What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of In-treatment Pregnancies (With +2 Day Window) Per 100 Woman Years of Exposure (Pearl Index)
Time Frame: 1 year (13 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 women years) that the women were under risk of becoming pregnant.
|
1 year (13 cycles)
|
Number of In-treatment Pregnancies (With +14 Day Window) Per 100 Woman Years of Exposure (Pearl Index)
Time Frame: 1 year (13 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 period of 14 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.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With an Occurrence of Breakthrough Bleeding/Spotting
Time Frame: Every 28-day cycle for 13 cycles (one year total)
|
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.
|
Every 28-day cycle for 13 cycles (one year total)
|
Number of Participants With an Occurrence of Absence of Withdrawal Bleeding
Time Frame: Every 28-day cycle for 13 cycles (one year total)
|
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.
|
Every 28-day cycle for 13 cycles (one year total)
