Recruit Status: Not yet recruiting
Study Type: Interventional
Official Title: A Multicenter Phase I/II Study for Relapsed or Refractory CD19+ B-acute Lymphoblastic Leukemia
Brief Summary: Evaluate the safety (P-I), pharmacokinetics and anti-tumor effect of immunotherapy of autologous T cells genetically modified to express anti-CD19 chimeric antigen receptor (CAR) (TBI-1501) for relapsed or refractory CD19+ B-cell acute lymphoblastic leukemia.
Detailed Summary:
Enroll patients after confirming eligibility. Following enrollment, peripheral blood mononuclear cells and blood plasma will be obtained from each subject by apheresis to start the manufacturing of TBI-1501.
Before TBI-1501 administration, it is necessary to pass the quality tests. Subject will be hospitalized from Day -3 to Day 28, and administered Cyclophosphamide (1,000 mg/m2/day×2 days) on Day -3 and Day -2.
