Summary
Brief summary
This is a Phase Ib/II, open-label, multicenter, randomized platform study to evaluate
neoadjuvant immunotherapy combinations in participants with resectable HCC. The study is
designed with the flexibility to open new treatment arms as new agents become available,
close existing treatment arms that demonstrate minimal clinical activity or unacceptable
toxicity, or modify the participant population.
