5. At least one measurable lesion per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) and modified RECIST (mRECIST).
6. No prior systemic antineoplastic therapy for unresectable HCC before first dose administration.
7. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, with no deterioration within 2 weeks prior to first study drug administration.
8. Adequate organ function as specified.
9. Negative serum pregnancy test within 7 days prior to first dose (women of childbearing potential). Pregnant or lactating women are not eligible for this study.
