Eligibility
Inclusion criteria
* Adult patients with previously untreated, intermediate-2 or high- risk MDS or CMML not eligible for hematopoietic stem cell transplantation (HSCT) based on documented patients characteristics like age, performance status, concomitant diagnoses, and organ dysfunctions * Further inclusion criteria apply
Exclusion criteria
* Prior or concomitant therapy for higher risk MDS (for example, but not limited to, hypomethylating agents like azacitidine). Note: Prior treatment with erythropoetin (EPO) is allowed up to \> 1 week before treatment with study medication. Patients must have not received MDS therapy since diagnosis of higher-risk MDS. However, previous lenalidomide treatment could have been administered for lower-risk MDS treatment as long as this therapy was discontinued at least \> 4 weeks before initiation of the current study treatment. * Treatment with any investigational drug within 2 weeks before first administration of present trial drug or within less than 5 half lives of the investigational drug before treatment with the present trial drug, whichever is longer. * Second malignancy currently requiring active therapy (except for hormonal/anti-hormonal treatment, e.g. in prostate or breast cancer). * Corrected QT interval according to Fridericia (QTcF) prolongation \> 470 ms or QT prolongation deemed clinically relevant by the investigator (e.g., congenital long QT syndrome).The QTcF will be calculated as the mean of the 3 Electrocardiograms (ECGs) taken at screening. * Total bilirubin \> 1.5 x upper limit of normal not related to Gilberts disease, hemolysis, or secondary to MDS. * Aspartate amino transferase (AST) or alanine amino transferase (ALT) \> 2.5 x the upper limit of normal (ULN) Creatinine \> 1.5 x ULN * Active hepatitis B or hepatitis C, or laboratory evidence for a chronic infection (hepatitis test results done in routine diagnostics are acceptable if done within 14 days before first study treatment dose). * HIV infection (HIV test results in routine diagnostics are acceptable if done within 14 days before first study treatment dose). * Severe illness or organ dysfunction involving the kidney, liver or other organ system (e.g. active uncontrolled infection , unstable angina pectoris or history of severe congestive heart failure, clinically unstable cardiac disease or pulmonary disease), which in the opinion of the investigator would interfere with the evaluation of the safety of the study treatment * Further

The primary objective of the dose-escalation part of this study was to determine the MTD of volasertib in combination with azacitidine. The MTD was to be identified based on the DLT information collected during the first treatment cycle of each dosing schedule. DLT was defined as a non-haematological drug-related toxicity of Common Terminology Criteria for Adverse Events (CTCAE) grade ≥3.

Hence, a final conclusion of the MTD of volasertib in combination with azacitidine cannot be drawn in this trial. Number of patients with DLT in cycle 1 in escalation part is presented to determine MTD.
Time frame: 4 weeks
Population: MTD set: The MTD set was used for the first treatment cycle (Cycle 1) analysis and excluded any treated patients that missed any dose of trial medication in Cycle 1 for reasons other than DLT
