Recruiting studies
- NCT05953610RecruitingPhase 2
Surgery study for sleep apnea when CPAP won’t work

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 - NCT06103630Recruiting
Mouth exercises for sleep apnea with mouthguard therapy
This study tests whether specific mouth and throat exercises can help people with sleep apnea who already use a mandibular advancement device (a type of mouthguard). The goal is to see if adding exercises improves sleep and breathing.
TainanAges 20 years+ - 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+ - NCT06150352Recruiting
Sleep apnea and memory in older adults with mild concerns
This trial looks at how sleep apnea affects memory and brain health in people who have mild memory problems or are worried about their memory. You will have a sleep study and brain scans to see if treating sleep apnea could help protect your thinking skills.
Hong KongAges 50–80 - 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 - NCT06258837Recruiting
Personalized surgery for sleep apnea in children with small tonsils
This study tests a personalized surgical approach for children with moderate to severe obstructive sleep apnea who have small tonsils. The goal is to see if tailored surgery improves their breathing during sleep and overall health.
Ann Arbor, MichiganAges 2–17 - 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+ - 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 - NCT06317701Recruiting
Nerve stimulation for sleep apnea in overweight adults
This trial tests a nerve stimulation treatment for obstructive sleep apnea in people who are overweight and cannot tolerate CPAP. It focuses on how the treatment affects metabolism and weight.
Chicago, IllinoisAges 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 - NCT06331819Recruiting
Sleep apnea, facial pigmentation, and fainting study
This study looks at whether sleep apnea, facial pigmentation, and fainting symptoms are connected. It aims to help understand these conditions better.
AmmanAges 18 years+ - NCT06367400Recruiting
Validating a Sleep Questionnaire for Swedish Children
This study tests a sleep questionnaire designed to help diagnose sleep-related breathing problems in children. It aims to see if the questionnaire works well for Swedish children, making it easier for doctors to spot these issues early.
UppsalaAges 1.5 years–15 years - NCT06374147Recruiting
Vibrating pad for apnea in very premature babies
This trial is testing a special vibrating pad (Prapela®) placed in the incubator to see if it can help reduce apnea episodes (pauses in breathing) in very premature babies. It is for babies who are already getting caffeine medicine and need only minimal extra breathing support.
Birmingham, AlabamaAges birth–3 months - NCT06382883Recruiting
Lifestyle and activity for sleep apnea
This study tests a lifestyle and physical activity program as a treatment for obstructive sleep apnea. It is for people who have not tried CPAP and want to see if exercise and healthy habits can help.
JyväskyläAges 18–70 - NCT06397365Recruiting
Hypnosis for better CPAP use
This trial tests if hypnosis sessions can help people with sleep-disordered breathing use their CPAP machine more consistently, especially if they are currently using it less than 3 hours a night.
Lausanne, Canton of VaudAges 18 years+ - 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 - NCT06463561RecruitingPhase 4

Common questions
- Are there clinical trials for apnea?
- Yes. Clin2 currently lists 367 recruiting 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 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 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.
