Allergan and Medicines360 announced that the Food and Drug Administration (FDA) has approved Liletta (levonorgestrel-releasing intrauterine system) for the prevention of pregnancy for up to 4 years. 

The FDA’s approval of the supplemental New Drug Application (sNDA) was based on efficacy and safety data from the ongoing Phase 3 ACCESS IUS trial (n=1,751). The study showed Liletta was >99% effective in preventing pregnancy across a varied demographic with differing age, body mass index, parity, and race.

Liletta, a hormone-releasing system, was initially approved in February 2015 for the prevention of pregnancy for up to 3 years. It gained additional FDA approval in January 2016 for the single-handed inserter.
