I. Determine the safety and toxicity of MS-275 and azacitidine in patients with myelodysplastic syndromes, chronic myelomonocytic leukemia, or acute myeloid leukemia.
II. Determine the maximum tolerated dose and optimal phase II dose of MS-275 when combined with azacitidine in these patients.
III. Determine, preliminarily, the potential therapeutic activity of this regimen in these patients.
IV. Correlate MS-275 pharmacokinetics with clinical response and laboratory correlative endpoints in patients treated with this regimen.
OUTLINE: This is a multicenter, dose-escalation study of MS-275. Patients receive azacitidine subcutaneously on days 1-10 and oral MS-275 on days 3 and 10.
Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of MS-275 until the maximum tolerated dose (MTD) is determined. Patients receive adjusted doses of azacitidine based on clinical response. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Up to 9 additional patients are treated at the MTD.
[Note: Patients who do not achieve hematologic improvement or partial or complete response but who have stable disease after 4 courses of therapy may receive an additional 4 courses of therapy at a higher dose than what was originally assigned]

Experimental: Arm I
Patients receive azacitidine subcutaneously on days 1-10 and oral MS-275 on days 3 and 10. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses* of MS-275 until the maximum tolerated dose (MTD) is determined. Patients receive adjusted doses of azacitidine based on clinical response. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Up to 9 additional patients are treated at the MTD.
- Maximum tolerated dose of MS-275 in combination with 5-azacitidine, assessed using Common Toxicity Criteria version 3.0 [ Time Frame: 4 weeks ]
- Response rate measured by IWG criteria [ Time Frame: 16 weeks ]
- Optimal dose combination [ Time Frame: At study completion ]
- Levels of histone acetylation and gene re-expression [ Time Frame: 4 weeks ]
