BEIJING, China?and?CAMBRIDGE, Mass.,?July 07, 2019?(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 the?China National Medical Products Administration?(NMPA, formerly known as the CFDA) has granted priority review status to the supplemental new drug application (sNDA) for tislelizumab, an investigational Fc-engineered anti-PD-1 antibody, for patients with previously treated locally-advanced or metastatic urothelial carcinoma (UC).

?This is our second priority review granted by the NMPA for tislelizumab, and our first for a solid tumor indication and first in?China?for a PD-1/PDL1 antibody for bladder cancer,? said?Wendy Yan, Senior Vice President, Global Head of Regulatory Affairs, at?BeiGene. ?Along with the two priority reviews granted for zanubrutinib in?China, our regulatory team is working closely with the NMPA as it reviews our applications to treat patients with solid tumors and hematologic cancers. With full global rights to tislelizumab, 13 ongoing pivotal or potentially registration-enabling trials, maturing international clinical and non-clinical data, and advanced manufacturing capabilities, we are excited by the prospects for tislelizumab to help patients in-need around the world.?

The sNDA for tislelizumab as a potential treatment for patients with previously treated locally-advanced or metastatic UC was accepted by the NMPA in?May 2019. It is supported by a clinical, non-clinical, and Chemistry, Manufacturing and Controls (CMC) data package, including the results from a pivotal Phase 2 study of tislelizumab in 113 Chinese and South Korean patients with previously treated PD-L1+ locally-advanced or metastatic UC (chinadrugtrials.org registration number: CTR20170071).?BeiGene?is developing tislelizumab as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid and hematologic cancers. An NDA for tislelizumab as a potential treatment for patients with relapsed / refractory (R/R) classic Hodgkin?s lymphoma (cHL) was accepted by the NMPA in?August 2018and granted priority review status in?November 2018.

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

About Urothelial Carcinoma

Urothelial carcinoma (UC), also known as transitional cell carcinoma (TCC), is by far the most common type of bladder cancer.ⁱ?In 2018, there was an estimated 82,270 incidences of bladder cancer in?China, accounting for 15.0 percent of all incidences worldwide.ⁱⁱ?Although UC is most common in the bladder, it can occur in other parts of the urinary system.

About Tislelizumab

Tislelizumab (BGB-A317) is an investigational humanized IgG4 anti?PD-1 monoclonal antibody specifically designed to minimize binding to Fc?R on macrophages. In pre-clinical studies, binding to Fc?R 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 candidate produced from BeiGene?s immuno-oncology biologic program and 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.

Ongoing clinical trials of tislelizumab include a Phase 3 clinical trial in patients with second-line or third-line non-small cell lung cancer (NSCLC); a Phase 3 clinical trial in first-line patients with hepatocellular carcinoma (HCC); a Phase 3 clinical trial in second-line patients with esophageal squamous carcinoma (ESCC); a Phase 3 clinical trial in first-line patients with gastric cancer (GC); a Phase 3 clinical trial in first-line patients with ESCC; a Phase 2 clinical trial in second- or third-line patients with HCC; and a Phase 1 clinical trial in patients with R/R NK/T-cell lymphomas. The aforementioned trials are enrolling patients in multiple countries, including?the United States,?Europe, and?China.

In addition to a pivotal Phase 2 clinical trial in patients with relapsed or refractory (R/R) classical Hodgkin?s lymphoma (cHL) and a pivotal Phase 2 clinical trial in patients with locally advanced or metastatic urothelial cancer,?BeiGene?is conducting a Phase 3 clinical trial in first-line patients with non-squamous NSCLC; a Phase 3 clinical trial in first-line patients with squamous NSCLC; a Phase 3 clinical trial in patients with first-line nasopharyngeal cancer (NPC); a Phase 3 clinical trial in first-line patients with urothelial carcinoma (UC); a Phase 3 clinical trial in patients with localized ESCC; and a Phase 2 trial in patients with MSI-H or dMMR solid tumors. These studies have been enrolling patients primarily in?China.

New drug applications (NDA) for tislelizumab in patients with R/R cHL and in patients with previously treated locally advanced or metastatic UC have been accepted and granted priority review by the?China National Medical Products Administration?(NMPA, formerly known as CFDA).?BeiGene?has full development and commercial rights to tislelizumab worldwide.
