Summary

This study tests a reduced-intensity chemotherapy combination (fludarabine and treosulfan) before a half-matched stem cell transplant in 77 older or frail adults with AML. The goal is to see if this gentler regimen can control the leukemia long-term while being safe enough for patients who cannot tolerate standard high-dose chemo. Participants will receive the transplant and then be followed for relapse and side effects.
