Recruiting studies
- NCT06926036Recruiting
Sound therapy for sleep apnea
This study aims to test whether a special sound technique can help people with sleep apnea sleep better. It may offer a new way to manage the condition without needing a CPAP machine.
Chicago, IllinoisAges 18–60 - NCT05939934Recruiting
Test a mouth device for sleep apnea after stopping CPAP
This study looks at whether a mandibular advancement device (a fitted mouthpiece) can control sleep apnea when you temporarily stop CPAP. It’s mainly for people who have been using CPAP for over a year but are now willing to try the mouth device.
AngersAges 18–75 - NCT05575401Recruiting
Track surgery results in kids getting tonsil removal
This trial looks at how well a specific throat surgery technique works in children who are having their tonsils removed (with or without removing adenoids). It may help improve how doctors choose and perform surgery for safer, better recovery.
Murrieta, CaliforniaAges 3–17 - NCT06848647Recruiting
Treating sleep apnea to improve metabolism
This study tests whether treating sleep apnea with CPAP improves your body's metabolism (how your body uses energy). It's for people who have sleep apnea and are about to start CPAP therapy.
Uppsala, Uppsala CountyAges 18 years+ - NCT06828835Recruiting
Sleep study for caregivers of children with breathing problems
This study helps parents of children with sleep-related breathing problems (like snoring or pauses in breathing) who have been referred to a specialist. It offers support and guidance over 12 months to make it easier to get the care your child needs.
Charleston, South CarolinaAges 2–12 - NCT07047092RecruitingPhase 3
CPAP vs. NIV for sleep apnea in COPD after breathing failure
This trial compares two breathing devices (CPAP and NIV) for people with both COPD and sleep apnea who recently needed breathing help in the hospital. The goal is to see which device works better at preventing future breathing emergencies.
ParisAges 18–84 - NCT05558501RecruitingPhase 1/Phase 2
Intermittent low-oxygen therapy for sleep apnea and health risks
This early-stage study tests a treatment that briefly reduces oxygen during sleep to improve “plasticity,” with the goal of helping people with obstructive or mixed sleep apnea. It also looks at related conditions like high blood pressure and pre-diabetes or cholesterol problems, especially in people who haven’t tried CPAP yet.
Detroit, MichiganAges 30–60 - NCT06994247Recruiting
Boosting CPAP use in severe sleep apnea
This study tests whether motivation and psychological support can help people with severe sleep apnea use their CPAP machine more consistently over three months.
Split, DalmatiaAges 18 years+ - NCT02703207Recruiting
Sleep apnea and COPD effects in older veterans
This study looks at how sleep apnea affects thinking skills and overall health in older veterans who also have COPD. It may help researchers understand what changes to target to improve daytime functioning and wellbeing.
Detroit, MichiganAges 60–89 - NCT06711159Recruiting
Searching for a biomarker of sleepiness in severe sleep apnea
This study looks for a biological marker of severe daytime sleepiness in people with severe obstructive sleep apnea who haven't started breathing machine treatment yet. It may help doctors better understand and treat sleepiness in the future.
Koege, Regional ZealandAges 18 years+ - NCT06974851RecruitingPhase 3
Study of HRS9531 for sleep apnea and obesity
This trial tests an injectable medication (HRS9531) to see if it helps people with both obstructive sleep apnea and obesity. It compares the drug to a placebo (no active medicine) to check safety and effectiveness.
Beijing, Beijing MunicipalityAges 18–75 - NCT03255408RecruitingPhase 1/Phase 2
Sleep study testing breathing and blood flow in healthy adults
This study looks at how your brain blood flow and breathing change during sleep under normal oxygen and reduced oxygen. It will only include healthy adults so researchers can learn what “intermittent hypoxia” does to the body in people without medical problems.
Calgary, AlbertaAges 18–45 - NCT02784977Recruiting
Sleep apnea study using a national sleep database
This study collects information from adults who are getting a sleep test because obstructive sleep apnea is suspected. It helps researchers better understand sleep apnea and who develops it, without giving a new treatment.
IstanbulAges 18–80 - NCT07792746Recruiting
Sleep apnea markers and use of CPAP therapy
This study looks at whether certain markers in sleep apnea patients can predict how well they will stick with CPAP (a mask that helps you breathe at night). If you're newly diagnosed and about to start CPAP, this could help personalize your care.
MontpellierAges 18 years+ - NCT06089096Recruiting
Sleep apnea and memory in people with mild memory problems
This study looks at whether sleep apnea (pauses in breathing during sleep) is linked to thinking and memory in people who have mild memory problems. You will do a home sleep test and take memory tests to help researchers find this connection.
Hong KongAges 18 years+ - NCT05978505RecruitingPhase 2
Reboxetine for sleep apnea after ENT surgery
This study tests if the medication reboxetine helps reduce sleep apnea symptoms after planned upper airway surgery. It may be a good fit if you have sleep apnea and are having surgery on your nose or throat.
Bedford Park, South AustraliaAges 18 years+ - NCT03948373Recruiting
Study of sleep apnea patients with normal blood pressure
This study is looking at a specific sleep-related condition (obstructive sleep apnea) in adults whose blood pressure is not high, and how their blood pressure rhythm changes over the day. If you have sleep apnea, participating could help researchers understand patterns that may affect long-term health.
LleidaAges 18–100 - NCT07214636Recruiting
Apnea therapy exercise app for sleep apnea patients
This trial tests a new exercise app to help people with sleep apnea. It looks at whether using a smartphone or tablet app can improve symptoms for those already using a CPAP machine.
Istanbul, Göztepe NeighborhoodAges 18–65 - NCT07176767Recruiting
Sleep study on insomnia and mask use in kids
This study looks at how insomnia affects how well children and teenagers use their breathing mask (PAP therapy) for sleep apnea. It aims to find ways to help kids stick with their treatment.
Vancouver, British ColumbiaAges 8–18 - NCT07136909Recruiting
Testing a sleep apnea questionnaire for French children
This study is testing a French questionnaire (OSA-18) to see if it helps screen for sleep apnea in kids. It may lead to easier detection of breathing problems during sleep.
Bron, RhôneAges 4–17 - NCT07009535Enrolling by invitation
Sleep apnea risk and orthodontic issues in children
This study looks at how narrow upper jaws (maxillary constriction) relate to sleep apnea in children with mixed teeth. It aims to understand if dental problems affect breathing during sleep and guide future treatments.
Pavia, LombardyAges 6–12 - NCT06786117Enrolling by invitation
Swallowing therapy study for sleep apnea patients
This study tests whether daily swallowing exercises can help people with sleep apnea who cannot tolerate CPAP therapy. It compares three groups: healthy people, successful CPAP users, and those who have difficulty using CPAP.
Cleveland, OhioAges 40–70 - NCT06789770Recruiting
Nasal vs mouth breathing during drug-induced sleep
This study compares how breathing through the nose versus mouth affects sleep, using both natural and medication-induced sleep. It may help people with sleep apnea understand their breathing patterns better.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06763549Enrolling by invitation

- Yes. Clin2 currently lists 288 recruiting apnea, obstructive studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a apnea, obstructive trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a apnea, obstructive trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
