Evaluation of in Vitro Antitumor Activity of GD2 CAR-T Cells in Glioblastoma
Study Purpose
Glioblastoma is a brain tumor with a very poor prognosis, affecting around 2,400 new patients every year. Current treatments do not provide good control of the disease. In view of the therapeutic impasse, it is necessary to develop new strategies. CAR-T cells (Chimeric antigen receptor T cells) represent a highly promising therapy for the treatment of incurable cancers, including glioblastoma. This treatment aims to destroy cancer cells by relying on the patient's own immune system. CAR-T cells are generated from the patient's own immune cells, more specifically T lymphocytes, which are genetically modified to express a tumor-specific receptor on their surface. CAR-T cells bind to tumor cells and cause their destruction. However, these cells have shown limited therapeutic power in the treatment of brain tumors. This is mainly due to the microenvironment surrounding the tumor, which is composed of immunosuppressive cells. These cells, and the molecules they secrete, help to reduce the activity of CAR-T cells that would otherwise reach the tumor. Little is currently known about these resistance mechanisms. The aim of this research is therefore to better understand these resistance mechanisms in order to propose a strategy for enhancing the therapeutic action of CAR-T cells in the treatment of glioblastoma. The main objective of this research is to evaluate the impact of the tumor environment on the antitumor efficacy of anti-GD2 CAR-T therapeutic cells in an in vitro glioblastoma model. Both tumor environment cells and CAR-T therapeutic cells will be generated from glioblastoma patient cells. The secondary objectives of this research are to.
- - Evaluate the impact of tumor environment targeting on the in vitro antitumor efficacy of anti-GD2 CAR-T therapeutic cells.
- - Evaluate the quality/quantity of generated cells (CAR-T cells and tumor environment cells) in relation to glioblastoma patients.

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies. |

Trial ID:
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries. |
NCT06764537 |
|
Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
