A Study Evaluating Atezolizumab and Bevacizumab, With or Without Tiragolumab, in Participants With Untreated Locally Advanced or Metastatic Hepatocellular Carcinoma (IMbrave152)

Brief Summary
The purpose of this study is to assess the efficacy and safety of tiragolumab, an anti-TIGIT monoclonal antibody, when administered in combination with atezolizumab and bevacizumab as first-line treatment, in participants with unresectable, locally advanced or metastatic hepatocellular carcinoma (HCC).

Outcome Description
The following subscales of the EORTC QLQ-C30 will be used for the assessment: global health status/quality-of-life (GHS/QoL), physical functioning and role functioning. GHS and QoL are scored on a 7-point scale: 1=Very poor to 7=Excellent. Functioning items are scored on a 4-point scale: 1=Not at all to 4=Very much, with a higher score indicating a worse outcome. Scores will be linearly transformed with a minimum score of 0 and maximum score of 100. A higher score indicates a better outcome.
