Toronto, OntarioAges 18 years+ - NCT04031950Recruiting
Testing a sleep sensor for children suspected of sleep apnea
This study tests a child sleep “sensor” device in kids who have been referred to a sleep clinic because sleep apnea is suspected. It may help doctors diagnose sleep problems more easily using extra information from the sensor.
SheffieldAges 1–18 - NCT04092660Recruiting
Mouth guard study to reduce airway collapse in sleep apnea
This study tests whether using an anti-snoring mouth guard (a mandibular advancement appliance) can help keep your airway open during sleep if you have obstructive sleep apnea. If you’re referred for this kind of mouth guard, the trial will see if using it more regularly or in a specific way improves symptoms or breathing during sleep.
LondonAges 40–90 - NCT04114084Recruiting
Sleep apnea study in people with MGUS or multiple myeloma
This study looks at sleep apnea (breathing pauses during sleep) in people who have MGUS or multiple myeloma. You may be asked to participate because you already need a bone marrow biopsy as part of your usual care.
Iowa City, IowaAges 18–99 - NCT04190953Recruiting
Braces and expanders in kids to improve airflow space
This study looks at how jaw and palate treatments affect airflow through the upper airway in children with a specific bite and jaw shape. It may help researchers understand which treatments improve space for breathing and related pressure changes.
Edmonton, AlbertaAges 8–14 - NCT04192656RecruitingPhase 4
PAP treatment for sudden hearing loss with sleep apnea
This trial tests whether using PAP (a breathing device for sleep apnea) can improve sudden hearing loss that happens alongside obstructive sleep apnea. It may help by reducing stress on the body during sleep and supporting hearing recovery.
Beijing, Beijing MunicipalityAges 18–70 - NCT04430790RecruitingPhase 3
Doxapram for apnea in very preterm babies on breathing support
This trial studies whether the medicine doxapram can better treat breathing pauses (apnea) in very preterm babies who are already on breathing support in the NICU. It aims to reduce the need for extra interventions and improve outcomes in this high-risk group.
Brussels, Avenaue Hippocrate 10Ages 5 months–7 months - NCT04457154Recruiting
Registry for teens and young adults with OSA who can’t use CPAP
This study collects information in a registry to help doctors understand outcomes for young people with moderate-to-severe obstructive sleep apnea who cannot use CPAP and may use an implantable breathing stimulation device. You might qualify if you’ve tried and couldn’t tolerate CPAP and you’re able/willing to get and use the device and return for follow-ups and sleep tests.
Aurora, ColoradoAges 18–21 - NCT04557293Recruiting
Testing how thinking decisions affect CPAP use
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 - NCT04606693Recruiting
Screening for sleep apnea before heart rhythm ablation
This study looks at whether checking for sleep apnea (breathing pauses during sleep) and treating it helps people prepare for atrial fibrillation ablation. It may help by improving outcomes for patients with atrial fibrillation who keep having episodes despite medication.
Madrid, MadridAges 18 years+ - 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 - NCT05050383Recruiting
Study testing obstruction patterns to guide CPAP alternatives
This study looks at how breathing passages narrow during sleep to better understand obstruction patterns. It may help people who are being considered for alternatives to CPAP (a common breathing device) for sleep-disordered breathing.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05127720Recruiting
Pacemaker monitoring to study sleep apnea long term
This study uses a pacemaker to track information over time related to sleep apnea. It also includes CT scans to help the researchers better understand what’s happening in and around the heart during sleep.
Innsbruck, TyrolAges 18 years+ - 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+ - NCT05197738Recruiting
Study using a sleep health app to improve sleep
This study tests a “sleep health” app (REFRESH) to see how it may help people track and improve sleep. You may be eligible if you’re an adult in the U.S. who can use the app on your own phone.
La Jolla, 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 - NCT05298748Recruiting
Audio recordings to help breathing control mature in preterm babies
