Active clinical trials for "Sleep Apnea, Obstructive"

The objective of this study is to assess the long-term safety of the Genio® system in adult OSA patients with and without complete concentric collapse of the soft palate who have successfully been implanted with the Genio IS in a Nyxoah sponsored Clinical Investigation. (Serious) Adverse Device Effects and Device Deficiencies in subjects previously implanted with a Nyxoah Genio implantable stimulator (IS) and having the IS still in-situ (with therapy activated or deactivated) will be collected. The main question it aims to answer is: what is the long term safety profile of the Genio System? Participants will be asked to refer back to the site per standard of care and report on any (Serious) Adverse Device Effects and Device Deficiencies that may have occurred.

In this study, we aim to determine whether combined tolterodine and CPAP therapy is a more effective treatment for patients with OSAS than CPAP treatment only.

It was aimed to investigate the effect of expiratory muscle strength training (EMST) applied at different intensities on systemic inflammation and oxidative stress in patients with moderate obstructive sleep apnea syndrome (OSAS). In the study, 32 male patients diagnosed with moderate OSAS will be included in the study. Participants will then be divided into 2 groups by block randomization. In the three-blind planned study; the first group will receive high-intensity %60 maximum expiratory pressure (MEP) EMST training, and the second group will be given low-intensity 30% of MEP, EMST training for 12 weeks. Disease-related symptoms, disease severity apnea-hypopnea index (AHI), oxidative stress index (OSI) and systemic inflammation level, exercise capacity, respiratory muscle strength, sleep quality, daytime sleepiness, and fatigue severity will be evaluated before and after the study.

This trial is a 12 week, randomized, double-blind, placebo controlled, multicenter, 5-arm parallel group study of safety and efficacy of JZP-110 in the treatment of excessive sleepiness in adult subjects with OSA.

Patients who have obstructive sleep apnea (OSA) frequently stop breathing while they sleep. They often develop high blood pressure. We are not sure what drug is best to treat the high blood pressure. This study will give the patients guanfacine or hydrochlorothiazide (HCTZ) for 6 weeks after 2 weeks of placebo. The blood pressure response will be evaluated by 24 hour monitoring.

Background: Patients with obstructive sleep apnea run an increased risk of cardiovascular disease including hypertension. Continuous positive airway pressure (CPAP) is the first line of treatment. However, many patients skip CPAP for some nights. Aims: The primary aim was to investigate the cardiovascular effects of short-term CPAP withdrawal for five nights because of obstructive sleep apnea. Design: Randomized, parallel controlled trial Inclusion criteria: 100 patients with successful CPAP treatment for moderate to severe obstructive sleep apnea. Exclusion criteria: Dementia, heart infarction within 3 months, apnea hypopnea index > 10 with CPAP treatment. Randomization: 50 patients are randomized to sleep 5 days without CPAP and 50 patients to continue with CPAP treatment during the trial. Primary outcomes: Arterial stiffness, 24-hour blood pressure. Secondary outcomes: Effects of gender on outcome. Effects on brain natriuretic peptide, apnea-hypopnea index, oxygen desaturation-index, urine-catecholamines, blood lipids, C-reactive protein, glucose metabolism (S-glc, HBA1c), insulin resistance, serum creatinine, hemoglobin, daytime sleepiness (ESS, KSS), lung function (FVC, FEV1), airway inflammation (exhaled NO) Procedures: Sleep apnea investigation while patients are treated with CPAP for one night. Urinary samplings during the same night. They are also investigated with 24 h blood pressure measurements. Blood samples are taking fasting in the morning followed by measuring the arterial stiffness (Vicorder, Skidmore Medical UK) including pulse wave analysis using sphygmomanometer (Omron Japan). The same investigations are done at follow-up 5 days later where half of the patients have continued using CPAP treatment and half of them has slept without CPAP.

Obstructive sleep apnea (OSA) affects up to 1% of the general pediatric population and is associated with adverse behavior and quality of life, as well as long term cardiopulmonary system complications. Trisomy 21 (Down Syndrome) is the most common chromosomal disorder, with a incidence of approximately 1 per 660-800 births. Patients with Down Syndrome have a higher incidence of OSA than the general pediatric population, with rates of 30-60%, resulting in increased morbidity and decreased quality of life for affected individuals. In children, adenotonsillectomy (T&A) is often a contributing factor to OSA, and adenotonsillectomy is a first line treatment. Children with Down Syndrome often undergo T&A for obstructive sleep apnea, however 30-50% will have persistent obstructive sleep patterns requiring continuous positive pressure airway support (CPAP) or tracheotomy. Persistent obstruction is attributed to anatomic and physiologic differences in this population, including reduced muscular tone, macroglossia, maxillary hypoplasia, and lingual tonsil hypertrophy. This pilot study is designed to determine if the Inspire® Upper Airway Simulation System, Model 3024 IPG, and any subsequent iteration thereof that are approved under P130008 for the treatment of obstructive sleep apnea, which has already been approved for use in adults with OSA, can be safely implanted and used in adolescents and young adults with Down Syndrome.

The purpose of this study is to obtain additional safety and efficacy data on the use of Inspire® therapy for the treatment of subjects with moderate to severe Obstructive Sleep Apnea.

Obstructive Sleep Apnea (OSA) is a common condition that may induce hemodynamic and metabolic dysregulation. However, it is not clear if OSA is a mere epiphenomenon or contributes to increase the morbidity associated with metabolic syndrome. This study was designed to evaluate the impact of OSA treatment with CPAP in consecutive patients with metabolic syndrome.

The purpose of this study is to assess the safety and effectiveness of TranQuillTM Sling (a suture or thread used in surgery that is knotless) in snoreplasty (surgery procedure) for the treatment of snoring and mild OSA in adult subjects. The TranQuill Sling Snoreplasty (QSS) is a procedure where the suture will be inserted into the soft palate tissues for the treatment of snoring and/or mild obstructive sleep apnea. Soft palate tissues are tissues in the back of the roof of the mouth. The research results will be used to provide data on feasibility (strengths and weaknesses), safety, performance, and effectiveness data for the Surgical Specialties, Inc as a therapy for snoring and/or mild obstructive sleep apnea. The TranQuillTM Sling is approved by the U.S. Food and Drug Administration (FDA). The TranQuillTM Sling is used in all types of surgery that involved deep tissues in the body. The investigator in charge of the study is Dr. Boyd Gillespie. MUSC and Dr. Gillespie receive financial support from Surgical Specialties, Inc. to conduct the study. MUSC is the only place that this study will be conducted. For this research study the investigators plan to enroll a total of up to 20 subjects at the Medical University of South Carolina.
