Study of GPC-3 CAR-T Cells in Advanced Hepatocellular Carcinoma
Hepatocellular carcinoma is a highly heterogeneous disease. Treatment strategies for advanced hepatocellular carcinoma are limited. Phosphatidylinositol proteoglycan 3 (GPC3) is a heparan sulfate glycoprotein (HSPG) on the surface of the cell membrane. It is highly expressed in liver cancer tissues, but hardly expressed in normal liver tissues. It is an ideal target for tumor treatment. Investigators aimed to test the safety and efficacy of GPC3 CAR-T cells in patients with advanced hepatocellular carcinoma.
• 40\
‣ 70 years old;
• Patients with advanced hepatocellular carcinoma (HCC) diagnosed by histopathology or cytology, who are not suitable for surgery or local treatment (including ablation therapy, interventional therapy and radiotherapy), and who have experienced progress or intolerance after receiving standard treatment in the past;
• Patients who have been terminated for more than 28 days due to previous ineffective PD-1 monoclonal antibody treatment;
• At least one target lesion that can be evaluated stably according to RECIST 1.1 standard is defined as: the longest diameter of non lymph node lesions ≥ 10mm, or the short diameter of lymph node lesions ≥ 15mm; Intrahepatic lesions require enhanced imaging in arterial phase;
• Tumor tissue samples were positive for GPC3 by immunohistochemistry (IHC);
• Grade C according to Barcelona liver cancer grading standard (BCLC) or Grade B which is not suitable for local treatment/progression of local treatment;
• Estimated survival time \> 12 weeks;
• Cirrhotic state Child Pugh score Grade A
• ECOG physical status score 0\

⁃ If the patient is HBsAg positive or HBcAb positive, HBV-DNA\<200IU/ml. HBsAg positive patients must receive antiviral treatment according to the Guidelines for the Prevention and Treatment of Chronic Hepatitis B (2015);
⁃ Single vein access;
⁃ Blood routine test: WBC ≥ 2.5 × 109/L, PLT≥60 × 109/L, Hb≥9.0 g/dL,LY≥0.4 × 109/L;
⁃ Blood biochemistry: serum Alb ≥ 30 g/L, serum lipase and amylase ≤ 1.5 ULN, serum creatinine ≤ 1.5 ULN and endogenous creatinine clearance rate ≥ 40mL/min, ALT ≤ 5ULN, AST ≤ 5ULN, total bilirubin ≤ 2.5ULN, prothrombin time extension ≤ 4s;
⁃ The women of childbearing age must carry out serum pregnancy test within the screening period and 14 days before starting the study medication, and the result is negative. They are willing to use reliable methods of contraception during the test period (within 12 months (M12) after cell infusion); For male subjects whose partners are women of childbearing age, they should have undergone sterilization or agree to use reliable methods of contraception during the trial
