Study Overview
Brief Summary
This randomized phase II trial studies how well venetoclax and sequential busulfan, cladribine, and fludarabine phosphate before donor stem cell transplant work in treating patients with acute myelogenous leukemia or myelodysplastic syndrome. Giving chemotherapy before a donor peripheral blood stem cell transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. When the healthy stem cells from a donor are infused into a patient, they may help the patient's bone marrow make more healthy cells and platelets and may help destroy any remaining cancer cells.
Detailed Description
PRIMARY OBJECTIVE:
I. To compare progression free survival of two schedules of venetoclax, timed sequential busulfan, cladribine and fludarabine conditioning regimen in patients with acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS).
SECONDARY OBJECTIVES:
I. Compare overall survival between the two schedules. II. Compare non relapse mortality between the two schedules. III. Compare neutrophil and platelet engraftment between the two schedules. IV. Compare acute and chronic graft-versus-host disease (GVHD) between the two schedules.
V. Compare cumulative incidence of relapse between the two schedules. VI. Compare grade III/IV toxicity between the two schedules.

Outcomes
Primary Outcomes
Progression free survival
Time Frame: At 6 months
The method of Kaplan and Meier will be used to estimate distribution of progression free survival.
Disease free survival (DFS)
Time Frame: Up to 2.5 years
Will test whether there is strong evidence that DFS differs between the two arms using a stratified log-rank test. Will use the Lan-DeMets alpha spending approach with an O'Brien-Fleming stopping boundary to compare the two arms.

- Time to platelet engraftment(Up to 2.5 years)
