Arms and Interventions

Arm Intervention/Treatment
Experimental: Flexible (extended) regimen no. 1 of EE20/DRSP (BAY86-5300)

Minimum of 3 cycles of treatment, each cycle comprising 120 days (maximum) intended treatment with one tablet daily of BAY86-5300 (SH T00186D) followed by a 4-day tablet-free interval. If 3 consecutive days of bleeding and/or spotting occurred between days 25 to 120 of the treatment cycle, a 4-day tablet-free interval was advised. The minimum period between 2 tablet-free intervals was 24 days. After each 4-day tablet-free interval, a new 124-day intended treatment cycle was to be restarted, resulting in a minimum of 3 and maximum of 13 withdrawal bleeding episodes during one year of treatment

Drug: EE20/DRSP (BAY86-5300)
Combination tablet containing 0.02 mg ethinyl estradiol as betadex clathrate and 3.0 mg drospirenone
Other Names:
  • SH T00186D
  • Experimental: Flexible (extended) regimen no. 2 of EE20/DRSP (BAY86-5300)

    Minimum of 3 cycles of treatment, each cycle comprising 120 days (maximum) uninterrupted treatment with one tablet daily of BAY86-5300 (SH T00186D) and a 4-day tablet-free interval. Subjects were permitted to schedule their withdrawal bleeding (ie, 4-day tablet-free interval) at any time between days 25 to 120 of the cycle. Subjects had the option to follow the bleeding rules of the flexible (extended) regimen no. 1 of BAY86-5300. The minimum period between 2 tablet-free intervals was 24 days. After each 4-day tablet-free interval, a new 124-day intended treatment cycle was to be restarted, resulting in a minimum of 3 and maximum of 13 withdrawal bleeding episodes during one year of treatment.

    Drug: EE20/DRSP (BAY86-5300)
    Combination tablet containing 0.02 mg ethinyl estradiol as betadex clathrate and 3.0 mg drospirenone
    Other Names:
  • SH T00186D
  • Active Comparator: Conventional regimen of EE20/DRSP (YAZ, BAY86-5300)

    13 cycles of treatment, each cycle comprising an intake of one tablet daily with 24 days of active tablets of BAY86-5300 (YAZ, SH T00186D) followed by 4 days of tablets without active substance (together resulting in one cycle of 24+4 standard treatment). 13 withdrawal bleeding episodes during one year of treatment were expected.

    Drug: EE20/DRSP (YAZ, BAY86-5300)
    Fixed package per cycle containing combination tablets containing 0.02 mg ethinyl estradiol as betadex clathrate and 3.0 mg drospirenone (24 per cycle) + tablets without active substance (4 per cycle)
    Other Names:
  • SH T00186D
  • Outcome Measures

    Primary Outcome Measures

    1. Pearl Index [Up to 1 year]

      The 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.

    Secondary Outcome Measures

    1. Number of Bleeding Days (Including Spotting Days) [Up to 1 year]

      Number of days per participant with bleeding or spotting

    2. Number of Bleeding Days (Excluding Spotting Days) [Up to 1 year]

      Number of days per participant with bleeding (excluding spotting days)

    3. Number of Days With Bleeding (Including and Excluding Spotting) Within 90-day Reference Period 1. [Day 1 to Day 90]

      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.

    4. Number of Days With Bleeding (Including and Excluding Spotting) Within 90-day Reference Period 2. [Day 91 to Day 180]

      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.

    5. Number of Days With Bleeding (Including and Excluding Spotting) Within 90-day Reference Period 3 [Day 181 to Day 270]

      Number 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.

    6. Number of Days With Bleeding/ (Including and Excluding Spotting) Within 90-day Reference Period 4 [Day 271 to Day 360]

      Number 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.

      Scheduled bleeding is any bleeding/spotting (bl/sp) that occurs during the tablet free interval through the next 4 days of the subsequent treatment cycle. Unscheduled bleeding is any bl/sp that occurs while taking active hormones, except for bl/sp that occurs during the tablet free interval through day 4 of the subsequent treatment cycle or bl/sp on days 1-7 of treatment cycle 1.

A tablet-free interval (treatment withdrawal) was defined as at least 3 consecutive days without tablet intake. For the standard 24+4 treatment arm, a new cycle started each time a new blister pack of medication was started.

The minimum period between 2 tablet-free intervals was 24 days. After each 4-day tablet-free interval, a new 124-day intended treatment cycle was to be restarted, resulting in a minimum of 3 and maximum of 13 withdrawal bleeding episodes during one year of treatment Minimum of 3 cycles of treatment, each cycle comprising 120 days (maximum) uninterrupted treatment with one tablet daily of BAY86-5300 (SH T00186D) and a 4-day tablet-free interval. Subjects were permitted to schedule their withdrawal bleeding (ie, 4-day tablet-free interval) at any time between days 25 to 120 of the cycle. Subjects had the option to follow the bleeding rules of the flexible (extended) regimen no. 1 of BAY86-5300. The minimum period between 2 tablet-free intervals was 24 days. After each 4-day tablet-free interval, a new 124-day intended treatment cycle was to be restarted, resulting in a minimum of 3 and maximum of 13 withdrawal bleeding episodes during one year of treatment. 13 cycles of treatment, each cycle comprising an intake of one tablet daily with 24 days of active tablets of BAY86-5300 (YAZ, SH T00186D) followed by 4 days of placebo tablets (SH T470PD). 13 withdrawal bleeding episodes during one year of treatment were expected.

    Outcome Measures

    1. Primary Outcome
    Title Pearl Index
    Description The 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.
