CAMBRIDGE, MA, USA and BEIJING, China I January 31, 2018 I BeiGene, Ltd. (NASDAQ:BGNE), 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 patient was dosed in a global Phase 3 clinical trial of tislelizumab, an investigational anti-PD-1 antibody, as a potential second-line treatment in patients with advanced unresectable or metastatic esophageal squamous cell carcinoma (ESCC). Tislelizumab is also being studied in global Phase 3 trials in non-small cell lung cancer and hepatocellular carcinoma and two pivotal Phase 2 trials in China in relapsed/refractory classical Hodgkin lymphoma and urothelial cancer.
“We are pleased to be leading the third global Phase 3 study of tislelizumab under our strategic collaboration with Celgene. These studies are designed to support regulatory filings both in China and globally, and take advantage of our unique global clinical development organization as well as the recent regulatory reforms in China. In 2018, we look forward to further expanding the development program for tislelizumab and to accomplishing key milestones including a planned NDA submission in China,” commented John V. Oyler, Founder, Chief Executive Officer, and Chairman of BeiGene.
“Patients with advanced unresectable or metastatic esophageal carcinomas face poor prognosis, especially those with squamous histology, due to the extremely aggressive nature of the disease. We are hopeful that this Phase 3 trial will establish safety and efficacy of tislelizumab as an important treatment option for these patients,” commented Amy Peterson, M.D., Chief Medical Officer, Immuno-Oncology, at BeiGene.
The Phase 3, open-label, multi-center, randomized trial is designed to compare the efficacy and safety of tislelizumab compared to investigator-chosen chemotherapy as a second-line treatment in patients with advanced unresectable or metastatic ESCC. Approximately 450 patients are planned to be enrolled in Greater China, Japan, Korea, Belgium, France, Germany, Italy, Spain, the United Kingdom and the United States. Patients will be randomized to receive either tislelizumab at 200 mg every three weeks or one of three single-agent chemotherapies, paclitaxel, docetaxel, or irinotecan, as determined by the investigator.
The trial’s primary endpoint is overall survival, and secondary endpoints include progression-free survival, objective response rate, duration of response, health-related quality of life, safety, and tolerability.
“Treatment options for esophageal squamous cell carcinoma have been limited to chemotherapy. Tislelizumab has shown promising anti-tumor activity and has been generally well-tolerated in clinical trials to date in patients with a variety of cancers, including esophageal cancer, and we are hopeful that data from this Phase 3 trial will lead to a new treatment option where it is so greatly needed,” said Professor Lin Shen, M.D., Vice President at the Beijing Cancer Hospital, Beijing, China, and lead investigator of the trial.

About Esophageal Squamous Cell Carcinoma
Esophageal cancer, which includes squamous cell carcinoma, is considered a serious malignancy with respect to prognosis and a fatal outcome in the great majority of cases. Esophageal carcinoma affects more than 450,000 people worldwide.i Esophageal cancer is the eighth most common cancer worldwide and the sixth most common cause of death from cancer.ii
Esophageal squamous cell carcinoma occurs at a rate 20 to 30 times higher in China than in the United States.i An esophageal “cancer belt,” primarily squamous cell cancers, extends from northeast China to the Middle East.i Advanced esophageal cancer is a rapidly fatal disease. More than two-thirds of patients diagnosed with esophageal cancer will have advanced or metastatic disease, with a median survival of 8-10 months and an expected five-year survival rate of less than five percent.iii These data, combined with the relative lack of highly effective treatment, are indicative of the large unmet medical need in patients diagnosed with esophageal cancer.
About Tislelizumab (BGB-A317)
Tislelizumab is an investigational humanized monoclonal antibody that belongs to a class of immuno-oncology agents known as immune checkpoint inhibitors. It 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. It is 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. 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 tislelizumab for solid tumors outside of Asia (except Japan).
