Tris-CAR-T Cell Therapy for Recurrent Glioblastoma

"Intratumoral or intraventricular administration via Ommaya reservoir.~Dose level 0: 1×10\^7 autologous Tris-CAR-T cells, at least one dose, maximum 6 doses, 2 patients.~Dose level 1: 1×10\^8/ 5×10\^6 autologous Tris-CAR-T cells, at least one dose, maximum 6 doses, 2 patients. The dose of Dose level 1 will refer to the adverse effect of Dose level 0. When dose-related side effects occurred in 2 patients in the Dose level 0, the dose should be reduced to 5×10\^6 cells.~In Dose levels 0 and 1, the second dose will be infused 28 days after the first dose, and the subsequent doses will be administered weekly.~Dose level 2: 5×10\^7 autologous Tris-CAR-T cells, weekly administered, maximum 8 weeks, 4 patients. If the results of Dose levels 0 and 1 suggested that dose-related toxic side effects could have occurred in the 1×10\^7cells dose, the researcher would re-determine the dosage of the multidose clinical exploration study."
