Conditions
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.
TERTIARY OBJECTIVES:
I. To study chemotherapy resistance. II. To study deoxyribonucleic acid (DNA) damage. III. To study immune recovery and cytokines (both in plasma and cells). IV. To study BCL-2 family expression, stem cell surface markers and intracellular signaling markers in AML cells at the time of relapse.
OUTLINE:
PREPARATIVE REGIMEN: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive venetoclax orally (PO) once daily (QD) on days -22 to -3 and busulfan intravenously (IV) over 3 hours on days -13 and -12. Patients then receive fludarabine phosphate IV over 1 hour, cladribine IV over 2 hours, and busulfan IV over 3 hours on days -6 to -3.
ARM II: Patients receive venetoclax PO QD on days -22 to -3 and busulfan IV over 3 hours on days -20 and -13. Patients then receive fludarabine phosphate IV over 1 hour, cladribine IV over 2 hours, and busulfan IV over 3 hours on days -6 to -3.
TRANSPLANT: Patients undergo allogeneic peripheral blood stem cell transplant (PBSCT) on day 0.
After completion of study treatment, patients are followed up for 2.5 years.
