universal car-t cells (revo-uwd-03) for advanced hepatocellular carcinoma and lung cancer

Conditions: HCC - Hepatocellular Carcinoma; NSCLC (Advanced Non-small Cell Lung Cancer)

Summary: 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.

Eligibility criteria:

immunohistochemistry (ihc) assessment shows gpc3 expression in ≥50% of the tumor lesion area with ≥1+ staining (assessment should be conducted on at least five randomly selected tumor regions, and at least five blank slides should be provided for evaluation); at least one measurable lesion; estimated survival time of ≥90 days; normal major organ functions, meeting the following criteria: a. absolute neutrophil count ≥1.5 x 10\^9/l; b. platelet count ≥80 x 10\^9/l; c. hemoglobin ≥9 g/dl; d. liver function: total bilirubin ≤1.5 times the upper limit of normal (uln), for gilbert's syndrome patients, bilirubin ≤2.0 times uln; aspartate aminotransferase (ast) and alanine aminotransferase (alt) ≤3 times uln; e. international normalized ratio (inr) \ 50%; no hemorrhagic disorders or coagulation dysfunctions; women of childbearing potential must have a negative pregnancy test (serum or urine) within 7 days before enrollment and be willing to use appropriate contraception during the study and for 8 weeks after the last car-t administration (women who have undergone sterilization or are postmenopausal for at least 2 years are considered not to have childbearing potential); the subject voluntarily agrees to participate in the study, signs the informed consent form, and demonstrates good compliance for follow-up. 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.
