BeiGene Initiates Two Global Phase 3 Front-Line Clinical Trials of Tislelizumab, in Patients with Gastric Cancer and in Patients with Esophageal Cancer
CAMBRIDGE, Mass., and BEIJING, China, Dec. 17, 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 the first patients have been enrolled in two global Phase 3 clinical trials of its investigational anti-PD-1 antibody, tislelizumab. These trials are evaluating tislelizumab combined with chemotherapy as potential first-line treatments in patients with locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma, and in patients with unresectable, locally advanced recurrent or metastatic esophageal squamous cell carcinoma (ESCC).
“Available data have shown promise for anti-PD-1 antibodies in patients with advanced gastric or gastroesophageal adenocarcinoma and in patients with advanced esophageal carcinoma. We are looking forward to investigating tislelizumab globally in these Phase 3 trials,” said Amy Peterson, M.D., Chief Medical Officer, Immuno-Oncology, at BeiGene. “Gastric and esophageal cancers are among the most common malignancies in Asia and collectively are responsible for over 800,000 deaths annually in China1 alone. We are hopeful that these global studies of tislelizumab may ultimately lead to improved treatment options for patients diagnosed with these malignancies.”
Global Phase 3 Trial in Advanced Gastric or Gastroesophageal Adenocarcinoma
The global, randomized, double-blind, placebo-controlled Phase 3 trial is designed to enroll 720 patients with locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma. Patients will either receive 200 mg of tislelizumab or placebo combined with platinum- and fluoropyrimidine-based chemotherapy, the standard chemotherapy treatment, intravenously once every three weeks.
The co-primary endpoints will be progression-free survival (PFS) and overall survival (OS). Secondary endpoints include overall response rate (ORR), duration of response (DOR) and quality of life (QoL), as well as safety and tolerability.
Global Phase 3 Trial in Advanced ESCC
The global, randomized, double-blind, placebo-controlled Phase 3 trial is designed to enroll 480 patients with unresectable, locally advanced recurrent, or metastatic ESCC. Patients will either receive 200 mg of tislelizumab or placebo combined with platinum- and fluoropyrimidine-based chemotherapy, intravenously once every three weeks.
The co-primary endpoints will be PFS and OS. Secondary endpoints include ORR, DOR, and QoL, as well as safety and tolerability.

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.
Discovered by BeiGene scientists, 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. The new drug application (NDA) for tislelizumab in China for patients with R/R cHL has been accepted by the China National Medical Products Administration (NMPA, formerly known as CFDA) and granted priority review status. BeiGene and Celgene Corporation have a global strategic collaboration for the development of tislelizumab in solid tumors in the United States, Europe, Japan, and the rest of world outside Asia.
BeiGene is a global, commercial-stage, research-based biotechnology company focused on molecularly-targeted and immuno-oncology cancer therapeutics. With a team of over 1,700 employees in China, the United States, Australia and Switzerland, BeiGene is advancing a pipeline consisting of novel oral small molecules and monoclonal antibodies for cancer. BeiGene is also working to create combination solutions aimed to have both a meaningful and lasting impact on cancer patients. BeiGene markets ABRAXANE® (nanoparticle albumin–bound paclitaxel), REVLIMID® (lenalidomide), and VIDAZA® (azacitidine) in China under a license from Celgene Corporation.2
