“We have made great progress in the development of tislelizumab with three global Phase 3 trials now enrolling patients. Along with our partner,
“This potentially registration-enabling trial of tislelizumab is expected to help us further understand its safety and efficacy with respect to the line of treatment in which it is administered to patients with advanced liver cancer. For these patients, as well as for patients in the concurrent front-line Phase 3 study of tislelizumab as compared to sorafenib, we are hopeful that tislelizumab will provide a new treatment option for a patient population with significant unmet needs,” commented
The Phase 2, multi-center trial is designed to evaluate the efficacy and safety of tislelizumab in patients who were previously treated for unresectable HCC. Approximately 225 patients will be enrolled at approximately 75 cancer centers internationally including
The trial’s primary endpoint is overall response rate (ORR) evaluated by an Independent Review Committee (IRC), and secondary endpoints include duration of response (DOR), progression-free survival (PFS), disease control rate (DCR) and clinical benefit rate (CBR) assessed by IRC, and overall survival. Additional secondary endpoints include investigator assessed ORR, DOR, PFS, DCR and CBR, safety and tolerability and health-related quality of life.
“I look forward to evaluating tislelizumab for patients with advanced liver cancer, for whom the expected median survival is typically less than one year. Patients who have either not seen benefit from their front-line or even second-line treatments, or who may have lost an initial response, could potentially respond to tislelizumab. We are excited to build upon the knowledge base we have from the dose expansion cohort of patients with HCC from its Phase 1 trial,” said Professor Ann-Lii Cheng, M.D., Ph.D., Distinguished Professor and Superintendent of the Cancer Center of

About Hepatocellular Carcinoma
HCC is a major global health problem, accounting for 85-90 percent of all reported cases of liver cancer.i Liver cancer is the sixth most common type of cancer, with an estimated 782,000 new cases per year worldwide; it was also the second most common cause of cancer-related mortality, responsible for an estimated 746,000 deaths.ii
Tislelizumab (BGB-A317) 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 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).
