Brief Summary

The primary purpose of this study is to assess contraceptive efficacy, vaginal bleeding patterns (cycle control), general safety and acceptability of the nomegestrol acetate-estradiol (NOMAC-E2) combined oral contraceptive (COC) in a large group of women aged 18-50 years.

Contraception

Outcome Measures

Primary Outcomes (2)

• Number of In-treatment Pregnancies (With +2 Day Window) Per 100 Woman Years of Exposure (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.

  1 year (13 cycles)

• Number of In-treatment Pregnancies (With +14 Day Window) Per 100 Woman Years of Exposure (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 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.

  1 year (13 cycles)

Secondary Outcomes (8)

• Number of Participants With an Occurrence of Breakthrough Bleeding/Spotting

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

• Number of Participants With an Occurrence of Absence of Withdrawal Bleeding

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

• Number of Participants With an Occurrence of Breakthrough Bleeding

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

• Number of Participants With an Occurrence of Breakthrough Spotting (Spotting Only)

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

• Number of Participants With an Occurrence of Early Withdrawal Bleeding

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