Effect of Added Varnum Mouthpiece on Pharyngeal Collapsibility and Sleep Apnea Severity in Mouth...
Obstructive Sleep ApneaTest 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.

Study on the Safety of Drug BAY2586116 and How it Works in Patients With Obstructive Sleep Apnea...
Sleep ApneaObstructiveThe 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.

Crossover Trial of AD182 and AD504 in Obstructive Sleep Apnea
Obstructive Sleep ApneaThis 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.

AD109 Dose Finding in Mild to Moderate OSA
Obstructive Sleep ApneaThis is a randomized, 3-period, placebo-controlled, crossover, phase 2 clinical study to examine the efficacy and safety of 2 doses of AD109 vs placebo in patients with mild obstructive sleep apnea.

Transcutaneous Electrical Stimulation in Obstructive Sleep Apnea
Obstructive Sleep ApneaThe aim of this study is to assess the efficacy of transcutaneous electrical stimulation of the upper airway muscles in patients with obstructive sleep apnea.

Acceptable Pressure Range for Continuous Positive Airway Pressure(CPAP) Treatment
Obstructive Sleep Apnea of AdultCompliance of continuous positive airway pressure (CPAP) derived from auto-titration is similar to that derived from manual titration, although pressure derived from the former was usually 2-5 cmH2O higher than the latter. Therefore the Investigators hypothesize that accurate titration maybe not necessary for successful treatment of obstructive sleep apnea (OSA) as long as CPAP pressure was not lower than the minimal effective pressure.

Comparison of Two Techniques of Combination Therapy for Treatment of Obstructive Sleep Apnea (OSA)...
Treatment for Obstructive Sleep ApneaTo study the effects of two combination therapies for patients with obstructive sleep apnea (OSA) who have been both intolerant to Positive Airway Pressure (PAP) therapy and sub-therapeutic to oral appliance therapy. Hypothesis 1. There is a difference between Continuous Positive Airway Pressure (CPAP) vs CPAP/Oral Appliance (OA) connect vs CPAP/OA disconnected in terms of: Apnea Hypopnea Index (AHI) reduction Amount of side effects Amount of Leaks Hours of use (compliance) CPAP pressure 2. There is a difference between connected and disconnected for the following symptoms: Epworth sleepiness Scale (ESS) Functional Outcomes of Sleep Questionnaire (FOSQ) Side effects Study Design - randomized prospective parallel

Safety, and Tolerability of the ZENS Device (PLUTO)
SnoringObstructive Sleep ApneaThe primary objective of the PLUTO study is to evaluate the safety and tolerability of the ZENS transcutaneous nerve stimulator device in primary snorers and those with mild obstructive sleep apnea. The study will assess the impact of ZENS on snoring frequency, duration, and other relevant sleep parameters. The intended purpose of the investigational device is to deliver a transcutaneous electrical stimulation signal to the hypoglossal nerve in the "ON" phase in order to alter the apnea hypopnea index (AHI), as well as mean snoring burden (intensity, duration), and to deliver no signal in the "OFF" phase of the study as a means for comparison. Subjects utilizing the ZENS Device will experience a reduction in snoring during the "ON" versus "OFF" phase, as quantified by a reduction in the percentage of time per hour of snoring (≥40 dB) in the active ZENS Device ("ON" phase) versus the inactive ZENS Device ("OFF" phase).
