Primary purpose: TREATMENT

Brief summary: To determine the safety and efficacy of decitabine in patients with Philadelphia chromosome-positive chronic myelogenous leukemia blastic phase that were previously treated with imatinib mesylate (STI 571) and became resistant/refractory or were found to be intolerant to the drug.


Eligibility criteria: Inclusion:

* 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

Exclusion:

* 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
