Brief summary: This study is conducted in patients with advanced hepatocellular carcinoma (HCC). This study includes three arms: A, B, and C. Arm A will receive HLX07 combination therapy with HLX10 and HLX04 as first line treatment. Arm B will receive HLX07 combination therapy with lenvatinib as second line treatment. Arm C will receive HLX07 monotherapy as third-line or above treatment. All of eligible patients will receive study drug treatment until loss of clinical benefit, unacceptable toxicity, death, withdrawal of informed consent (whichever occurs first, HLX10 treatment up to 2 years).

5. According to the curative effect evaluation criteria in solid tumors (RECIST) v1.1, assessed by the investigator with at least one measurable lesions. Measurable target lesions cannot be selected from the site of previous radiotherapy.

   (lesions located in the usual radiation area, if confirm progress, can also be selected as the target lesion).

7. Arm B,C: The end of previous systematic treatment() must be ≥ 2 weeks before the first administration of the study drug, and the treatment-related AE should be restored to the level of NCI -CTCAE ≤ 1 (except hair loss).
8. The patient with HCC has liver surgery or local treatment (hepatic artery embolization, TACE, hepatic artery infusion, radiofrequency ablation, cryoablation or percutaneous ethanol injection) , Arm A and B : treatment was received ≥ 4 weeks prior to the first administration of this study. Arm C: treatment was received ≥ 2 weeks prior to the first administration of this study; The palliative radiotherapy for bone metastases was received ≥ 2 weeks prior to the first administration of this study; The diagnostic liver puncturewas received ≥ 1weeks prior to the first administration of this study. AEs related to previous local therapy should be recovered to the level of NCI -CTCAE ≤ 1.
9. The ECOG physical performance score within 7 days before the first administration of the study drug was 0 or 1.

Subjects with negative HCV antibody (-) or HCV-RNA were admitted. If HCV-RNA is positive, must agree to receive standard of anti-virus treatment, and subjects must have ALT and AST ≤ 3×ULN to be enrolled. Subjects with co-infection of hepatitis b and c should be excluded.
