Nerve stimulation for sleep apnea in overweight adults
This trial tests a nerve stimulation treatment for obstructive sleep apnea in people who are overweight and cannot tolerate CPAP. It focuses on how the treatment affects metabolism and weight.
Chicago, IllinoisAges 18 years+ - NCT05558501RecruitingPhase 1/Phase 2
Intermittent low-oxygen therapy for sleep apnea and health risks
This early-stage study tests a treatment that briefly reduces oxygen during sleep to improve “plasticity,” with the goal of helping people with obstructive or mixed sleep apnea. It also looks at related conditions like high blood pressure and pre-diabetes or cholesterol problems, especially in people who haven’t tried CPAP yet.
Detroit, MichiganAges 30–60 - NCT04905238Enrolling by invitation
Sleep apnea study linking breathing markers to memory changes
This trial looks at how severe sleep apnea breathing patterns relate to body “biomarkers” linked to Alzheimer’s disease, using blood or other measures. It may help researchers understand whether sleep apnea is connected to memory and brain health—and who might benefit most from better sleep care.
Palma, Balearic IslandsAges 18–65 - NCT04603196Recruiting
Study sleep apnea in adults with multiple sclerosis
This study looks at how often sleep apnea happens in people who have multiple sclerosis, and how it affects daily life and health. You may be invited to participate if you’re an adult with a confirmed multiple sclerosis diagnosis and can consent to the study.
Boston, MassachusettsAges 18 years+ - NCT02431507Recruiting
First test of an implant device to prevent sleep apnea pauses
This trial is testing whether a new implanted device is safe and feasible for people with moderate to severe obstructive sleep apnea. It may help if you cannot tolerate CPAP (a common breathing device) and your apnea is caused by airflow blockage at the back of the tongue area.
San Francisco, CaliforniaAges 21–70 - 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+ - NCT07740213Enrolling by invitation
Sleep apnea study at Sohag University hospitals
This study looks at people who have obstructive sleep apnea (a condition where breathing stops briefly during sleep). It may help doctors understand this condition better and improve care for patients.
Sohag, Sohag GovernorateAges 18 years+ - NCT07434050RecruitingPhase 3
Study of XW003 for obesity with sleep apnea on CPAP therapy
This trial tests an investigational drug called XW003 to see if it helps people with obesity and obstructive sleep apnea who are already using a positive airway pressure (PAP) machine, like CPAP. It aims to improve weight loss and sleep apnea symptoms.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06994247Recruiting
Boosting CPAP use in severe sleep apnea
This study tests whether motivation and psychological support can help people with severe sleep apnea use their CPAP machine more consistently over three months.
Split, DalmatiaAges 18 years+ - NCT06312956Recruiting
Sleep Apnea and Ventilotherapy: A Study Before and After Treatment
This trial studies how sleep apnea affects the body and brain before and after starting treatment with a breathing device (ventilotherapy). It aims to understand the benefits of early treatment for people with obstructive sleep apnea.
Piancavallo, VCOAges 20–60 - NCT04814420Recruiting
Study heart scarring in sleep apnea, with or without atrial fibrillation
This pilot study looks at whether obstructive sleep apnea leads to heart scarring (called atrial fibrosis), especially in people with and without an irregular heart rhythm (atrial fibrillation). It may help researchers understand who is at higher risk and why, using sleep testing and heart imaging.
New Orleans, LouisianaAges 18–75 - NCT02922894RecruitingPhase 4
Testing sleep apnea care in people with spinal cord injury
This study looks at treatment for sleep apnea (breathing pauses during sleep) in adults with a spinal cord injury. If you qualify, the trial team may help manage sleep-related breathing problems and track how well the treatment works.
Detroit, MichiganAges 18–89 - 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.

Common questions
- Are there clinical trials for sleep apnea?
- Yes. Clin2 currently lists 328 recruiting 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 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 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.
