CAR-T Cell Targeting GPC3 for Immunotherapy of Hepatocellular Carcinoma: Phase I Clinical Trial

• Status: Recruiting
• Phase: Phase 1
• Study type: Interventional
• Enrollment: 30 (estimated)
• Sponsor: Second Affiliated Hospital of Guangzhou Medical University · Academic / Other
• Sex: All

• Healthy volunteers: Not accepted

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

1. Choose appropriate patients with advanced hepatocellular carcinoma,with written consent for this study; 2. Perform biopsy to determine the expression of GPC3 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/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; 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-DAP10-CAR with knockdown of PD1/HPK1; 5. Evaluate the clinical results as needed. 6. Will also perform the similar clinical trial on lung squamous carcinoma with the GPC3 expression.
