Outcome Measures

Primary Outcome Measures

  1. Effect on Ovarian Function as Determined by the Number of Participants With an Occurrence of Ovulation [Cycle 1, Cycle 2, and Cycle 6]

    During treatment, ovulation was assessed for each participant by the investigator on the basis of ultrasound scanning (USS). The final analysis was based on assessor-blind adjudication.

  2. Effect on Ovarian Function as Determined by the Maximum Follicle Diameter [Screening cycle, Cycle 1, Cycle 2, Cycle 3, and Cycle 6]

    The maximum follicular diameter was defined as the largest follicular diameter during a treatment cycle.

  3. Effect on Ovarian Function as Determined by the Maximum Progesterone Value [Screening cycle, Cycle 1, Cycle 2, Cycle 3, and Cycle 6]

    The maximum progesterone value was defined as the largest value during a cycle.

  4. Effect on Ovarian Function as Determined by 17 Beta-estradiol (E2) [Cycle 1, Cycle 2, Cycle 3, and Cycle 6]

    The parameter was measured at pre-defined study days.

  5. Effect on Ovarian Function as Determined by Follicle Stimulating Hormone (FSH) [Cycle 1, Cycle 2, Cycle 3, and Cycle 6]

    The parameter was measured at pre-defined study days.

  6. Effect on Ovarian Function as Determined by Luteinizing Hormone (LH) [Cycle 1, Cycle 2, Cycle 3, and Cycle 6]

    The parameter was measured at pre-defined study days.

Secondary Outcome Measures

  1. Effect on Cervical Mucus as Determined by Insler Score [Screening Cycle, Cycle 1, Cycle 2, and Cycle 7 (post-treatment cycle)]

    The Insler Score was assessed on Day 6 after ovulation during the Screening Cycle, on Day 21 of Cycle 1, and when the maximum follicle diameter was greater than or equal to 15 mm. The Insler Score consisted of four categories each scaled from 0 (none) to 3 (complete). The higher the score, the greater the cervical reaction.

  2. Effect on Maximum Endometrial Thickness [Screening Cycle, Cycle 1, Cycle 2, and Cycle 6]

    Maximum endometrial thickness was defined as the largest endometrial thickness during a cycle.

  3. Number of In-treatment Pregnancies (With +2 Day Window) Per 100 Woman Years of Exposure (Pearl Index) [6 cycles]

    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 woman years) that the women were under risk of becoming pregnant.

  4. Number of Participants With an Occurrence of Breakthrough Bleeding/Spotting [Every 28-day cycle for 6 cycles]

    Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary card booklets. 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.

  5. Number of Participants With an Occurrence of Absence of Withdrawal Bleeding [Every 28-day cycle for 6 cycles]

    Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary card booklets. 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.

  6. Number of Participants With an Occurrence of Breakthrough Bleeding [Every 28-day cycle for 6 cycles]

    Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary card booklets. Participants documented whether vaginal bleeding was present, and if present, indicated whether it was considered to be spotting or bleeding. Breakthrough bleeding was defined as any bleeding episode that occurred during the "expected non-bleeding period" that was neither part of an early nor 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.

  7. Number of Participants With an Occurrence of Breakthrough Spotting (Spotting Only) [Every 28-day cycle for 6 cycles]

    Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary card booklets. Participants documented whether vaginal bleeding was present, and if present, indicated whether it was considered to be spotting or bleeding. Breakthrough spotting was defined as any spotting episode that occurred during the "expected non-bleeding period" that was neither part of an early nor 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.

  8. Number of Participants With an Occurrence of Early Withdrawal Bleeding [Every 28-day cycle for 6 cycles]

    Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary card booklets. Participants documented whether vaginal bleeding was present, and if present, indicated whether it was considered to be spotting or bleeding. Early withdrawal bleeding was defined as any withdrawal bleeding that started before the current "expected bleeding period". Expected bleeding period: DRSP-EE: 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.

  9. Number of Participants With an Occurrence of Continued Withdrawal Bleeding [Every 28-day cycle for 5 cycles]

    Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary card booklets. 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.

  10. Average Number of Breakthrough Bleeding/Spotting Days [Every 28-day cycle for 6 cycles]

    Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary card booklets. 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.

  11. Average Number of Withdrawal Bleeding Days [Every 28-day cycle for 6 cycles]

    Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary card booklets. Participants documented whether vaginal bleeding was present, and if present, indicated whether it was considered to be spotting or bleeding. Withdrawal bleeding was defined as bleeding/spotting episode that started 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.

Title Number of Participants With an Occurrence of Early Withdrawal Bleeding
Description Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary card booklets. Participants documented whether vaginal bleeding was present, and if present, indicated whether it was considered to be spotting or bleeding. Early withdrawal bleeding was defined as any withdrawal bleeding that started before the current "expected bleeding period". Expected bleeding period: DRSP-EE: 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 6 cycles

Outcome Measure Data

Analysis 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.

Title Average Number of Breakthrough Bleeding/Spotting Days
Description Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary card booklets. 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 6 cycles
