Arms of the Study

Arm 1

Arm Type

Arm Label

CAR-T cell therapy group

Arm Description

Appropriate patients who could benefit from the GPC3 and TGFβ targeting CAR-T cell therapy against HCC are chosen to be the CAR-T cell therapy group.

Outcomes

Primary Outcome Measures

Number 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-T2-CAR T cells, which is irreversible, or life threatening or hematologic or non-hematologic Grade 3-5.

Secondary Outcome Measures

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.
Median CAR-T cell persistence
Median CAR-T cell persistence will be measured by quantitative rt-PCR.

5. Study Description

Brief Summary
The third/fourth generation of CAR-T cells that target GPC3 (GPC3-CART cell) and/or soluble TGFβ (GPC3/TGFβ-CART )have been constructed and their anti-HCC function has been verified by multiple in vitro and in vivo studies. Clinical studies will be performed to test the anti-cancer function by the GPC3/TGFβ-CAR-T cells in human HCC patients with GPC3 expression. In this phase I study, the safety, tolerance, and preliminary efficacy of the GPC3/TGFβ-CAR-T cell immunotherapy on human will firstly be tested.
Detailed Description
Choose appropriate patients with advanced hepatocellular carcinoma,with written consent for this study; Perform biopsy to determine the expression of GPC3 of the tumor by western blotting or IHC; Collect blood from the patients and isolate mononuclear cells, activate the T cells and transfect the T cells with GPC3/TGFβ targeting CAR (or/and scfv/cytokines-secreting), amplify the number of transfected T cells as needed, test the quality and killing activity of the GPC3/TGFβ-CART cells and then transplant back the patients via systemic or local infusions (via artery or intra-tumor), and follow up closely to collect related results as needed; 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-DAP10-CAR with knockdown of PD1/HPK1; Evaluate the clinical results as needed. Will also perform the similar clinical trial on lung squamous carcinoma with the GPC3 expression.
