Trial Design
A multicenter, open-label, three-arm, active-controlled study to assess the efficacy and safety of the oral contraceptive SH T00186D (0.02 mg ethinyl estradiol as betadex clathrate and 3 mg drospirenone) in two flexible extended regimens and a conventional regimen of YAZ in 1756 healthy females for 1 year

Trial Arms:

Primary Outcome
- Pearl IndexThe Pearl Index (PI) is the number of pregnancies per 100 woman years. The PI is obtained by dividing the number of pregnancies during treatment (conception date on/after the 1st day of treatment and not later than last day of treatment +14 days) by the treatment exposure time (in 100 women years) that the women were under risk of getting pregnant. The Pearl Index was not calculated individually for either the Flexible (Extended) Regimen no. 2 of EE20/DRSP (BAY86-5300) treatment arm, nor for the Conventional Regimen of EE20/DRSP (YAZ, BAY86-5300) treatment arm, because the low sample size in these treatment arms (approximately. 200 subjects per group) did not allow a reliable PI calculation of these groups alone.Timeframe: Up to 1 year
Secondary Outcome
- Number of bleeding days (including spotting days)Number of days per participant with bleeding or spottingTimeframe: Up to 1 year
- Number of bleeding days (excluding spotting days)Number of days per participant with bleeding (excluding spotting days)Timeframe: Up to 1 year
- Number of days with bleeding (including and excluding spotting) within 90-day reference period 1.Number of days per participant with bleeding (including and excluding spotting) within 90-day reference period 1. Reference period 1 (Day 1 to Day 90) was a 90 day period starting with the initial intake of study medication (protocol-specified to occur on first day of menstrual or withdrawal bleeding after screening). Therefore, the first 90-day reference period contains additional bleeding days (associated with the menstrual cycle prior to the start of study medication) when compared to any other reference period.Timeframe: Day 1 to Day 90
- Number of days with bleeding (including and excluding spotting) within 90-day reference period 2.Number of days per participant with bleeding (including and excluding spotting) within 90-day reference period 2. Reference period 2 (Day 91 to Day 180) was a 90-day period that started with the intake of study medication at the beginning of Cycle 4.Timeframe: Day 91 to Day 180
- Number of days with bleeding (including and excluding spotting) within 90-day reference period 3Number of days per participant with bleeding (including and excluding spotting) within 90-day reference period 3. Reference period 3 (Day 181 to Day 270) was a 90-day period that started with the intake of study medication at the beginning of Cycle 7.Timeframe: Day 181 to Day 270
- Number of days with bleeding/ (including and excluding spotting) within 90-day reference period 4Number of days per participant with bleeding (including and excluding spotting) within 90-day reference period 4. Reference period 4 (Day 271 to Day 360) was a 90-day period that started with the intake of study medication at the beginning of Cycle 10.Timeframe: Day 271 to Day 360
