Universal CAR-T Cells Targeting AML

Summary

The purpose of this clinical trial is to assess the feasibility, safety and efficacy of universal CAR T-cell products targeting CLL-1, CD33, CD38 and CD123 in patients with relapsed and refractory AML. The study also aims to learn more about the function of the universal CAR T cells and their persistency in AML patients.

4. Adequate bone marrow, liver and renal function as assessed by the following laboratory requirements: cardiac ejection fraction ≥ 50%, oxygen saturation ≥ 90%, creatinine ≤ 2.5 × upper limit of normal, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3 × upper limit of normal, total bilirubin ≤ 2.0mg/dL.
5. Hgb≥80g/L.
6. No cell separation contraindications.
7. Abilities to understand and the willingness to provide written informed consent.

Exclusion Criteria:

1. Sever illness or medical condition, which would not permit the patient to be managed according to the protocol, including active uncontrolled infection.
2. Active bacterial, fungal or viral infection not controlled by adequate treatment.
3. Known HIV or active hepatitis C virus (HCV) infection.
4. Pregnant or nursing women may not participate.
