Calgary, AlbertaAges 18–45 - NCT02784977Recruiting
Sleep apnea study using a national sleep database
This study collects information from adults who are getting a sleep test because obstructive sleep apnea is suspected. It helps researchers better understand sleep apnea and who develops it, without giving a new treatment.
IstanbulAges 18–80 - NCT06089096Recruiting
Sleep apnea and memory in people with mild memory problems
This study looks at whether sleep apnea (pauses in breathing during sleep) is linked to thinking and memory in people who have mild memory problems. You will do a home sleep test and take memory tests to help researchers find this connection.
Hong KongAges 18 years+ - NCT03948373Recruiting
Study of sleep apnea patients with normal blood pressure
This study is looking at a specific sleep-related condition (obstructive sleep apnea) in adults whose blood pressure is not high, and how their blood pressure rhythm changes over the day. If you have sleep apnea, participating could help researchers understand patterns that may affect long-term health.
LleidaAges 18–100 - 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+ - NCT05978505RecruitingPhase 2
Reboxetine for sleep apnea after ENT surgery
This study tests if the medication reboxetine helps reduce sleep apnea symptoms after planned upper airway surgery. It may be a good fit if you have sleep apnea and are having surgery on your nose or throat.
Bedford Park, South AustraliaAges 18 years+ - NCT06386341Recruiting
Quality of life after MMA surgery for sleep apnea
This study looks at how maxillomandibular advancement (MMA) surgery affects quality of life in people with obstructive sleep apnea (OSA). It aims to see if the surgery helps improve sleep and daily well-being.
UtrechtAges 18 years+ - NCT06609694Recruiting
Comparing oxygen delivery methods for children with sleep apnea
This study tests a new way to give oxygen to children aged 5-17 who have obstructive sleep apnea (a condition where breathing stops briefly during sleep). It aims to see if a demand oxygen delivery system works better than standard care. This could help children with Down syndrome who often have untreated sleep apnea.
Cincinnati, OhioAges 5–17 - NCT06789770Recruiting
Nasal vs mouth breathing during drug-induced sleep
This study compares how breathing through the nose versus mouth affects sleep, using both natural and medication-induced sleep. It may help people with sleep apnea understand their breathing patterns better.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07176767Recruiting
Sleep study on insomnia and mask use in kids
This study looks at how insomnia affects how well children and teenagers use their breathing mask (PAP therapy) for sleep apnea. It aims to find ways to help kids stick with their treatment.
Vancouver, British ColumbiaAges 8–18 - NCT07136909Recruiting
Testing a sleep apnea questionnaire for French children
This study is testing a French questionnaire (OSA-18) to see if it helps screen for sleep apnea in kids. It may lead to easier detection of breathing problems during sleep.
Bron, RhôneAges 4–17 - NCT07009535Enrolling by invitation
Sleep apnea risk and orthodontic issues in children
This study looks at how narrow upper jaws (maxillary constriction) relate to sleep apnea in children with mixed teeth. It aims to understand if dental problems affect breathing during sleep and guide future treatments.
Pavia, LombardyAges 6–12 - NCT06786117Enrolling by invitation
Swallowing therapy study for sleep apnea patients
This study tests whether daily swallowing exercises can help people with sleep apnea who cannot tolerate CPAP therapy. It compares three groups: healthy people, successful CPAP users, and those who have difficulty using CPAP.
Cleveland, OhioAges 40–70 - NCT06763549Enrolling by invitation
AI-powered wearable patch for heart and lung monitoring
This study tests an AI-powered wearable patch (the COR ECG) to see if it can better track heart and lung health. It may help doctors find problems earlier without needing bulky equipment.
Melbourne, FloridaAges 18 years+ - NCT06030349Recruiting
Breathing support for kids with Down syndrome and sleep apnea
This trial looks at how well non-invasive breathing machines help children with Down syndrome who have obstructive sleep apnea. It tracks their health and sleep over time to see if the treatment works and improves daily life.
DublinAges 6 months–16 years - NCT07121452Recruiting
Telehealth vs. standard care for sleep apnea in military families
This study compares a telehealth sleep-apnea program to standard care for people newly diagnosed with sleep apnea who are referred to private doctors in the TRICARE network. It aims to see if telehealth is just as effective and more convenient for military families.
Bethesda, MarylandAges 18–64 - NCT07357272Recruiting
Blood pressure benefits in sleep apnea patients after CPAP
This trial studies whether CPAP treatment can improve blood pressure in people with obstructive sleep apnea. It aims to find out who benefits most from CPAP in terms of blood pressure control.

Study on immune status and disease control in inflammatory airway diseases
This study looks at how the immune system works and how well diseases like asthma, COPD, and others are controlled. You may join if you have one of these conditions or if you are a healthy volunteer or smoker without lung disease.
Ningbo, ZhejiangAges 18 years+ - NCT06861686Recruiting
New classification for obstructive sleep apnea

Common questions
- Are there clinical trials for apnea, obstructive?
- Yes. Clin2 currently lists 302 recruiting apnea, obstructive 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 apnea, obstructive 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 apnea, obstructive 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.
