Outcome Measures

1. Primary: | Number of In-treatment Pregnancies (With +2 Day Window) Per 100 Woman Years of Exposure (Pearl Index) [ Time Frame: 1 year (13 cycles) ] |

Measure Type | Primary |
---|---|

Measure Title | Number of In-treatment Pregnancies (With +2 Day Window) Per 100 Woman Years of Exposure (Pearl Index) |

Measure Description | In-treatment pregnancies were pregnancies with an estimated date of conception from the day of first intake of trial medication up to and including the day of last (active or placebo) intake of trial medication extended with a maximum of two days. Each 13 cycles (28 days per cycle) of exposure constitutes a woman year. The Pearl Index was obtained by dividing the number of in-treatment pregnancies that occurred by the time (in 100 women years) that the women were under risk of becoming pregnant. |

Time Frame | 1 year (13 cycles) |

Population Description

Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate. |
---|

The "restricted ITT" set included all participants treated except for 27 nonpregnant participants whose exposure was excluded due to limited credibility of diary data, & also excluded nonpregnant participants without >= 1 cycle expected to be at risk for pregnancy (with recorded use of condoms or w/o sexual intercourse, based on e-diary data). |

Measure Type | Secondary |
---|---|

Measure Title | Number of Participants With an Occurrence of Breakthrough Bleeding/Spotting |

Measure Description | Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using e-diaries. Participants documented whether vaginal bleeding was present, and if present, indicated whether it was considered to be spotting or bleeding. Breakthrough bleeding/spotting was defined as any episode that occurred during the "expected non-bleeding period" that was neither an early nor a continued withdrawal bleeding. Expected non-bleeding period: DRSP-EE group: 21-day period starting on Day 1 of the cycle; NOMAC-E2: 21-day period starting on Day 4 of the cycle. |

Time Frame | Every 28-day cycle for 13 cycles (one year total) |

Population Description

The ITT group consisted of all participants who were treated; ITT analyses of vaginal bleeding patterns were based on all participants in the ITT group who had at least one evaluable cycle. Cycles were considered to be non-evaluable in case of insufficient bleeding data or improper cycle length. n= number of participants with evaluable cycles. |

Measure Title | Number of Participants With an Occurrence of Absence of Withdrawal Bleeding |

Measure Description | Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using e-diaries. Participants documented whether vaginal bleeding was present, and if present, indicated whether it was considered to be spotting or bleeding. Absence of withdrawal bleeding was defined as no bleeding/spotting episode that began during or continued into the "expected bleeding period". Expected bleeding period: DRSP-EE group: 7-day period starting on Day 22 of the cycle; NOMAC-E2: 7-day period starting on Day 25 of the cycle and ending on Day 3 of the next cycle. |

Time Frame | Every 28-day cycle for 13 cycles (one year total) |

Measure Title | Number of Participants With an Occurrence of Continued Withdrawal Bleeding |

Measure Description |
Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using e-diaries. Participants documented whether vaginal bleeding was present, and if present, indicated whether it was considered to be spotting or bleeding. Continued withdrawal bleeding was defined as any withdrawal bleeding that continued into the "expected non-bleeding period" of the next cycle. Expected non-bleeding period: DRSP-EE group: 21-day period starting on Day 1 of the cycle; NOMAC-E2: 21-day period starting on Day 4 of the cycle. |

Time Frame | Every 28-day cycle for 12 cycles |

Measure Title | Average Number of Breakthrough Bleeding/Spotting Days |

Measure Description | Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using e-diaries. Participants documented whether vaginal bleeding was present, and if present, indicated whether it was considered to be spotting or bleeding. Breakthrough bleeding/spotting was defined as any episode that occurred during the "expected non-bleeding period" that was neither an early nor a continued withdrawal bleeding. Expected non-bleeding period: DRSP-EE group: 21-day period starting on Day 1 of the cycle; NOMAC-E2: 21-day period starting on Day 4 of the cycle. |

Time Frame | Every 28-day cycle for 13 cycles (one year total) |

Population Description

ITT analyses of vaginal bleeding patterns were based on all participants in the ITT group who had at least one evaluable cycle. Cycles were considered to be non-evaluable in case of insufficient bleeding data or improper cycle length. n= number of participants who had breakthrough bleeding/spotting for the respective cycle. |
