NCT05063682

Brief Summary

This phase I trial investigates the efficacy and safety of brain-targeting epidermal growth factor receptor chimeric antigen receptor immune cells (EGFRvIII-CAR T cells) in treating patients with leptomeningeal disease from glioblastoma. T cells are part of the immune system and help the body fight malignant tumours. Immune cells can be genetically modified to destroy brain tumor cells in the laboratory. EGFRvIII -CAR T cells are brain tumor specific and can enter and express its genes in immune cells. Administering patients EGFRvIII -CAR T cells may help to recognize and destroy brain tumor cells in patients with leptomeningeal disease from glioblastoma.

Study Arms (1)

Treatment

EXPERIMENTAL

Patients receive EGFRvIII -CAR T cells intracerebroventricular over 15 minutes on day 1. Patients may receive additional cycles based on the persistence of the cells.

Biological: EGFRvIII-specific hinge-optimized CD3 ζ-stimulatory/41BB-co-stimulatory Chimeric Antigen Receptor autologous T-lymphocytes
