Summary

This is a Phase 3, randomized, open-label, multicenter evaluation of the efficacy of a levonorgestrel-releasing intrauterine system (LnG20). a marketed levonorgestrel-releasing intrauterine system (Mirena) will be included to act as an infomartive comparator.

eligible subjects 16-35 years of age will be randomized to one of two iuS arms to include approximately 1900 subjects using LnG20 and 400 subjects using Mirena. The randomization will be performed in an approximate 4:1 ratio. an additional 150 eligible females 36-45 years of age will receive LnG20 as part of a non-randomized cohort. We plan to consent 75 women age 18-45 years at uT Southwestern in order to have 60 subjects who will participate in the protocol.
The non-randomized cohort for LnG20 for ages 36-45 and the Mirena cohort are now completed and close to enrollment.
