Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with moderate to severe obstructive sleep apnea who are not being treated now. They wear the C-Lift device for one night in a sleep lab.

Age
18 Years and older
Sex
All
Disease stage
Moderate to severe obstructive sleep apnea (≥16 AHI events per hour, meaning breathing pauses per hour of sleep).
Earlier treatment
People must have failed or refused CPAP before. They cannot be in treatment for sleep apnea now, or in the 2-weeks before the sleep study. They cannot have had surgery for sleep apnea, such as hypoglossal nerve stimulation (tonsil removal is allowed).

Main reasons for not taking part

  • Mild sleep apnea (AHI<15 events per hour), another sleep disorder such as insomnia, or other breathing problems in sleep such as central sleep apnea
  • Neck spine injury or surgery in the past, or neck circumference >20 inches
  • Getting oxygen therapy now, or baseline oxygen level <90%
  • Being pregnant now, or a history of substance abuse
  • Regular use of medicines that affect breathing in sleep, such as opioids, benzodiazepines, gabapentin, antipsychotics or stimulants

About the trial

What the trial wants to find out

The goal of this clinical trial is to evaluate the efficacy of the C-Lift Device as a non-invasive treatment for Sleep Disordered Breathing (SDB) within the population of adults diagnosed with moderate to severe Obstructive Sleep Apnea (OSA), who are not currently being treated with a Continuous Positive Airway Pressure (CPAP) device or other intervention.

This study aims to answer 2 main questions: "Will C-Lift demonstrate a qualitative improvement in a participant's perception/description of their sleep-quality?" And, "Will wearing the C-Lift Device overnight show a quantitative improvement in a participant's oxygen saturation?"

The group in the trial

  • C-LiftTreatment being tested

    Participants will wear the C-Lift during sleep for one night in a sleep lab.
