Brief Summary

This is a 4-arm study to evaluate and compare bleeding patterns between three different doses of DR-1031 oral contraceptive with Seasonale oral contraceptive. Study participants will receive physical and gynecological exams, including Pap smear. During the study, all participants will be required to complete a diary

Primary Outcome Measures
NameTimeMethod
Days With Bleeding and/or Spotting During Active Cycle 1 (Day 1-84)Day 1-84

Bleeding is defined as a flow heavy enough to require sanitary protection. Spotting does not require sanitary protection.

Days With Bleeding and/or Spotting During Active Cycle 2 (Day 92-176)Day 92-176

Bleeding is defined as a flow heavy enough to require sanitary protection. Spotting does not require sanitary protection.

Secondary Outcome Measures
NameTimeMethod
Days With Bleeding During Active Cycle 1 (Day 1-84)Day 1-84

Bleeding is defined as a flow heavy enough to require sanitary protection.

Days With Bleeding During Active Cycle 2 (Day 92-176)Day 92-176

Bleeding is defined as a flow heavy enough to require sanitary protection.

Time to First Bleeding DayDay 1-84

Time to first bleeding day was defined as the time between the start of intervention until the first day when bleeding was heavy enough to require the use of sanitary protection.

Data are not summarized due to limitations in the diary data and an inability to accurately determine a participant's first day of bleeding.

Maximum Bleeding Severity During Active Cycle 1 (Day 1-84)Day 1-84

Bleeding is defined as a flow heavy enough to require sanitary protection. Participants recorded in the diary days when they had bleeding, and whether they considered the bleeding to be light, moderate or heavy.

Data was not summarized due to limitations in the diary data, and an inability to accurately determine the maximum bleeding severity.

See pre-specified analyses for Number of Moderate to Heavy Bleeding Days.

Participants With Bleeding and/or Spotting Days During the 7-day Withdrawal During Cycle 1 (Day 85-91)Day 85-91

Participants are categorized by the duration of bleeding that occurred during the scheduled 7-day withdrawal period for Cycle 1.

Participants With Bleeding and/or Spotting Days During the 7-day Withdrawal During Cycle 2 (Day 177-183)Day 177-183

Participants are categorized by the duration of bleeding that occurred during the scheduled 7-day withdrawal period for Cycle 2.

Participants Reporting Hormone-Related Symptoms During Active Cycle 1 (Day 1-84)Day 1-84
