Official Title: Phase II Study of the Addition of Azacitidine (NSC#102816) to Reduced-Intensity Conditioning Allogeneic Transplantation for Myelodysplasia (MDS) and Older Patients With AML

Brief Summary: This phase II clinical trial is studying how well giving busulfan, fludarabine phosphate, and anti-thymocyte globulin followed by donor stem cell transplant and azacitidine works in treating patients with high-risk myelodysplastic syndrome and older patients with acute myeloid leukemia. Giving low doses of chemotherapy, such as busulfan and fludarabine phosphate, before a donor stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-vs-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving anti-thymocyte globulin before transplant and giving azacitidine, tacrolimus, and methotrexate after the transplant may stop this from happening.

Detailed Summary:

PRIMARY OBJECTIVE:

I. To determine if this treatment can improve 2-year progression-free survival (PFS) in patients with high risk myelodysplastic syndrome (MDS) and in patients with acute myeloid leukemia (AML) >= 60 yrs age

SECONDARY OBJECTIVES:

I. To determine the safety and feasibility of using post-transplantation azacitidine.

II. To determine the ability to use pharmacokinetic-directed busulfan to achieve area under the curve (AUC) within 20% of target AUC in > 80% of patients.

III. To determine the rate of grade II-IV and III-IV acute graft-vs-host disease (GVHD).

IV. To determine the incidence of extensive chronic GVHD. V. To determine treatment-related mortality at 100 days and at 1 year. VI. To determine 5-year overall survival.

OUTLINE:

REDUCED-INTENSITY CONDITIONING: Patients receive fludarabine phosphate intravenously (IV) over 30 minutes on days -7 to -3, busulfan IV over 45 minutes on days -6 to -3, and anti-thymocyte globulin IV over 4-10 hours on days -6 to -5 (matched sibling donor [MSD]) or -6 to -4 (matched unrelated donor [MUD]).

TRANSPLANTATION: Patients undergo allogeneic hematopoietic stem cell transplantation on day 0 or on days 0-1.

GRAFT-VS-HOST DISEASE PROPHYLAXIS: Patients receive tacrolimus orally (PO) or IV on days -2 to 90 with taper on days 150-180. Patients also receive methotrexate IV on days 1, 3, 6 (MSD), and 11 (MUD).

Current Primary Outcome: Progression-free survival [ Time Frame: At 2 years ]

Will be estimated using the Kaplan-Meier product limit estimator.


Original Primary Outcome: Progression-free survival

Current Secondary Outcome:

  • Overall survival (OS) [ Time Frame: Up to 5 years ]
    Estimated using the Kaplan-Meier product limit estimator.
  • Treatment related mortality (TRM) [ Time Frame: Up to 6 months post-treatment ]
    TRM is defined as death within the first six months after transplant not secondary to relapse.


Original Secondary Outcome:

  • Safety
  • Graft-vs-host disease
  • 5-year overall survival
