| Number of Participants With Dose Limiting Toxicities (DLT) in Cycle 1 for the Determination of the Maximum Tolerated Dose (MTD) of Volasertib | From first administration of trial drug up to 28 days | Primary objective for this trial was to identify the MTD of volasertib. The MTD was defined as the highest dose level at which DLTs were reported in at most 2 in 6 evaluable patients during cycle 1. In this outcome measure the number of participants with DLTs in cycle 1 is presented. |

In this outcome measure the CRi will be presented. The criteria for the CRi are: All CR criteria are met except for residual neutropenia (\<1.0 × 10\^9/L \[1000/μL\]) or thrombocytopenia (\<100 × 10\^9/L \[100 000/μL\]). |
| Best Response by PR | From first administration of trial drug up to 486 days | The secondary outcome best response will be presented by the CR, CRi and PR. In this outcome measure the PR is presented. The criteria for the PR are: All haematologic criteria of CR; decrease of bone marrow blast percentage to 5% to 25%; and decrease of pretreatment bone marrow blast percentage by at least 50%. |
| Remission Duration | From first administration of trial drug up to 486 days | The remission duration is the time from the date of achieving CR or CRi until relapse for patients with documented CR or CRi. |
