Study summary

Prospective validation study of the NightOwl, a Type IV home sleep apnea test (HSAT), compared to a traditional Type I and a Type IV sleep monitor.

Read the detailed description

The purpose of this prospective validation study is the evaluation of the accuracy of the NightOwl HSAT to derive parameters relevant for the diagnosis of sleep apnea. The NightOwl HSAT comprises a finger or forehead mounted sensor and an automated analytics software. The sensor measures double-wavelength photo-plethysmography and accelerometry. The analytics software automatically interprets the sensor data and derives a measure of sympathetic activation of the autonomic nervous system, oxygen saturation, instantaneous pulse rate and activity. For each patient in the cohort, the AHI derived by the NightOwl will be compared to that of the Type I sleep monitor (in-lab PSG), which will acquire data simultaneously during the diagnostic night of the patient referred to the sleep lab for a polysomnography. On a randomly selected subset of patients, a Type IV sleep monitor will additionally be applied for comparison of its automated AHI derivation to that of the NightOwl.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jun 2017 (actual). Primary completion is estimated for Sep 2019, 26 months after the start.

Of 68 industry-sponsored interventional studies with no phase under Sleep Apnea Syndromes, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 18. This study's planned 26 months is above that.

Counting every sponsor, half of 268 studies reached it within 26 months; a quarter within 11 and three quarters within 56.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 21, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
