands, CAYMAN ISLANDS

CAMBRIDGE, Mass., and BEIJING, China, Nov. 15, 2018 (GLOBE NEWSWIRE) -- BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160), a commercial-stage biopharmaceutical company focused on developing and commercializing innovative molecularly-targeted and immuno-oncology drugs for the treatment of cancer, today announced that Center for Drug Evaluation of China’s National Medical Product Administration (NMPA, formerly known as CFDA) has granted priority review status to the New Drug Applications (NDAs) for the company’s investigational BTK inhibitor zanubrutinib in patients with relapsed/refractory (R/R) mantle cell lymphoma (MCL) and for its investigational anti-PD-1 antibody tislelizumab in patients with R/R classical Hodgkin’s lymphoma (cHL).

“We’re excited that the NDAs for both zanubrutinib and tislelizumab are receiving  priority review by the NMPA,” commented Wendy Yan, Senior Vice President, Global Head of Regulatory Affairs at BeiGene. “We look forward to working closely with the NMPA and CDE in the coming months and hope to bring more treatment options to cancer patients.”  

Zanubrutinib and tislelizumab were both discovered in BeiGene’s research facilities in Beijing, China. Zanubrutinib is being developed globally by BeiGene as a monotherapy and in combination with other therapies to treat various hematologic malignancies. The NDAs for zanubrutinib as a potential treatment for patients with R/R MCL and for patients with R/R chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) were accepted by the NMPA in August and October 2018, respectively. Tislelizumab is being developed as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid and hematologic cancers. The NDA for tislelizumab as a potential treatment for patients with R/R cHL was accepted by the NMPA in August 2018.

Priority review and approval was established in China to facilitate drug registration management and accelerate the development of new drugs with clinical value under the guidance of Opinions on the Reform of the Review & Approval System for Drugs and Medical Devices issued by the State Council in August 2015, and Opinions on Encouraging Pharmaceutical Innovation via Priority Review & Approval issued by CFDA in December 2017. According to these guidelines, the regulatory authority will prioritize the review process and evaluation resources for applications under priority review should expect prioritized review and inspection resource and reduced review and approval timelines.

About Zanubrutinib
Zanubrutinib (BGB-3111) is an investigational small molecule inhibitor of Bruton’s tyrosine kinase (BTK). Zanubrutinib was discovered in BeiGene’s research facilities in Beijing, China, and is being developed globally by BeiGene as a monotherapy and in combination with other therapies to treat various hematologic malignancies.

About Tislelizumab
Tislelizumab (BGB-A317) is an investigational humanized monoclonal antibody that belongs to a class of immuno-oncology agents known as immune checkpoint inhibitors. Discovered by BeiGene scientists in Beijing, tislelizumab is designed to bind to PD-1, a cell surface receptor that plays an important role in downregulating the immune system by preventing the activation of T-cells. Tislelizumab has demonstrated high affinity and specificity for PD-1 in pre-clinical studies. It is potentially differentiated from the currently approved PD-1 antibodies in an engineered Fc region, which is believed to minimize potentially negative interactions with other immune cells, based on preclinical data. Tislelizumab is being developed as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid tumor and hematologic cancers. BeiGene and Celgene Corporation have a global strategic collaboration for the development of tislelizumab in solid tumor cancers outside of Asia (except Japan).
