NCT05428839 · View on ClinicalTrials.gov ↗
Study Summary
This study is an exploratory, multicenter study of up to 300 subjects diagnosed with obstructive sleep apnea who are being evaluated for airway surgery. Subjects will undergo standard evaluation for airway surgery as part of standard of care. In addition to the standard airway assessment, a simple, non-invasive measurement of the width of the inside of each subjects mouth will be performed. This measurement takes 2-3 minutes to perform.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05428839
The ClinicalTrials.gov registry entry for NCT05428839 describes a study currently listed as recruiting. It is categorized as NA, 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 300 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Inspire Medical Systems, which has 34 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Sleep Apnea, Obstructive appearing as the primary indexed condition, and to 1 intervention — of which Pharyngeal width measurement is the first listed. 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: NCT05428839 reports 10 study locations spanning 8 distinct geographic areas — top geographies include Pennsylvania, Arizona, 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.
