简要总结
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.
详细描述
- 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.

结局指标
主要结局
Number of Patients with Dose Limiting Toxicity
时间窗: three months
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.
次要结局
- Percent of Patients with best response as either complete remission or partial remission.(three months)
- Median CAR-T cell persistence(Five years)
