Interventions

CD19 CAR engineered autologous T-cellsBIOLOGICAL
Given IV Following preconditioning with lymphodepleting chemotherapy (cyclophosphamide and fludarabine) patients will be treated with CD19 Chimeric Antigen Receptor (CAR) T cells as a single or split dose (day 0, 1 and 2, CAR cells will be intravenously infused at the 10%, 30% and 60% ratio respectively). Dosing of CD19 CAR-T cells will follow a dose-escalation schema, with dose changes based on dose-limiting toxicities.
