Relapsed and/or Refractory CD33+ AML
Conditions
Keywords
CART, AML
Brief summary
The purpose of this study is to evaluate the safety and efficiency of allogeneic cluster of differentiation 33 (CD33)-directed chimeric antigen receptor modified T cells (CART-33) infusions in patients with relapsed / refractory acute myeloid leukemia (AML).
Detailed description
The relapsed and/or refractory AML patients will receive infusions of allogeneic CART-33 within 1 week after chemotherapy. The re-induction chemotherapy regimen was primarily idarubicin and cytarabine, and no graft-versus-host disease (GVHD) prevention was conducted pre- and post- therapy.
