Sleep apnea syndrome

This UK trial tests a device that uses mild electrical pulses to keep the airway open during sleep in people with obstructive sleep apnoea. It is for adults who cannot use standard CPAP therapy. The study will compare the device to usual CPAP care over three months to see if it i…

This study compares two types of tonsil surgery for adults with obstructive sleep apnea and enlarged tonsils. One surgery removes the tonsils completely, while the other removes only part of them. The goal is to see if the less invasive approach works just as well at improving br…

This study tests whether a high-flow nasal cannula (HFNC) — a soft tube that delivers warm, humidified air through the nose — works as well as the standard CPAP mask for children with moderate-to-severe obstructive sleep apnea. About 258 children aged 2 to 18 will use one of the …

This study tests a new device called Elara APAP for people with obstructive sleep apnea. The device delivers air pressure to keep the airway open during sleep. About 55 adults who already use an APAP machine will have one night of sleep monitoring to see if the device reduces bre…

This study tests whether injecting botulinum toxin (like Botox) into a throat muscle can help people with moderate to severe obstructive sleep apnea. The goal is to reduce breathing pauses during sleep and improve oxygen levels and daytime sleepiness. The trial involves 20 adults…

Obstructive sleep apnea is common but often undiagnosed, and standard sleep tests can be slow to access. Researchers are studying Apneal Dx, a CE-marked smartphone app that uses the phone's sensors worn on the chest to record breathing during sleep. The study follows adults in fi…

This study tests whether a special pacifier, called CURAPROX, can reduce the severity of obstructive sleep apnea (OSA) in infants with Down syndrome. Fifty infants will be enrolled at one month old, with half using the pacifier and half not. At six months, sleep tests will measur…

Researchers are testing whether a monthly injection of berobenatide can reduce the severity of obstructive sleep apnea and lower body weight in adults who have overweight or obesity and use a PAP breathing machine. The trial enrolls about 258 adults with moderate to severe sleep …

This study looks at whether starting CPAP therapy early for people with suspected obstructive sleep apnea (OSA) can improve their daytime sleepiness and quality of life while they wait for a formal sleep study. Participants are adults with strong signs of OSA, such as loud snorin…

This study tests whether a decision-making tool can help veterans with sleep apnea choose and stick with a treatment that works for them. About 128 veterans will be randomly assigned to receive either a brief education program or the same program plus a personalized tool. The goa…

This study tests a small device called the Serene Sleep Palatal Implant, placed in the soft palate to reduce snoring and mild-to-moderate obstructive sleep apnea. About 26 adults will be split into two groups based on their condition. The main goal is to check safety, like whethe…

This study tests whether a newer 'splintless' jaw surgery is more accurate and safer than the standard method for treating obstructive sleep apnea. About 66 adults with moderate to severe sleep apnea who cannot use CPAP will be randomly assigned to one of the two surgeries. Resea…

This study tests a wearable smart eye-mask that combines gentle heat and massage with voice-guided sleep therapy to help people who have both insomnia and sleep apnea. The 4-year project will first explore how the condition works, then develop the device, and finally test it in 1…

This early study tests a neck device that uses gentle suction to keep the airway open during sleep, which might help people with obstructive sleep apnea. Ten healthy volunteers will wear the device during one night of sleep and compare their breathing to a night without it. The g…

This study tests whether a nerve block (injecting numbing medicine near the cheekbone) can control pain after tonsillectomy in children aged 3-9, reducing the need for opioids. Sixty kids having tonsil surgery for sleep apnea will be randomly assigned to get either the nerve bloc…

Researchers at a French sleep center are studying adults with obesity who are referred for a sleep study because of suspected obstructive sleep apnea. The team measures how much carbon dioxide builds up in the blood overnight using a skin sensor, then compares that cumulative exp…

This study looks at what happens when people who live above 2600 meters, in places like Quito, spend a week at sea level and then return to altitude. Researchers will measure sleep quality, oxygen levels during the night, and breathing patterns in healthy adults and in people wit…

Researchers are studying what happens when people with pulmonary arterial hypertension who live above 2600 meters spend a week at sea level. The trial compares their sleep, blood oxygen, and breathing during sleep at altitude and after seven days at sea level. It includes both pa…

This observational study investigates whether cardiac autonomic neuropathy (nerve damage affecting the heart) changes the risk of death and cardiovascular events in people who have diabetes, coronary heart disease, and sleep apnea. Researchers will follow 326 participants, dividi…

This study looks at how the size of the upper airway might influence teeth grinding (bruxism) during sleep in people with obstructive sleep apnea. Researchers will use safe, low-radiation 3D scans and sleep tests to measure airway volume and bruxism in 80 adults. The goal is to b…

This study follows 60 adults who had jaw surgery (maxillomandibular advancement) for obstructive sleep apnea. Some develop central or mixed sleep apneas after surgery, and researchers want to see if these breathing issues get better, stay the same, or get worse over a year. Parti…

This study follows 60 adults with pulmonary hypertension (high blood pressure in the lungs) for 2 years. Researchers will measure breathing problems during sleep and heart rate changes to see how they relate to the disease. No new treatment is given; participants continue their u…

This study will test three ways of giving oxygen to 280 adults during colonoscopy sedation: standard continuous flow, breath-synchronized pulses via the Sovant device, and CPAP. Researchers will track how often patients have breathing pauses or low oxygen levels. The goal is to f…

This study looks at the teeth, mouth, and face health of 25 people with Mowat-Wilson syndrome, a rare genetic condition. Researchers will check for cavities, gum disease, and facial features, and ask about quality of life. No treatment is given—the goal is to gather information t…

This study looks at whether a simple arm exercise test, called the 6-Minute Pegboard and Ring Test, can reliably measure upper body function in adults with obstructive sleep apnea. Researchers will compare test results with sleep study data and questionnaires. The goal is to impr…

This study will follow 1200 people who have had a heart attack or unstable angina and also have sleep apnea. Researchers will collect blood, urine, and stool samples to understand how sleep apnea affects metabolism and heart risk. The goal is to build an AI-based tool to better p…

This study will follow 11,100 adults with sleep-disordered breathing for up to 5 years. Researchers will collect health data and samples to find better ways to predict risks and tailor treatments. No new drug or device is being tested; participants receive standard care like CPAP…

This study looks at why people with heart failure or those taking opioid painkillers develop central sleep apnea (pauses in breathing during sleep). Current treatments don't work well, so researchers will test combinations of breathing machines and medications in 200 Veterans. Th…

This study will use an overnight sleep test (polysomnography) to measure breathing problems during sleep in 30 adults with systemic sclerosis (scleroderma). The goal is to find out how common sleep-disordered breathing is in this group. No treatment is given—this is purely an obs…

This study looks at whether treating obstructive sleep apnea with CPAP can change how certain immune cells (neutrophils) behave. Researchers will collect blood from 120 people — 80 with moderate-to-severe sleep apnea and 40 healthy controls — to measure immune cell activity and r…

This study will check how common it is for obese people with sleep apnea to still have low breathing at night even when using a CPAP machine. About 139 adults will wear a special skin sensor that measures oxygen and carbon dioxide levels overnight. The goal is to find out how man…
