Levonorgestrel Contraceptive Intrauterine Systems (LCS) Pearl Index Study

December 1, 2016 updated by: Bayer

Multi-Center, Open-Label, Randomized Study to Assess the Safety and Contraceptive Efficacy of Two Doses ( in vitro12 µg/24h and 16 µg/24h) of the Ultra Low Dose Levonorgestrel Contraceptive Intrauterine Systems (LCS) for a Maximum of 3 Years in Women 18 to 35 Years of Age and an Extension Phase of the 16µg/24h Dose Group (LCS16 Arm) up to 5 Years

This is a study on a new low dose levonorgestrel contraceptive intrauterine systems (LCS). The purpose of the study is to investigate which of the 2 administered doses is the lowest effective intrauterine dose of Levonorgestrel (LNG) administered via the LCS for contraception during 3 years. The study was amended: the LCS16 arm will be extended up to 5 years

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pearl Index up to 3 Years
Time Frame: Up to 3 years
The unadjusted Pearl Index (PI) is defined as the number of pregnancies per 100 woman years. The 3-year PI was obtained by dividing the number of pregnancies that occurred during the first three years of treatment by the time (in 100 women years) that the women were at risk of getting pregnant.
Up to 3 years
Pearl Index for LCS16 up to 5 Years
Time Frame: Up to 5 years
The unadjusted Pearl Index (PI) is defined as the number of pregnancies per 100 woman years.
