Brief Summary:
The objective of this study is to determine the safety and effectiveness of the aerSleep® II device for treatment of moderate to severe Obstructive Sleep Apnea (OSA) over 24 weeks of home use in spontaneously breathing adult subjects who are intolerant of Continuous Positive Airway Pressure (CPAP) therapy.

Condition or disease Intervention/treatment Phase
Sleep Apnea, Obstructive Apnea, Sleep Device: aerSleep II Not Applicable

Detailed Description:
This is a multi-center, single-arm, prospective, observational intervention study to determine the safety and effectiveness of the aerSleep II System. Up to 900 subjects will be enrolled at up to 30 study sites in the United States and outside the United States to ensure that approximately 79 subjects who are termed initial responders can be evaluated after 24 weeks of home use with the aerSleep II device. As part of screening and prior to intervention, home sleep testing will be performed to establish baseline apnea-hypopnea index (AHI). Subjects meeting study criteria will wear the aerSleep II device at home. After a 1-week period of acclimation, subjects will have a second HST (HST #2). Initial responders with a ≥50% reduction in AHI from baseline with an AHI <20/hour will be continued on home treatment. Non-responders will be discontinued from the study. After 12 weeks, subjects will have an interim home sleep study. After 24 weeks of home use, subjects will have HST #4 to determine the primary effectiveness endpoint.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 900 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Study Using Negative Pressure to Reduce Apnea (SUPRA)
Actual Study Start Date : November 29, 2021
Estimated Primary Completion Date : September 2024
Estimated Study Completion Date : September 2024

Arm Intervention/treatment
Experimental: aerSleep II
Use of aerSleep II device to provide continuous external negative pressure to treat moderate to severe OSA in spontaneously breathing subjects who are intolerant of CPAP
Device: aerSleep II
Continuous negative external pressure (cNEP) system that maintains an open airway by applying negative pressure to the anterior neck via a soft silicone collar

Primary Outcome Measures :
  1. Sustained response to aerSleep II therapy at 24 weeks [ Time Frame: 24 weeks ]
    The primary effectiveness endpoint is to demonstrate that a majority of adult subjects who are initial responders to aerSleep II therapy experience a change of at least 50% of their baseline AHI with an AHI rate less than 20 per hour at the final home sleep test at 24 weeks.

  2. Adverse Device Effects [ Time Frame: 24 weeks ]
    The primary safety endpoint is to characterize the adverse device effects experienced throughout the study.

Secondary Outcome Measures :
  1. ODI change [ Time Frame: 24 weeks ]
    Demonstrate a change in Oxygen Desaturation Index (ODI) at HST #4 compared to baseline HST for initial responders

  2. AHI change from baseline for all subjects that acclimate to the aerSleep II device [ Time Frame: 24 weeks ]
    Determine the proportion of subjects that acclimate to the device that exhibit a change in AHI after 24 weeks of home use with the aerSleep II device

  3. Change in sleep disturbance from baseline as measured by Patient Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance questionnaire [ Time Frame: 24 weeks ]
    Determine the change in sleep disturbance at the end of the study compared to baseline using the validated PROMIS Short Form Sleep Disturbance 8b questionnaire

  4. Change in sleep impairment from baseline as measured by PROMIS Sleep Sleep-Related Impairment questionnaire [ Time Frame: 24 weeks ]
    Determine the change in sleep impairment at the end of the study from baseline as measured by the validated PROMIS Short Form Sleep-Related Impairment 8a questionnaire

  5. Change in sleep from baseline as measured by Patient Global Impression Scale questionnaire [ Time Frame: 24 weeks ]
    Determine any change in sleep at the end of the study from baseline as measured by the Patient Global Impression Scale questionnaire

  3. Prior documented diagnosis of OSA by means of a polysomnography (PSG) test or home sleep test (HST)
  4. Documented evidence from a screening HST following consent to demonstrate:

    1. AHI 15 - 50/hour
    2. >80% of the apneas and hypopneas are obstructive
  5. Previous treatment attempt with CPAP resulting in failure to treat or discontinuation due to intolerance, subject choice, or struggle to use CPAP

Exclusion Criteria:

  1. Known sleep disorder other than OSA, such as narcolepsy, restless leg syndrome, idiopathic hypersomnolence or chronic insomnia
  2. Craniofacial abnormalities that may be contributing to OSA
  3. Previous surgery, injury, or radiation to the neck which, in the Investigator's judgment, could interfere with collar fit or comfort
  4. Excessive hair or beard in the area of the neck where the collar will be placed, and/or unwillingness to shave that area for the duration of this study
