The purpose of this study is to describe the dose limiting toxicities (DLT) and define the maximum tolerated dose (MTD) of ASP2215 when combined with cytarabine/idarubicin remission induction in a 7+3 schedule. Safety and tolerability of ASP2215 will also be evaluated. This study will also characterize the pharmacokinetics (PK) of ASP2215 when given in combination with cytarabine/idarubicin remission induction and high-dose cytarabine (HiDAC) consolidation therapy in newly diagnosed acute myeloid leukemia as well as evaluate the effect of ASP2215 on the PK of cytarabine.
