Detroit, MichiganAges 60 years+ - NCT04186078Recruiting
Study symptoms and traits of sleep apnea in Korea
This study looks at people in Korea who may have sleep apnea based on common symptoms. The goal is to better understand who has sleep apnea and how it shows up, which may help improve future diagnosis and care.
SeoulAges 19 years+ - 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 - NCT04572503Recruiting
Surgery for mild to moderate sleep apnea not helped by CPAP
This trial looks at a modified palate surgery to treat mild to moderate obstructive sleep apnea in people whose CPAP machine isn’t working for them. It may help if your sleep apnea is caused by the tissue behind the soft palate collapsing rather than other airway areas.
Banhā, Qalyubia GovernorateAges 18 years+ - NCT04943562Recruiting
Testing sleep sensors to score your sleep stages
This study checks whether wearable sensors (like a sleep band and a wearable EEG) and a phone can accurately identify your sleep stages. It includes healthy people and people with sleep problems to see how well the devices work and whether results match a standard sleep lab test.
São Caetano do Sul, São PauloAges 20–80 - NCT05147649Recruiting
Brain scan study in severe sleep apnea without CPAP
This trial uses a specialized brain scan (MRI) to study people with severe obstructive sleep apnea who are not using CPAP. It also compares them with people who do not have sleep apnea to understand how brain function differs.
ReimsAges 18–75 - NCT05237505RecruitingPhase 2
Sleep apnea plus COPD study to check heart and breathing effects
This Phase 2 study looks at the cardiovascular (heart/blood vessel) effects of having both sleep apnea and COPD. It may help doctors better understand who is at risk and how to manage these breathing problems together.
La Jolla, CaliforniaAges 40–79 - NCT05382754Recruiting
Home sleep testing for children being checked for sleep apnea
This trial tests whether home sleep testing can help diagnose sleep apnea in children. It is for kids who are already being referred for an in-lab sleep study at CHOP.
Philadelphia, PennsylvaniaAges 5–12 - NCT05497180RecruitingPhase 1
Testing an oral device to reduce snoring and mild sleep apnea
This Phase 1 study tests whether a passive mouth/oral appliance can lessen snoring and mild obstructive sleep apnea. It may help you by improving airflow during sleep without other intensive treatments.
Edmonton, AlbertaAges 18 years+ - NCT05508971Recruiting
Personalized tonsil surgery for sleep apnea in children with Down syndrome
This study tests whether a personalized surgical approach can treat moderate to severe obstructive sleep apnea (OSA) in children with Down syndrome. The goal is to improve breathing during sleep and overall sleep health.
Aurora, ColoradoAges 2–17 - NCT05575401Recruiting
Track surgery results in kids getting tonsil removal
This trial looks at how well a specific throat surgery technique works in children who are having their tonsils removed (with or without removing adenoids). It may help improve how doctors choose and perform surgery for safer, better recovery.
Murrieta, CaliforniaAges 3–17 - NCT05735444Recruiting
CPAP registry for sleep apnea in people with high blood pressure
This study keeps a record of people with obstructive sleep apnea (OSA) who also have high blood pressure, to better understand how CPAP is used and what outcomes happen. It may help your care team by contributing your information to a large multi-center study in China.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05911646Recruiting
Tool to help decisions for mild sleep apnea in kids
This trial looks at OSA-18, a questionnaire that may help families and clinicians make better decisions about treatment for a child’s mild sleep apnea. It specifically focuses on children with enlarged tonsils and mild sleep study results.
Hartford, ConnecticutAges 3–12 - NCT06030349Recruiting
Breathing support for kids with Down syndrome and sleep apnea
This trial looks at how well non-invasive breathing machines help children with Down syndrome who have obstructive sleep apnea. It tracks their health and sleep over time to see if the treatment works and improves daily life.
DublinAges 6 months–16 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 - NCT06061562Recruiting
Sleep Apnea and Activity in Down Syndrome
This trial looks at whether physical activity can help improve sleep apnea in people with Down syndrome. It aims to find better ways to manage breathing problems during sleep.
La TroncheAges 6 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 - NCT06117579Recruiting
