Outcome Measures
Primary Outcome Measures
- Mean Change From Baseline in Z-scores of the Lumbar Spine (L2-L4) and Femoral Neck [Baseline and after cycle 26 (2 years)]
BMD was measured by a Dual Energy X-ray Absorptiometry (DEXA) machine. The Z-score measures the distance of the measured BMD value from the appropriate normal age matched population mean value in units of standard deviation of this population. More negative scores indicate less BMD compared to age matched population, & more positive scores indicate higher BMD compared to age matched population. The adjusted mean change from baseline to the after Cycle 26 visit of the Z-scores is estimated using a baseline-adjusted analysis of covariance (ANCOVA).
Secondary Outcome Measures
- Number of In-treatment Pregnancies (With +2 Day Window) Per 100 Woman Years of Exposure (Pearl Index) [2 years (26 cycles)]
Contraceptive efficacy parameter of this trial was the Pearl Index. 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.
- Number of Participants With an Occurrence of Breakthrough Bleeding/ Spotting [Every 28-day cycle for 26 cycles (2 years total)]
Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary cards. 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: LNG-EE group: 21-day period starting on Day 1 of the cycle; NOMAC-E2: 21-day period starting on Day 4 of the cycle.
- Number of Participants With an Occurrence of Absence of Withdrawal Bleeding [Every 28-day cycle for 26 cycles (2 years total)]
Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary cards. 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: LNG-EE group: 7-day period starting on Day 22 of the cycle; NOMAC-E2 group: 7-day period starting on Day 25 of the cycle and ending on Day 3 of the next cycle.
- Number of Participants With an Occurrence of Breakthrough Bleeding [Every 28-day cycle for 26 cycles (2 years total)]
Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary cards. 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: LNG-EE group: 21-day period starting on Day 1 of the cycle; NOMAC-E2: 21-day period starting on Day 4 of the cycle.
- Number of Participants With an Occurrence of Breakthrough Spotting (Spotting Only) [Every 28-day cycle for 26 cycles (2 years total)]
Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary cards. 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: LNG-EE group: 21-day period starting on Day 1 of the cycle; NOMAC-E2: 21-day period starting on Day 4 of the cycle.
- Number of Participants With an Occurrence of Early Withdrawal Bleeding [Every 28-day cycle for 26 cycles (2 years total)]
Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary cards. 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: LNG-EE group: 7-day period starting on Day 22 of the cycle; NOMAC-E2 group: 7-day period starting on Day 25 of the cycle and ending on Day 3 of the next cycle.
- Number of Participants With an Occurrence of Continued Withdrawal Bleeding [Every 28-day cycle for 26 cycles (2 years total) including one week after stopping treatment]
Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary cards. 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: LNG-EE group: 21-day period starting on Day 1 of the cycle; NOMAC-E2: 21-day period starting on Day 4 of the cycle.
- Average Number of Breakthrough Bleeding-Spotting Days [Every 28-day cycle for 26 cycles (2 years total)]
Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary cards. Participants documented whether vaginal bleeding was present, and if so, indicated whether it was considered to be spotting or bleeding. Breakthrough bleeding/spotting was defined as any bleeding/spotting episode that occurred during the "expected non-bleeding period" that was neither an early nor a continued withdrawal bleeding. Expected non-bleeding period: LNG-EE: 21-day period starting on Day 1 of the cycle; NOMAC-E2: 21-day period starting on Day 4 of the cycle.
- Average Number of Withdrawal Bleeding-spotting Days [Every 28-day cycle for 26 cycles (2 years total)]
Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary cards. 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: LNG-EE group: 7-day period starting on Day 22 of the cycle; NOMAC-E2 group: 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 Breakthrough Bleeding |
---|---|
Description | Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary cards. 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: LNG-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 26 cycles (2 years total) |
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 cards. Participants documented whether vaginal bleeding was present, and if so, indicated whether it was considered to be spotting or bleeding. Breakthrough bleeding/spotting was defined as any bleeding/spotting episode that occurred during the "expected non-bleeding period" that was neither an early nor a continued withdrawal bleeding. Expected non-bleeding period: LNG-EE: 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 26 cycles (2 years total) |
Outcome Measure Data
Analysis 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. |
