About this study

Official title: A Feasibility Study to Determine the Effects of a Novel Mattress Support for Treatment of Positional Obstructive Sleep Apnea at Home

  1. Determine the effects of a mattress support (Wave 4.3) that promotes the avoidance of supine airway position at home on the apnea-hypopnea index (AHI) in patients with positional obstructive sleep apnea (OSA).
  2. Determine the effects of Wave 4.3 on subjective measures of sleepiness and daytime function in patients with positional OSA.
  3. Determine the effects of Wave 4.3 on subjective measures of sleep quality in patients with positional OSA.
Read the detailed description

This is a preliminary single-arm study. The study will last up to 4 weeks including the screening period. Subjects will sleep using the mattress support at home for two consecutive weeks.

Outcome measures will include: AHI derived from HSAT (primary outcome), oxygen desaturation index (ODI), Epworth Sleepiness Scale (ESS) score, Functional Outcomes of Sleep Questionnaire (FOSQ), Visual Analog Scale (VAS) and questionnaire assessments of sleep quality, and actigraphic sleep measures. Subjects will also keep a sleep diary every night for the duration of the study. Subjects will be asked about their bed partners' report on snoring and witnessed apneas.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Wave 4.3Device

    The Wave 4.3 mattress support is an insert, placed underneath the user's existing mattress, that when inflated increases the longitudinal incline of the mattress support, increasing in inclination in the direction of the head of the bed. The resulting mattress contours are such that the mattress has a lateral inclination of approximately 15 degrees in the head section and 10 degrees in the torso section. In addition to the features allowing the user to activate and deactivate creation of this Graduated Lateral RotationTM orientation, this device has sensors and monitoring system allowing for remotely monitoring the status of the system, including confirming that the supports are achieving the prescribed support angles, and that the system is working as planned.

What is being measured

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

  1. Apnea-Hypopnea Index Difference Between Two Nights

    Apnea-Hypopnea Index derived from Home Sleep Test. The apnea-hypopnea index (AHI) is the combined average number of apneas and hypopneas that occur per hour of sleep between two nights. AHI<5 is indicative of no sleep apnea, AHI 5-15 is indicative of mild sleep apnea, AHI 15-30 is indicative of moderate sleep apnea, AHI>30 is indicative of severe sleep apnea. The minimum AHI is 0, and there is no maximum. A higher score means a worse outcome. Subscales are not used to compute the value. The difference was calculated based on the value at night 1 minus the value at night 2 (converted to a positive value if the difference created a negative value). The mean value was calculated by adding the difference based on the total number of participants.

    Measured: 2 nights

Secondary outcomes (4)
  1. Oxygen Desaturation Index Difference Between Two Nights

    Oxygen Desaturation Index calculated based on the average between two nights measured. Desaturation episodes are generally described as a decrease in the mean oxygen saturation of ≥4% (over the last 120 seconds) that lasts for at least 10 seconds. ODI values can range from 0 to greater than 30. A higher score means a worse outcome. Subscales are not used to compute the value. The difference was calculated based on the value at night 1 minus the value at night 2 (converted to a positive value if the difference created a negative value). The mean value was calculated by adding the difference based on the total number of participants.

    Measured: 2 nights

  2. Epworth Sleepiness Score

    A subjective measure of sleepiness on average based on the total score. The score ranges from a minimum of 0 to a maximum of 24. A higher score means a worse outcome. Subscales are not used to compute the value. The difference was calculated based on the value at visit 1 minus the value at visit 4 (converted to a positive value if the difference created a negative value). The mean value was calculated by adding the difference based on the total number of participants.

    Measured: Completed at Visit 1 and Visit 4 (~5 minutes)

  3. Functional Outcomes of Sleep Questionnaire Score

    A subjective measure of sleepiness on daytime function with an average of the total score. The score ranges from a minimum of 0 to a maximum of 20. A higher score means a better outcome. Subscales are not used to compute the value. The difference was calculated based on the value at visit 2 minus the value at visit 4 (converted to a positive value if the difference created a negative value). The difference was calculated based on the value at visit 2 minus the value at visit 4 (converted to a positive value if the difference created a negative value). The mean value was calculated by adding the difference based on the total number of participants.

    Measured: Completed at Visit 2 and Visit 4 (~5 minutes)

  4. Visual Analog Scale Score

    A subjective measure of sleepiness with the average of the total score. The score ranges from a minimum of 0 to a maximum of 100. A higher score means a better outcome. Subscales are not used to compute the value. The difference was calculated based on the value at visit 2 minus the value at visit 4 (converted to a positive value if the difference created a negative value). The mean value was calculated by adding the difference based on the total number of participants.

    Measured: Completed at Visit 2 and Visit 4 (~5 minutes)

Questions about this trial

What is this clinical trial studying?

A study testing Wave 4.3 in people with Sleep Apnea, Obstructive, run by Ohio State University 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 10 inclusion and 16 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: stopped early, as of the sponsor's last update on 16 Mar 2021. 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 16 Mar 2021). 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?

Apnea-Hypopnea Index Difference Between Two Nights (time frame: 2 nights). 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 16 Mar 2021.
