Drug to activate a sleep-control pathway for sleep apnea
This early study tests a medicine that is meant to improve how your brain and breathing muscles work during sleep for obstructive sleep apnea (OSA). If you qualify, you would be monitored during sleep to see whether the treatment changes breathing events and oxygen levels.
Boston, MassachusettsAges 18–70 - NCT05735444Recruiting
CPAP registry for sleep apnea in people with high blood pressure
This study keeps a record of people with obstructive sleep apnea (OSA) who also have high blood pressure, to better understand how CPAP is used and what outcomes happen. It may help your care team by contributing your information to a large multi-center study in China.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06047496RecruitingEarly Phase 1
Time-restricted eating for sleep apnea
This study tests whether limiting your eating to a shorter daily window can improve health in people with untreated moderate to severe sleep apnea. You would eat all your meals within a set number of hours each day while tracking your progress on your smartphone.

Perimenopausal symptom study for women with sleep apnea
This study tests whether treating sleep apnea can help women with menopause-related symptoms. It uses a home sleep test to check for sleep apnea and may offer treatment options to improve sleep and quality of life.
Chicago, IllinoisAges 18–40 - NCT06283095Recruiting
Expanding the palate to help sleep apnea
This surgery expands the palate to treat obstructive sleep apnea caused by a narrow upper airway. It may help people with mild to moderate sleep apnea who have a specific type of airway collapse seen on a sleep-endoscopy test.
AsyutAges 18–70 - NCT06103630Recruiting
Mouth exercises for sleep apnea with mouthguard therapy
This study tests whether specific mouth and throat exercises can help people with sleep apnea who already use a mandibular advancement device (a type of mouthguard). The goal is to see if adding exercises improves sleep and breathing.
TainanAges 20 years+ - NCT04005508Recruiting
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 - NCT07826429Recruiting
Testing a new breathing mask for sleep apnea
This study tests a new style of breathing mask (called the F&P Licorice Mask) for people who already use CPAP or similar therapy for sleep apnea. You'll use the mask at home and give feedback on how it feels and works, which could help make future masks more comfortable.
St Louis, MissouriAges 22 years+ - 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+ - NCT06115018Recruiting
Oral device for sleep apnea after palate surgery
This study tests whether a special oral device (OPR) can help people with sleep apnea after they have had palate surgery. It looks at how well it works and if the benefits last over time.
TainanAges 18–100 - NCT07743931Recruiting
Combining CPAP and a sleep medication for sleep apnea with insomnia
This study tests combining a CPAP machine with a sleep medication called daridorexant to treat people who have both sleep apnea and insomnia. It aims to see if this combination therapy is safe and effective for people who are just starting treatment.
GrenobleAges 18–75 - 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 - NCT07736872Recruiting
Sleep apnea screening in diverse groups
This study is screening people from different backgrounds for obstructive sleep apnea (a condition where breathing stops and starts during sleep). It uses a sleep test and questionnaires to see if you might have it.
Guangzhou, GuangdongAges 18–80 - NCT07740213Enrolling by invitation
Sleep apnea study at Sohag University hospitals

Sohag, Sohag GovernorateAges 18 years+ - NCT06319482Recruiting
Testing a new sleep apnea therapy device
This study tests a new proactive therapy for people recently diagnosed with moderate or severe sleep apnea. It aims to see how well patients stick with the treatment outside of a sleep lab.

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 - NCT07724938Recruiting

Common questions
- Are there clinical trials for obstructive sleep apnea (osas)?
- Yes. Clin2 currently lists 229 recruiting obstructive sleep apnea (osas) 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 (osas) 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 (osas) 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.
