Maintenance Azacitidine in Elderly Patients With Acute Myeloid Leukemia (AML) in CR After Induction Chemotherapy

Inclusion Criteria:

Histologic or cytologic confirmation of AML with greater than 20% blasts in bone marrow. All AML subtypes of the World Health Organization (WHO) classification will be included with the exception of promyelocytic leukemia and cytogenetics showing the (15;17) translocation or AML secondary to chemotherapy.
Achieved first morphologic complete remission (CR) or first morphologic complete remission with incomplete platelet recovery (CRp) after completion of induction chemotherapy using a standard induction regimen. Up to 2 induction cycles will be allowed. Confirmation of CR is defined as < 5% blasts in the bone marrow specimen, with a count of at least 100-200 nucleated cells and absence of Auer rods, along with peripheral blood neutrophil count >1.0 x 10^9/L and platelet count >100 x 10^9/L. Confirmation of CRp is defined as <5% blasts in the bone marrow specimen, with a count of at least 100-200 nucleated cells and absence of Auer rods, with incomplete platelet recovery (ANC ≥ 1000/µL and platelets 50-99,000/µL, along with transfusion-independence of red blood cells).
Received up to 2 cycles of any consolidation chemotherapy
Have an Eastern Cooperative Oncology Group (ECOG) performance status ≤2
Normal organ function at the time of screening: Total bilirubin ≤1.5 x upper limit of normal (ULN); aspartic transaminase (AST) and alanine transaminase (ALT) ≤2.5 x ULN; Serum creatinine ≤1.5 x ULN or creatinine clearance >60 mL/min for patients with creatinine levels above ULN
Men must agree to avoid fathering a child throughout the study.
Be capable of giving informed consent and have signed the informed consent form (ICF)

Exclusion Criteria:

Greater than 12 weeks since initiation of most recent cycle of consolidation chemotherapy
Women of childbearing potential
Prior relapse after complete remission for AML
AML secondary to previous exposure to cytotoxic chemotherapy known to induce leukemia
Active malignancy other than AML
Any diagnosis of metastatic disease
Have hepatic tumors
Radiation therapy, chemotherapy, or cytotoxic therapy, given to treat conditions other than AML <4 weeks prior to Day 1 or have not recovered from adverse events due to agents administered >4 weeks earlier
Known leukemic involvement of the central nervous system
Known or suspected hypersensitivity to azacitidine or mannitol
Prior or active disease that, in the opinion of the Investigator, may interfere with the procedures or evaluations to be conducted in the study (uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements)
Active viral infection with known human immunodeficiency virus (HIV) or viral hepatitis type B or C
Treatment with other investigational drugs within the 30 days prior to Day 1, or ongoing adverse events from previous treatment with investigational drugs, regardless of the time period
Any prior treatment with azacitidine or decitabine
