SLEEP APNEA

This study investigates whether oxygen and the drug acetazolamide can help stabilize breathing during sleep in people who take prescription opioids and have sleep apnea. Researchers will measure breathing patterns and sleep quality in 150 veterans. The goal is to find new ways to…

This study tests a culturally tailored sleep program for Latino couples where one partner has sleep apnea and is starting CPAP therapy. The program includes three telehealth sessions teaching sleep skills and support strategies. Researchers want to see if it improves CPAP use and…

This study tests a device called the Lunair Alpha System, a neurostimulator implant that aims to treat moderate to severe sleep disordered breathing. It is for people who cannot use or do not tolerate other treatments like CPAP machines. The trial will check if the device is safe…

This study is testing a new implantable device called the Remede Dual Channel System for people with severe sleep apnea. The device is designed to stimulate nerves to keep the airway open during sleep. Researchers will check if the implant is safe and if it can reduce breathing p…

This study tests whether oxygen, acetazolamide, or finasteride can help treat sleep apnea in people aged 60 and older. Researchers will measure how these treatments affect breathing stability during sleep. The goal is to find better, more personalized options for elderly veterans…

This registry follows 225 adults with moderate-to-severe obstructive sleep apnea who receive the Inspire hypoglossal nerve stimulation implant. The device is for people who cannot use CPAP, the standard treatment. Researchers will measure how well it reduces breathing pauses duri…

This study tests three approaches—oxygen therapy, the drug trazodone, and brief low-oxygen episodes—to see if they can improve sleep apnea in people with chronic cervical spinal cord injury. Researchers will measure changes in breathing and sleep quality in 100 participants. The …

This study tests whether a sleep medication called eszopiclone can help people with obstructive sleep apnea use their CPAP machine more consistently and improve their thinking skills. About 250 adults with a new sleep apnea diagnosis will receive either eszopiclone or a placebo f…

This study tests whether a nasal spray of oxytocin, a natural hormone, can lower the air pressure needed from a CPAP machine in people with obstructive sleep apnea. Forty adults who already use CPAP will take the spray or a placebo before bed for 14 days. Researchers will measure…

This study tests whether daily treatments with slightly elevated carbon dioxide (hypercapnia) can improve breathing and reduce sleep apnea in Veterans with spinal cord injury. About 30 adults with chronic spinal cord injury or able-bodied people with sleep apnea will receive the …

This study tests whether taking nattokinase, a supplement made from fermented soybeans, can improve sleep quality, thinking skills, and heart health in people at risk for metabolic syndrome. About 80 adults will take either the supplement or a placebo for 12 weeks, then switch af…

This study tests whether bexagliflozin, a drug used for diabetes, can reduce the severity of obstructive sleep apnea in overweight or obese adults. Over 6 months, participants will take either the drug or a placebo and undergo sleep tests and body scans. The goal is to see if the…

This trial tests whether mailing a sleep apnea home-testing device to people with atrial fibrillation can improve their quality of life. About 936 participants will either receive the device and possible treatment, or no test at all. Researchers will track symptoms, activity, and…

This study looks at how changes in brain blood flow affect breathing control during sleep in healthy adults. Researchers will expose participants to normal oxygen and low oxygen levels to see how the brain responds. The goal is to better understand sleep apnea and related conditi…

This study looks at how sleep apnea changes pressure in the brain and belly during sleep in people with normal-pressure hydrocephalus. Researchers want to see if these pressure changes affect how well a surgically placed shunt (a tube that drains fluid from the brain) works. The …

This study will follow 1,000 adults in Spain who are suspected of having obstructive sleep apnea (OSA) and daytime sleepiness. Participants will undergo standard sleep tests, blood pressure monitoring, and fill out questionnaires about their quality of life and sleepiness. Resear…

This study follows 35 people with severe obesity who are having mini-gastric bypass surgery. Researchers want to see how the surgery changes body composition and improves related health issues like type 2 diabetes, sleep apnea, high blood pressure, and fatty liver disease. The go…

This study compares two ways of adjusting a nerve stimulator implant (Inspire system) for obstructive sleep apnea. Currently, patients need an overnight sleep study to fine-tune the device. Researchers want to see if a daytime sleep study works just as well. The trial will enroll…
