Brief Summary:
This randomized phase III trial studies clofarabine to see how well it works compared with daunorubicin hydrochloride and cytarabine when followed by decitabine or observation in treating older patients with newly diagnosed acute myeloid leukemia. Drugs used in chemotherapy, such as clofarabine, daunorubicin hydrochloride, cytarabine, and decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. It is not yet known which chemotherapy regimen is more effective in treating acute myeloid leukemia.

Primary Outcome Measures :
  1. Overall Survival [ Time Frame: Assessed every 3 months for 4 years and then every 6 months for 1 year ]
    Overall survival is defined as the time from randomization to death or date last known alive.


Secondary Outcome Measures :
  1. Proportion of Patients With Complete Remission [ Time Frame: Assessed every 3 months for 4 years and then every 6 months for 1 year ]

    Patients are required to have all of the following to be considered as having a completion remission (CR).

    • Peripheral Blood Counts

      1. Neutrophil count > 1.0 x 10^9 /L
      2. Platelet count ≥ 100 x 10^9 /L
      3. Reduced hemoglobin concentration or hematocrit has no bearing on remission status
      4. Leukemic blasts must not be present in the peripheral blood
    • Bone Marrow Aspirate and Biopsy

      1. Cellularity of bone marrow biopsy must be > 20% with maturation of all cell lines
      2. < 5% blasts by morphologic review
      3. Auer rods must not be detectable
    • Extramedullary leukemia, such as CNS or soft tissue involvement, must not be present

  2. Overall Survival by Donor Status [ Time Frame: Assessed every 3 months for 4 years and then every 6 months for 1 year ]
    Overall survival is defined as time between achieving leukemia-free state after induction therapy to death from any cause or date last known alive. The association between overall survival and donor status was evaluated regardless of assigned treatment arms. Patients with transplant donor information (either had donor or did not have a donor) reported after achieving CR/Cri/leukemia-free state post induction therapy were included in this analysis.

  3. Disease-free Survival for Maintenance [ Time Frame: Assessed every 3 months for 4 years and then every 6 months for 1 year ]
    DFS for maintenance comparison is defined as the time from maintenance randomization until relapse or death of any cause. The censored follow-up time for patients without relapse and death information is the date of last contact. Only patients who remained in CR or CRi after completion of consolidation therapy that were randomized to either observation or decitabine in the maintenance Step were included in this analysis.


Other Outcome Measures:
  1. Expression and Methylation Profiling [ Time Frame: Baseline of maintenance treatment ]
    DNA methylation profiling and gene expression are evaluated using peripheral blood samples collected at baseline of the maintenance treatment (prior to 2nd randomization). These are to be compared between patients with decitabine and patients on observation.

  2. Relapse After Decitabine Maintenance by Epigenetic Signature of Normal Bone Marrow [ Time Frame: Assessed every 3 months for 4 years and then every 6 months for 1 year ]

    To examine the epigenetic profiles of remission marrow among patients randomized to observation vs. decitabine to determine whether epigenetic signature of apparently morphologically normal bone marrow is predictive of relapse or response to decitabine maintenance.

    Relapse following complete remission is defined as:

    1. Peripheral Blood Counts

      • Reappearance of blasts in the blood
    2. Bone Marrow Aspirate and Biopsy

      • Presence of > 5% blasts, not attributable to another cause (e.g., bone marrow regeneration).
      • If there are no circulating blasts and the bone marrow contains 5% to 20% blasts, then a repeat bone marrow performed ≥ 1 week later documenting more than 5% blasts is necessary to meet the criteria for relapse.

  3. Complete Remission Rate by ABC-transporter P-glycoprotein (Pgp) [ Time Frame: Assessed every 3 months for 4 years and then every 6 months for 1 year ]

    Patients with all the following are considered as having a complete remission.

    • Peripheral Blood Counts

      1. Neutrophil count > 1.0 x 109 /L
      2. Platelet count ≥ 100 x 109 /L
      3. Reduced hemoglobin concentration or hematocrit has no bearing on remission status
      4. Leukemic blasts must not be present in the peripheral blood
    • Bone Marrow Aspirate and Biopsy

      1. Cellularity of bone marrow biopsy must be > 20% with maturation of all cell lines
      2. < 5% blasts by morphologic review
      3. Auer rods must not be detectable
    • Extramedullary leukemia, such as CNS or soft tissue involvement, must not be present

    The proportion of patients with complete remission will be compared between patients who overexpress Pgp and patients who do not overexpress Pgp.


  4. To Assess the Intensity of Expression of CXCR4 on Diagnostic Leukemia Cells and to Correlate This Parameter With Other Established Prognostic Factors [ Time Frame: Baseline ]
    Expression of CXCR4 will be assessed in this study by flow cytometric assay. The associations between the expression level and other prognostic factors in patients receiving induction treatment will be evaluated.

  5. The Association Between Somatic Mutations and Relapse [ Time Frame: Assessed every 3 months for 4 years and then every 6 months for 1 year ]

    Relapse following complete remission is defined as:

    1. Peripheral Blood Counts

      • Reappearance of blasts in the blood
    2. Bone Marrow Aspirate and Biopsy

      • Presence of > 5% blasts, not attributable to another cause (e.g., bone marrow regeneration).
      • If there are no circulating blasts and the bone marrow contains 5% to 20% blasts, then a repeat bone marrow performed ≥ 1 week later documenting more than 5% blasts is necessary to meet the criteria for relapse.

  6. Overall Survival by Patient Characteristics and Lifestyle [ Time Frame: Assessed every 3 months for 4 years and then every 6 months for 1 year ]
    Overall survival is defined as time from randomization to death or date last known alive. The associations between overall survival and smoking status, obesity, regular acetaminophen use, regular aspirin use, benzene exposure, living in a rural/farm environment and some other underlying exposures and lifestyle factors will be evaluated.

  7. Copy Number Changes Using Array Comparative Genomic Hybridization (CGH) by Patient Characteristics [ Time Frame: Baseline ]
    Copy number changes will be tested based on array CGH technology. The associations between copy number changes and acute myeloid leukemia patient characteristics will be evaluated.

  8. Quality of Life (QOL) Assessed by Functional Assessment of Cancer Therapy - Leukemia (FACT-Leu) [ Time Frame: Assessed at baseline, 14 days after 1st induction treatment, prior to consolidation therapy (day 35-36), prior to maintenance treatment, end of maintenance treatment ]
    QOL will be assessed using the Functional Assessment of Cancer Therapy - Leukemia (FACT-Leu). This instrument combines the General version of the Functional Assessment of Cancer Therapy (FACT-G) with a leukemia-specific subscale. The total score of FACT-Leu ranges between 0 and 176. Higher score indicates better QOL.

  9. Change in Health-related QOL Over Time [ Time Frame: Assessed at baseline, 14 days after 1st induction treatment, prior to consolidation therapy (day 35-36), prior to maintenance treatment, end of maintenance treatment ]

    QOL will be assessed using the Functional Assessment of Cancer Therapy - Leukemia (FACT-Leu). This instrument combines the General version of the Functional Assessment of Cancer Therapy (FACT-G) with a leukemia-specific subscale. The total score of FACT-Leu ranges between 0 and 176. Higher score indicates better QOL.

    Changes in QOL will be calculated by subtracting baseline QOL score from follow-up QOL score.


  10. Patient Function Assessed by Functional Assessment of Cancer Therapy - General (FACT-G) [ Time Frame: Assessed at baseline ]
    QOL will be assessed using the Functional Assessment of Cancer Therapy - General (FACT-G). FACT-G includes 4 subscales, physical well-being (score range: 0-28), social/family well-being (score range: 0-28), emotional well-being (score range: 0-24), and functional well-being (score range: 0-28). The total score of FACT-G ranges between 0 and 108. Higher score indicates better QOL.

  11. Change in QOL Post Transplant From Baseline [ Time Frame: Assessed prior to transplant and 100 days after transplant ]

    For those patients who go to allo transplant, the FACT-Leu and the Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-Fatigue) instruments will be administered at the beginning of the conditioning regimen and 100 days (+14 days) post transplant.

    FACT-Leu combines the General version of the Functional Assessment of Cancer Therapy (FACT-G) with a leukemia-specific subscale. The total score of FACT-Leu ranges between 0 and 176. Higher score indicates better QOL.

    FACIT-Fatigue has 13 items and the total score ranges between 0 and 52. Higher score indicates better QOL.

    Changes in QOL will be calculated by subtracting baseline QOL score from follow-up QOL score.


  12. Baseline QOL Scores by Treatment Completion Status [ Time Frame: Assessed at baseline ]

    The associations between baseline QOL scores and the ability to finish treatment will be evaluated. Baseline QOL will be assessed using the Functional Assessment of Cancer Therapy - Leukemia (FACT-Leu) and the Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-Fatigue).

    FACT-Leu combines the General version of the Functional Assessment of Cancer Therapy (FACT-G) with a leukemia-specific subscale. The total score of FACT-Leu ranges between 0 and 176. Higher score indicates better QOL.

    FACIT-Fatigue has 13 items and the total score ranges between 0 and 52. Higher score indicates better QOL.
