The third generation of CAR-T cells that target GPC3, Mesothelin, Claudin18.2, GUCY2C, B7-H3, PSCA, PSMA, MUC1, TGFβ, HER2, Lewis-Y, AXL, or EGFR have been constructed respectively and their anti-cancer function has been verified by multiple in vitro and in vivo studies.Clinical studies will be performed to test the anti-cancer function of the these individual or combination of the CAR-T cells for immunotherapy of human cancer patients with GPC3, Mesothelin, Claudin18.2, GUCY2C, B7-H3, PSCA, PSMA, MUC1, TGFβ, HER2, Lewis-Y, AXL, or EGFR expressions. In this phase I study, the safety, tolerance, and preliminary efficacy of the GPC3/Mesothelin/Claudin18.2/GUCY2C/B7-H3/PSCA/PSMA/MUC1/TGFβ/HER2/Lewis-Y/AXL/EGFR -CAR-T cell immunotherapy on human cancers will firstly be tested.
1. Choose appropriate patients with advanced lung or other cancers,with written consent for this study; 2. Perform biopsy to determine the expression of HER2, Mesothelin, Lewis-Y, PSCA, MUC1, GPC3, AXL, EGFR, Claudin18.2, or B7-H3 of the tumor by western blotting or IHC; 3. Collect blood from the patients and isolate mononuclear cells, activate the T cells and transfect the T cells with GPC3, Mesothelin, Claudin18.2, GUCY2C, B7-H3, PSCA, PSMA, MUC1, TGFβ, HER2, Lewis-Y, AXL, or EGFR targeting CAR, amplify the transfected T cells as needed, test the quality and killing activity of the CAR-T cells and then transfer them back the patients via systemic or local injections, and follow up closely to collect related results as needed; 4. To enhance the killing capability, CD4+ T cells are genetically engineered to express TGFβ-CAR and secret IL7/CCL19 and/or SCFVs against PD1/CTLA4/Tigit; CD8+T cells are constructed to express GPC3/Mesothelin/Claudin18.2/GUCY2C/B7-H3/PSCA/PSMA/MUC1/TGFβ/HER2/Lewis-Y/AXL/EGFR -DAP10-CAR with knockdown of PD1/HPK1; 5. Other cancers with these cell surface antigen expressions are also recruited if needed; 6. Evaluate the clinical results as needed.

RECRUITINGNumber of Patients with Dose Limiting Toxicity
A dose limiting toxicity is defined as any toxicity that is considered to be primarily related to the GPC3/Mesothelin/Claudin18.2/GUCY2C/B7-H3/PSCA/PSMA/MUC1/TGFβ/HER2/Lewis-Y/AXL/EGFR-CAR T cells,which is irreversible, or life threatening or hematologic or non-hematologic Grade 3-5.
Time frame: three months
Percent of Patients with best response as either complete remission or partial remission.
Response rates will be estimated as the percent of patients whose best response is either complete remission or partial remission by combining the data from the patients. To compare with historical data, a 95% confidence interval will be calculated for the response rate.
Time frame: three months
Median CAR-T cell persistence
Median CAR-T cell persistence will be measured by quantitative rt-PCR.
Time frame: Six years
