Study Details

Study Description

Brief Summary

This is a multi-center, randomized, double-blinded, placebo-controlled, parallel-group study (24-week treatment-comparison phase) with an open-label reference arm of active comparator (dienogest) followed by 28-week long-term treatment phase.

The primary objective of this study is to confirm the superiority of BAY86-5300 when administered with an extended flexible regimen for the treatment of endometriosis-associated pelvic pain in comparison to placebo in Japanese endometriosis patients within 24 weeks.

The secondary objective is to investigate the long-term safety of BAY86-5300 in patients treated with an extended flexible regimen for one year, and the bleeding pattern of BAY86-5300 when administered with an extended flexible regimen compared to dienogest.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Arm 1

Drug: EE20/DRSP(BAY86-5300)
One tablet [0.02 mg of ethinylestradiol (β-CDC) and 3 mg of drospirenone] / day

Experimental: Arm 2

Drug: Placebo
One tablet (no active ingredient) / day and one tablet [0.02 mg of ethinylestradiol (β-CDC) and 3 mg of drospirenone] / day, for the first 24 weeks and the later 28 weeks, respectively

Active Comparator: Arm 3

Drug: Dienogest
Dienogest 1mg twice a day (bid)

Outcome Measures

Primary Outcome Measures

  1. Change of pelvic pain from baseline period (8 weeks before start of treatment) to period of treatment (weeks 17-24) [Baseline period (8 weeks before start of treatment) and period of treatment (weeks 17-24)]

    The pelvic pain is measured as the severest pain marked by the participant on a Visual Analogue Scale (VAS)

Secondary Outcome Measures

  1. Pelvic pain during menstrual or withdrawal bleeding period (except for dyspareunia and defecation pain) [Weeks 17-24 of treatment period]

    Pelvic pain is the worst pain on a 0-10 scale rated by the participant.

  2. Pelvic pain during non-menstrual period and non-withdrawal bleeding period (except for dyspareunia and defecation pain) [Weeks 17-24 of treatment period]

    Pelvic pain is the worst pain on a 0-10 scale rated by the participant.

  3. Dyspareunia [Weeks 17-24 of treatment period]

    In case having sexual intercourse, dyspareunia pain is the worst pain on a 0-10 scale rated by the participant in the last 24 hours.

  4. Average of pain [Weeks 17-24 of treatment period]

    The average of pain is the mean value of the Visual Analogue Scale (VAS) value during the time frame calculated for each patient based on daily record of Patient Diary.

  5. Size of chocolate cyst [24 weeks after taking the initial study medication]

    In case chocolate cyst is detected, size of chocolate cyst is a mean length (mm) of the longest axis and the short axis (crossing) of the largest chocolate cyst determined by transvaginal ultrasonography.

  6. Endometrial thickness [24 weeks after taking the initial study medication]

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

  7. Number of days with spotting/bleeding [Up to 52 weeks]

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