Study sleep apnea and heart outcomes in high-risk atrial fibrillation
This trial looks at how obstructive sleep apnea (OSA, a breathing problem during sleep) relates to heart outcomes in people with atrial fibrillation (AF). It may help doctors better predict risk and choose safer care for people who are high cardiovascular risk.
SingaporeAges 22–99 - NCT06464757Recruiting
Laryngomalacia and breathing in children: before and after treatment study
This trial is for children with laryngomalacia (a floppy voice box) who have noisy breathing and trouble breathing. It will check how they are doing before and after treatment, and follow up for one year to see how their quality of life improves.
OsloAges 1 week–12 months - NCT06463561RecruitingPhase 4
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 - 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+ - NCT07785999Recruiting
Wearable ring sensor for diagnosing sleep apnea in adults
This study tests whether a wearable ring sensor can help diagnose obstructive sleep apnea (a condition where breathing stops during sleep) compared to the standard in-lab sleep test. If you have suspected sleep apnea and are generally healthy, this study might help you get a simpler and more convenient diagnosis.
Pantai Valley, Kuala LumpurAges 18 years+ - NCT07789834Recruiting
Oral appliance therapy for sleep apnea study
This study looks at how well an oral appliance (a mouthguard) works for treating obstructive sleep apnea (OSA). It uses a questionnaire to track your progress and makes sure the treatment is helping you sleep better.
Henderson, NevadaAges 18 years+ - NCT07744854Recruiting
Monitoring breathing with sensors during sleep
This study tests two wearable sensors that track how hard you breathe while you sleep. It may help diagnose sleep and breathing problems without needing a hospital visit.
Taipei, TaiwanAges 18 years+ - NCT07743892Recruiting
Sleep apnea and body awareness study
This study looks at how people with obstructive sleep apnea (OSA) sense and understand their bodies, which may help improve treatment. If you have been diagnosed with OSA, you might be able to join.
KarabükAges 18–65 - 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 - NCT07740213Enrolling by invitation
Sleep apnea study at Sohag University hospitals

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 - NCT06634264Recruiting

Common questions
- Are there clinical trials for obstructive sleep apnea?
- Yes. Clin2 currently lists 301 recruiting obstructive 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 obstructive 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 obstructive 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.
