Study summary

The objective of this study is to evaluate the performance of a miniaturized sleep apnea test, called NightOwl. The system consists of a sensor placed on the fingertip and a cloud-based analytics software. The sensor acquires accelerometer and photoplethysmographic data. The software derives actigraphy from the former, and blood oxygen saturation and peripheral arterial tone (PAT), among other features, from the latter. In order to assess NightOwl's performance, the investigators will compare the apnea hypopnea index (AHI) estimate, defined as the number of respiratory events per hour of sleep, derived by the NightOwl system, to the apnea-hypopnea index (AHI) obtained from manual analysis of the polysomnography (PSG), which is the gold standard for sleep apnea diagnosis. This study will be performed in a sleep lab environment.

    PSG and NightOwl

    During the study, for each execution day, all patients that have been scheduled for a PSG will be presented with the informed consent form. All recruited patients shall be a part of the study during which they wear the NightOwl Sensor while undergoing the PSG exam.

    Device: NightOwl

What researchers measure

Primary outcomes

  1. The Evaluation of the Level of Agreement (Classification Accuracy) Between Patient Categorization

    The evaluation of the level agreement (classification accuracy) between patient categorization (into sleep apnea severity categories) obtained by the NightOwl and those obtained by the PSG. This measure is calculated by dividing the number of participants on which both NightOwl and the PSG agree on the sleep apnea severity category by the total number of participants.

    Time frame: Through study completion, an average of 1 month.

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 Mar 2021 (actual). Primary completion is estimated for Sep 2022, 17 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 17 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 Sep 6, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
