Sleep Apnea clinical trials are recruiting across 112 cities. Here are the cities with the most active studies:
Sleep Apnea Trial Phases
66 research organizations are sponsoring sleep apnea trials.
About Sleep Apnea
Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts during sleep. Obstructive sleep apnea (OSA) is the most common form. Treatment includes CPAP therapy, oral appliances, lifestyle changes, and in some cases surgery.
Clinical trials are advancing new treatments for sleep apnea. Currently, 100 studies are recruiting a combined 44,384 participants across the United States. Research is being conducted by 66 organizations including University of North Carolina, Chapel Hill, Ohio State University, The George Washington University Biostatistics Center and 63 others.
2026 Sleep Apnea Research Landscape
As of July 2026, the sleep apnea clinical trial landscape includes 100 actively recruiting studies across 112 cities in the United States. These studies are collectively seeking 44,384 participants, with an average enrollment target of 444 per study.
The research spans multiple phases of development: 35 studies are in NA, 21 studies are in PHASE2, 9 studies are in PHASE3, 7 studies are in PHASE1, 6 studies are in PHASE4, 1 study is in EARLY_PHASE1. The presence of Phase 3 trials indicates that some sleep apnea treatments are in late-stage testing and may be approaching regulatory review.
Research is being led by 66 different organizations, including University of North Carolina, Chapel Hill, Ohio State University, The George Washington University Biostatistics Center, National Cancer Institute (NCI), Eli Lilly and Company, and 61 others. The large number of sponsors reflects significant research interest and investment in sleep apnea treatment advancement.
Geographically, sleep apnea trials are most concentrated in New York, New York (8 trials); Philadelphia, Pennsylvania (8 trials); Chicago, Illinois (7 trials); Miami, Florida (7 trials); Boston, Massachusetts (7 trials) and 7 other cities.

Eating Disorders Genetics Initiative 2
The overarching intention of the Eating Disorder Genetics Initiative 2 (EDGI2) is to increase sample size, diversity, and eating disorder phenotypes. The investigators are enrolling 20,000 new participants with anorexia nervosa (AN), bulimia nervosa (BN), binge-eating disorder (BED), avoidant/restrictive food intake disorder (ARFID), and controls in the US, Mexico, Australia, New Zealand, Sweden, ...
Effects of CPAP Therapy on Blood Pressure and Heart Rate Variability in Obstructive Sleep Apnea
The primary objective of this study is to determine whether the effect of continuous positive airway pressure (CPAP) therapy on 24-hour mean blood pressure (BP) in patients with obstructive sleep apnea (OSA) varies between symptom phenotypes.
Continuous Positive Airway Pressure (CPAP) for Sleep Apnea in Pregnancy
A randomized controlled trial of 1,500 women to assess whether treatment of obstructive sleep apnea with continuous positive airway pressure (CPAP) in pregnancy will result in a reduction in the rate of hypertensive disorders of pregnancy.
