About

The purpose of this study is to describe the dose limiting toxicities (DLT) of SKLB1028 when combined with cytarabine/ daunorubicin remission induction in a 7+3 schedule. Safety and tolerability of SKLB1028 will also be evaluated. This study will also characterize the pharmacokinetics (PK) of SKLB1028 when given in combination with cytarabine/daunorubicin remission induction and high-dose cytarabine (HiDAC) consolidation therapy in newly diagnosed acute myeloid leukemia .
