HBV/HCV co-infected patients will be excluded. Patients with a history of HCV infection but with negative HCV RNA PCR results can be considered uninfected with HCV.
11. Female patients of childbearing potential must receive serum pregnancy test within 7 days before enrollment, have negative result, and agree to use reliable and effective contraceptive methods during the trial and within 60 days after the last dose of study drug.

12. Being voluntary to participate in the study, sufficiently informed consent and signature of written informed consent form, with good compliance.

Patients can not be enrolled in the study if any one of the following criteria is fulfilled:

1. Known cholangiocellular carcinoma (ICC) or mixed hepatocellular carcinoma, sarcomatoid hepatocellular carcinoma and hepatic fibrolamellar carcinoma.
2. Malignant tumor except HCC in the past 5 years: however, localized tumor cured in the study is excluded, including cervical carcinoma in situ, skin basal cell carcinoma and carcinoma in situ of prostate.
3. Hepatic surgery and/or local therapy or treatment with investigational product for HCC within 4 weeks prior to enrollment; palliative therapy for bone metastatic lesion within 2 weeks prior to enrollment. Toxicity reaction induced by previous therapy (except alopecia) not recovered to ≤ grade 1 (NCI-CTCAE v5.0). Chinese medicine preparation with anti-liver cancer effect within 2 weeks prior to enrollment.
4. Uncontrolled pericardial effusion, uncontrolled pleural effusion or clinically obvious moderate peritoneal effusion at screening,
5. History of gastrointestinal hemorrhage within 6 months prior to enrollment; the patients with portal hypertension need to receive gastroscopy to exclude the patients with "red sign", if they are considered by investigators to have high risk for hemorrhage . The patient needs to be excluded if there is a history of "red sign" in gastroscopy.
6. Having ≥ grade 3 (NCI-CTCAE v5.0) gastrointestinal or non-gastrointestinal fistula at present.
7. Patients with cancer thrombus in the main trunk of portal vein (Vp4), or cancer thrombus in inferior vena cava should be excluded. However, the patients with cancer thrombus in the main trunk of portal vein but unobstructed branch of contralateral portal vein are allowed to be enrolled.
8. Previous history of serious cardiovascular and cerebrovascular diseases:
9. Having major bleeding and coagulation disorders or other obvious evidence on hemorrhagic tendency:
10. Medium to large surgical treatment within 4 weeks prior to enrollment, however, not including diagnostic biopsy.
11. Central nervous system metastasis.
12. Serious, uncured wound, active ulcer or untreated bone fracture.
13. Vaccination of live vaccine within 30 days prior to enrollment.
14. Active autoimmune diseases requiring systemic treatment (i.e., immunomodulatory drug, corticosteroid or immunosuppressant) in the past 2 years; however, replacement therapy (e.g., thyroxine, insulin or physiological corticosteroid replacement therapy for renal or pituitary insufficiency) will not be considered as systemic therapy and is allowed to be used, and enrollment is allowed.
