4. For cohorts A and B: No prior systemic anti-cancer treatment for hepatocellular carcinoma.
5. At least one measurable lesion according to RECIST v1.1 criteria.
6. Child-Pugh liver function score ≤7. ECOG performance status of 0 or 1.
7. Clinically controllable HBV or HCV infection.
8. Adequate organ and bone marrow function.

Exclusion Criteria:
