Sleep apnea treatments for people who can't use CPAP
This study is comparing two alternative treatments for moderate to severe sleep apnea in people who cannot or will not use a CPAP machine. The treatments are a custom-fitted dental device and a nerve stimulation implant, and the study will see how well they work.
St Louis, MissouriAges 18 years+ - NCT07132307Recruiting
Mouthpiece help after failed sleep apnea nerve stimulator
This study tests whether adding a special mouthpiece (mandibular advancement device) can help people whose sleep apnea wasn't fully treated by a nerve stimulator implant. You would use the mouthpiece at night and take home sleep tests to see if your breathing improves.
St Louis, MissouriAges 18–70 - NCT07226765RecruitingPhase 3
Study of an injectable medicine for sleep apnea in people not using breathing devices
This trial tests an injectable medicine (maridebart cafraglutide) versus a placebo to see if it helps reduce sleep apnea episodes in people who do not use or cannot use a CPAP or similar breathing machine. It may be an option if you have moderate to severe sleep apnea and are looking for a non-device treatment.
Northridge, CaliforniaAges 18–99 - NCT07307560Recruiting
High-flow oxygen during sedation for sleep apnea patients having endoscopy
This study tests if high-flow nasal oxygen can prevent oxygen drops during sedated endoscopy in patients with severe obstructive sleep apnea. It may help people who are at higher risk of breathing problems during the procedure.
Hangzhou, ZhejiangAges 18 years+ - NCT07120711Recruiting
Sleep apnea, thinking, and mood study for kids and adults
This study looks at how sleep apnea affects thinking and mood by checking certain proteins in the body. They want to see if these proteins can help predict or explain changes in memory, focus, or emotions.
ShanghaiAges 5 years+ - NCT06944782Recruiting
Can mouth muscle tests help diagnose sleep apnea?
This study tests a new device that measures muscle activity in your mouth to diagnose sleep apnea—without needing to spend the night in a lab. If you've already had a sleep test showing either no sleep apnea or moderate to severe sleep apnea, and you're not using CPAP daily, you may be able to help.
San Diego, CaliforniaAges 18–80 - NCT07387094RecruitingPhase 3
A study of XW003 for obesity with sleep apnea (no CPAP)
This trial tests an investigational weekly injection called XW003 for weight loss in people who have obesity and moderate-to-severe sleep apnea but do not use a CPAP machine. It aims to see if the drug can help with weight loss and improve sleep apnea without the need for a breathing machine.
Beijing, Beijing MunicipalityAges 18–75 - 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.
