Efficacy and Safety Study for the Treatment of Dysfunctional Uterine Bleeding

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.

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.

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.

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 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 investigators assessed the participants' change in DUB symptoms at day 196 (visit 11) 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.

Menstrual blood loss was determined using the alkaline hematin method for the 90 days before treatment (baseline) and for 90 days under treatment. A negative value indicates a reduction in blood loss after treatment.

The blood loss volume for participants with excessive bleeding (2 or more bleeding episodes each with blood loss volume of 80 mL or more during the run-in phase) was determined for the 90 days before treatment (ie, run-in phase) and for the 90 days under treatment. A negative value indicates a reduction in blood loss while under treatment compared to before treatment.

The blood loss volume for participants with excessive bleeding (2 or more bleeding episodes each with blood loss volume of 80 mL or more during the run-in phase) was determined using the alkaline hematin method after participants were on treatment for 7 cycles.

The number of bleeding days was determine for the 90 days before treatment (baseline) and for 90 days while under treatment. A negative value indicates a reduction in the number of bleeding days while under treatment compared to baseline.

A bleeding episode was one that lasted for at least 2 days, and where the bleeding days were separated by no more than 1 bleeding-free day. An episode stopped with 2 consecutive bleeding-free days. The number of episodes was determined for the 90 days before treatment and for the 90 days under treatment. A negative values indicates a reduction from baseline in the number of episodes while under treatment.

The number of total sanitary protection items used during the 90-day run-in phase before treatment (baseline) and the number of total sanitary protection items used during the 90 days while under treatment was determined. A negative value indicates a reduction in the number of sanitary protection items used while under treatment compared to the number used before treatment.

The PGWBI questionnaire consisted of 22 questions that were answered using a 6-grade Likert scale. The minimum overall score was 22 and the maximum was 132. The higher the score, the better the well being of the participant. The observation phase was the last 4 weeks. The following 6 dimensions were derived from the questionnaire: anxiety, depressed mood, positive well-being, self-control, health, and vitality and the highest possible scores were 30, 18, 24, 18, 18, and 24, respectively.

The MFSQ was designed to measure aspects of female sexuality and asked about the participants' sexual experience during the last 4 weeks. Higher scores represent higher, more complete, or better integrated levels of female sexual function. Minimum and maximum possible values are 19 and 133.

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.

The visual analogue scale (ie, "thermometer") had endpoints of 100 (best imaginable health state) at the top, and 0 (worst imaginable health state) at the bottom. Participants rated their current health state by drawing a line from the box marked 'your own health state today' to the appropriate point on the thermometer scale. The change from baseline at day 84 is presented.
