Nexplanon Extended Use study

Why is this clinical trial being done?
The etonogestrel implant is approved for use to prevent pregnancies for up to 3 years. It has not been approved to use for more than 3 years. The purpose of this clinical trial is to find out if using the implant for more than 3 years:

  • Is safe
  • Continues to prevent pregnancy
  • Affects the menstrual cycle (periods)
  • Causes problems when it is removed.


Who can join this clinical trial?
You may be able to join this clinical trial if you:
• Have an etonogestrel implant that was inserted 34–36 months ago (about 3 years ago)
• Are willing to continue to use the etonogestrel implant for an additional 24 months and do not intend to use any other form of contraception (for example, condoms)
• Are between 18 and 35 years old
• Are able to get pregnant


What will I be asked to do if I join?
If you join, you will be in the trial for about 27 months (a little over 2 years). You will:
• Visit the trial site 11 times for the trial doctor and staff to check on your health and collect information for research purposes
• Complete some trial-related activities between visits to the trial site, such as using an electronic diary (eDiary) to answer questions daily
You will not be given a trial drug or treatment. This trial is researching the implant you already have.
