Sleep apnea treatment for AFib: a personalized trial
This study tests whether treating sleep apnea with a CPAP machine can reduce the number of AFib episodes you have. It's a personalized 'N-of-1' trial, meaning you'll try both CPAP and no CPAP at different times to see what works best for you.
Cleveland, OhioAges 18–85 - NCT07039500Recruiting
Severe sleep apnea's impact on hearing and thinking
This study looks at how severe sleep apnea affects your brain's ability to process sounds and think clearly. You will have hearing tests and an EEG, which is a safe brainwave recording, to see if treating sleep apnea can help your hearing and thinking.
Beijing, Beijing MunicipalityAges 20–60 - NCT06808464Recruiting

This study looks at how sleep apnea affects blood sugar control in adults with type 1 diabetes. It may help researchers understand if treating sleep apnea improves diabetes management.
Chicago, IllinoisAges 18–50 - 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+ - NCT06578390Recruiting
Testing a smartphone app for sleep apnea diagnosis
This trial tests whether a smartphone app (Apneal®) can accurately diagnose sleep apnea during a routine sleep study. If you are already going to have a sleep study, you may be able to help test this device.
Aix-en-ProvenceAges 18 years+ - 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+ - NCT06312956Recruiting
Sleep Apnea and Ventilotherapy: A Study Before and After Treatment
This trial studies how sleep apnea affects the body and brain before and after starting treatment with a breathing device (ventilotherapy). It aims to understand the benefits of early treatment for people with obstructive sleep apnea.
Piancavallo, VCOAges 20–60 - NCT06462287RecruitingPhase 2
Testing a substance P blocker for high blood pressure and sleep apnea
This study tests if a drug that blocks substance P can lower a hormone called aldosterone in people with both severe sleep apnea and high blood pressure. If you have these conditions, this trial may help find a new treatment option.
Rouen, FranceAges 18–75 - 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+ - NCT06089603RecruitingPhase 4
CPAP for Sleep Apnea with High Red Blood Cells
This study tests whether CPAP therapy (a machine that helps keep your airway open while you sleep) can lower high red blood cell counts in people who have both sleep apnea and polycythemia. It may help reduce the need for other treatments.
Madrid, MadridAges 18–80 - 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+ - 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 - NCT05911646Recruiting
Tool to help decisions for mild sleep apnea in kids
This trial looks at OSA-18, a questionnaire that may help families and clinicians make better decisions about treatment for a child’s mild sleep apnea. It specifically focuses on children with enlarged tonsils and mild sleep study results.
Hartford, ConnecticutAges 3–12 - NCT04943562Recruiting
Testing sleep sensors to score your sleep stages
This study checks whether wearable sensors (like a sleep band and a wearable EEG) and a phone can accurately identify your sleep stages. It includes healthy people and people with sleep problems to see how well the devices work and whether results match a standard sleep lab test.
São Caetano do Sul, São PauloAges 20–80 - 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 - 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 - NCT05508971Recruiting
Personalized tonsil surgery for sleep apnea in children with Down syndrome
This study tests whether a personalized surgical approach can treat moderate to severe obstructive sleep apnea (OSA) in children with Down syndrome. The goal is to improve breathing during sleep and overall sleep health.
Aurora, ColoradoAges 2–17 - NCT05497180RecruitingPhase 1
Testing an oral device to reduce snoring and mild sleep apnea
This Phase 1 study tests whether a passive mouth/oral appliance can lessen snoring and mild obstructive sleep apnea. It may help you by improving airflow during sleep without other intensive treatments.
Edmonton, AlbertaAges 18 years+ - NCT05382754Recruiting
Home sleep testing for children being checked for sleep apnea
This trial tests whether home sleep testing can help diagnose sleep apnea in children. It is for kids who are already being referred for an in-lab sleep study at CHOP.

Common questions
- Are there clinical trials for sleep apnea syndromes?
- Yes. Clin2 currently lists 118 recruiting sleep apnea syndromes 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 syndromes 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 syndromes 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.
