Primary Outcome Measures
NameTimeMethod
Number of days with dysmenorrheic pain over 140 days of evaluation periodEvaluation period which starts on 25th day after start of treatment and lasts for 140 days

Number of days with dysmenorrheic pain is determined based on daily record of Patient Diary.

Secondary Outcome Measures
NameTimeMethod
Change in Dysmenorrhea score from baseline to period of withdrawal bleedingBaseline period (8 weeks before start of treatment) and evaluation period which starts on 25th day after start of treatment and lasts for 140 days

Dysmenorrhea score is a sum of the two sub-scores, severity of dysmenorrhea and use of analgesics, recorded by the participant at every visit

Number of days with at least moderate dysmenorrheic pain over 140 days of evaluation periodEvaluation period which starts on 25th day after start of treatment and lasts for 140 days

Number of days with at least moderate dysmenorrheic pain is determined based on daily record of Patient Diary.

Number of days with rescue medicine used for relief of dysmenorrhea or pelvic pain over 140 days of evaluation periodEvaluation period which starts on 25th day after start of treatment and lasts for 140 days

Number of days with rescue medicine is determined based on daily record of Patient Diary.

Endometrial thickness24 weeks after taking the initial study medication

Endometrial thickness is the thickest value (mm) of endometrium determined by transvaginal ultrasonography.

Number of days with bleeding and spotting over treatment phaseUp to 24 weeks

Number of days with spotting/bleeding is determined based on daily record of Patient Diary.

Change of severity of pain DescriptionBaseline period (8 weeks before start of treatment) and evaluation period which starts on 25th day after start of treatment and lasts for 140 days

The severity of pain is measured by the Visual Analogue Scale (VAS), recorded by the participant at any visit.

Number of days with interference of dysmenorrheic pain with daily activity over 140 days of evaluation periodEvaluation period which starts on 25th day after start of treatment and lasts for 140 days

Number of days with interference of dysmenorrheic pain with daily activity is determined based on daily record of Patient Diary
