Recruiting studies
- NCT04903951RecruitingPhase 2
Check if early breathing support after stroke helps sleep apnea
This trial tests whether starting a breathing-support treatment soon after a first stroke improves outcomes in people who also have sleep apnea. It may help reduce complications and support recovery if you meet the specific timing and health criteria.
Matosinhos MunicipalityAges 18–80 - NCT04991389RecruitingPhase 4
Test a breathing study plan for kids with sleep apnea after surgery
This trial studies how to improve outcomes for children who still have obstructive sleep apnea after having their tonsils and adenoids removed. It uses computer modeling (based on breathing/airflow) and may include a special breathing gas during testing in some parts of the study.
Cincinnati, OhioAges 3–18 - NCT05237505RecruitingPhase 2
Sleep apnea plus COPD study to check heart and breathing effects
This Phase 2 study looks at the cardiovascular (heart/blood vessel) effects of having both sleep apnea and COPD. It may help doctors better understand who is at risk and how to manage these breathing problems together.
La Jolla, CaliforniaAges 40–79 - 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+ - NCT06512779Recruiting
Sleep apnea treatment clustering study
This study looks at sleep recordings to group people with obstructive sleep apnea based on their unique signals. The goal is to match each person to the best treatment for them.
TainanAges 20 years+ - 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 - 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 - NCT07464262Recruiting
Telemonitoring with CPAP for severe sleep apnea patients
This trial tests whether telemonitoring (checking in remotely) helps people with severe sleep apnea adjust to CPAP therapy. If you live in São Paulo and recently started CPAP, this study may help you get extra support.
São Paulo, São PauloAges 18–75 - NCT07603583Recruiting
Heart Rate Variability to Detect Sleep Apnea in Hypertension
This study tests whether a simple heart-rate measurement can help detect obstructive sleep apnea (a breathing condition during sleep) in people with high blood pressure. The goal is to find an easier way to screen for sleep apnea, which often goes undiagnosed but can worsen heart health.
Kaohsiung City, KaohsiungAges 18–65 - NCT03062748Enrolling by invitation
Study tests how sleep apnea and inflammation relate to risk
This study looks at people with mild to moderate obstructive sleep apnea (OSA) to understand how inflammation and breathing disruption may affect future heart and metabolism risk. It may help explain why some people develop higher risk even with milder sleep apnea.
Hershey, PennsylvaniaAges 18 years+ - NCT07447999Recruiting
Using AI to predict sleep apnea severity
This trial tests whether a special computer model can predict sleep apnea severity using a stethoscope and a fingertip oxygen sensor, instead of a full sleep test. It might help people get faster and easier sleep apnea diagnosis.
New Taipei CityAges 30–75 - NCT06336525Enrolling by invitation
Sleep health in rural Appalachia and Mississippi Delta
This study examines how sleep is linked to heart and metabolic health in people living in rural Appalachia and the Mississippi Delta. If you are already part of the RURAL Study, you may be able to join this sleep-focused part of the research.
Boston, MassachusettsAges 25–65 - NCT05197738Recruiting
Study using a sleep health app to improve sleep
This study tests a “sleep health” app (REFRESH) to see how it may help people track and improve sleep. You may be eligible if you’re an adult in the U.S. who can use the app on your own phone.
La Jolla, CaliforniaAges 18 years+ - NCT05890911Enrolling by invitation
Studying dopamine pathways in breathing problems during sleep
This study looks at how dopamine-related brain pathways may be involved in sleep-related breathing problems. It may help researchers better understand what causes these conditions and how to evaluate them with sleep testing.
WroclawAges 18–80 - NCT07086742Recruiting
Testing a smart mask that measures oxygen and pulse
This study tests a new 'smart mask' that can measure your oxygen levels and pulse rate. It is for healthy adults to see how well the mask works compared to standard devices.
GenkAges 18–65 - NCT06331819Recruiting
Sleep apnea, facial pigmentation, and fainting study
This study looks at whether sleep apnea, facial pigmentation, and fainting symptoms are connected. It aims to help understand these conditions better.
AmmanAges 18 years+ - NCT07195253Recruiting
Down syndrome and sleep apnea study in infants
This study looks at mouth and face features and sleep apnea in 6-month-old infants with Down syndrome. It may help doctors understand and treat sleep problems better.
BronAges 5 months–6 months - NCT06576310Recruiting
Predicting teeth changes from sleep apnea mouthpiece treatment
This study looks at people with sleep apnea who are using a special mouthpiece (mandibular advancement device). It aims to find out which factors predict changes in how your teeth fit together after using the device.
ToulouseAges 18 years+ - NCT04603196Recruiting
Study sleep apnea in adults with multiple sclerosis
This study looks at how often sleep apnea happens in people who have multiple sclerosis, and how it affects daily life and health. You may be invited to participate if you’re an adult with a confirmed multiple sclerosis diagnosis and can consent to the study.
Boston, MassachusettsAges 18 years+ - 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 - NCT06317701Recruiting
Nerve stimulation for sleep apnea in overweight adults
This trial tests a nerve stimulation treatment for obstructive sleep apnea in people who are overweight and cannot tolerate CPAP. It focuses on how the treatment affects metabolism and weight.
Chicago, IllinoisAges 18 years+ - NCT06698809Recruiting
Treating leftover sleepiness in sleep apnea patients
This study tests if a light therapy device can help reduce daytime sleepiness in people who are already using a CPAP machine for sleep apnea but still feel tired. It involves MRI scans and regular check-ins over two years.
New York, New YorkAges 18–75 - NCT06834724Recruiting
CPAP for sleep apnea and chronic pain
This study looks at whether CPAP treatment improves pain and daily life in people who have both sleep apnea and chronic pain. It tests if starting CPAP for the first time can help these symptoms.

Common questions
- Are there clinical trials for sleep apnea?
- Yes. Clin2 currently lists 344 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.
