简要总结
The objectives of this trial are to evaluate the safety, tolerability, maximum tolerated dose (MTD), pharmacokinetics and preliminary efficacy of volasertib in two dosing schedules of intravenous volasertib as monotherapy or in combination with azacitidine in patients with myelodysplastic syndrome (MDS) after hypomethylating agents (HMA) treatment failure.

结局指标
主要结局
Number of Patients With Dose Limiting Toxicities (DLT) in the First Cycle
时间窗: First treatment cycle, up to 28 days
DLT was defined as any of the following adverse events (AEs) considered to be related to study drug: 1. Common terminology criteria for adverse events (CTCAE) v4.03 ≥Grade 3 drug related non- haematological toxicity, excluding; ≥Grade 3 untreated nausea, vomiting or diarrhea. Any laboratory abnormality - not considered clinically significant by investigator or resolved spontaneously or could have been recovered with appropriate treatment within 7 days. Grade 3 infection which could be recovered with appropriate treatment within 7 days. Azacitidine injection site reaction or complications related to azacitidine injection. 2. Febrile neutropenia as defined by CTCAE which could not recovered with appropriate treatment within 7 days. 3. Inability to deliver full dose of volasertib according to the assigned dose level within Cycle 1 due to drug-related AEs. 4. Haematological DLTs. 5. Any other drug-related AEs that resulted in the delay of starting new treatment cycle for ≥4 weeks.
Maximum Tolerated Dose (MTD) of Volasertib
时间窗: First treatment cycle, up to 28 days
The MTD was defined as the highest dose with less than 35% risk of the true dose limiting toxicities (DLT) rate being above 0.33 for schedule A, and the highest dose with less than 40% risk of the true DLT rate being above 0.33 for schedule B. The phase I dose-finding was to be guided by a Bayesian 2-parameter logistic regression model (BLRM) with overdose control in each schedule separately.

- Area Under the Plasma Concentration-time Curve Over the Time Interval From Zero Extrapolated to Infinity of Volasertib (AUC0-∞) (for Combination)(PK samples were to be taken at 5 minutes before drug administration (167:55) and 168:30, 169:00, 169:30, 170:00, 171:00, 172:00, 192:00, 336:00, 504:00, 672:00 hours after first drug administration of Azacitidine)
- Maximum Measured Plasma Concentration of Volasertib (Cmax) (for Combination)(PK samples were to be taken at 5 minutes before drug administration (167:55) and 168:30, 169:00, 169:30, 170:00, 171:00, 172:00, 192:00, 336:00, 504:00, 672:00 hours after first drug administration of Azacitidine)
