Bright Light Therapy for OSA
NCT05917119 · View on ClinicalTrials.gov ↗
Study Summary
Persistent daytime symptoms of sleepiness in individuals with obstructive sleep apnea (OSA) who are using Continuous Positive Airway Pressure (CPAP) are associated with adverse long term medical and functional outcomes. Supplementary exposure to bright light has beneficial effects on sleep quality and daytime vigilance in healthy individuals and it has been increasingly applied in a variety of sleep and neuropsychiatric conditions. This study will explore the role of Bright Light Therapy (BLT), a well-established non-pharmacological intervention for circadian disturbances, for the treatment of residual daytime symptoms of OSA which do not respond to CPAP. BLT will be delivered via therapy glasses in a cross-over design, where each participant will be exposed to active treatment and sham treatment (4 weeks in each arm) in a randomized order. The hypothesis is that participants will demonstrate improvements in the variables of interest during the four-week active treatment portion of the eight-week crossover study, compared to the four-week sham treatment portion.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05917119
The ClinicalTrials.gov registry entry for NCT05917119 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 60 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 1 condition, with Obstructive Sleep Apnea appearing as the primary indexed condition, and to 2 interventions — of which BLT 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: NCT05917119 reports 1 study location spanning 1 distinct geographic area — top geographies include Pennsylvania. 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.
