Recruiting studies
- 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+ - NCT06117579Recruiting
Breathing Muscle Training for Sleep Apnea
This trial tests whether a simple breathing exercise (training the muscles you use to breathe in) can improve sleep apnea symptoms in people who already use CPAP. The goal is to see if adding this training helps you feel better or need less CPAP pressure.
OrléansAges 18 years+ - NCT06043440RecruitingPhase 2
Oxygen therapy for sleep apnea in Down syndrome
This study tests whether oxygen therapy can help children with Down syndrome who have sleep apnea. It compares oxygen treatment to no treatment to see if it improves breathing during sleep and thinking skills.
Los Angeles, CaliforniaAges 5–18 - NCT05953610RecruitingPhase 2
Surgery study for sleep apnea when CPAP won’t work
This Phase 2 trial tests whether a specific type of palate surgery can treat moderate-to-severe obstructive sleep apnea in people who cannot tolerate CPAP (a breathing mask). It also checks patient traits (based on sleep testing) to see who is most likely to benefit from surgery.
Santa Monica, CaliforniaAges 21 years+ - NCT05911646Recruiting
Tool to help decisions for mild sleep apnea in kids
This trial looks at OSA-18, a questionnaire that may help families and clinicians make better decisions about treatment for a child’s mild sleep apnea. It specifically focuses on children with enlarged tonsils and mild sleep study results.
Hartford, ConnecticutAges 3–12 - 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 - NCT05147649Recruiting
Brain scan study in severe sleep apnea without CPAP
This trial uses a specialized brain scan (MRI) to study people with severe obstructive sleep apnea who are not using CPAP. It also compares them with people who do not have sleep apnea to understand how brain function differs.
ReimsAges 18–75 - 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 - NCT05575401Recruiting
Track surgery results in kids getting tonsil removal
This trial looks at how well a specific throat surgery technique works in children who are having their tonsils removed (with or without removing adenoids). It may help improve how doctors choose and perform surgery for safer, better recovery.
Murrieta, CaliforniaAges 3–17 - NCT05508971Recruiting
Personalized tonsil surgery for sleep apnea in children with Down syndrome
This study tests whether a personalized surgical approach can treat moderate to severe obstructive sleep apnea (OSA) in children with Down syndrome. The goal is to improve breathing during sleep and overall sleep health.
Aurora, ColoradoAges 2–17 - NCT05539716Recruiting
Treating sleep apnea to study effects on metabolism
This study tests a sleep apnea treatment approach and looks at how it may affect your body’s metabolism. You may be eligible if you’re an adult with sleep apnea and meet health and medication rules, and possibly if you already use a PAP machine regularly.
Miami, FloridaAges 18–70 - 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 - NCT05497180RecruitingPhase 1
Testing an oral device to reduce snoring and mild sleep apnea
This Phase 1 study tests whether a passive mouth/oral appliance can lessen snoring and mild obstructive sleep apnea. It may help you by improving airflow during sleep without other intensive treatments.
Edmonton, AlbertaAges 18 years+ - NCT05382754Recruiting
Home sleep testing for children being checked for sleep apnea
This trial tests whether home sleep testing can help diagnose sleep apnea in children. It is for kids who are already being referred for an in-lab sleep study at CHOP.
Philadelphia, PennsylvaniaAges 5–12 - NCT05237505RecruitingPhase 2
Sleep apnea plus COPD study to check heart and breathing effects
This Phase 2 study looks at the cardiovascular (heart/blood vessel) effects of having both sleep apnea and COPD. It may help doctors better understand who is at risk and how to manage these breathing problems together.
La Jolla, CaliforniaAges 40–79 - 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+ - NCT02703207Recruiting
Sleep apnea and COPD effects in older veterans
This study looks at how sleep apnea affects thinking skills and overall health in older veterans who also have COPD. It may help researchers understand what changes to target to improve daytime functioning and wellbeing.
Detroit, MichiganAges 60–89 - NCT07332780Recruiting
Tonsil and adenoid surgery for kids with mild breathing troubles during sleep
This study looks at whether removing tonsils and adenoids can help improve spine curves in children who have mild sleep-disordered breathing. It may help prevent scoliosis from getting worse.
Wenzhou, ZhejiangAges 6–15 - 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+ - 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 - NCT05115968Recruiting
Study tonsil cell changes in children with sleep apnea
This study uses a lab method called single-cell sequencing to look at tiny cells from tonsil tissue in children. It compares children with obstructive sleep apnea to children without it, to better understand what’s happening in the throat and how it may relate to needing tonsil removal.
Hong KongAges 6–11 - NCT07362706Enrolling by invitation
Extended breathing tube use for stomach cancer with sleep apnea
This trial looks at keeping a breathing tube in longer after stomach cancer surgery for patients who also have severe sleep apnea. The goal is to see if this helps with recovery and safety.
Jinan, ShandongAges 18–85 - NCT06792188Recruiting
Using a smartwatch to predict sleep apnea
This trial tests if a smartwatch can help predict sleep apnea in people who have symptoms like snoring or daytime sleepiness. It may offer a simpler way to identify the condition.
