Brief 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.

Condition or disease Intervention/treatment Phase
Acute Myeloid Leukemia Biological: Muc1/CLL1/CD33/CD38/CD56/CD123-specific gene-engineered T cells Phase 1 Phase 2

Detailed Description:

Acute myeloid leukemia (AML) is a malignant disease characterized by the rapid growth of myeloblasts that build up in the bone marrow and interfere with the production of normal blood cells.

In this study, the patients' own T cells will be genetically modified with lentiviral vectors expressing chimeric antigen receptors. The multi-CAR T cells recognize specific molecules such as CD33, CD38, CD123, CD56, MucI, and CLL1, which are often found expressed on the surface of AML cells. The engineered CAR T cells will be infused into patients.

The purpose of this clinical study is to assess the feasibility, safety and efficacy of the multi-CAR T cell therapy against 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.
