Universal CAR-T Cells (REVO-UWD-03) for Advanced Hepatocellular Carcinoma and Lung Cancer

This is an investigator initiated trial to assess the efficacy and safety of a GPC3-targeting CAR-T therapy (REVO-UWD-03) in the HCC and Lung Cancer. It also aims to explore the feasibility of using a novel universal CAR-T cell platform.

The study will use T cells from healthy donors, modified using a novel universal CAR-T technology, to treat HCC and Lung Cancer patients. The antigen-binding site of the CAR molecule recognizes GPC3 as the target.

The main questions it aims to answer are: • What is the maximum tolerated dose (MTD) of GPC3-CAR-T therapy in universal CAR-T cell treatments? • What are the dose-limiting toxicities (DLT) and treatment-emergent adverse events (TEAE)? • What is the treatment efficacy, as measured by objective response rate (ORR) and progression-free survival (PFS)? Researchers will assess whether the universal CAR-T cells have good safety and efficacy in treating HCC or Lung cancer, while improving accessibility and lowering treatment costs. Participants will: • Receive universal GPC3-CAR-T cells through a 3+3 dose escalation scheme. • Undergo chemotherapy conditioning before CAR-T infusion. • Be monitored for adverse events, immune response, and disease progression.

The study will collect data on both short-term outcomes (within the first few months post-treatment) and long-term safety and efficacy.

Exclusion Criteria:

* Pregnant or breastfeeding women; Receipt of chemotherapy, targeted therapy, other experimental drugs, or monoclonal antibody treatment within 14 days before enrollment for cell collection; Participation in other drug clinical trials within 4 weeks prior to the start of the study; Presence of any of the following cardiovascular or cerebrovascular diseases or risk factors: a. Myocardial infarction, unstable angina, acute or persistent myocardial ischemia, grade 3 or 4 heart failure (according to NYHA classification), symptomatic or poorly controlled severe arrhythmia, cerebrovascular accident, transient ischemic attack, or other serious cardiovascular diseases within 6 months prior to enrollment; b. History of myocarditis, primary cardiomyopathy, or specific cardiomyopathy; c. Any events of disseminated intravascular coagulation (DIC), peripheral arterial thromboembolism, pulmonary embolism, or other severe thromboembolic events within 3 months prior to enrollment; d. Presence of aortic aneurysm, aortic dissection, or other major vascular diseases requiring surgery within 6 months prior to enrollment or posing a life-threatening risk; e. QTcF interval \>480 ms; f. Left ventricular ejection fraction (LVEF) \<50% on ECHO; Long-term unhealed wounds or fractures; History of substance abuse or psychiatric disorders that cannot be controlled or a history of mental illness; Uncontrolled or active fungal, bacterial, viral, or other infections; Toxicities from previous anti-tumor treatments not yet recovered to grade ≤1 or to the levels specified in the inclusion/exclusion criteria; Known HIV infection; active syphilis infection; or active hepatitis B (HBsAg positive, and HBV-DNA ≥500 IU/mL or above the detection limit, whichever is higher) or hepatitis C (HCV antibody positive, and HCV-RNA above the detection limit); Uncontrollable pleural effusion, pericardial effusion, or ascites requiring repeated drainage despite appropriate intervention; History of severe allergic reactions to key study medications (including fludarabine, cyclophosphamide, mesna, tocilizumab, or anti-infection drugs used during the preconditioning phase); Active autoimmune diseases requiring systemic treatment within two years (including but not limited to autoimmune hepatitis, uveitis, colitis, hypophysitis, vasculitis, nephritis, or hyperthyroidism); hormone replacement therapy, such as thyroid hormones, insulin, or physiological corticosteroid replacement for adrenal or pituitary insufficiency, is not considered systemic treatment; Female subjects unwilling to use contraception from the time of signing the consent form until 6 months after completion of CAR-T cell infusion; Patients with meningeal metastasis, brainstem metastasis, spinal cord metastasis and/or compression, active or untreated CNS metastasis; History of interstitial lung disease (ILD) or non-infectious pneumonia requiring steroid treatment; Clinically significant lung damage due to pulmonary complications, including but not limited to any underlying lung disease (e.g., pulmonary embolism, severe asthma, or severe chronic obstructive pulmonary disease (COPD) within 3 months prior to enrollment), or any autoimmune, connective tissue, or inflammatory disease affecting the lungs (e.g., rheumatoid arthritis, sarcoidosis), or prior complete lung resection; Any condition that the investigator believes may interfere with drug evaluation, the safety of the subject, or study outcomes, or any condition deemed inappropriate by the investigator for study participation.
