Brief summary
The third generation of GPC3/mesothelin targeted CAR-γδT cells have been constructed and their anti-cancer function has been verified by multiple in vitro and in vivo studies. Clinical studies will be performed to test anti-cancer function of the CAR-γδT cells for immunotherapy of human cancer patients with GPC3 or Mesothelin expressions. In this phase I study, the safety, tolerance, and preliminary efficacy of the GPC3/Mesothelin-CAR-γδT cell immunotherapy on human cancers will firstly be evaluated.
Detailed description
1. Choose appropriate patients with advanced solid cancers, with written consent for this study; 2. Perform biopsy to determine the expression of GPC3 or Mesothelin of the tumors by western blotting or IHC; 3. Collect blood from the patients and isolate mononuclear cells, select and grow γδT cells and transfect the γδT cells with GPC3 or Mesothelin targeting CAR, amplify the transfected γδT cells as needed, test the quality and killing activity of the CAR-γδT cells and then transfer them back the patients via systemic or local injections, and follow up closely to collect related results as required; 4. To enhance the killing capability, cotreatment the patients with PD1/PDL1/CTLA4 antibodies may be applied; 5. Evaluate the clinical results as needed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Patients with Dose Limiting Toxicity | Six months | A dose limiting toxicity is defined as any toxicity that is considered to be primarily related to the γδT cells, which is irreversible, or life threatening or hematologic or non-hematologic Grade 3-5. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percent of Patients with best response as either complete remission or partial remission. | Six months | 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. |
| Median γδT cell persistence | Six years | Median γδT cell persistence will be measured by quantitative rt-PCR. |
