Active clinical trials for "Sleep Apnea Syndromes"

Continuous Positive Airway Pressure (CPAP) is the reference treatment of patients suffering from Obstructive Sleep Apnea Syndrome (OSAS).This device functions as a pneumatic stent that stabilizes the upper airway, prevents periodic collapses during sleep.The correction of abnormal respiratory events during sleep allows improvement of symptoms related to OSAS and restores quality of life.The purpose of this study is to validate the efficacy of a new CPAP brand developed by Sleepinnov©.

This is a randomized, 4-period, placebo-controlled, crossover, phase 2 clinical study to examine the efficacy and safety of AD109 versus its individual components or placebo in patients with obstructive sleep apnea.

The purpose of the study is to see if metformin improves metabolism in patients with obstructive sleep apnea (OSA) using positive airway pressure (PAP) therapy. Metformin is approved by the Food and Drug Administration (FDA) for the treatment and prevention of diabetes. It is not approved for use in patients with OSA.

Overnight rostral fluid shift is one of the contributing factors for worsening obstructive sleep apnoea (OSA). Fluid shift has been recognized to play a role in the pathophysiology of sleep apnoea. Previous studies shown that fluid from the leg redistributes to the neck at night increases the neck circumference, hence indicating fluid accumulation in the neck. OSA patients are more susceptible to developing upper airway narrowing in response to fluid shift from the leg to the head and neck region. Previous studies were mainly done on Caucasian patients. The pathophysiology of OSA in Caucasian patients and Asian patients are different but both suffer a similar degree of OSA. The investigators would like to investigate if reducing leg swelling by a simple non-invasive intervention of wearing compression stocking during the day can attenuate sleep apnoea, and whether compression stocking is generally acceptable and well-tolerated among the general OSA population in Asia.

In general, central sleep apnea is not as common as obstructive sleep apnea but it is common in patients with heart failure. It has been repeatedly shown that central sleep apnea worsens the prognosis of heart failure. The current concept in the development of CSA is hypocapnia which causes temporary cessation of respiratory neural output. Different methods for supplement of CO2 have been used to eliminate CSA. However, variation of CO2 concentration during overnight treatment and tight-fitting mask made the treatment uncomfortable. It is important to develop a device with a comfortable mask to supply constant low dose CO2 without breathing difficulty. We recently developed a device for treatment of CSA.

The Obstructive Sleep Apnea is characterized by obstruction of the upper airway during sleep (for at least 10 sec), with repeated breathing pauses, accompanied by oxygen desaturation in the blood and by sleep interruption with repeated arousals. The investigators hypothesized that good sleep hygiene, the execution of respiratory rehabilitation exercises, with specific myofascial exercises on the muscles that are compromised in the Obstructive Sleep Apnea, can improve the patient's clinical outcome and quality of life. The objective of this study is to evaluate the effect of respiratory rehabilitation with myo-functional exercises in mild obstructive sleep.

The effect of expiratory muscle strength training (EMST) on sleep quality, disease severity, and respiratory muscle strength has been previously investigated in OSA syndrom. Only the effects of the high-intensity short-term EMST study in moderate OSAS patients were studied. High intensity and low intensity EMST has advantages and disadvantages.The study aims to compare the effects of high (60% MEP) and low (30% MEP) expiratory muscle strength training (EMST) on disease severity, sleep efficiency, snoring, fatigue severity and quality of life in severe OSAS patients.

The purpose of this study is to evaluate the safety and effectiveness of the SleepFlex program for treatment of mild to moderate OSA

Researchers are looking for a better way to treat people with obstructive sleep apnea (OSA). In people with OSA, the upper airways can narrow or close repetitively while sleeping. These breathing interruptions lead to reduction of oxygen in the blood or short arousals from sleep. Before a treatment can be approved for people to take, researchers do clinical trials to better understand its safety and how well it works. In this trial, the researchers want to learn more about how well BAY2586116 works in a small number of participants with OSA. The trial will include about 160 men and women who have OSA and are at least 18 years old. Women can only be included in this trial if they are not able to have children naturally. In this trial, the participants will take BAY2586116 and a placebo. A placebo looks like a treatment but does not have any medicine in it. All of the participants will take BAY2586116 through a nasal spray. They will also take the placebo as a nasal spray. This will be a crossover trial. This means all the participants will take both trial treatments one after the other, but in a different order. The participants will take each treatment once a day for 7 days. The researchers will use a measurement called the apnea-hypopnea-index (AHI) to measure the severity of the participants' OSA. The researchers will then compare the participants' AHI scores when they take BAY2586116 and when they take the placebo. During study, the participants will visit their trial site 5 times. At these visits the doctors will take blood samples, do physical examinations and check the participants' heart health using an electrocardiogram (ECG). They will also ask the participants questions about how they are feeling and if they have any medical problems. At 3 of the visits, the participants will stay at the trial site overnight. At these visits, the doctors will calculate the number of times the participants stop breathing per hour of sleep. After treatment, the participants will have a final visit 7 days later so the doctors can check their health.

Children with hypotonic upper airway obstruction have a high prevalence of severe obstructive sleep apnea, which if not treated has significant clinical consequence. Available treatment approaches, such as surgery and positive airway pressure, show limited efficacy and adherence. The multidisciplinary team has developed and now proposes to further test a non-surgical, well-tolerated nasopharyngeal airway device that in initial patients has resolved even extremely severe obstructive sleep apnea, and improved patient and family quality of life.
