Brief summary
A Study of NKG2D CAR-T Cell Therapy for Patients With Relapsed and/or Refractory Acute Myeloid Leukemia.
Detailed description
This is a single arm, open-label, single-center study. This study is indicated for relapsed or refractory NKG2D ligand positive acute myeloid leukemia. The selections of dose levels and the number of subjects are based on clinical trials of similar foreign products. 36 patients will be enrolled. Primary objective is to explore the safety,main consideration is dose-related safety.
Interventions
DRUGNKG2D CAR T-cells
Each subject receive NKG2D CAR T-cells by intravenous infusion
