Trial Outcomes & Findings for Dose-finding Study for the Ultralow-dose Levonorgestrel Intrauterine Contraceptive System (LCS) (NCT NCT00185380)

NCT ID: NCT00185380

Last Updated: 2015-06-10

Results Overview

The 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 under risk of getting pregnant.

Participant Flow

Parous or nulliparous women in good general health and in need of contraception were recruited from medical clinics between April and Nov 2005.

Most screening failures were in-/exclusion criteria not met and over-screening. Randomized: 742 women, Treated: 738 women. Full analysis set (FAS), safety analysis set (SAF) and per protocol analysis set (PPS) were identical (738 subjects).

PRIMARY outcome

Timeframe: Up to 3 years

Population: All randomized women with a successful insertion were analyzed according to the treatment actually received and were included in the FAS, which was the set used for all safety and efficacy analyses. The PPS was identical to the FAS.

The 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 under risk of getting pregnant.

SECONDARY outcome

Timeframe: Up to 3 years

Population: The analysis was performed on the FAS (all subjects who had an IUS inserted).

The numbers of subjects with partial or total IUS expulsions (device displaced from its correct position within the uterus) were to be given by treatment.

SECONDARY outcome

Timeframe: day 1 to day 90

Population: The analysis was performed on the FAS (all subjects with an insertion) and included subjects with bleeding or spotting or both.

Subjects kept a bleeding diary and recorded any bleeding every day by category: none, spotting, light, normal or heavy. Any missing data were obtained by direct questioning.
