Active clinical trials for "Sleep Apnea, Obstructive"

This study compare the efficacy of high flow nasal cannula with nasal continuous positive airway pressure. All of participants will be randomized to receive one night high flow nasal cannula therapy and another night for nasal continuous positive airway pressure.

Improvement in CPAP adherence can be obtained by usingTelemonitoring. T4P® is a telemonitoring unit added on CPAP device allowing to obtain a daily report of usage duration, mask leaks, pressure and apnea-hypopnea index. The purpose of this study is to assess the impact of telemonitoring on the delay to the first technical intervention after CPAP titration night in CPAP-treated obstructive sleep apnea patients managed in the sleep unit. The shortening of this delay could help to improve adherence during the first weeks of treatment. As a secondary aim, the investigators would like to assess the impact of telemonitoring on mean adherence during the first 3 months of treatment, which is a crucial period.

Phase 1:The study is to evaluate the product reliability, therapy effectiveness and user feedback of a Continuous Positive Airway Pressure (CPAP) device in-home for up to 6 months. Phase 2: To evaluate the CPAP device with communication functionality with data upload.

This is a small pilot study that will compare High Flow Nasal Cannula (HFNC) therapy to oxygen nasal cannula therapy on infants who have obstructive sleep apnea (OSA) and are scheduled for a clinically ordered sleep study called polysomnography (PSG). The HFNC procedure uses humidified room air delivered by nasal cannula at higher pressures and will test if HFNC can control OSA in infants better or as well as low flow nasal oxygen, the current clinical standard of care. All the infants in the study will have a brief test period of about 3 to 4 hours with the HFNC before participants begin their standard clinical PSG for titration of oxygen by nasal cannula for treatment of OSA.

The purpose of this study is to determine if a lifestyle change program for obese patients who are already receiving continuous positive airway pressure (CPAP) treatment can achieve weight loss and overall improvement of obstructive sleep apnea syndrome (OSAS).

In this protocol the investigators will test the effect of dalfampridine (a potassium channel blocker) on genioglossus muscle activity (EMG GG) during wakefulness and sleep in healthy control subjects.

The investigators hypothesis is that obstructive sleep apnea (OSA) patients with a low arousal threshold may wake up too early during a respiratory event, before upper airway muscles can be activated to achieve stable ventilation. Thus, strategies to manipulate the respiratory arousal threshold could potentially improve the quality of sleep and sleep disordered breathing. Agents that raise arousal threshold are therefore likely to benefit some patients with OSA. The overall goal of this project is to determine the importance of the arousal threshold in OSA, determine which patients might benefit from a raised arousal threshold, and test this hypothesis by using pharmacological manipulation of the arousal threshold to achieve this goal.

Test the effect of added a single-use Varnum mouthpiece on pharyngeal collapsibility and obstructive sleep apnea (OSA) severity in patients who identify themselves as mouth breathers. Research indicates that nasal breathing not only may improve sleep apnea but it also increases circulation, blood oxygen, and carbon dioxide levels, slows the breathing rate, and improves overall lung volumes. Thus, the investigators will test whether a single-use Varnum mouthpiece can improve pharyngeal collapsibility and OSA severity in mouth breathers.

The researchers in this study want to learn how drug BAY2586116 works in patients with obstructive sleep apnea (OSA). OSA is a sleep disorder marked by breathing pauses during sleep due to repetitive obstructions of the upper airway. BAY2586116 is a new drug under development for the treatment of OSA. It blocks protein channels expressed on the surface of the upper airways in small mechanoreceptors (a type of molecule that sense and pass stimulus outside a cell on to the inside of the cell through mechanical gate on the surface of the cell). Thus, the negative pressure reflex alerting the brain of inspiration is triggered more easily leading to a stronger activation of throat muscles. This prevents narrowing or collapse of the upper airways during sleep which is one of the pathological key factors in OSA. Researchers will study the effects of different routes of administration (drops into the nose, spray into the nose or throat or spray into the throat by endoscopy). Endoscopy allows the doctor to look at areas in the throat that cannot be seen with a mirror: a thin tube-like instrument is inserted through the nose to check and give the medication. Different doses of the test drug will be given. They also want to find out if participants experience any medical problems during the study. Patients participating in this study will undergo three study parts. After completing Part A and Part B, participants will be asked to join Part C. In Part A, participants will receive both the test drug and placebo (a placebo looks like the test drug but does not have any medicine in it); in Part B, participants will receive the test drug twice via different routes of administration (drops in nose and spray in nose or throat) and in Part C, the participants would receive the test drug once via spray in throat by endoscopy. The sleep of the participants will be monitored by medical equipment. Participants will be asked to visit the clinic 7 times in 14 weeks in total.

This is a randomized, 3-period, placebo-controlled, crossover study to examine the efficacy and safety of AD182 and AD504 versus placebo in patients with obstructive sleep apnea.
