Primary Outcome Measures
NameTimeMethod
Number of Participants With AmenorrheaThe last 28 days of treatment period 1

Amenorrhea was defined as menstrual blood loss (MBL) \< 2 mL during the last 28 days of treatment. The evaluation of MBL was based on the Alkaline hematin (AH) method.

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Heavy Menstrual Bleeding (HMB) ResponseThe last 28 days of treatment period 1 and treatment period 2

HMB was defined as MBL \<80.00 mL during the last 28 days of treatment and \>50% reduction compared to baseline (assessed by the AH method).

Number of Participants by Endometrial Biopsy Main Results (Majority Read, Main Diagnosis)Up to 36 weeks

Number of participants with endometrial histology findings, e.g. benign endometrium, malignant neoplasm, hyperplasia without atypia, hyperplasia with atypia and endometrial polyps.

Change From Baseline of Endometrial ThicknessIn treatment period 1 (12 weeks) and in treatment period 2 (12 weeks)

Ultrasound examinations were performed. Endometrial thickness was measured in the medio-sagittal section as double-layer in millimeters. Summary statistics for change from baseline in endometrial thickness was provided in below table.

Time to Onset of AmenorrheaIn treatment period 1 (12 weeks) and in treatment period 2 (12 weeks)

Onset of amenorrhea was defined by the first day for which the MBL for all subsequent 28-day periods up to the end of a treatment period was \<2 mL (amenorrhea defined similar to primary endpoint and assessed by the AH method).

Time to Onset of Controlled BleedingIn treatment period 1 (12 weeks) and in treatment period 2 (12 weeks)

Onset of controlled bleeding was defined by the first day for which the MBL for all subsequent 28-day periods up to the end of a treatment period was \<80.00 mL (assessed by the AH method).

Number of Participants With Absence of Bleeding (Spotting Allowed)The last 28 days of treatment period 1 and treatment period 2

Absence of bleeding was defined as no scheduled or unscheduled bleeding (spotting allowed) during the last 28 days of a treatment period based on subjects' daily responses to the UF-DBD (Uterine Fibroid Daily Bleeding Diary).
