Recruiting studies
- NCT06782737Enrolling by invitation
Mediterranean diet vs standard diet for sleep apnea
This study compares the Mediterranean diet to a standard diet to see which one improves heart and metabolic health in people with moderate to severe sleep apnea. You might benefit from learning if changing what you eat can help manage your condition.
Mexico City, Mexico CityAges 30–70 - NCT06614582Enrolling by invitation
Long-term nose tube study for children with weak muscle tone
This study looks at the long-term safety and effectiveness of a nose tube (nasopharyngeal airway) for children who have obstructive sleep apnea due to weak muscle tone. It's for children who already used this device in a previous study.
Ann Arbor, MichiganAges 3–23 - NCT06434558Enrolling by invitation
MRI predictors of cryolysis for sleep apnea
This study uses MRI scans to see how well a cold treatment (cryolysis) works for obstructive sleep apnea. It is only open to people already in the ARCTIC-3 trial at the University of Pennsylvania.
Philadelphia, PennsylvaniaAges Any age - NCT06330116Enrolling by invitation
Mouth and throat exercises for snoring and mild sleep apnea
This study tests different forms of oral myofunctional therapy (exercises for your mouth and throat) to find out which works best for reducing snoring and mild to moderate sleep apnea. It may help you breathe better and sleep more soundly.
Köge, Region SjællandAges 18–75 - NCT04905238Enrolling by invitation
Sleep apnea study linking breathing markers to memory changes
This trial looks at how severe sleep apnea breathing patterns relate to body “biomarkers” linked to Alzheimer’s disease, using blood or other measures. It may help researchers understand whether sleep apnea is connected to memory and brain health—and who might benefit most from better sleep care.
Palma, Balearic IslandsAges 18–65 - NCT04444778Enrolling by invitation
Study intermittent low oxygen in sleep apnea
This study looks at how repeated episodes of low oxygen during sleep affect the body in people with severe sleep apnea. It may help researchers understand what causes symptoms and long-term risks, which could guide better treatment decisions.
Palma, Balearic IslandsAges 18–65 - NCT03255408RecruitingPhase 1/Phase 2
Sleep study testing breathing and blood flow in healthy adults
This study looks at how your brain blood flow and breathing change during sleep under normal oxygen and reduced oxygen. It will only include healthy adults so researchers can learn what “intermittent hypoxia” does to the body in people without medical problems.
Calgary, AlbertaAges 18–45 - 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+ - NCT06564896Recruiting
Comparing sleep apnea treatments (CPAP vs alternatives)
This trial compares different positive airway pressure (PAP) machines to see which works best for people with moderate to severe sleep apnea. If you have been diagnosed but haven't used a CPAP yet, this study may help find the best option for you.
Cheras, Kuala LumpurAges 18 years+ - NCT05978505RecruitingPhase 2
Reboxetine for sleep apnea after ENT surgery
This study tests if the medication reboxetine helps reduce sleep apnea symptoms after planned upper airway surgery. It may be a good fit if you have sleep apnea and are having surgery on your nose or throat.
Bedford Park, South AustraliaAges 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 - NCT07259200Recruiting
Sleep quality after atrial fibrillation ablation
This study looks at how treating AFib with a procedure called catheter ablation might affect your sleep quality. You can join if you have AFib and are already planning to have this procedure, and you also have at least one risk factor for sleep apnea.
Grodzisk MazowieckiAges 18 years+ - NCT07332780Recruiting
Tonsil and adenoid surgery for kids with mild breathing troubles during sleep
This study looks at whether removing tonsils and adenoids can help improve spine curves in children who have mild sleep-disordered breathing. It may help prevent scoliosis from getting worse.
Wenzhou, ZhejiangAges 6–15 - NCT06380491RecruitingPhase 4
Melatonin for nighttime blood pressure in sleep apnea
This study tests whether melatonin can help lower nighttime blood pressure and improve sleep quality in people with obstructive sleep apnea who have 'non-dipping' blood pressure (blood pressure that stays high at night).
Mexico CityAges 18–60 - NCT07220525Recruiting
Sleep and heart rhythm study for people with sleep apnea device
This study looks at how turning off your sleep apnea device for short periods affects your heart rhythm, especially if you have a condition like atrial fibrillation. It may help understand the link between sleep and heart health.
San Francisco, CaliforniaAges 21 years+ - NCT02703220RecruitingPhase 4
Sleep apnea treatment in older adults
This study tests whether certain medications can help older adults with mild to moderate sleep apnea breathe better during sleep. It aims to improve sleep quality and safety for elderly patients.
Detroit, MichiganAges 60–89 - NCT03621566Recruiting
Sleep apnea registry for adults with non-obstructive events
This study builds a registry to learn more about sleep apnea patterns, especially cases where most breathing events are not caused by blocked airway tissue. You may be able to join if you’re an adult with a specific sleep test result.
AalstAges 18 years+ - NCT07493629Recruiting
Study on immune status and disease control in inflammatory airway diseases
This study looks at how the immune system works and how well diseases like asthma, COPD, and others are controlled. You may join if you have one of these conditions or if you are a healthy volunteer or smoker without lung disease.
Ningbo, ZhejiangAges 18 years+ - NCT06372847Recruiting
Sleep apnea nerve stimulation study
This trial tests a nerve-stimulation implant for sleep apnea when other treatments haven't worked. It may help if you have moderate to severe apnea, a BMI under 32, and have tried CPAP and a mouth device without success.
Edegem, AntwerpenAges 18 years+ - NCT06896448Recruiting
Sleep apnea screening for head and neck cancer patients
This study tests a smartphone app (Apneal) to screen for sleep apnea in people who are being checked for head and neck cancer. It aims to find sleep problems early so they can be treated.
Caen, FranceAges 18 years+ - NCT05612594RecruitingPhase 4
Study of an SGLT2 pill for sleep apnea in overweight adults
This study tests whether taking an SGLT2 inhibitor pill (bexagliflozin) can improve obstructive sleep apnea and related body measurements. It focuses on people who are overweight or obese and have confirmed obstructive sleep apnea.
New Haven, ConnecticutAges 18 years+ - NCT05986487Recruiting
Sleep apnea treatment for better blood pressure control
This trial tests whether treating sleep-disordered breathing (like sleep apnea) can help lower blood pressure in people with high blood pressure. You may join if you have high blood pressure and haven't been diagnosed with a sleep disorder before.

Common questions
- Are there clinical trials for obstructive sleep apnea?
- Yes. Clin2 currently lists 310 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.
