Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a single center, open-label phase 1/2 study to evaluate the safety and efficacy of anti-CLL1 chimeric antigen receptor engineered T cell immunotherapy (CART) in the treatment of CLL1 positive relapsed or refractory acute myeloid leukemia.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The patients will receive infusion of anti-CLL1 CAR T-cells to confirm the safety and efficacy of anti-CLL1 CAR T-cells in relapsed or refractory acute myeloid leukemia.
