Recruiting studies
- 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 - 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 - 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 - NCT05429983Recruiting
Predicts results from Inspire tongue-stimulation for sleep apnea
This study looks at how breathing mechanics during a sleep-related test (DISE) can help predict how well Inspire tongue (hypoglossal nerve) stimulation will work. It may help your care team choose the best approach and set expectations for improvement.
Baltimore, MarylandAges 18 years+ - NCT05527652Recruiting
Breathing tube device to help blocked upper airways in children
This study tests a self-supporting breathing tube placed through the nose during sleep to reduce upper airway blockage and improve breathing in children. It may help children who have sleep apnea symptoms, especially after tonsil/adenoid treatment or when tonsil removal isn’t possible.
Ann Arbor, MichiganAges 3–21 - NCT05536076Recruiting
Breathing treatment to help recovery after spinal cord injury
This study tests whether a breathing-support treatment (for abnormal breathing during sleep) can improve breathing recovery in people living with a spinal cord injury. It aims to see if treating higher carbon dioxide levels and sleep-breathing problems leads to better breathing and recovery.
Detroit, MichiganAges 18–89 - 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 - NCT05958563Recruiting
CPAP may prevent COPD flare-ups in COPD-OSA overlap
This study tests whether using continuous positive airway pressure (CPAP) can reduce acute COPD flare-ups in people who also have sleep apnea. It may help by improving breathing during sleep and lowering the chance of worsening lung symptoms.
AngersAges 40 years+ - NCT06015620Recruiting
Health changes after mini gastric bypass surgery
This study looks at how mini gastric bypass surgery helps with obesity-related health problems and changes in body composition. It aims to see if patients experience improvements in conditions like diabetes or high blood pressure.
Bhubaneswar, OdishaAges 18–65 - 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 - NCT06061562Recruiting
Sleep Apnea and Activity in Down Syndrome
This trial looks at whether physical activity can help improve sleep apnea in people with Down syndrome. It aims to find better ways to manage breathing problems during sleep.
La TroncheAges 6 years+ - NCT06115018Recruiting
Oral device for sleep apnea after palate surgery
This study tests whether a special oral device (OPR) can help people with sleep apnea after they have had palate surgery. It looks at how well it works and if the benefits last over time.
TainanAges 18–100 - NCT06132477RecruitingPhase 4
Study of GLP-1 medicines after weight loss surgery
This study looks at what happens when people taking a GLP-1 medication (like Ozempic) either stop or continue it after weight loss surgery. The goal is to learn whether staying on the medicine helps with long-term weight control.
Columbia, MissouriAges 18 years+ - NCT06169761Recruiting
Tongue strength test in healthy adults
This study measures tongue strength in healthy adults. It helps researchers understand normal tongue function, which may improve treatments for swallowing problems.
Louvain-la-NeuveAges 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+ - NCT06239883Recruiting
Sleep apnea and nighttime bathroom trips study
This study looks at how sleep apnea affects nighttime bathroom trips (nocturia). If you have sleep apnea and wake up often to urinate, you may be able to help researchers understand the link.
Ostrava, Moravian-Silesian RegionAges 18 years+ - NCT06247631Recruiting
Sleep apnea risk before chest surgery
This study uses a simple questionnaire (STOP-Bang) to check if patients having chest surgery might have undiagnosed sleep apnea or face breathing challenges during surgery. It helps doctors plan safer care.
Ankara, KeçiörenAges 18–65 - NCT06261034Recruiting
How sex affects blood pressure control
This study looks at how the nervous system controls blood pressure differently in men and women. It may help researchers understand why some heart conditions affect men and women differently.
Rochester, MinnesotaAges 20–70 - NCT06264427Recruiting
Study of metabolism issues in Greenland
This study looks at the genes and physical traits of people in Greenland with type 2 diabetes or severe obesity. It aims to better understand these conditions to improve care.

Common questions
- Are there clinical trials for sleep apnea?
- Yes. Clin2 currently lists 344 recruiting sleep apnea studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a sleep apnea trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a sleep apnea trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
