简要总结
This study will evaluate the efficacy and safety of atezolizumab plus bevacizumab combined with on-demand TACE compared to on-demand TACE alone in participants with hepatocellular carcinoma who are at high risk of poorer outcome following TACE treatment.

结局指标
主要结局
TACE Progression-Free Survival (TACE PFS) as Determined by Investigator
时间窗: Randomization to untreatable progression or TACE failure/refractoriness or death (up to approximately 46 months)
TACE PFS is defined as the time from randomization to untreatable progression or TACE failure/refractoriness or any cause of death, whichever occurs first, as determined by the investigator (INV).
Overall Survival (OS)
时间窗: Randomization to death from any cause (up to approximately 94 months)
Overall survival (OS) after enrollment is defined as the time from randomization to death from any cause.
次要结局
- Time to Untreatable (unTACEable) Progression (TTUP) as Determined by Investigator(Randomization to untreatable (unTACEable) progression (up to approximately 46 months))
- Time to Progression (TTP) as Determined by Investigator(Randomization to unTACEable progression or TACE failure/refractoriness (up to approximately 46 months))
- Time to Extrahepatic Spread (EHS) as Determined by Investigator(Randomization to first evidence of EHS (up to approximately 46 months))
- Objective Response Rate (ORR), as Determined by Investigator(Randomization up to approximately 46 months)
- Duration of Responses (DOR) as Determined by Investigator(First occurrence of a documented objective response to disease progression or death from any cause (whichever occurs first)(up to approximately 46 months))
- Progression Free Survival (PFS)(Randomization to first occurrence of disease progression or death from any cause (whichever occurs first)(up to approximately 94 monthsJ))
- Time to Deterioration (TTD)(Randomization to first deterioration (up to approximately 94 months))
- Percentage of Participants With Adverse Events(Baseline up to approximately 94 months)
