Acute Myeloid Leukemia, Adult Acute Megakaryoblastic Leukemia, Adult Acute Monoblastic Leukemia
About this trial
This is an interventional treatment trial for Acute Myeloid Leukemia
Eligibility Criteria
Inclusion Criteria:
Meets one of the following sets of criteria:
Myelodysplastic syndromes (MDS):
Disease with high-risk features (found either at diagnosis or before initiation of cytotoxic therapy), defined as one of the following:
- International prognostic scoring system (IPSS) risk >= intermediate-2
- Refractory anemia with excess blasts by French-American-British (FAB) classification
- High-risk cytogenetics (either complex or -7)
- Less than 10% bone marrow blasts as determined by bone marrow biopsy within the past 4 weeks (reduction in marrow blast percentage may be achieved with chemotherapy or other therapy)
- Less than 75 years old
Acute myeloid leukemia (AML):
- No FAB M3
- No acute leukemia following blast transformation of prior chronic myelogenous leukemia or other myeloproliferative disease
- Patients with preceding MDS or treatment-related AML are eligible
- Prior central nervous system (CNS) involvement is allowed provided the disease is in remission at transplantation
Morphologic complete remission (leukemia-free state) is defined as meeting all of the following criteria:
- Bone marrow blasts < 5% (as determined by bone marrow within the past 4 weeks), but without requirement for normal peripheral blood counts
- No extramedullary leukemia
- No blasts in peripheral blood
Achieved complete remission (CR) after no more than 2 courses of induction chemotherapy
- Patients treated with azacitidine or decitabine who achieve a leukemia-free state are eligible (may have required up to 4 courses of therapy to reach this status)
- Age 60 to 74 years
Donors must meet the following criteria:
One of the following:
- HLA-identical sibling (6/6) by serologic typing for class (A, B) and low-resolution molecular typing for class II (DRB1)
- Matched unrelated donor (8/8) by high-resolution molecular typing at HLA-A, -B, -C, and DRB1
- No syngeneic donors
- Eastern Cooperative Oncology Group (ECOG) performance status 0-2
- Calculated creatinine clearance ≥ 40 mL/min
- Bilirubin < 2 mg/dL OR bilirubin 2-3 mg/dL provided direct bilirubin is normal
- Aspartate aminotransferase (AST) < 3 times upper limit of normal
- Diffusing capacity of the lung for carbon monoxide (DLCO) > 40% with no symptomatic pulmonary disease
- Left ventricle ejection fraction (LVEF) >= 30% by echocardiogram (ECHO) or multigated acquisition (MUGA)
- Not pregnant or nursing
- Negative pregnancy test
- Fertile patients must use effective contraception
- No uncontrolled diabetes mellitus or active serious infections
- No known hypersensitivity to E. coli-derived products, azacitidine, or mannitol
- No human immunodeficiency virus (HIV) infection or active hepatitis B or C
Prior azacitidine or decitabine allowed
- No patients who progressed from MDS to AML during treatment with azacitidine or decitabine
- At least 4 weeks since prior deoxyribonucleic acid (DNA)-hypomethylating chemotherapy, radiotherapy, and/or surgery
No more than 2 courses of consolidation therapy before transplantation (for patients with AML)
- Any consolidation regimen that does not require transplantation can be used
- No more than 6 months from documentation of morphologic CR to transplantation

Arms of the Study
Arm 1
Experimental
Treatment (chemotherapy and transplant)
REDUCED-INTENSITY CONDITIONING: Patients receive fludarabine phosphate 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 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). CONSOLIDATION: Beginning on day 42, patients receive azacitidine SC or IV on days 1.
