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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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
