Abstract
A substantial proportion of patients with hepatocellular carcinoma have to face up,
sooner or later, to systemic therapy. The current standards as first line systemic
therapies are either atezolizumab (anti-PD-L1) plus bevacizumab (anti-VEGF), or durvalumab
(anti-PD-L1) plus tremelimumab (anti-CTLA-4). However, the median overall survival
remains below 20 months, and a minority of patients become long-term survivors. Of
interest in immune-oncology strategies for hepatocellular carcinoma, the objective
response seems to be the most reliable surrogate marker of better overall survival.
TRIPLET-HCC (NCT05665348) is a multicentre, randomised, open-label phase II-III trial
designed to evaluate efficacy and safety of the triple combination by the addition
of ipilimumab (anti-CTLA-4) to atezolizumab/bevacizumab, versus the double atezolizumab/bevacizumab
combination. The main inclusion criteria are histologically proven BCLC-B/C HCC without
previous systemic therapy. The primary objective of the phase II is the objective
response rate in the triple arm, and OS in the triple versus double arms in the phase
III. Secondary endpoints common to the phases II and III are the comparisons of progression-free
survival, objective response rates, tolerance and quality of life. In addition, genetic
and epigenetic studies from tissue and circulating DNA/RNA will be conducted to assess
their prognostic or predictive value.
