• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Zhejiang University
• Treatments: Antibodies; Antibodies, Monoclonal; Lenvatinib

Criteria

Inclusion Criteria:

• 1.Voluntary participation and able to sign the informed consent form

• 2. Aged 18 to 75 years at screening

• 3. Patients with histologically confirmed hepatocellular carcinoma (HCC) who meet the following requirements: a. Barcelona Clinic Liver Cancer Stage B or C (BCLC B/C) b. Child-Pugh score ≤ 6 c. GPC3 is possibly expressed in tumor tissues

• 4. Patients with relapsed / progressive disease after at least one prior standard systemic therapy for HCC, or ineligible to accept/unable to tolerate the systemic therapies. Standard systemic therapies may include targeted drugs (such as Sorafenib, Lenvatinib, Donafenib, Apatinib), immune checkpoint inhibitors (such as Atezolizumab, Pembrolizumab, Camrelizumab, Sintilimab, Nivolumab, Toripalimab, Tislelizumab) or chemotherapeutic drugs (such as Oxaliplatin and 5-Fu). Subjects in the C-CAR031 plus Lenvatinib group must meet the following criteria: (1) have not received prior Lenvatinib therapy; (2) Progression or intolerance to prior systemic therapy with first-line PD-1 (L1) monoclonal antibody, or contraindication to 1st line PD-1(L1) monoclonal antibody-based systemic therapy. Subjects in the C-CAR031 combination with PD-1 (L1) monoclonal antibody group must meet the following requirements: (1) have not received PD-1 (L1) monoclonal antibody therapy before; (2) Progression or intolerance to prior systemic therapy with first-line hepatocellular carcinoma targeted drugs (Sorafenib, Lenvatinib, Donafenib), or contraindications to first-line hepatocellular carcinoma targeted drugs (Sorafenib, Lenvatinib, Donafenib).

Total bilirubin (TBIL) ≤ 2 × upper limit of normal (ULN) f. AST and ALT ≤ 5 × ULN g. Serum creatinine ≤ 1.5 × ULN h. Prothrombin time (PT): prolonged PT ≤ 4 s

• 11. Patients without history of HBV infection, or with HBV DNA < 2000 IU/mL (or 10000 copies/mL) at screening who agree to receive anti-virus therapies throughout the study according to the guidelines

• 12. Negative serum or urine pregnancy test results for females of child-bearing age at screening; In addition, they should agree to take effective contraceptive measures throughout the study

• 13. Patients who agree to abstain from drinking throughout the study
