Boston, MassachusettsAges 21–70 - NCT03109171Recruiting
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+ - NCT03858751RecruitingPhase 1/Phase 2
Drug to activate a sleep-control pathway for sleep apnea
This early study tests a medicine that is meant to improve how your brain and breathing muscles work during sleep for obstructive sleep apnea (OSA). If you qualify, you would be monitored during sleep to see whether the treatment changes breathing events and oxygen levels.
Boston, MassachusettsAges 18–70 - 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+ - NCT03929549Recruiting
Testing a tool to predict jaw surgery failure for sleep apnea
This trial studies a way to predict which people with obstructive sleep apnea (OSA) may not do well after maxillomandibular advancement surgery (jaw advancement). It could help doctors choose the right treatment and avoid ineffective surgery.
Ann Arbor, MichiganAges 30–65 - 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 - 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+ - NCT04192656RecruitingPhase 4
PAP treatment for sudden hearing loss with sleep apnea
This trial tests whether using PAP (a breathing device for sleep apnea) can improve sudden hearing loss that happens alongside obstructive sleep apnea. It may help by reducing stress on the body during sleep and supporting hearing recovery.
Beijing, Beijing MunicipalityAges 18–70 - 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 - 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+ - 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 - NCT04675268Recruiting
