Test accuracy using a scope-based feeling test for sleep apnea
This study checks how accurately a special camera/scope test can measure throat sensation in people being evaluated for obstructive sleep apnea (OSA). If the test works well, it may help improve how clinicians understand and assess OSA-related changes.
Bogotá, Bogota D.C.Ages 18 years+ - NCT03736382Recruiting
Study how mild low-oxygen affects sleep apnea and blood pressure
This trial studies whether mild, controlled low oxygen during sleep can change sleep apnea symptoms and related blood pressure issues. It mainly looks at people with newly diagnosed, untreated sleep apnea and early high blood pressure.
Detroit, MichiganAges 18–60 - 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+ - NCT04005508Recruiting
Study sleep apnea and heart outcomes in high-risk atrial fibrillation
This trial looks at how obstructive sleep apnea (OSA, a breathing problem during sleep) relates to heart outcomes in people with atrial fibrillation (AF). It may help doctors better predict risk and choose safer care for people who are high cardiovascular risk.
SingaporeAges 22–99 - NCT04092660Recruiting
Mouth guard study to reduce airway collapse in sleep apnea
This study tests whether using an anti-snoring mouth guard (a mandibular advancement appliance) can help keep your airway open during sleep if you have obstructive sleep apnea. If you’re referred for this kind of mouth guard, the trial will see if using it more regularly or in a specific way improves symptoms or breathing during sleep.
LondonAges 40–90 - 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+ - NCT04179981Recruiting
CPAP treatment effects in older COPD and sleep apnea patients
This study looks at whether using positive airway pressure (often called CPAP) improves health outcomes in older adults who have both COPD and obstructive sleep apnea. It may help find ways to reduce symptoms and complications from “overlap” breathing problems.
Detroit, MichiganAges 60 years+ - NCT04335994Recruiting
Home sleep testing for people with memory trouble
This study looks at how well home sleep apnea testing works for people with cognitive impairment (memory/thinking problems) to help improve outcomes. You may be asked to do a home sleep test (and possibly an in-lab test) and will involve a caregiver if needed.
Toronto, OntarioAges Any age - 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+ - NCT04603196Recruiting
Study sleep apnea in adults with multiple sclerosis
This study looks at how often sleep apnea happens in people who have multiple sclerosis, and how it affects daily life and health. You may be invited to participate if you’re an adult with a confirmed multiple sclerosis diagnosis and can consent to the study.
Boston, MassachusettsAges 18 years+ - NCT04658290Recruiting
Sleep apnea screening and memory test study
This study looks at how common obstructive sleep apnea is and whether it’s linked to thinking and memory problems. It may help clarify which people with sleep apnea might be more likely to have cognitive difficulties.
Hong Kong, Please SelectAges 40–74 - 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.
Hong Kong, Please SelectAges 18 years+ - NCT04675268Recruiting
Testing nighttime oxygen patterns in suspected sleep apnea
This study looks at how oxygen levels change during the night in people who might have obstructive sleep apnea (OSA). It may help doctors better understand breathing problems during sleep and improve how OSA is evaluated.
LeuvenAges 18 years+ - NCT04712656Recruiting
CPAP treatment for sleep apnea and blood pressure changes
This study tests whether using CPAP (a breathing machine) for obstructive sleep apnea can improve blood pressure and heartbeat timing. You’ll have blood pressure checked at the start and again after 6 months, along with a sleep evaluation to confirm eligibility.
Columbus, OhioAges 30–75 - NCT04814420Recruiting
Study heart scarring in sleep apnea, with or without atrial fibrillation
This pilot study looks at whether obstructive sleep apnea leads to heart scarring (called atrial fibrosis), especially in people with and without an irregular heart rhythm (atrial fibrillation). It may help researchers understand who is at higher risk and why, using sleep testing and heart imaging.
New Orleans, LouisianaAges 18–75 - 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 - NCT04991389RecruitingPhase 4
Test a breathing study plan for kids with sleep apnea after surgery
This trial studies how to improve outcomes for children who still have obstructive sleep apnea after having their tonsils and adenoids removed. It uses computer modeling (based on breathing/airflow) and may include a special breathing gas during testing in some parts of the study.
Cincinnati, OhioAges 3–18 - NCT05050383Recruiting
Study testing obstruction patterns to guide CPAP alternatives
This study looks at how breathing passages narrow during sleep to better understand obstruction patterns. It may help people who are being considered for alternatives to CPAP (a common breathing device) for sleep-disordered breathing.
Philadelphia, PennsylvaniaAges 18 years+ - 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
