Recruiting studies
- NCT03621566Recruiting
Sleep apnea registry for adults with non-obstructive events
This study builds a registry to learn more about sleep apnea patterns, especially cases where most breathing events are not caused by blocked airway tissue. You may be able to join if you’re an adult with a specific sleep test result.
AalstAges 18 years+ - NCT06568159Recruiting
Sleep apnea treatment in heart patients
This study looks at how well people with heart disease or high heart risk follow their sleep apnea treatment, comparing a mouth device (MAD) to a CPAP machine. It aims to find which treatment works better for daily use.
MontpellierAges 18 years+ - NCT07364318Recruiting
Thinking and memory in sleep apnea
This study looks at how thinking and memory are affected in people with newly diagnosed obstructive sleep apnea (a condition where breathing stops briefly during sleep). It aims to understand the impact of sleep apnea on brain function.
BratislavaAges 18–65 - NCT06973928Recruiting
Does adenotonsillectomy improve mouth opening and quality of life?
This study looks at whether removing the tonsils and adenoids helps children with mild sleep apnea open their mouths wider and feel better overall.
Saint-Jean-de-VédasAges 3–7 - NCT06748703Recruiting
Optic nerve injury in obstructive sleep apnea patients
This study looks at whether sleep apnea affects the optic nerve, which connects your eye to your brain. It is for people newly diagnosed with sleep apnea who have not yet received treatment.
Nanjing, JiangsuAges 18–80 - NCT06783998Enrolling by invitation
Breathing muscle health in sleep apnea
This trial studies how sleep apnea affects the muscles you use to breathe. It may help doctors better understand and treat breathing problems in people with sleep apnea.
Mersin, MersinAges 18 years+ - NCT06382883Recruiting
Lifestyle and activity for sleep apnea
This study tests a lifestyle and physical activity program as a treatment for obstructive sleep apnea. It is for people who have not tried CPAP and want to see if exercise and healthy habits can help.
JyväskyläAges 18–70 - NCT06587256RecruitingPhase 2
Studying silicone mouth tape for snoring and mild sleep apnea
This trial tests if wearing silicone tape over your mouth at night can help reduce snoring and improve mild sleep apnea. You will use the tape and report how you and your partner feel about your snoring.
Baltimore, MarylandAges 18–75 - NCT06117579Recruiting
Breathing Muscle Training for Sleep Apnea
This trial tests whether a simple breathing exercise (training the muscles you use to breathe in) can improve sleep apnea symptoms in people who already use CPAP. The goal is to see if adding this training helps you feel better or need less CPAP pressure.
OrléansAges 18 years+ - NCT05953610RecruitingPhase 2
Surgery study for sleep apnea when CPAP won’t work
This Phase 2 trial tests whether a specific type of palate surgery can treat moderate-to-severe obstructive sleep apnea in people who cannot tolerate CPAP (a breathing mask). It also checks patient traits (based on sleep testing) to see who is most likely to benefit from surgery.
Santa Monica, CaliforniaAges 21 years+ - NCT05147649Recruiting
Brain scan study in severe sleep apnea without CPAP
This trial uses a specialized brain scan (MRI) to study people with severe obstructive sleep apnea who are not using CPAP. It also compares them with people who do not have sleep apnea to understand how brain function differs.
ReimsAges 18–75 - NCT05539716Recruiting
Treating sleep apnea to study effects on metabolism
This study tests a sleep apnea treatment approach and looks at how it may affect your body’s metabolism. You may be eligible if you’re an adult with sleep apnea and meet health and medication rules, and possibly if you already use a PAP machine regularly.
Miami, FloridaAges 18–70 - NCT05052216Recruiting
Wearable monitor study for kids’ sleep apnea
This study tests a wearable device that can help monitor breathing and sleep in children. It compares children with sleep apnea to children without sleep apnea using a simple nighttime monitoring approach.
Bethesda, MarylandAges 3–12 - NCT04186078Recruiting
Study symptoms and traits of sleep apnea in Korea
This study looks at people in Korea who may have sleep apnea based on common symptoms. The goal is to better understand who has sleep apnea and how it shows up, which may help improve future diagnosis and care.
SeoulAges 19 years+ - NCT02703220RecruitingPhase 4
Sleep apnea treatment in older adults
This study tests whether certain medications can help older adults with mild to moderate sleep apnea breathe better during sleep. It aims to improve sleep quality and safety for elderly patients.
Detroit, MichiganAges 60–89 - NCT07730879Recruiting
Wall Squat Exercise for Blood Pressure in Sleep Apnea
This study tests whether a simple wall squat exercise can help lower blood pressure in people who have both high blood pressure and sleep apnea (treated with CPAP). If you are using CPAP regularly and are otherwise healthy enough to exercise, this trial may be a good fit for you.
BragaAges 18–80 - NCT07301762Enrolling by invitation
Manual lymphatic drainage device for sleep apnea patients
This trial tests if a nightly automated manual lymphatic drainage device called Neuroglide can improve how the brain clears waste (glymphatic function) in people with obstructive sleep apnea. You may qualify if you are 50 or older, have sleep apnea, and regularly use CPAP.
Rochester, MinnesotaAges 50 years+ - NCT07082608Recruiting
Weight loss procedure plus lifestyle changes for sleep apnea
This study tests whether a stomach procedure called endoscopic sleeve gastroplasty (ESG) plus lifestyle changes helps people with sleep apnea lose more weight and improve their breathing compared to lifestyle changes alone. If you have moderate to severe sleep apnea and have struggled to lose weight, this may be an option.
Hyderabad, TelanganaAges 18 years+ - NCT06801366Recruiting
Video clips to help diagnose sleep apnea in children
This study tests if video clips recorded at home can help diagnose obstructive sleep apnea in children, possibly reducing the need for an overnight hospital sleep test. It may be a good fit if your child is between 2 and 18 years old, has been referred for a sleep study, and you have a smartphone or tablet.
Edmonton, AlbertaAges 2–18 - NCT06769607Recruiting
New auto-CPAP algorithm for sleep apnea
This study tests a new, smarter way for your CPAP machine to automatically adjust air pressure while you sleep. If you have a ResMed AirSense 10 or 11 and have been using it for a few months, you may be eligible.
Bella Vista, New South WalesAges 18 years+ - NCT06514482Recruiting
Spanish sleep apnea and daytime sleepiness registry
This study will collect information from people with suspected sleep apnea who feel very sleepy during the day. If you are 18 or older and about to have a sleep study, you may be able to help researchers learn more about this condition.
Logroño, La RiojaAges 18 years+ - NCT06471751Recruiting
Breathing and throat muscle exercises for moderate sleep apnea
This trial tests whether strengthening your breathing and throat muscles can improve moderate sleep apnea. It aims to see if these exercises help reduce breathing pauses and improve sleep quality.
GrenobleAges 18 years+ - NCT06043440RecruitingPhase 2
Oxygen therapy for sleep apnea in Down syndrome
This study tests whether oxygen therapy can help children with Down syndrome who have sleep apnea. It compares oxygen treatment to no treatment to see if it improves breathing during sleep and thinking skills.
Los Angeles, CaliforniaAges 5–18 - 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.

Common questions
- Are there clinical trials for sleep apnea?
- Yes. Clin2 currently lists 328 recruiting sleep apnea 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 sleep apnea 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 sleep apnea 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.
