Individualized Comprehensive Treatment for Advanced Hepatocellular Carcinoma

This project is a prospective, multi-center, multi-cohort exploratory clinical study. It focuses on patients with advanced hepatocellular carcinoma who experience disease progression after first-line standard therapy. Based on different patterns of disease progression, patients will receive relevant systemic treatments, either with or without local interventional therapy. The primary endpoint is progression-free survival (PFS), while secondary endpoints include overall survival (OS), 1-year OS rate, objective response rate (ORR), disease control rate (DCR), duration of remission (DOR), and safety. Additionally, the study will explore the correlation between patients' clinical pathological characteristics, serum biomarkers, and clinical efficacy.

8. The subjects voluntarily joined the study, signed the informed consent, had good compliance, and cooperated with the follow-up

Exclusion Criteria:

1. Pathological types of other non-hepatocellular carcinomas, including fibrolamellar hepatocellular carcinoma, sarcomatoid hepatocellular carcinoma, cholangiocarcinoma, etc. previously confirmed by histology/cytology
2. Child-Pugh grade of liver function ≥7 points
3. Major cardiovascular impairment in the 6 months prior to initial administration of the drug, such as a New York Heart Association (NYHA) Class II or higher history of congestive heart failure, unstable angina, myocardial infarction or stroke, or arrhythmia associated with hemodynamic instability; Corrected QT (QTc) interval lengthening \>480ms
4. Other malignancies developed ≤ 5 years before the first dose, except for fully treated cervical carcinoma in situ, basal cell or squamous cell skin cancer, local prostate cancer after radical surgery, and ductal carcinoma in situ after radical surgery (hormone therapy for non-metastatic prostate cancer or breast cancer is allowed)
5. Have had an active autoimmune disease in the past 2 years that requires systemic treatment, including but not limited to autoimmune hepatitis, lupus erythematosus, etc
6. Uncontrolled active infection, such as active tuberculosis, HIV infection, etc.; Patients with HBV-DNA replication level below 10000IU/mL and continuous oral antiviral therapy could be enrolled.

8. Use of live attenuated vaccine within 28 days prior to randomization, or anticipated use of such live attenuated vaccine during the study period (patients are not allowed to receive live attenuated influenza vaccine 4 weeks prior to randomization, during treatment, and within 5 months after the final administration of adbelizumab)
9. Received any other investigational drug treatment or participated in another interventional clinical study within 4 weeks prior to signing the ICF
10. Use of corticosteroids (\> 10 mg/ day prednisone or equivalent dose) or other immunosuppressants within ≤ 14 days prior to the first dose of the study drug. Allowing inhaled or topical use of steroids and adrenal replacement steroids in the absence of active autoimmune disease; Patients received systemic immunosuppressive drugs (including but not limited to glucocorticoids, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-tumor necrosis factor \[anti-TNF\] drugs) within 1 week prior to randomization. Patients receiving short-term, systemic immunosuppressant therapy, such as glucocorticoids for nausea, vomiting, or anaphylaxis management or prevention, may be enrolled in the study after investigator review. To allow the use of inhaled corticosteroids in patients with chronic obstructive pulmonary disease, corticosteroids such as fluhydrocortisone in patients with postural hypotension, and low-dose glucocorticoid supplements for adrenal insufficiency; Known mental illness, alcoholism, inability to quit smoking, drug or substance abuse
11. In the investigator's judgment, the subjects have other factors that may lead to the forced termination of the study, such as non-compliance with the protocol, other serious illnesses (including mental illness) requiring combined treatment, serious laboratory abnormalities, family or social factors that may affect the safety of the subjects, or the collection of data and samples
