NCT02250937

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.

Outcome Measures

Primary Outcomes (2)

  • Progression free survival

    The method of Kaplan and Meier will be used to estimate distribution of progression free survival.

    At 6 months

  • Disease free survival (DFS)

    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.

    Up to 2.5 years

Secondary Outcomes (8)

  • Incidence of toxicity of these regimens

    Up to 2.5 years

  • Cumulative incidence of acute graft versus host disease (GVHD)

    Up to 2.5 years

  • Cumulative incidence of chronic GVHD

    Up to 2.5 years

  • Overall survival

    Up to 2.5 years

  • Time to neutrophil engraftment

    Up to 2.5 years

  • +3 more secondary outcomes

Study Arms (2)

Arm I (busulfan days -13 and -12 before PBSCT)

EXPERIMENTAL

PREPARATIVE REGIMEN: Patients receive venetoclax PO QD on days -22 to -3 and busulfan 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. TRANSPLANT: Patients undergo allogeneic PBSCT on day 0.
