Recruiting studies
- NCT05050383Recruiting
Study testing obstruction patterns to guide CPAP alternatives
This study looks at how breathing passages narrow during sleep to better understand obstruction patterns. It may help people who are being considered for alternatives to CPAP (a common breathing device) for sleep-disordered breathing.

CPAP for high cholesterol and sleep apnea
This study tests if CPAP therapy can improve cholesterol and uric acid levels in people with both high cholesterol and moderate to severe sleep apnea. It may help if you have sleep apnea and are looking for additional ways to manage your lipid levels.
Coslada, MadridAges 35–80 - NCT06507228Recruiting
Simplified sleep apnea testing study
This trial is testing a new, automated way to diagnose obstructive sleep apnea (a condition where breathing stops and starts during sleep). If you have been referred from your primary care doctor for sleep apnea testing, you may be able to join.
LondonAges 18 years+ - NCT07305168Recruiting
Breathing after tonsil surgery in children with sleep apnea
This study looks at breathing problems that can happen after tonsil or adenoid surgery in children who have sleep apnea. Researchers want to learn more so they can make surgery safer for kids.
Edegem, AntwerpAges 1–18 - NCT07446634Recruiting
Jaw advancement surgery for sleep apnea
This study tests jaw advancement surgery for people with obstructive sleep apnea who haven't been helped by CPAP or mouthpieces. It looks at whether moving the jaw forward can improve breathing during sleep.
Falun, Dalarna CountyAges 18–70 - NCT04444778Enrolling by invitation

This study looks at how repeated episodes of low oxygen during sleep affect the body in people with severe sleep apnea. It may help researchers understand what causes symptoms and long-term risks, which could guide better treatment decisions.
Palma, Balearic IslandsAges 18–65 - NCT04092660Recruiting
Mouth guard study to reduce airway collapse in sleep apnea
This study tests whether using an anti-snoring mouth guard (a mandibular advancement appliance) can help keep your airway open during sleep if you have obstructive sleep apnea. If you’re referred for this kind of mouth guard, the trial will see if using it more regularly or in a specific way improves symptoms or breathing during sleep.
LondonAges 40–90 - NCT06390345Recruiting
Telehealth lifestyle and exercise for COPD and sleep apnea
This study tests a telehealth program that combines lifestyle coaching and exercise to help people with both COPD and sleep apnea improve their breathing and daily function. It may be a good fit if you are overweight, have a history of smoking, and feel short of breath during light activity.
Boise, IdahoAges 18 years+ - NCT06453018Recruiting
Sleep position therapy for children with sleep apnea
This trial tests if changing sleep position (like avoiding sleeping on the back) can improve sleep apnea in children aged 6 to 17. It may be an option if your child has moderate to severe sleep apnea that gets worse when lying on their back.
Hong KongAges 6–17 - NCT06608888Recruiting
Brain chemical study for sleep apnea and snoring
This study looks at how a brain chemical called 5-HT7 affects sleep apnea by testing different groups: people with sleep apnea, people who snore, and healthy volunteers. It aims to find new ways to help regulate breathing during sleep.
Beijing, Beijing MunicipalityAges 20–60 - NCT06634264Recruiting
Comparing two therapies for children with sleep apnea after surgery
This study compares two different exercises (called oral reeducation) to see which works better for children who still have breathing problems during sleep even after getting their tonsils or adenoids removed. It helps kids breathe easier at night.
Montreal, QuebecAges 4–14 - NCT06872242Recruiting
Italian study on obstructive sleep apnea types
This trial is studying different types of obstructive sleep apnea in Italian adults. It aims to understand more about the condition and may help find better treatments.
AcriAges 18 years+ - NCT07447011Recruiting
Glaucoma treatment response with sleep apnea lifestyle changes
This trial tests whether lifestyle changes can help open-angle glaucoma in people who also have obstructive sleep apnea and are obese. It may offer a non-drug way to manage both conditions.
Giza, DokkiAges 30–50 - 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 - 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 - 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 - NCT05918120Recruiting
Check portable sleep testing for sleep apnea in people with high blood pressure
This study tests whether using portable electronic recorders can help find sleep apnea (OSA) in people who have hypertension and are at higher risk. It may help doctors screen sooner and better understand sleep apnea in people with blood-pressure problems.
Toronto, OntarioAges 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 - 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+ - NCT06447818Recruiting
Airway changes after sleep apnea surgery
This study looks at how surgery for obstructive sleep apnea (a condition where breathing stops and starts during sleep) may affect your airway. The goal is to understand if the surgery makes it easier to manage your airway in the future.
Kocaeli, IzmıtAges 18–65 - 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.
