Clinical Trial Summary

A Study of IL3 CAR-T Cell Therapy for Patients With CD123 Positive Relapsed and/or Refractory Acute Myeloid Leukemia.

Description:

This is a single arm, open-label, single-center study. This study is indicated for relapsed or refractory CD123+ acute myeloid leukemia. The selections of dose levels and the number of subjects are based on clinical trials of similar foreign products. 36 patients will be enrolled. Primary objective is to explore the safety, main consideration is dose-related safety.
