The purpose of this study is to determine the maximum tolerated dose (MTD) and/or recommended expansion dose (RED) of ASP2215 concomitant with cytarabine/idarubicin as induction chemotherapy based on the status of the onset of dose-limiting toxicity (DLT) in newly Diagnosed Acute Myeloid Leukemia (AML). Safety and tolerability of ASP2215 will also be evaluated. This study will also characterize the pharmacokinetic (PK) parameters of ASP2215 concomitant with induction and consolidation chemotherapy as well as evaluate the PK parameters of cytarabine concomitant with ASP2215.
