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.
Nuuk, SermersooqAges 18 years+ - NCT06286189RecruitingPhase 1/Phase 2
Testing trazodone for sleep apnea
This trial tests whether the medication trazodone can help people with moderate to severe obstructive sleep apnea (OSA). If you have OSA and are not taking certain medications or have other sleep disorders, you may be able to join.

This study looks at what happens to your thinking and daily health after COVID-19, especially if you have sleep apnea. It aims to find out who is more likely to have ongoing problems.
Detroit, MichiganAges 18 years+ - NCT05350215RecruitingPhase 1/Phase 2
Testing atomoxetine and DAW2022 for obstructive sleep apnea severity
This study tests whether atomoxetine and DAW2022 can improve how severe obstructive sleep apnea is. It may help by changing breathing patterns during sleep, measured through physiology tests.
Boston, MassachusettsAges 21–70 - NCT06334601Recruiting
Sleep apnea test to measure airway collapse and muscle response
This study looks at how the upper airway collapses and how muscles respond in people with obstructive sleep apnea (OSA) during sleep. It may help researchers understand why some treatments work better for some people.
MilanAges 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+ - NCT06413420Recruiting

Common questions
- Are there clinical trials for obstructive sleep apnea?
- Yes. Clin2 currently lists 310 recruiting obstructive 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 obstructive 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 obstructive 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.
