Up to 8 criteria had to be met for complete response during 90-day period. No bleeding episodes (BE) >7 days, no >4 BE, no BE with MBL >=80 mL, no >1 BE increase from baseline, no increase from baseline in an individual participant's total number of bleeding days and total number of bleeding days not >24 days. Additionally, for participants included with prolonged bleeding: decrease between maximum duration during run-in and efficacy >=2 days excessive bleeding: MBL associated with each episode decreased by >=50% from average of qualifying episodes during run-in.

The intent-to-treat (ITT) group consisted of all randomized participants.

Prolonged bleeding was defined as 2 or more bleeding episodes, each lasting 8 or more days in a 90-day period. Participants were considered cured if they had no bleeding episodes lasting more than 7 days and the decrease between the maximum duration during the run-in phase and the maximum duration during the efficacy phase was at least 2 days.

The ITT population consisted of all randomized participants who enrolled with prolonged bleeding.

Frequent bleeding was defined as greater than 5 bleeding episodes, with a minimum of 20 bleeding days overall in a 90-day period. Participants were considered cured if they had no more than 4 bleeding episodes and the total number of bleeding days did not exceed 24 days and there was no increase in the total number of bleeding days in the efficacy phase as compared to the run-in phase.

The ITT population consisted of all randomized participants who enrolled with frequent bleeding.

Excessive bleeding was defined as 2 or more bleeding episodes each with blood loss volume of 80 mL or more in a 90-day period. Participants were considered cured if (1) the blood loss volume associated with each episode was less than 80 mL and (2) the blood loss volume associated with each bleeding episode represented a decrease of at least 50% from the average of the qualifying bleeding episodes, where the qualifying bleeding episodes were those with a blood loss volume ≥ 80 mL (per episode) that occurred during the run-in phase.

The ITT population consisted of all randomized participants who enrolled with excessive bleeding.

The investigators assessed the participants' change in DUB symptoms at day 84 (visit 7) compared with admission to the study according to a scale of 1 (very much improved) to 7 (very much worse), using the following information: central laboratory data, physical examination, e-diary data, and participant interview. Improvement was defined as being classified as a score of 3 or less.

The Health State Classification of the EQ-5D comprised 5 questions addressing mobility, self-care, usual activity, pain/discomfort, and anxiety/depression. Participants were asked to indicate their current health state by ticking the most appropriate of 3 statements about each of the questions (ie, no problems, some problems, extreme problems). The best possible answers were (1,1,1,1,1), which equals a valuation score of 1.0. The worst possible answers were (3,3,3,3,3), which equals a valuation score of .594. The change from the baseline score at day 84 is presented.

End of Study menstrual blood loss (MBL) ≤ 80 mL and a decrease to a value of ≤ 50% of the Baseline MBL was considered as treatment success.

Only participants with heavy menstrual bleeding were included in the analysis.

The MBL for each cycle includes intermenstrual bleeding in addition to withdrawal bleeding. Baseline MBL was the mean MBL of measured MBL during three cycles in the run-in Phase. One cycle was defined as 28 days. For this analysis, the run-in Phase was defined by the days 1 to 84 (= 3 cycles each of 28 days). End of Study MBL was measured during Cycle 7 of the Treatment Phase (data imputation and Last Observation Carried Forward was applied).

Only participants with heavy menstrual bleeding were included in the analysis.
