RATIONALE-301: A Randomized, Open-label, Multicenter Phase 3 Study to Compare the Efficacy and Safety of BGB-A317 Versus Sorafenib as First-Line Treatment in Patients With Unresectable Hepatocellular Carcinoma

BGB-A317-301

This is a Phase 3, randomized, open-label, multicenter, global study designed to compare the efficacy and safety of tislelizumab versus sorafenib as a first-line systemic treatment in participants with unresectable hepatocellular carcinoma. This study also includes a substudy investigating the safety, tolerability, PK, and preliminary efficacy in HCC in Japanese participants. In Japan, preliminary safety and tolerability will be evaluated (Safety Run-In Substudy) before Japanese participants are recruited in this Phase 3 study.
