BeiGene initiates Phase 3 trial of tislelizumab
BeiGene announced that in December 2017 the first patient was dosed in a global Phase 3 clinical trial of tislelizumab, an investigational anti-PD-1 antibody, in patients with previously untreated advanced hepatocellular carcinoma. Along with two pivotal Phase 2 trials in China in relapsed/refractory classical Hodgkin lymphoma and urothelial cancer, and a global Phase 3 trial in patients with non-small cell lung cancer, tislelizumab is now being evaluated in pivotal trials in four distinct indications. The Phase 3, open-label, multi-center, randomized trial is designed to compare the efficacy and safety of tislelizumab versus sorafenib as a potential first-line treatment in patients with unresectable HCC. Approximately 640 patients will be enrolled at approximately 110 cancer centers in China, the United States, Japan, the United Kingdom, Germany, Spain, Czech Republic, France, and Italy. Patients will be randomized to receive either tislelizumab at 200 mg every three weeks or sorafenib at 400 mg twice daily. The trial's primary endpoint is overall survival, and secondary endpoints include overall response rate, progression free survival, duration of response, time to progression, health-related quality of life, disease control rate, clinical benefit rate, and safety profile.
