Criteria

Inclusion Criteria:

• Written informed consent should be signed before implementing any trial-related procedures;

• Age ranges from 18 to 75 years old.

• CNLC-IIIa and IIIb HCC based on the Criteria for diagnosis and treatment of hepatocellular carcinoma (2019 edition)

• At least ≥ 1 measurable lesions per RECIST 1.1;

• Child-Pugh grade A;

• ECOG PS scores 0-1;

• No prior therapy for HCC.

• Expected survival time > 6 months;

• Sufficient organ functions, the subjects need to meet the following laboratory indicators:

• No blood transfusion, no use of hematopoietic stimulators (including g-csf, gm-csf, EPO and TPO) and infusion of human albumin preparations within 14 days prior to screening:Neutrophil absolute count ≥1.5×10^9/L;Platelet count ≥ 100×10^9/L;Hemoglobin ≥ 9 g/dL

• Total bilirubin ≤ 1.5 × upper limit of normal (ULN); or total bilirubin > ULN but direct bilirubin ≤ ULN

• Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤5 × ULN;

• Serum creatinine ≤ 1.5 × ULN and creatinine clearance rate (calculated by Cockcroft-Gault formula) ≥ 60 ml/min;

• International Normalized Ratio (INR) or Prothrombin Time (PT) ≤ 1.5 × ULN

• Normal thyroid function, defined as thyroid stimulating hormone (TSH) within the normal range. If the baseline TSH exceeds the normal range, the subjects can also be included in the group in case total T3 (or FT3) and FT4 are within the normal range;

• Myocardial enzyme spectrum should be within the normal range (if the investigator comprehensively judges that the simple laboratory abnormality is not clinically significant, the subject is also included);

• Female subjects of childbearing age should receive a urine or serum pregnancy test and the result is negative, 3 days prior to accept the first study drug administration (day 1 of cycle 1). In case the urine pregnancy test result cannot be confirmed as negative, a blood pregnancy test is required. Meanwhile, voluntary use of appropriate contraceptive methods shall be taken during the observation period and within 8 weeks of the last administration of the study drug; Women of non-bearing age are defined as at least 1 year after menopause, or those who have undergone surgical sterilization or hysterectomy; For males, appropriate contraceptive methods should be taken during the observation period and within 8 weeks after the last dose of the study drug.

• If there is a risk of pregnancy, all subjects (regardless of male and female) need to adopt contraceptives with an annual failure rate of less than 1% during the entire treatment period until 120 days after the last administration of the study drug (or 180 days after the last chemotherapeutic drug administration).
