Brief summary: A study that aimed to assess the safety and anti-tumor activity of CCAR031 injection in unresectable HCC patients.

Detailed description: This study plans to enroll 8-44 patients to assess the safety of C-CAR031. Subjects who meet the eligibility criteria will either receive a single dose of C-CAR031 injection, and will be followed up post-treatment for safety monitoring，or further explore the treatment modality of combination with Lenvatinib or PD-1(L1) monoclonal antibody at explored safe and effective dose level(s) of C-CAR031 monotherapy in specific eligible advanced HCC patients to provide data support for the phase II study of CAR-T combination therapy. The follow-up period will be 12 months.

Eligibility 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).
* 5. At least one measurable target lesion (as per RECIST v1.1)
* 6. WHO/ECOG performance status (PS) score of 0 or 1 point
* 7. Expected survival ≥ 12 weeks
* 8. Left ventricular ejection fraction (LVEF) by echocardiography ≥ 45%
* 9. No active infection in the lungs
* 10. Laboratory tests: a. Absolute neutrophil count (ANC) ≥ 1.0 × 109/L b. Lymphocyte count ≥ 0.4 × 109/L c. Platelet count ≥ 60 × 109/L d. Hemoglobin ≥ 80 g/L e. 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
