  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:
  • To determine the 1 year relapse free survival (RFS) for individuals > 55 years in age with AML CR (or PR) who undergo a 7-8/8 HLA- matched unrelated donor transplant using a reduced intensity regimen. [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To determine the risk of transplant related mortality, acute and chronic GVHD, RFS (at 1 year) and overall survival for patients > 55 years in age with AML undergoing full or reduced transplant with the best available donor. [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 40
Study Start Date: March 2007
Estimated Study Completion Date: March 2015
Estimated Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: CR
Patients in CR will receive a reduced intensity transplant regimen consisting of Fludarabine plus Busulfan (FluBu2).
Drug: Fludarabine, Busulfan (FluBu2)
Fludarabine (40 mg/m2/day x 4 days) plus Busulfan (3.2 mg/m2/day x 2 days)
Radiation: total body irradiation
Patients on the FluBu2 arm who receive a mismatched allograft (7/8 HLA match) will additionally receive 200 cGy of total body irradiation (TBI) pre-transplant.
Procedure: stem cell transplant
Allogeneic stem cell transplant from related or unrelated donor
Experimental: PR
Patients in PR will receive a full intensity transplant regimen consisting of Fludarabine plus Busulfan (FluBu4).
Drug: Fludarabine, Busulfan (FluBu4)
Fludarabine (40 mg/m2/day x 4 days) plus Busulfan (3.2 mg/m2/day x 4 days).
Procedure: stem cell transplant
Allogeneic stem cell transplant from related or unrelated donor
