- Primary Outcome Measures
Name Time Method Percentage of Responders based on menstrual blood loss (MBL) volume reduction at Week 24. The last 28 days before the Week 24. MBL will be determined using the Alkaline Hematin method (AHM). Responder means whose MBL less than 80mL during the last 28 days before the Week 24 and more than 50% reduction in MBL compared to the baseline.
- Secondary Outcome Measures
Name Time Method Time to reduced MBL before the Week 24. From baseline to Week 24. Reduced MBL means MBL less than 80ml and more than 50% reduction in MBL compared to the baseline.
Percentage of amenorrhea at the Week 24. From baseline to Week 24. Amenorrhea is defined as having 0 data (or volume below the lower limit of quantification) from the AHM of MBL from the central laboratory or missing of AHM data with reported of "spotting" or "no bleeding" in the eDiary for 35 days before Week 24.
Time to amenorrhea before the Week 24. From baseline to Week 24. The number of days from Study Day 1 to the first day having amenorrhea.
Days of menstrual bleeding in the last 28 days before the Week 24. The last 28 days before the Week 24. Record the number of days.
Hemoglobin levels at the Week 24 in the subgroup of subjects with anemia. The Week 24. Anemia is defined as hemoglobin below 12g/dL at baseline.
