Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

CD19 CAR-T CELLS

A conditioning chemotherapy regiment of fludarabine and cyclophosphamide will be administered followed by a single infusion of CAR transduced autologous T cells administered intravenously.

Group Type EXPERIMENTAL

CD19 CAR-T CELLS

Intervention Type BIOLOGICAL

CD19 CAR-T cells will be administered after completion of the lymphodepletion chemotherapy.

Cyclophosphamide
