Trial summary

Obstructive sleep apnea (OSA) is the most common type of sleep apnea. OSA affects an estimated 18-40 million adults and 0.7-3% of all children in the US. The marketplace currently does not have an affordable, easy-to-use, over-the-counter, home-based OSA screening device. Read more about this study

About this study

Official title: Wireless Sensor Patch for Reducing Barriers to In-home Sleep Apnea Screening

Obstructive sleep apnea (OSA) is the most common type of sleep apnea. OSA affects an estimated 18-40 million adults and 0.7-3% of all children in the US. The marketplace currently does not have an affordable, easy-to-use, over-the-counter, home-based OSA screening device. An affordable, available, FDA-approved and easy-to-use over-the-counter OSA screening tool would allow greater screening of at-risk individuals, especially in underserved communities with low socioeconomic status, hopefully encouraging a greater proportion of such individuals to seek treatment for their condition. The specific goal of this project is to compare the Zansors® micro sleep sensor screening device against gold-standard polysomnography to establish the device's preliminary validity to screen for OSA accurately.

Read the detailed description

Obstructive Sleep Apnea (OSA) results in tiredness, depression and fatigue, and has several associated common comorbidities. It is believed that over 80% of OSA remains undiagnosed. Poorer and disadvantaged communities are at higher risk for sleep disorders, including OSA, even after accounting for other risk factors. The gold-standard method for diagnosing OSA is in-laboratory polysomnography; however, this procedure is generally available only to patients with health insurance due to its high cost. As a result, communities at particularly high risk for OSA are less likely to have this serious sleep disorder appropriately diagnosed and treated.

An affordable, available, FDA-approved and easy-to-use over-the-counter OSA screening tool would allow greater screening of at-risk individuals, especially in underserved communities with low socioeconomic status, hopefully encouraging a greater proportion of such individuals to seek treatment for their condition. Zansors® has developed a bioengineered, semiconductor prototype that measures breathing and movement during sleep. It is a 1.5 x 2.5 x 0.2 inch wireless package using four key technologies:

  1. an adjustable microphone;
  2. a 3-axis accelerometer;
  3. embedded algorithms to measure sleep events; and
  4. acrylic adhesive.

The product will be designed as an FDA-approved over-the-counter device that the patient can wear during sleep and wake up with a color score of red, yellow, or green depending on their sleep apnea status. The features of this product include that it is home-based; easy to use; non-invasive; wireless; disposable; low cost ($20-50); and presents easily understandable test results. However, such a device must first be validated against gold-standard polysomnography.

The specific goal of this project is to compare the Zansors® micro sleep sensor screening device against gold-standard polysomnography to establish the device's preliminary validity to screen for OSA accurately.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Specificity

    Specificity of Zansors' device to detect apnea events compared to gold-standard polysomnography over an 8-hour period of sleep at 30-second intervals

    Measured: 8 hours

Secondary outcomes (3)
  1. Sensitivity

    Sensitivity of Zansors' device to detect apnea events compared to gold-standard polysomnography over an 8-hour period of sleep at 30-second intervals

    Measured: 8 hours

  2. Positive Predictive Value (PPV)

    PPV of Zansors' device to detect apnea events compared to gold-standard polysomnography over an 8-hour period of sleep at 30-second intervals

    Measured: 8 hours

  3. Negative Predictive Value (NPV)

    NPV of Zansors' device to detect apnea events compared to gold-standard polysomnography over an 8-hour period of sleep at 30-second intervals

    Measured: 8 hours

Questions about this trial

What is this clinical trial studying?

A study testing Zansors® sleep screening device in people with Obstructive Sleep Apnea, run by University of Michigan at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 26 Jul 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Specificity (time frame: 8 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jan 2023.
