Pragmatic Obstructive Sleep Apnea Weight Loss Trial Assessing Effectiveness and Reach
NCT05104450 · View on ClinicalTrials.gov ↗
Study Summary
Prevalent obesity related conditions like obstructive sleep apnea (OSA) represent an important opportunity to improve population health. OSA reduces quality of life and is associated with greater risk for cardiovascular disease. Although obesity is the single greatest reversible risk factor for OSA, patients with OSA and obesity rarely receive weight loss care to reverse OSA and other serious comorbidities. Efficacy trials reinforce that time and resource intensive lifestyle-based weight loss programs improve weight and physiologic measures of OSA severity (apnea hypopnea index, AHI). However, there are barriers to translating these findings into meaningful gains for population health. To meet these challenges, the investigators propose a pragmatic trial of proactively offering a remote video-based and self-directed lifestyle-based weight loss intervention with remote coaching to patients with OSA. The investigators primary aim is to test the effectiveness of a proactively delivered and pragmatic lifestyle intervention to improve co-primary endpoints of sleep-related quality of life and weight among patients with OSA and obesity. Secondarily, the investigators will compare additional outcomes between groups including cardiovascular risk scores, sleep symptoms, AHI, well-being, and global ratings of change. Finally, the investigators will also conduct an implementation process evaluation informed by the RE-AIM framework to identify barriers and facilitators to widespread implementation. The investigators will identify patients with OSA and obesity nationwide (n=696) in VA using data from the VA's Corporate Data Warehouse (CDW), and the investigators will contact potentially eligible patients. After confirming eligibility and consent, the investigators will randomly assign subjects to receive the study's lifestyle intervention or usual care alone. The study uses CDW to assess weight change. Subjects will complete questionnaires at baseline at 3, 12 and 21 months afte

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05104450
The ClinicalTrials.gov registry entry for NCT05104450 describes a study currently listed as completed. 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 696 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is VA Office of Research and Development, which has 1,863 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 1 intervention — of which lifestyle intervention 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: NCT05104450 reports 1 study location spanning 1 distinct geographic area — top geographies include Washington. 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.
