A-CAR028, Acute Myeloid Leukemia
Brief summary
This is a single-center, open-label study to evaluate the safety and efficacy of A-CAR028 in relapsed/refractory acute myeloid leukemia patients
Detailed description
The study includes the following sequential phases: Screening, Apheresis and A-CAR028 manufacturing, Baseline testing, Lymphodepletion, A-CAR028 infusion, Dose-limiting toxicity observation and Follow-up Visit
Interventions
A-CAR028 is a novel 2nd generation 4-1BB bispecific chimeric antigen receptor T-cell (CAR-T) targeting both CD33 and CLL-1 antigens
