Recruiting studies
- NCT05678088Recruiting
Exercises for sleep apnea when CPAP and other options don’t work
This trial tests whether doing exercises for the throat and mouth can reduce obstructive sleep apnea symptoms in people who cannot tolerate CPAP and aren’t using other device or surgery treatments. It may help if your apnea is mainly caused by blocked airflow rather than problems with breathing control.
Toronto, OntarioAges 18 years+ - NCT05804084RecruitingPhase 2
Acetazolamide for sleep apnea: sleep and brain outcomes
This study tests acetazolamide (a medicine that changes breathing chemistry) to see how it affects sleep quality and neurocognitive (brain/memory/attention) outcomes in adults with untreated moderate to severe sleep apnea. You may be eligible if you have significant sleep apnea but do not have certain safety risks or need to start standard sleep apnea treatment right away.
La Jolla, CaliforniaAges 18 years+ - NCT06167369Recruiting
Sleep apnea, brain health, and CPAP therapy study
This study looks at how sleep apnea affects your brain and thinking skills. Researchers want to see if CPAP treatment can help protect your brain health.
Dresden, SaxonyAges 18 years+ - NCT06189755Recruiting
MicroRNA markers for sleep apnea
This trial is studying tiny molecules in the blood (called microRNAs) to see if they can help diagnose or monitor obstructive sleep apnea. It compares people with moderate to severe sleep apnea who are starting PAP therapy with people who do not have sleep apnea.
Columbus, OhioAges 18–75 - 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 - NCT06519149Recruiting
Device for sleep apnea without CPAP
This trial tests a device placed in your mouth during sleep to treat obstructive sleep apnea. It may be an option if you cannot or do not want to use a CPAP machine.
Austin, TexasAges 18 years+ - NCT06664450Recruiting
Brain fog in sleep apnea
This study looks at brain fog (difficulty thinking or concentrating) in people with severe sleep apnea, both before and after starting CPAP therapy. It aims to understand how sleep apnea treatment affects brain function.
Milan, MIAges 18 years+ - NCT06681974RecruitingPhase 3
Throat therapy for sleep apnea without CPAP
This trial tests a type of mouth and throat therapy to see if it can help people with mild to moderate sleep apnea who can't or don't want to use a CPAP machine. It might be an option if you want a non-machine treatment for your sleep apnea.
SantanderAges 18–70 - NCT06715228Recruiting
Breathing exercise for sleep apnea
This trial tests a special breathing exercise program (called Shitali) to see if it helps people with mild or moderate sleep apnea who are not obese. If you qualify, you'll learn a gentle therapy that may improve your sleep without machines or medicine.
Dokki, Giza GovernorateAges 35–55 - NCT06720545Recruiting
Short break from nerve stimulation therapy and heart health
This study looks at what happens to your heart health and metabolism when you stop using a nerve stimulator for sleep apnea for a short time. It may help understand the risks and benefits of taking a break from this therapy.
New York, New YorkAges 18 years+ - NCT06808464Recruiting
Heart rate changes during sleep in severe sleep apnea
This study looks at how your heart rate changes during sleep in people with severe sleep apnea compared to healthy people. It uses a simple overnight recording to measure your nervous system activity.
LilleAges 18–64 - NCT06862297Recruiting
Comparing a new jaw tracking device to standard sleep study for sleep apnea
This study compares a new device that tracks jaw movement during sleep to the standard sleep study (polysomnography) for diagnosing sleep apnea. You may be eligible if you have symptoms like loud snoring or daytime sleepiness and have been referred for a sleep study.
TaipeiAges 20–75 - NCT06872242Recruiting
Italian study on obstructive sleep apnea types
This trial is studying different types of obstructive sleep apnea in Italian adults. It aims to understand more about the condition and may help find better treatments.
AcriAges 18 years+ - NCT06930404Recruiting
New ways to diagnose sleep apnea
This study tests new ways to diagnose obstructive sleep apnea. If you haven't been diagnosed with sleep apnea and are generally healthy, you may be able to join.
Sydney, New South WalesAges 18 years+ - NCT06960200RecruitingPhase 2
Phototherapy for sleep apnea when a mouthpiece didn't work
This study tests a light-based treatment (phototherapy) for people with sleep apnea who tried an oral mouthpiece but still have symptoms. The goal is to see if this therapy can offer relief when other options haven't worked fully.
EdmontonAges 18 years+ - NCT06971796Recruiting
EURO-STIM Registry for Inspire implant users
This study gathers information from people who have or will receive an Inspire implant for sleep apnea. By joining, you help doctors learn how well the therapy works over time.
KlagenfurtAges 18 years+ - NCT07129967Recruiting
Mouth and face exercises for childhood sleep apnea
This study tests whether simple exercises for the mouth, tongue, and face can help children with mild sleep apnea breathe better during sleep. It's a non-surgical, drug-free approach that may be a good option for kids who haven't tried other treatments.
GhentAges 6–12 - NCT07277608Recruiting
Study on sleep apnea patients and their health over time
This study looks at patients with suspected or confirmed obstructive sleep apnea (a condition where breathing stops and starts during sleep) to understand the condition better. Researchers will follow patients for at least one year to learn more about the underlying causes and how it affects health.
Beijing, Beijing MunicipalityAges Any age - NCT07301710RecruitingPhase 1/Phase 2
Low-tech treatments for sleep apnea
This study tests simple, low-tech treatments (like exercises) for sleep apnea. It's for people who are newly diagnosed or whose current treatment isn't working, and who are willing to pause their usual treatment for 3 months.
Bethesda, MarylandAges 18–65 - NCT07303452Recruiting
New device for sleep apnea in adults
This trial tests a new device called Restera™ Serene™ for people with obstructive sleep apnea who cannot use or do not want a CPAP mask. It may offer an alternative treatment option.
PerthAges 18 years+ - NCT03307330Recruiting
Study of body fat in people with obstructive sleep apnea
This study looks at how body fat (“adipose tissue”) may differ in people with obstructive sleep apnea. You may be asked for consent and could be asked to stop certain medicines short-term so researchers can take a safe fat sample.
Rochester, MinnesotaAges 18–60 - NCT07427589Recruiting
New Heart Tests in Sleep Apnea
This study looks at how sleep apnea affects your heart and blood vessels over time. It uses a sleep study and heart tests to see if certain measurements can predict heart health changes.
AntwerpAges 18 years+ - NCT07476313Enrolling by invitation
Testing a new home sleep system for moderate to severe sleep apnea
This study tests a home sleep testing system called SleepView+ in people who have already been scheduled for an overnight sleep lab study. If you have moderate to severe obstructive sleep apnea, this device might offer a more convenient way to monitor your sleep at home.

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.
