This is a 2 part study. The goal of the first part of this clinical research study is to find the highest tolerable dose of azacitidine that can be given with a TKI that you are already taking (such as Gleevec, Sprycel, or Tasigna). The safety of this drug will also be studied. The goal of the second part is to see if this combination may improve your response to the TKI you are already taking.
Azacitidine is designed to change genes that are thought to cause leukemia. By changing these genes, the drug may help to stop them from causing the disease to grow.

|Estimated Study Completion Date :||August 2019|
Experimental: Dose Escalation Group (AZA)
Azacitidine (AZA) starting dose 50 mg/m2 a day for 3 days subcutaneous or intravenous of 28 day cycle. TKI at dose received during last 6 months.
Drug: Azacitidine (AZA)
Starting Dose 50 mg/m2 by subcutaneous or by vein for 3 days of a 28 day cycle.
Other Names:Drug: Tyrosine kinase inhibitor (TKI)
Continuation of dose already receiving during previous 6 months.
Experimental: Expansion Group (AZA MTD)
Dose Escalation Group plus additional 36 participants for Azacitidine 75 mg/m2 (or Phase I MTD) either subcutaneous or intravenous every day for 3 days of 28 day cycle. TKI at dose received during last 6 months.
Drug: Tyrosine kinase inhibitor (TKI)
Continuation of dose already receiving during previous 6 months.Drug: Azacitidine
75 mg/m2 daily for 3 days, unless MTD defined at lower dose level in Phase I then that would become dose used for Phase II.
- Maximum Tolerated Dose (MTD) of Azacitidine [ Time Frame: First 28 day cycle ]MTD is defined as the highest dose level in which 6 patients have been treated and one or fewer patient experiences Dose-Limiting Toxicity (DLT) within the first course of treatment.
- Number of Participants with Decrease of Transcript Levels by at Least One Log (or Undetectable Transcript Level) Within 12 Months [ Time Frame: Baseline to 12 months ]Participants with response defined as a greater than a one-log reduction of BCR-ABL transcript levels from the baseline level at the time vaccination was initiated, or a disappearance of BCR-ABL transcripts (i.e., complete molecular response) within 12 months.
