Study summary

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

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 benchmark HSAT will additionally be applied for comparison of its automated AHI derivation to that of the NightOwl.

What researchers measure

Primary outcomes

  1. Apnea-Hypopnea Index (AHI)

    Comparison of the AHI derived from the NightOwl HSAT to that of the benchmark PSG and HSAT monitors.

    Time frame: For each included patient, the outcome measure will be assessed immediately after analysis of that patient's data by the NightOwl HSAT software

Secondary outcomes

  1. Sleep-wake discrimination

    Comparison of the sleep-wake discrimination derived from the NightOwl HSAT to that of the benchmark PSG and HSAT monitors.

    Time frame: For each included patient, the outcome measure will be assessed immediately after analysis of that patient's data by the NightOwl HSAT software

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 Aug 2018 (actual). Primary completion is estimated for Sep 2019, 13 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 13 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 Aug 17, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
