Administration of CD19/BCMA Targeted CAR T-cells and dasatinib
Administration of CD19/BCMA Targeted CAR T-cells
Dose levels of CAR-T cells are based on clinical trials of similar foreign products. Meanwhile, dasatinib would be combined as the following regimens: 1) Dasatinib preconditioning CAR-T cells during the manufacturing; 2) Dasatinib for the intervention of cytokine release storm after CAR-T cell infusion; 3) Dasatinib for the intervention of neurotoxicities after CAR-T cell infusion; 4) Dasatinib for the phase of CAR-T cell decreasing.
