Recruiting studies
- 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+ - NCT03948373Recruiting
Study of sleep apnea patients with normal blood pressure
This study is looking at a specific sleep-related condition (obstructive sleep apnea) in adults whose blood pressure is not high, and how their blood pressure rhythm changes over the day. If you have sleep apnea, participating could help researchers understand patterns that may affect long-term health.
LleidaAges 18–100 - 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+ - NCT04007380Recruiting
Sleep problems after spinal cord injury study
This study looks at how sleep-disordered breathing (breathing problems during sleep) affects mood, thinking, and behavior after a spinal cord injury. It may help researchers understand the impact of these sleep breathing issues and guide better support for people after injury.
Toronto, OntarioAges 18 years+ - NCT05089695Recruiting
Compare noninvasive breathing supports for breathing failure
This trial compares different ways to help you breathe without a breathing tube: helmet NIV, CPAP, or high-flow nasal oxygen. It aims to see which support works best for people who have sudden (acute) low oxygen levels.
RomeAges 18 years+ - NCT05262439Recruiting
Follow-up study of CPAP mask systems for sleep apnea
This study checks how ResMed CPAP mask systems work in real-life use for people with obstructive sleep apnea (OSA). It may help improve comfort, fit, and performance based on what patients experience over time.
Sydney, New South WalesAges 18–100 - NCT05473689Recruiting
Sleep study in early spinal cord injury
This study looks at how sleep quality affects movement problems after a new spinal cord injury. Researchers hope to identify sleep targets that could improve motor function during recovery.
Toronto, OntarioAges 18 years+ - NCT05846490RecruitingPhase 4
Sleep apnea treatment to improve blood pressure in kidney disease
This study tests whether treating obstructive sleep apnea can help control blood pressure in people with chronic kidney disease. If your sleep apnea is not currently being treated, participation may help your care team see whether safer breathing at night improves blood pressure control.
São PauloAges 18 years+ - NCT05939934Recruiting
Test a mouth device for sleep apnea after stopping CPAP
This study looks at whether a mandibular advancement device (a fitted mouthpiece) can control sleep apnea when you temporarily stop CPAP. It’s mainly for people who have been using CPAP for over a year but are now willing to try the mouth device.
AngersAges 18–75 - 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.
LleidaAges 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 - NCT06263608Recruiting
Sleep apnea testing and treatment for atrial fibrillation patients
This study tests a new way to check and treat sleep apnea in people with atrial fibrillation (AF). If you have AF and symptoms, you may be able to join and get sleep tracking and treatment that could help both your heart and sleep.
EdegemAges 18 years+ - NCT06264427Recruiting
Study of metabolism issues in Greenland
This study looks at the genes and physical traits of people in Greenland with type 2 diabetes or severe obesity. It aims to better understand these conditions to improve care.
Nuuk, SermersooqAges 18 years+ - NCT06319482Recruiting
Testing a new sleep apnea therapy device
This study tests a new proactive therapy for people recently diagnosed with moderate or severe sleep apnea. It aims to see how well patients stick with the treatment outside of a sleep lab.
Halifax, Nova ScotiaAges 18–70 - NCT06463561RecruitingPhase 4
CPAP for high cholesterol and sleep apnea
This study tests if CPAP therapy can improve cholesterol and uric acid levels in people with both high cholesterol and moderate to severe sleep apnea. It may help if you have sleep apnea and are looking for additional ways to manage your lipid levels.
Coslada, MadridAges 35–80 - NCT06554496Recruiting
Xanthine Oxidoreductase Levels in New Sleep Apnea Patients
This study measures a substance called XOR in the blood of people who have just been diagnosed with obstructive sleep apnea but haven't started treatment yet. It aims to see if XOR levels are linked to sleep apnea.
Nanjing, JiangsuAges 18–80 - NCT06611527Recruiting
Breathing therapy to improve lung function after heart surgery
This study tests a breathing treatment using mild air pressure after heart surgery to help your lungs work better and reduce complications. It may be an option for people at higher risk for lung problems or those with early breathing issues after surgery.
São Paulo, São PauloAges 18 years+ - NCT06668597Recruiting
Sleep apnea education and motivation program
This trial tests an educational program to help people with sleep apnea start using CPAP at home. The program is designed to motivate and guide you through the process of adapting to CPAP therapy.
Milan, MilanAges 18 years+ - NCT06694311Recruiting
Testing CPAP and high-flow oxygen for ARDS
This study tests two types of breathing support—CPAP (a mask that pushes air into your lungs) and high-flow nasal oxygen (a special tube in your nose)—to see which works better for people with ARDS, a serious lung condition. It may help you breathe more easily without needing a breathing tube.
Barcelona, BarcelonaAges 18–80 - 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 - NCT06795971Recruiting
Comparing oxygen methods for hypoxemic respiratory failure
This trial compares three ways of giving extra oxygen to people with low blood oxygen levels: a face mask with continuous pressure, a noninvasive ventilator, or high-flow oxygen through the nose. The goal is to see which method helps people avoid needing a breathing tube.
Nanjing, JiangsuAges 18 years+ - NCT06848647Recruiting
Treating sleep apnea to improve metabolism
This study tests whether treating sleep apnea with CPAP improves your body's metabolism (how your body uses energy). It's for people who have sleep apnea and are about to start CPAP therapy.
Uppsala, Uppsala CountyAges 18 years+ - NCT06915831Recruiting
Type 1 diabetes and sleep apnea study
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.

Common questions
- Are there clinical trials for cpap?
- Yes. Clin2 currently lists 82 recruiting cpap 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 cpap 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 cpap 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.
