This Phase 1 single-center, open-label study uses a 3+3 dose-escalation design to test Super CAR-T cell therapy in patients with GPC3-positive advanced hepatocellular carcinoma (HCC). The aim is to evaluate its safety and tolerability. Participants must be aged 18–75 with histologically or cytologically confirmed HCC that is inoperable (stage IIa–IIIb under the Chinese national staging system).
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria:
1. Understand and voluntarily sign the informed consent form prior to participating in any trial-related activities;
2. Be between 18 and 75 years of age; gender is not restricted;
3. Diagnosed with hepatocellular carcinoma (HCC) based on histopathological or cytological examination: Patients classified as inoperable Stage IIa, IIb, IIIa, or IIIb according to the Chinese National Liver Cancer (CNLC) staging system, or Stage C according to the Barcelona Clinic Liver Cancer (BCLC) staging system, or Stage B patients who are inoperable or unsuitable for local treatment; Child-Pugh liver function score ≤ 7;
4. Previous failure of or intolerance to at least two lines of standard systemic therapy;
5. The subject must provide a tumor sample or biopsy specimen collected within the past 2 years that meets the requirements and tests positive for GPC3 expression via immunohistochemistry;
6. At least one measurable lesion according to RECIST 1.1 criteria;
7. ECOG performance status of 0-1;
8. Expected survival of more than 3 months;
9. Echocardiography showing a left ventricular ejection fraction (LVEF) ≥50%;
10. Laboratory test results must meet at least the following criteria:
ANC ≥1.0×10⁹/L; PLT ≥75×10⁹/L; Hb ≥ 75 g/L; Creatinine clearance ≥ 60 mL/min; AST ≤ 5×ULN; ALT≤ 5×ULN; TBIL ≤ 3×ULN;
11. If HBsAg-positive or HBcAb-positive, HBV-DNA must be ≤ 2000 IU/mL;
12. Women of childbearing potential must have a negative pregnancy test prior to receiving study treatment; they must agree to use effective contraception during treatment.
Exclusion Criteria:
1. The subject has undergone major surgery within 2 weeks prior to apheresis, or is expected to undergo major surgery during the trial;
2. The subject is allergic to any component of the drugs to be used in this study, including but not limited to cyclophosphamide, fludarabine, CAR-T products, or their excipients;
3. Has not recovered from adverse reactions related to prior surgery or treatment to Grade ≤ 2; exceptions include alopecia, hyperpigmentation, and other conditions deemed by the investigator not to affect the subject's tolerability;
4. Has a clinically significant central nervous system (CNS) disorder (e.g., epilepsy, severe cerebrovascular stenosis) or other diseases presenting with significant neurological symptoms (including psychiatric disorders);
5. Received radiotherapy, systemic chemotherapy, or immune checkpoint inhibitors for the study disease within 2 weeks prior to apheresis; or received small-molecule targeted therapies such as sorafenib, regorafenib, or lenvatinib within 1 week prior to apheresis;
6. Received systemic glucocorticoid therapy within 7 days prior to single-plasma donation; patients currently using or who have recently used inhaled or topical glucocorticoids, as well as those on physiological-dose replacement therapy, are eligible for enrollment;
7. Any uncontrolled active infection, including but not limited to active tuberculosis or infectious diseases requiring systemic treatment;
8. Known active autoimmune diseases, including but not limited to rheumatoid arthritis, systemic lupus erythematosus, autoimmune hepatitis, multiple sclerosis, and glomerulonephritis (patients with vitiligo are not excluded);
9. History of organ transplantation, autologous/allogeneic stem cell transplantation, or renal replacement therapy;
10. HCV antibody-positive with HCV RNA levels above the lower limit of detection; HIV antibody-positive; syphilis antibody-positive;
11. Currently pregnant or breastfeeding, or planning to become pregnant during the study;
12. Participants deemed by the investigator to be unable or unwilling to comply with the requirements of the study protocol.
