  Purpose

The prognosis for older individuals with acute myelogenous leukemia (AML) has been historically poor, with 2 year disease-free survival rates < 20% reported. Younger patients with AML in first complete remission are routinely treated using a full intensity (myelo-ablative) chemotherapy followed by a blood stem cell transplant. For the older patient with AML, full intensity therapy transplants have been greatly limited by increased rates of toxic effects related to this type of conditioning regimen. Reduced intensity (non-myeloablative) conditioning regimens have been used in a number of clinical settings, including AML therapy, to lessen the regimen related toxicity in the older patient. Recent data from the University of Michigan Blood and Marrow Transplant Program suggests improved survival for individuals > 55 years in age undergoing reduced intensity, transplants from unrelated donors. This study will investigate the safety and efficacy of this treatment option for older patients with AML, with the primary goal being to improve the survival and lifespan for older patients with AML.

Primary Outcome Measures:
  • Percentage of Participants With Relapse Free Survival at 1 Year [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    The primary objective was to determine the 1 year relapse free survival rate (RFS) for individuals > 55 years in age with Acute myeloid leukemia (AML), and Complete Remission (CR) or Partial Remission (PR) who undergo a 7-8/8 HLA- matched unrelated donor transplant using a reduced intensity regimen.


Secondary Outcome Measures:
  • Percentage of Participants Alive at 1 Year [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
    One of the secondary objectives was to determine overall survival for patients > 55 years in age with AML undergoing full or reduced transplant with the best available donor.

Arms Assigned Interventions
Experimental: Fludarabine plus Busulfan (CR)
Patients in CR will receive a reduced intensity transplant regimen consisting of Fludarabine plus Busulfan (FluBu2).
Drug: Fludarabine

Experimental: Fludarabine plus Busulfan (PR)
Patients in PR will receive a full intensity transplant regimen consisting of Fludarabine plus Busulfan (FluBu4).
Drug: Fludarabine
Fludarabine (40 mg/m2/day x 4 days)
Drug: Busulfan
Busulfan (3.2 mg/m2/day x 2 days or x 4 days).
Procedure: Stem Cell Transplant
Allogeneic stem cell transplant from related or unrelated donor
