IMPACT-AML: Randomized Pragmatic Clinical Trial for Relapsed or Refractory AML

Summary

The primary objective is to evaluate the efficacy and toxicity of high versus low intensity therapy options in patients with refractory forms and early relapses of acute myeloid leukemia (R/R AML) who are scheduled for allogeneic hematopoietic stem cell transplantation (alloHSCT).

Exclusion Criteria:
