Kaplan Meier Estimates for Overall Survival (OS)Secondary· Until the end of the survival follow-up period; Up to data cut-off of 29 January 2015; 894 days
Overall survival is defined as time to death from any cause, is calculated using date of first dose and date of death, or date of last follow-up for censored participants. Those, who die regardless of the cause of death, will be considered to have an event.

Number of Participants With Treatment Emergent Adverse Events (TEAE) During the Parent PhaseSecondary· Up to 29 January 2015; from the first dose of study drug to 28 days after the date of the last dose of study drug (maximum time on study was 244 days)
A treatment-emergent adverse events (TEAE) was defined as AEs with an onset date on or after the date of first dose and within 28 days after the date of the last dose. Any AE that occurred beyond this timeframe and was assessed by the investigator as possibly related to study drug was considered treatment-emergent. The intensity and severity of AEs was assessed by the investigator according to the Common Terminology Criteria for Adverse Event (CTCAE) Version 4.0. For any AEs not listed in the CTCAE grading system, the intensities of these events was assessed by the Investigator using the 5-poi

Area under the plasma concentration-time curve from time zero to infinity (AUC∞) following multiple doses of Azacitidine on Day 7; if possible, the area under the concentration-time curve from time zero to infinity, calculated by the linear trapezoidal rule and extrapolated to infinity was calculated according to the following equation: AUC∞ = AUCt + (Ct/ λz ), where Ct is the last quantifiable concentration. No AUC extrapolation will be performed with unreliable λz. If % AUC extrapolated is ≥ 25%, AUC∞ will not be reported

Adverse events — posted to ClinicalTrials.gov
Time frame: Azacitidine Exposure across all cycles: median duration of azacitidine treatment was 786 days (range 428 to 1507)..
Reporting threshold: 5%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
The purpose of the study is to determine whether azacitidine is safe and effective in the treatment of Chinese patients with higher risk Myelodysplastic Syndromes (MDS).
