Pharmacokinetics of Implanon in Obese Women
NCT00724438 · View on ClinicalTrials.gov ↗
Study Summary
Prior studies examining the pharmacokinetics, safety, and efficacy of the new etonogestrel-containing single rod implantable contraceptive device, Implanon, did not include women who exceeded 130% of ideal body weight. Yet, as these women comprise a significant portion of the U.S. population, studies of Implanon in obese women are essential. The proposed study represents an important first step in addressing the lack of data on Implanon in obese women. We aim to examine the pharmacokinetics of Implanon in obese women during the first 6 months of use and to provide data on the acceptability, side effect profile, and ease of insertion, palpation, and removal in these women. We also aim to collect samples for future validation studies of the use of the blood spot (finger-stick blood sample on filter paper) as a method of determining plasma etonogestrel.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00724438
The ClinicalTrials.gov registry entry for NCT00724438 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 18 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Chicago, which has 846 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Obesity appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00724438 reports 1 study location spanning 1 distinct geographic area — top geographies include Illinois. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
