Multi-CAR T Cell Therapy for Acute Myeloid Leukemia

Summary

The purpose of this clinical trial is to assess the feasibility, safety and efficacy of multi-CAR T cell therapy targeting different AML surface antigens in patients with relapsed or refractory acute myeloid leukemia (AML). Another goal of the study is to learn more about the function of the multi-CAR T cells and their persistency in the patients.
