ClinConnect Summary
This clinical trial is investigating a new treatment called CAR-T cell therapy for patients with advanced liver cancer, specifically a type called hepatocellular carcinoma (HCC) that expresses a protein known as GPC3. The goal of the study is to determine how safe and effective this therapy is. In the first phase of the trial, six patients will receive a specific dose of GPC3-targeted CAR-T cells through a procedure that delivers the cells directly to the liver. Depending on how well this treatment works and its safety, the study may adjust the dose for the next group of patients. If successful, a larger group of 10-20 more patients will also receive this therapy.
To be eligible for the trial, participants need to be between 18 and 70 years old and have been diagnosed with advanced HCC that has progressed despite previous treatments. They must have a measurable tumor that tests positive for the GPC3 protein. Participants will need to meet certain health criteria, including good organ function, and will be required to sign consent forms to participate. Throughout the trial, patients will be closely monitored to ensure their safety and to gather data on how well the treatment works. This trial is currently not yet recruiting participants, but it presents a potential new option for those with limited treatment choices for advanced liver cancer.

Eligibility criteria
- Inclusion Criteria:
- • Age: 18 to 70 years old (inclusive); gender unrestricted.
- Diagnosis of advanced Hepatocellular Carcinoma (HCC), meeting the following requirements:

- • History of allogeneic tissue/organ transplantation (including bone marrow, stem cell, liver, or kidney transplants), except those that do not require immunosuppressive therapy (e.g., corneal or hair transplants).
- • Prior treatment targeting GPC3.
- • Receipt of anti-tumor treatment for liver cancer or any other medical intervention that could impair major organ function within four weeks before signing informed consent.
- • Known central nervous system metastasis.
- * Presence of clinically significant systemic disease (e.g., severe active - - infections, significant heart, lung, liver, kidney, or neurological dysfunction) that, in the investigator's opinion, may impair the patient's ability to tolerate the study treatment or increase the risk of complications. Including but not limited to:
- • 1. Uncontrolled severe active infection.
- • 2. Symptomatic congestive heart failure (NYHA Class II-IV).
- • 3. Clinically significant severe aortic valve stenosis or symptomatic mitral valve stenosis.
- • 4. QTc \> 450 msec on ECG, or QTc \> 480 msec in patients with bundle branch block.
- • 5. Uncontrolled clinically significant arrhythmias within six months before signing informed consent.
- • 6. Acute coronary syndrome (e.g., unstable angina or myocardial infarction) within six months before signing informed consent.
- • 7. Hypertension not controlled by medication (systolic BP ≥ 160 mmHg and/or diastolic BP ≥ 100 mmHg).
- • 8. Cerebrovascular accidents, including transient ischemic attack (TIA), cerebral infarction, cerebral hemorrhage, or subarachnoid hemorrhage within six months before signing informed consent.
- • 9. Active, chronic, or recurrent severe autoimmune disease (within one year before signing informed consent), or liver cirrhosis/liver cancer caused by autoimmune hepatitis.
- • 10. Any form of primary or secondary immunodeficiency, such as severe combined immunodeficiency (SCID).
- • 11. Risk of organ perforation or hemorrhage, as determined by the investigator.
- • History of severe systemic hypersensitivity to study drugs/components \[e.g., fludarabine, cyclophosphamide, dimethyl sulfoxide (DMSO), low molecular weight dextran, human serum albumin (HSA)\].
- • Receipt of live attenuated vaccine within four weeks before signing informed consent.
- • Participation in another clinical trial within four weeks before signing informed consent.
- • History of another malignancy within the past five years, excluding adequately treated non-melanoma skin cancer or carcinoma in situ (e.g., breast, stomach, colon, bladder, cervix, or melanoma).
- • History of neuropsychiatric disorders diagnosed by ICD-11 criteria, or any neuropsychiatric disorder deemed by the investigator to warrant exclusion, including but not limited to epilepsy, schizophrenia, dementia, or addiction to drugs/alcohol.
- • Any other condition that, in the investigator's opinion, makes the patient unsuitable for this clinical trial.
