Brief Summary

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

This is a prospective,open-label, single center and single arm phase 1/2 study to evaluate the efficacy and safety of T cells expressing humanized CD7 chimeric antigen receptors treatment for patients with refractory/relapsed CD7 positive acute 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 CAR T-cells targeting CD7 to confirm the safety and efficacy of CD7 CAR T-Cells in CD7+ relapsed or refractory acute leukemia.
