This randomized phase II trial is studying azacitidine and entinostat to see how well they work compared to azacitidine alone in treating patients with myelodysplastic syndromes, chronic myelomonocytic leukemia, or acute myeloid leukemia. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Entinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving azacitidine together with entinostat may kill more cancer cells
Further Study Information
I. Compare the overall response rate (complete, partial, and hematologic improvement-major by International Working Group [IWG] criteria) in patients with treatment-induced or non-treatment-induced myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia (dysplastic), or acute myeloid leukemia with multilineage dysplasia treated with azacitidine with vs without entinostat.
II. Compare the major response rate (complete and partial responses by IWG criteria) in patients treated with these regimens.
I. Evaluate the toxicity of azacitidine and entinostatin these patients. II. Identify changes in gene promoter methylation and gene expression that may be associated with response to azacitidine and entinostat.
III. Identify other molecular mechanisms (such as DNA damage) that may be associated with response to azacitidine and entinostat.
OUTLINE: This is a randomized, multicenter study. Patients are first stratified according to treatment-related disease (yes vs no), followed by a second stratification according to disease (myelodysplastic syndromes [MDS] high/intermediate-2 vs MDS low/intermediate-1 vs chronic myelomonocytic leukemia vs acute myeloid leukemia with multilineage dysplasia). Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive azacitidine subcutaneously once daily on days 1-10.
ARM II: Patients receive azacitidine as in arm I and oral entinostat on days 3 and 10.
Treatment in both arms repeats every 28 days for at least 6 and up to 24 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed periodically for 5 years.
