This trial studies whether a person’s decision-making skills affect how well they use CPAP, a common treatment for sleep apnea. It may help you and your care team improve CPAP adherence so therapy is more effective.
PaviaAges 18–80 - 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+ - 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 - NCT05156112Recruiting
PAP breathing treatment for veterans with PTSD and substance use
This trial studies whether using a PAP breathing device (a machine that helps keep airways open during sleep) can help veterans who have PTSD and a substance use disorder while they receive residential treatment. It’s specifically for people with obstructive sleep apnea and aims to see if this treatment is safe and helpful during recovery.
San Diego, CaliforniaAges 18 years+ - NCT05262439Recruiting
Follow-up study of CPAP mask systems for sleep apnea
This study checks how ResMed CPAP mask systems work in real-life use for people with obstructive sleep apnea (OSA). It may help improve comfort, fit, and performance based on what patients experience over time.
Sydney, New South WalesAges 18–100 - NCT05267808Recruiting
Using sleep study patterns to guide future OSA treatment
This study looks at results from a sleep test to better understand the different types (“endotypes”) of obstructive sleep apnea. Your information may help doctors choose the next best step—often a procedure called drug-induced sleep endoscopy (DISE)—to guide treatment.
EdegemAges 18 years+ - NCT05293600RecruitingPhase 1/Phase 2
Rescue medicine trial for sleep apnea after other treatments fail
This trial studies a “rescue” set of medicines for obstructive sleep apnea when two common treatments haven’t worked well enough. If you still have frequent breathing pauses during sleep, the study may test whether these medicines can reduce them and improve safety and symptoms.
Boston, MassachusettsAges 21–70 - NCT05315752Recruiting
Body fat changes after CPAP-treated sleep apnea improves
This study looks at how bariatric (weight-loss) surgery may change body fat and body shape in people with severe obstructive sleep apnea who use CPAP. It aims to understand what may improve when sleep apnea is better controlled after surgery.
BrusselsAges 18–99 - NCT05350332Recruiting
Testing how lung air volume affects airway narrowing during sleep testing
This study looks at whether changing lung air volume affects how open or blocked your upper airway is during a drug-induced sleep test (DISE). It may help guide surgical choices for people with obstructive sleep apnea (OSA).
Atlanta, GeorgiaAges 18 years+ - NCT05391945Recruiting
Thyroid surgery and sleep apnea in people with goiters
This trial studies whether planned thyroidectomy (thyroid surgery) changes obstructive sleep apnea (breathing pauses during sleep) in people who have a goiter. It may help doctors understand whether treating the thyroid affects nighttime breathing.
BrusselsAges 18–90 - NCT05656365Recruiting
Study of genes and immunity in PFAPA and other tonsil problems
This study looks at genetic markers and immune system patterns in people with PFAPA (periodic fevers with mouth sores and throat/neck gland symptoms) or similar tonsil problems. It may help researchers understand why these conditions happen and how they might be better diagnosed or treated.
Washington D.C., District of ColumbiaAges 1 month–99 years - NCT05917119Recruiting
Bright light therapy for obstructive sleep apnea symptoms
This study tests whether a “bright light” treatment can reduce daytime sleepiness in people with obstructive sleep apnea who are already using CPAP or BiPAP. It may help people feel more awake during the day without changing their sleep apnea device use.
Pittsburgh, PennsylvaniaAges 40–65 - NCT05986487Recruiting
Sleep apnea treatment for better blood pressure control
This trial tests whether treating sleep-disordered breathing (like sleep apnea) can help lower blood pressure in people with high blood pressure. You may join if you have high blood pressure and haven't been diagnosed with a sleep disorder before.
LleidaAges 18 years+ - NCT06047353Recruiting
Helping people with sleep apnea try PAP therapy for the first time
This study tests whether health advocates can help people with moderate-to-severe sleep apnea start using a PAP machine. If you've never used a PAP or other sleep apnea treatment before, this trial may help you get support and guidance.
Miami, FloridaAges 18–100 - NCT06115018Recruiting
