- NCT07434050RecruitingPhase 3
Study of XW003 for obesity with sleep apnea on CPAP therapy
This trial tests an investigational drug called XW003 to see if it helps people with obesity and obstructive sleep apnea who are already using a positive airway pressure (PAP) machine, like CPAP. It aims to improve weight loss and sleep apnea symptoms.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07444372Recruiting
CPAP for Sleep Apnea After Atrial Fibrillation Ablation
This trial tests whether starting CPAP therapy (a breathing mask used during sleep) after a heart procedure called atrial fibrillation ablation can help people with both sleep apnea and atrial fibrillation. It might lower the chance of the heart rhythm problem coming back.
Beijing, Beijing MunicipalityAges 18–75 - NCT07447011Recruiting
Glaucoma treatment response with sleep apnea lifestyle changes
This trial tests whether lifestyle changes can help open-angle glaucoma in people who also have obstructive sleep apnea and are obese. It may offer a non-drug way to manage both conditions.
Giza, DokkiAges 30–50 - 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 - NCT07464262Recruiting
Telemonitoring with CPAP for severe sleep apnea patients
This trial tests whether telemonitoring (checking in remotely) helps people with severe sleep apnea adjust to CPAP therapy. If you live in São Paulo and recently started CPAP, this study may help you get extra support.
São Paulo, São PauloAges 18–75 - NCT07427589Recruiting
New Heart Tests in Sleep Apnea
This study looks at how sleep apnea affects your heart and blood vessels over time. It uses a sleep study and heart tests to see if certain measurements can predict heart health changes.
AntwerpAges 18 years+ - NCT07530302Recruiting
Better ways to adjust CPAP therapy when it isn't working well
This trial tests whether a wearable device called Sunrise can help doctors adjust your CPAP machine better than standard sleep tests. If your current CPAP isn't stopping all your breathing pauses, this study may help find the right adjustments for you.
GrenobleAges 18–85 - NCT07601724Recruiting
How fluid buildup affects sleep apnea in heart failure
This study looks at how excess fluid in the body affects sleep apnea (pauses in breathing during sleep) in people hospitalized with heart failure. Researchers will measure sleep apnea before and after treatment to reduce the fluid, which may help doctors better manage both conditions together.
JerusalemAges 18 years+ - NCT07603583Recruiting
Heart Rate Variability to Detect Sleep Apnea in Hypertension
This study tests whether a simple heart-rate measurement can help detect obstructive sleep apnea (a breathing condition during sleep) in people with high blood pressure. The goal is to find an easier way to screen for sleep apnea, which often goes undiagnosed but can worsen heart health.
Kaohsiung City, KaohsiungAges 18–65 - NCT07476313Enrolling by invitation
Testing a new home sleep system for moderate to severe sleep apnea
This study tests a home sleep testing system called SleepView+ in people who have already been scheduled for an overnight sleep lab study. If you have moderate to severe obstructive sleep apnea, this device might offer a more convenient way to monitor your sleep at home.
Redwood City, CaliforniaAges 12 years+ - 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+ - NCT07169058Enrolling by invitation
Hands-on therapy for sleep apnea: a gentle technique
This study tests a gentle manual therapy applied to the neck to see if it can improve breathing and vital signs during sleep. It is for people with moderate to severe sleep apnea who are not currently using a CPAP machine or other breathing devices.
Mardin, MardinAges 18–65 - NCT07149233Enrolling by invitation
Breathing muscle training for sleep apnea patients
This trial tests whether training the muscles you use to breathe can improve sleep for people with moderate to severe obstructive sleep apnea. It is for adults who are not currently receiving standard treatments like CPAP.
Recife, PernambucoAges 18–70 - NCT07124975Enrolling by invitation
Comparing CPAP use feedback to improve treatment
This trial tests if showing your CPAP usage alongside other users helps you use it more. You'll get monthly mail with your usage data, and possibly others' data, for six months.
Kyoto, KyotoAges 20 years+ - 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+ - 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 - 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.
