What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Tolerated Dose (MTD) of BAY1143572 in Advanced Acute Leukemia Subjects | The MTD was defined as the highest dose that could be given such that not more than 20% of subjects experience a dose limiting toxicity (DLT) during Cycle 1. The study was terminated prior to the determination of MTD and hence no data was presented. | After the first 28 days of treatment (cycle 1) | 
| Maximum Total Observed Drug Concentration (Cmax) of BAY1143572 after Single Dose Administration in Plasma | Maximum total observed drug concentration of BAY1143572 after single dose administration in plasma was measured. | Pre-dose up to 24 hours post-dose on Cycle1 Day 1 | 
| Maximum Total Observed Drug Concentration of BAY1143572 after Multiple Dose Administration in Plasma (Cmax,md) | Maximum total observed drug concentration of BAY1143572 after multiple dose administration in plasma was measured. | Pre-dose up to 24 hours post-dose on Cycle 1 Day 15 | 
| Area Under the Concentration Versus Time Curve from Zero to 24 hours (AUC[0-24h]) of BAY1143572 in Plasma After Single Dose Administration | Area under the concentration versus time curve from zero to 24 hours of BAY1143572 in plasma after single dose administration was measured. | Pre-dose up to 24 hours post-dose on Cycle1 Day 1 | 
| Area Under the Concentration Versus Time Curve from Zero to 24 hours of BAY1143572 in Plasma after Multiple Dose Administration (AUC[O-24h]md) | Area under the concentration versus time curve from zero to 24 hours of BAY1143572 in plasma after multiple dose administration was measured. | Pre-dose up to 24 hours post-dose on Cycle 1 Day 15 | 
| Area Under the Concentration Versus Time Curve from Zero to Last Data Point Greater than Lower Limit of Quantitation (LLOQ) of BAY1143572 in Plasma (AUC[0-tlast]) after Single Dose Administration | Area under the concentration versus time curve from zero to last data point greater than lower limit of quantitation of BAY1143572 in plasma after single dose administration was measured. | Pre-dose up to 24 hours post-dose on Cycle 1 Day 1 | 
| Time to Reach Maximum Drug Concentration (tmax) of BAY1143572 in Plasma after Single Dose Administration | Time to reach maximum drug concentration of BAY1143572 in plasma after single dose administration was measured. | pre-dose up to 24 hours post-dose on Cycle 1 Day 1 | 
| Time to Reach Maximum Drug Concentration of BAY1143572 in Plasma after Multiple Dose Administration (tmax,md) | Time to reach maximum drug concentration of BAY1143572 in plasma after multiple dose administration was measured. | Pre-dose up to 24 hours post-dose on Cycle 1 Day 15 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Subjects With Leukemia Response | Bone marrow aspirates / biopsies / peripheral whole blood were taken and assessed for leukemia response evaluation. Assessment of response was made based on the revised recommendations of the International Working Group (Cheson 2003 criteria). Criteria proposed by Cheson 2003 for leukemia: complete remission (CR), morphological CR with incomplete blood count recovery (CRi), partial remission (PR), no response / treatment failure, relapse from CR, CRi, or PR. | From start of treatment of the first subject until 28 days | 
| Number of Subjects with Treatment Emergent Adverse Events (TEAEs) and Treatment Emergent Serious Adverse Events (TESAEs) | An adverse event (AE) was any untoward medical occurrence in subject who received study drug without regard to possibility of causal relationship. AEs that started or worsened after first administration of study medication up to 30 days after end of treatment with study medication were considered to be treatment emergent (TE). A serious adverse event (SAE) was an AE resulting in any of following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly and another medical important serious event as judged by investigator. SAEs that started or worsened after study drug treatment were recorded as TESAEs. | From start of study drug administration up to 30 days after the last dose of study drug administration (approximately 2.5 years) | 
| Area Under the Concentration Versus Time Curve from Zero to Infinity (AUC) of BAY1143572 after Single Dose Administration in Plasma | Area under the concentration versus time curve from zero to infinity of BAY1143572 after single dose administration in plasma was measured. | Pre-dose up to 24 hours post-dose on C1D1 |
