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.

Condition or disease Intervention/treatment Phase
B-cell Adult Acute Lymphoblastic Leukemia B-cell Chronic Lymphocytic Leukemia Adult Acute Lymphoblastic Leukemia in Remission Hematopoietic/Lymphoid Cancer Refractory Chronic Lymphocytic Leukemia Biological: anti-CD19 CAR-T Drug: Fludarabine Drug: Cyclophosphamide Phase 1

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
