A Study of GPC3 Redirected Autologous T Cells for Advanced HCC (GPC3-CART)

March 16, 2016 updated by: Shanghai GeneChem Co., Ltd.

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

Intravenous infusion of CART cells in the treatment of solid tumors may be not a suitable choice. Because by intravenous infusion, T cells first entered into the blood circulation, but the number of T cells accumulated at the tumor site is limited, while the probability is high that CART cells contact with normal tissue where target protein is expressed, leading to a more potential off-target side effect. In this study, CART cells infused to the body is mediated by the method of transcatheter arterial infusion(TAI), which is one kind of tumor intervention therapy pathway. We hope by this means could improve the local CAR-T cell numbers，meanwhile reduce the potential side effects.

Detailed Description

Patients treated with leukapheresis from which peripheral blood mononuclear cells 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 transcatheter arterial infusion at the dose of .(1-10)×106 CAR positive T cells/kg. The cells perfusion process would last for 15min to 2 h via an ambulatory infusion pump. A single dose of 1.5 grams/m2 of cyclophosphamide will be given two days before CART cell infusion.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: TAI-GPC3-CART cells
A single dose of GPC3-CART cells will be administered by transcatheter arterial infusion(TAI) mediated as one dose infusion. The dose is 1-10x106/kg GPC3-CAR positive T cells. The infusion will be scheduled to occur 2 days after a single dose of 1.5 grams/m2 of cyclophosphamide. Patients will undergo cannula--DSA radiography--CAR-T cells perfused into hepatic artery. The cells perfusion process would last 15min to 2 h, and the specific time depends on patent's tumor-burdened state.
Drug: TAI-GPC3-CART cells
TAI 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
Other Names:
  • Gene modified patient T cells
