Adult Acute Lymphoblastic Leukemia in Remission, B-cell Adult Acute Lymphoblastic Leukemia, B-cell Chronic Lymphocytic Leukemia, Hematopoietic/Lymphoid Cancer, Refractory Chronic Lymphocytic Leukemia
Conditions
Brief summary
This is a single-arm open-label phase I study to determine the effect of CD19- CAR-T Cells infusion followed by allogeneic stem cell transplantation in safety, efficacy and engraftment potential in patients with CD19+ B-lineage leukemia and lymphoma.
Detailed description
Primary objectives 1. To determine the safety and feasibility of allogeneic stem cell transplantation combined with adoptive transfer of T cells modified to express CD19-specific chimeric antigen receptor (CD19CAR) for treatment of leukemia and lymphoma Secondary objectives 2. To measure the efficacy of the CD19CAR T cell infusion combined with allogeneic stem cell transplantation
Interventions
Ex vivo-expanded autologous T cells modified to express CD19 CAR
Patients were given cyclophosphamide 500mg/m2/day on day -4 and fludarabine at 25 mg/m2/day on day -4, day -3, and day -2.
Patients were given cyclophosphamide 500mg/m2/day on day -4.
