Recruiting studies
- NCT05147649Recruiting

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 - NCT06681974RecruitingPhase 3
Throat therapy for sleep apnea without CPAP
This trial tests a type of mouth and throat therapy to see if it can help people with mild to moderate sleep apnea who can't or don't want to use a CPAP machine. It might be an option if you want a non-machine treatment for your sleep apnea.
SantanderAges 18–70 - NCT07581938Recruiting
Early Dental Screening for Sleep Problems in Kids
This study uses a smartphone app and a wearable device to check for early signs of sleep-disordered breathing—a condition where breathing stops briefly during sleep—in children ages 8–13. The goal is to catch dental and jaw problems that might lead to sleep issues before they become serious.
Chapel Hill, North CarolinaAges 8–13 - NCT06519149Recruiting
Device for sleep apnea without CPAP
This trial tests a device placed in your mouth during sleep to treat obstructive sleep apnea. It may be an option if you cannot or do not want to use a CPAP machine.
Austin, TexasAges 18 years+ - 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 - 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+ - 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 - NCT06851338Recruiting
Inspire therapy study for teens with Down syndrome and sleep apnea
This study tests a device called Inspire that stimulates the airway during sleep to treat obstructive sleep apnea in teenagers with Down syndrome who cannot use a CPAP machine or had a tonsillectomy that did not work well.
Phoenix, ArizonaAges 13–18 - NCT06896448Recruiting
Sleep apnea screening for head and neck cancer patients
This study tests a smartphone app (Apneal) to screen for sleep apnea in people who are being checked for head and neck cancer. It aims to find sleep problems early so they can be treated.
Caen, FranceAges 18 years+ - NCT06960746Recruiting
Lifestyle change for sleep apnea, metabolic syndrome, and impotence
This trial tests whether changing your lifestyle can help men with sleep apnea, metabolic syndrome, and erectile dysfunction. It studies how improving diet and exercise might improve these conditions together.
Giza, DokkiAges 40–50 - NCT06514482Recruiting
Spanish sleep apnea and daytime sleepiness registry
This study will collect information from people with suspected sleep apnea who feel very sleepy during the day. If you are 18 or older and about to have a sleep study, you may be able to help researchers learn more about this condition.
Logroño, La RiojaAges 18 years+ - NCT06994650RecruitingPhase 3
Study of HRS9531 for sleep apnea and obesity
This trial tests an injection called HRS9531 to see if it helps people with obstructive sleep apnea (OSA) and obesity who already use a CPAP or similar breathing device. It may help by reducing weight and improving breathing during sleep.
Beijing, Beijing MunicipalityAges 18–75 - NCT06931028RecruitingPhase 3
Study of IBI362 for sleep apnea with obesity
This study tests an investigational medication (IBI362) to see if it can improve sleep apnea in people with obesity. You might qualify if you have moderate to severe sleep apnea and a BMI of 28 or higher, whether or not you currently use a CPAP machine.
BeijingAges 18 years+ - NCT07823608RecruitingPhase 3
Monthly study medicine for adults with sleep apnea and overweight who use a breathing machine
This study tests an investigational medicine taken once a month for adults with moderate to severe sleep apnea who are overweight or have obesity and use a CPAP or similar breathing machine. It aims to see if the medicine improves sleep-related breathing.
Cullman, AlabamaAges 18 years+ - 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 - NCT06477952RecruitingPhase 1/Phase 2
Dronabinol for sleep apnea
This study tests whether dronabinol, a cannabis-like medicine, can help people with moderate sleep apnea breathe better at night. It may be an option for those who haven't found other treatments helpful.
Chicago, IllinoisAges Up to 65 years - NCT05838183Recruiting
Test treatment in people with lung disease and sleep apnea
This trial is studying how a treatment may work for adults who have interstitial lung disease or obstructive sleep apnea. It likely involves sleep testing so the team can measure breathing and sleep patterns.

Common questions
- Are there clinical trials for sleep apnea syndrome (osas)?
- Yes. Clin2 currently lists 84 recruiting sleep apnea syndrome (osas) 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 syndrome (osas) 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 syndrome (osas) 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.
