Primary Outcome Measures
NameTimeMethod
Percentage of Participants Meeting the Criteria for ResponderFrom Month 0 (Baseline in Pivotal Study) to Final Month of Treatment Period (up through Month 6 in Extension Study)

Percentage of responders, defined as participants who met the following conditions:

* Menstrual blood loss (MBL) volume \< 80 mL during the Final Month (the last 28 days prior to and including the last dose date), and

* ≥ 50% reduction in MBL volume from Baseline to the Final Month.

Participants who prematurely discontinued study drug due to "lack of efficacy," "requires surgery or invasive intervention for treatment of uterine fibroids," or "adverse events" were considered non-responders regardless of whether she meets the two aforementioned responder criteria or not.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Suppression of Bleeding at the Final MonthFinal Month of Treatment Period (up through Month 6)

Suppression of bleeding is defined as having 0 days of bleeding (spotting is allowed) during the Final Month with the interval starting from Study Day 11.

Change From Baseline in MBL Volume For Each 28-Day Interval and Final Month of the Treatment PeriodMonth 0 (Baseline in Pivotal Study), Extension Study: Day 1 to 28, Day 29 to 56, Day 57 to 84, Day 85 to 112, Day 113 to 140, Day 141 to 168, Final Month of Treatment Period (up through Month 6)

Baseline MBL volume was defined as the mean of total MBL volume from all the qualified menstrual cycles during the Screening Period of the pivotal study, in which the total MBL volume is from all validated and non-validated sanitary products and the MBL volume of validated sanitary products only (excluding non-validated sanitary products) was greater than 80 mL.

Percentage of Participants With Baseline Hemoglobin Concentration ≤ 10.5 g/dL and an Increase From Baseline > 2 g/dL at Month 6 During the Treatment PeriodMonth 6
