Ages Eligible for Study:   2 Years and older   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No


  • Histologically confirmed diagnosis of CML blast phase
  • Ph chromosome-positive
  • Previous treatment with imatinib mesylate resulting in: i) Hematologic Resistance / Hematologic Refractory: Based on a physician's (documented) decision to discontinue imatinib mesylate treatment due to failure of continued benefit or no benefit to the patient, ii) Imatinib Mesylate Intolerance: any toxicity resulting in a physician's (documented) decision to discontinue imatinib mesylate treatment.
  • Patients must have recovered from the side effects of previous CML therapy for blast phase with the exception of hydroxyurea
  • Age >/= 2 years
  • Bilirubin </= 3 x the upper limit of normal (ULN), SGOT and SGPT </= 3 x ULN, except </= 5 x ULN in leukemic involvement of the liver, serum creatinine </= 2 x ULN
  • WHO performance status 0-3
  • A negative serum hCG pregnancy test in patients of childbearing potential
  • Able to give signed informed consent directly or through a parent or guardian for minors


  • Leukemic involvement of the central nervous system
  • Active malignancy other than CML or non-melanoma cancer of the skin
  • Previous treatment for CML with another investigational agent within 28 days of study entry
  • At study entry, patients who were treated with: imatinib mesylate within the past 48 hours, interferon-alpha within the past 48 hours; homoharringtonine within the past 14 days; low-dose cytosine arabinoside within 7 days, moderate dose within 14 days, or high dose within 28 days; etoposide, anthracyclines, or mitoxantrone within 21 days; busulfan within the past six weeks
  • Patients who had received hematopoietic stem cell transplantation within 6 weeks of Day 1 decitabine therapy
  • Patients with Grade 3/4 cardiac disease or any other serious concurrent medical condition.
  • Patients who are pregnant or nursing. All patients of childbearing potential must practice effective methods of contraception while on study.
  • Patients with mental illness or other condition precluding their ability to give informed consent or to comply with study requirements
  • Patients with systemic, uncontrolled infections
