No prior systemic treatment for advanced HCC. 8. Subjects with hepatitis B virus (HBV) infection are willing to continue receiving antiviral treatment while on study. 9. Subjects have adequate organ and marrow function. 10. Female subjects with childbearing potential must have negative serum pregnancy test result at screening. Female subjects with childbearing potential, and male subjects and their female partners with childbearing potential must agree to use a contraceptive method(s) detailed in the protocol from the day of signing informed consent form (ICF), during the study and till at least 6 months after the last dose.

Exclusion criteria 1

  1. 1.Fibrolamellar HCC, sarcomatoid HCC, cholangiocellular carcinoma or mixed cholangiocarcinoma and HCC. 2. A prior bleeding event due to esophageal or gastric varices within 6 months or other gastrointestinal bleeding events within 28 days prior to screening. Untreated or incompletely treated esophageal or gastric varices that are considered by the investigator to be at high-risk for bleeding (Note: Patients must undergo an esophagogastroduodenoscopy [EGD], and all size of varices [small to large] must be assessed and treated per local standard of care prior to enrollment; patients who have undergone an EGD within 6 months prior to the initiation of study treatment do not need to repeat the procedure). Active gastric or duodenal ulcer. 3. Malabsorption syndrome or inability to take oral medication due to other causes. 4. HBV and HCV co-infection. 5. Surgery or locoregional therapy for palliative purpose (e.g., to treat bone metastases or metastases causing nerve impingement) within 4 weeks prior to study treatment. 6. History of other malignancy(ies) in the past 5 years, except for malignant disease treated with curative intent and without active disease. 7. Known history of human immunodeficiency virus (HIV) infection or acquired immunodeficiency syndrome (AIDS). 8. Current or prior use of systemic corticosteroid (> 10 mg/day prednisone or equivalent) or other immunosuppressive medication within 14 days prior to the first dose of study treatment. 9. History of bone marrow transplantation or organ transplantation. 10. History of anaphylaxis or hypersensitivity to any ingredient of the investigational product. 11. Any contraindication of lenvatinib. 12.Known history of drug abuse that would interfere with cooperation with the requirements of the trial. 13. Pregnant or lactating female subjects. 14. History of psychiatric disease that would interfere with cooperation with the requirements of the trial; lack of or with restricted physical capability. 15.
