Long-term nose tube study for children with weak muscle tone
This study looks at the long-term safety and effectiveness of a nose tube (nasopharyngeal airway) for children who have obstructive sleep apnea due to weak muscle tone. It's for children who already used this device in a previous study.
Ann Arbor, MichiganAges 3–23 - NCT06566820Enrolling by invitationPhase 3
Long-term follow-up for sleep apnea study
This is a follow-up study for people with obstructive sleep apnea who have already completed two prior studies with the same medicine. The goal is to keep tracking your health and the medicine's effects over a longer time.
Birmingham, AlabamaAges 18 years+ - 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 - NCT05606991Enrolling by invitation
Testing how CPAP affects brain waste clearance during sleep
This study looks at how stopping CPAP for 14 nights affects “brain waste clearance,” a process your brain uses to clear byproducts during sleep. It is testing whether using CPAP versus stopping it changes this brain cleanup in adults with severe obstructive sleep apnea (OSA).
Macquarie Park, New South WalesAges 35–65 - NCT04129229Enrolling by invitation
Tongue device study for moderate-to-severe sleep apnea and snoring
This trial tests a tongue retractor device to help treat obstructive sleep apnea and reduce snoring in adults. You may be eligible if you have moderate-to-severe sleep apnea and can avoid other common treatments during the study.
Brighton, MassachusettsAges 18 years+ - 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.
Hershey, PennsylvaniaAges 18 years+ - NCT06564896Recruiting
Comparing sleep apnea treatments (CPAP vs alternatives)
This trial compares different positive airway pressure (PAP) machines to see which works best for people with moderate to severe sleep apnea. If you have been diagnosed but haven't used a CPAP yet, this study may help find the best option for you.
Cheras, Kuala LumpurAges 18 years+ - NCT05978505RecruitingPhase 2
Reboxetine for sleep apnea after ENT surgery
This study tests if the medication reboxetine helps reduce sleep apnea symptoms after planned upper airway surgery. It may be a good fit if you have sleep apnea and are having surgery on your nose or throat.
Bedford Park, South AustraliaAges 18 years+ - NCT06227572Recruiting
Thinking and memory after sleep apnea treatment in Native Americans
This study looks at whether using a PAP (breathing) machine helps thinking and memory in Native American adults with sleep apnea. If you are 50 or older and just starting PAP therapy, researchers want to see how it affects your brain health.
Eagle Butte, South DakotaAges 40 years+ - NCT06334601Recruiting
Sleep apnea test to measure airway collapse and muscle response
This study looks at how the upper airway collapses and how muscles respond in people with obstructive sleep apnea (OSA) during sleep. It may help researchers understand why some treatments work better for some people.
MilanAges 18 years+ - NCT06542263Recruiting
CPAP for preventing AF recurrence after ablation in people with AF and sleep apnea
This study tests whether using a CPAP machine at night can help prevent atrial fibrillation from coming back after a heart procedure called catheter ablation. It is for people who have both AF and moderate to severe obstructive sleep apnea.
Suzhou, JinagsuAges 18 years+ - NCT07136909Recruiting
Testing a sleep apnea questionnaire for French children
This study is testing a French questionnaire (OSA-18) to see if it helps screen for sleep apnea in kids. It may lead to easier detection of breathing problems during sleep.
Bron, RhôneAges 4–17 - NCT03948373Recruiting
Study of sleep apnea patients with normal blood pressure
This study is looking at a specific sleep-related condition (obstructive sleep apnea) in adults whose blood pressure is not high, and how their blood pressure rhythm changes over the day. If you have sleep apnea, participating could help researchers understand patterns that may affect long-term health.
LleidaAges 18–100 - NCT04623463Recruiting
Exercise and how it affects sleep apnea severity
This study looks at whether regular physical activity can make obstructive sleep apnea (OSA) less severe. It focuses on people who are not yet receiving OSA treatment and checks changes in severity over time.
GrenobleAges 18–80 - NCT04630535Recruiting
Using brief arm treatment before bypass surgery
This trial studies whether a simple, remote “arm treatment” given before scheduled aorto-bifemoral bypass surgery can help protect blood flow during surgery. If you fit the surgery plan and don’t have certain excluded conditions, the study may offer an added protective approach.
Brno, Czech RepublicAges 18 years+ - NCT06896448Recruiting
