What is NCT02267616, and how is it related to Nexplanon?
NCT02267616 is a clinical trial identifier used in ClinicalTrials.gov. It’s commonly cited in connection with studies evaluating how long Nexplanon can remain effective after insertion (often discussed alongside “extensions” of the approved/standard duration). The “extension” framing typically means participants stayed in follow-up beyond the original observation window to gather additional duration and safety data.
Where can I find the publication that reports the Nexplanon duration extension results?
The specific publication tied to NCT02267616 is usually referenced by searching the trial record on ClinicalTrials.gov and then checking the “Publications” section. That is the fastest way to confirm the exact journal article (title, authors, year) that reports results from the extension cohort for Nexplanon/Nexplanon-related study endpoints.
If you want, share the study’s full title from the NCT02267616 record (or paste the ClinicalTrials.gov “Brief Title”), and I can help you match it to the correct journal publication and key results.
Why do “extension” studies for Nexplanon matter for users and clinicians?
Extension studies collect longer-term evidence that helps support guidance such as “use beyond X years” (or clarify limits), while also tracking adverse events and method-related outcomes over extended follow-up. These papers are often cited when clinicians counsel patients about effectiveness windows and when regulators/health authorities consider label updates.
How to verify you have the right “extension” paper (common mix-ups)
Searchers sometimes conflate:
- the original Nexplanon pivotal/registration studies,
- follow-on or long-term observational data,
- and extension trials with different follow-up endpoints (pregnancy outcomes vs. overall safety).
To avoid mixing them up, confirm that the paper explicitly:
- lists NCT02267616 in the Methods/Methods footnotes or trial registration section, or
- cites the ClinicalTrials.gov identifier in the abstract/full text.
What should you look for in the NCT02267616 publication?
In Nexplanon duration-extension papers, readers typically focus on:
- the effectiveness endpoint (pregnancy incidence and timing),
- how long participants were followed (duration beyond the standard period),
- safety outcomes (bleeding-related events, adverse events),
- and the population studied (region, age range, number of participants retained).
If you paste the abstract or the Results section from the publication you found, I can help interpret the key numbers and what they imply for the “extension” duration claim.

I don’t have enough provided information to cite the exact Nexplanon extension publication tied to NCT02267616 without the trial’s ClinicalTrials.gov entry text (or the publication title/DOI). If you share the link to the NCT02267616 record or the paper you found, I can pinpoint the correct citation precisely.
