Randomised, Open-label, Phase II-III Study Evaluating the Benefit of Adding Ipilimumab to the Combination of Atezolizumab and Bevacizumab in Patients With Hepatocellular Carcinoma Receiving First-line Systemic Therapy
TRIPLET HCC is a phase II-III trial that assess the effectivness of addition of ipilimumab to the combination atezolizumab-bevacizumab, on global survival and response to the treatment, for patients with advanced or metastatic hepatocellular carcinoma. The theoretical duration of the study is 5 years. In the scope of this study, each patient will have 2 years of treatment and 2 years of follow-up from their enrollment date.

• WHO 0 or 1
• HCC not amenable to curative treatment by surgery, thermo-ablation or liver transplantation, or to intra-arterial palliative treatment (IAP) for intermediate BCLC-B HCC.
⁃ Advanced (BCLC-C) or intermediate (BCLC-B) HCC after failure or contraindication of the CEL
