This study is designed to examine blood levels of ASTX727, a fixed-dose combination tablet
containing the combination of cedazuridine (100 mg) and decitabine (35 mg), when given under
fed versus fasted conditions to participants with myelodysplastic syndromes (MDS), including
refractory anemia with excess blasts in transformation or chronic myelomonocytic leukemia
(CMML), or acute myeloid leukemia (AML). This study will also assess the safety of ASTX727.
