A Study of GPC3-targeted T Cells by Intratumor Injection for Advanced HCC (GPC3-CART)

April 22, 2017 updated by: Shanghai GeneChem Co., Ltd.

An Open-label, Uncontrolled, Single-arm Pilot Study to Evaluate Intratumor Injection Mediated GPC3-targeted Chimeric Antigen Receptor T Cells in Advanced Hepatocellular Carcinoma

In this study, CART cells are targeted to GPC3 by intratumor injected that we hope by this means could improve the local CAR-T cell numbers, meanwhile reduce the potential side effects.

Intervention / Treatment

Detailed Description

Patients treated with leukapheresis to obtain peripheral blood mononuclear cells, and then PBMC are purified. T cells are activated and then re-engineered to express chimeric antigen receptors (CARs) specific for GPC3. Cells are expanded in culture and returned to the participant by intratumor injection at the dose of(1-10)×106 CAR positive T cells. The cells perfusion process would only last for (1-2) min. GPC-CART cells are injected into each tumor focus only once.

  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: GPC3-CART cells
Intratumol injection as a local drug delivery pathway, so that more T cells gathered at the tumor site, less T cells to migrated to the normal tissue, thereby enhancing the efficacy of anti-tumor, reducing the potential of side effects. And GPC3-CART is a 2nd CAR, with GPC3 as the target protein, 4-1BB as a co- stimulator
