Recruiting studies
- NCT06748703Recruiting
Optic nerve injury in obstructive sleep apnea patients
This study looks at whether sleep apnea affects the optic nerve, which connects your eye to your brain. It is for people newly diagnosed with sleep apnea who have not yet received treatment.
Nanjing, JiangsuAges 18–80 - NCT07364318Recruiting
Thinking and memory in sleep apnea
This study looks at how thinking and memory are affected in people with newly diagnosed obstructive sleep apnea (a condition where breathing stops briefly during sleep). It aims to understand the impact of sleep apnea on brain function.

Comparing CPAP pressure formulas vs lab titration for sleep apnea
This study compares two ways to set CPAP machine pressure for Thai people with obstructive sleep apnea: using a quick formula versus a full overnight lab test. It helps find the best pressure more easily.
Pathum ThaniAges 18 years+ - NCT02410850Recruiting
Test how well long-term mouth devices work for sleep apnea
This trial looks at how effective an oral (mouth) appliance is over the long term for people with obstructive sleep apnea. If you already use a mouth device, this study may help doctors understand whether it continues to work well over time.
Vancouver, British ColumbiaAges 18–90 - 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+ - 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+ - NCT06522815Recruiting
Updating AI for sleep apnea monitoring
This study tests an updated computer program (AI) that uses a wearable device to monitor sleep apnea. If you are 19 or older and already scheduled for a sleep study, you may be able to help improve how this technology detects breathing pauses during sleep.
SeoulAges 19 years+ - NCT07191314Recruiting
Long-term study of a nasal airway for sleep apnea
This study is for people who already finished a previous study using a device called a nasopharyngeal airway (a small tube placed in the nose to help with breathing during sleep). It will check how well the device works over a longer time.
Ann Arbor, MichiganAges 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 - NCT06471751Recruiting
Muscle training for moderate sleep apnea
This trial tests whether a 3-month program of muscle exercises for breathing and mouth strengthens the airway, to help people with moderate sleep apnea breathe better during sleep and possibly reduce their symptoms.
GrenobleAges 18 years+ - NCT06769607Recruiting
New auto-CPAP algorithm for sleep apnea
This study tests a new, smarter way for your CPAP machine to automatically adjust air pressure while you sleep. If you have a ResMed AirSense 10 or 11 and have been using it for a few months, you may be eligible.
Bella Vista, New South WalesAges 18 years+ - NCT06801366Recruiting
Video clips to help diagnose sleep apnea in children
This study tests if video clips recorded at home can help diagnose obstructive sleep apnea in children, possibly reducing the need for an overnight hospital sleep test. It may be a good fit if your child is between 2 and 18 years old, has been referred for a sleep study, and you have a smartphone or tablet.
Edmonton, AlbertaAges 2–18 - NCT07301762Enrolling by invitation
Manual lymphatic drainage device for sleep apnea patients
This trial tests if a nightly automated manual lymphatic drainage device called Neuroglide can improve how the brain clears waste (glymphatic function) in people with obstructive sleep apnea. You may qualify if you are 50 or older, have sleep apnea, and regularly use CPAP.
Rochester, MinnesotaAges 50 years+ - NCT06586268Recruiting
Sleep changes after surgery in people with sleep apnea
This study looks at how sleep patterns change in the first three nights after surgery for people who have obstructive sleep apnea (OSA). It aims to understand how anesthesia and sleep apnea severity affect sleep quality during recovery.
Amsterdam, North HollandAges 18 years+ - NCT03860233RecruitingPhase 1
Oxytocin added to CPAP for obstructive sleep apnea
This early study tests whether adding oxytocin to your usual CPAP treatment improves obstructive sleep apnea. It may help see if oxytocin changes how well CPAP works or how people feel while using it.
Washington D.C., District of ColumbiaAges 18 years+ - 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 - 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 - 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 - NCT04399200Recruiting
Study apnea after stroke to prevent new heart events
This trial looks at sleep apnea (breathing pauses during sleep) in people soon after a first stroke or a TIA, to see if it can be linked to new cardiovascular (heart/blood vessel) events. It also aims to make sure you can safely follow the study and rehabilitation plan.
GrenobleAges 18–85 - NCT07555119Recruiting
Home Sleep Testing: Night-to-Night Measurement Variability Study
This study measures how sleep breathing patterns vary from night to night using home sleep testing. It helps researchers understand if portable sleep tests give consistent and reliable results.
BernAges 18 years+ - 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 - NCT03924817Recruiting
Registry study of mouth guards for sleep apnea
This registry study collects real-world information from adults who have been prescribed a mandibular advancement device (a custom mouth guard worn during sleep). It aims to understand how people use these devices and whether they help with obstructive sleep apnea symptoms.
Blaubeuren Abbey, Badden-WürttembergAges 18–99 - NCT04124848Recruiting
Sleep apnea study for Somali community adults
This study looks at obstructive sleep apnea—breathing pauses or poor breathing during sleep—in Somali community members. It aims to learn more about sleep apnea in this specific group, which can help guide better care.
Rochester, MinnesotaAges 18 years+ - NCT04659291Recruiting
Studying people in Hong Kong who may have sleep apnea
This study looks at people who may have obstructive sleep apnea, a breathing problem during sleep. It aims to better understand the condition in Hong Kong and what to do next for diagnosis or care.

Common questions
- Are there clinical trials for apnea, obstructive?
- Yes. Clin2 currently lists 302 recruiting apnea, obstructive 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 apnea, obstructive 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 apnea, obstructive 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.
