Mirena Extended Use Study

Purpose of the study

The purpose of this study is to research extended use of the Mirena® IUS. Currently, the Mirena® IUS is approved to prevent pregnancy for 5 years. This study will help researchers assess if the Mirena® IUS is effective and safe beyond 5 years and up to 8 years of use. Additionally, researchers hope to learn more about the safety and tolerability of the study IUS.

PI name: John Partridge

Why is the study being done: Mirena® IUS is a highly effective contraceptive method that is currently approved for use in the U.S. for up to 5 years. In addition, Mirena® has been shown to reduce menstrual blood loss. Researchers aim to assess if Mirena® is an effective method of contraception for up to 8 years. Depending on the results, this may allow clinicians to recommend a longer interval between the IUS placements in women. Mirena® can also lessen menstrual blood loss in women who have heavy menstrual flow. Therefore, a sub-study will be conducted to assess whether the effect of Mirena® on menstrual blood loss is maintained beyond 5 years, and up to 8 years of use.
