DReAMzz- Dronabinol and Acetazolamide Medication for Sleep Apnea (ZZ). Dose Confirmation Crossover Study for IHL-42X in Subjects With Obstructive Sleep Apnea.

The goal of this randomized, double-blind, multi-dose crossover clinical trial is to determine the safety and efficacy of IHL-42X in subjects with obstructive sleep apnea. The primary endpoint is: Change in AHI4 at the end of each treatment period compared to baseline (each treatment period is 28 days). The study will consist of three separate four-way crossover dose-comparison studies each comparing three dose strengths of IHL-42X to placebo. The double-blind four-way crossover will be conducted according to a Williams design. Each of the crossover studies will test different doses of dronabinol in combination with a distinct, set dose of acetazolamide. In total, nine different combinations of dronabinol and acetazolamide formulated as IHL-42X will be tested in the study. The optimal dose strength will be selected based on safety and efficacy over a 4-week treatment period.

Study on the Management of COMISA

COMISA, the combination of obstructive sleep apnea (OSA) and insomnia, is a frequent and burdensome condition. Many patients with OSA experience clinically significant insomnia symptoms, and a substantial proportion of individuals with chronic insomnia also meet criteria for OSA. This comorbidity is associated with more severe symptoms, more complex diagnostic pathways, and reduced adherence to continuous positive airway pressure (CPAP) therapy. This study aims to better understand COMISA and evaluate whether adding daridorexant to CPAP treatment can improve treatment adherence and overall patient outcomes.

Patient-Perceived Symptoms at the Center of Obstructive Sleep Apnea (OSA) Management: Validation of the French Version of the Patient-Reported Apnea Questionnaire (PRAQ)

Obstructive sleep apnea (OSA) is a common and disabling sleep disorder in which the assessment and monitoring of symptoms are central to patient management. However, these steps require a shared understanding of the disease's clinical manifestations among patients, caregivers, and healthcare professionals in order to establish common therapeutic goals and meaningful clinical outcomes. Improving symptoms as experienced and reported by patients has become a major public health priority at both the national and international levels. In France, this patient-centered approach has been identified as a strategic priority by the French National Authority for Health (Haute Autorité de Santé, HAS) in its 2019-2024 strategic plan. Its implementation has been supported through the development and use of Patient-Reported Outcome Measures (PROMs). A disease-specific PROM for OSA, the Patient-Reported Apnea Questionnaire (PRAQ), has recently been developed and validated. The primary objective of this study is to validate a French version of the PRAQ. Secondary objectives are to evaluate the relationship between PRAQ scores and subjective sleep parameters, and to develop a shortened version of the questionnaire to facilitate its use in both clinical practice and research.

A Comparative Effectiveness Study of Positive Airway Pressure (PAP) Therapy, Dental Device, and Atomoxetine-Oxybutynin for Treatment of Obstructive Sleep Apnea in Adults

Researchers want to identify which treatments for obstructive sleep apnea (OSA) work best and are easiest for patients to use consistently. Eligible participants will be randomly assigned one of three OSA treatments: traditional PAP therapy, a dental device, or a combination of two FDA-approved medications (atomoxetine and oxybutynin) that are currently approved for other conditions. Over the course of one year, participants will attend two in-person visits and take part in four phone check-ins to complete surveys, report any side effects, and discuss how well they are following their assigned treatment.

Endotype DIrected Treatment for OSA in Down Syndrome

Down syndrome is the most common genetic cause of intellectual disability. People with Down syndrome often have obstructive sleep apnea (OSA), a condition where people have difficulties with breathing while asleep. OSA can lead to poor sleep, worse quality of life, behavior problems and more difficulties with thinking ("cognitive impairment"). Current treatments for OSA in people with Down syndrome are not very effective or require surgery. The combination of 2 medications, atomoxetine and oxybutynin ("ato-oxy") is a promising treatment for OSA in people with Down syndrome, but ato-oxy does not work for everyone with Down syndrome. Similarly, oxygen is effective for OSA in some people, but does not work for everyone. This study will evaluate the use a precision medicine approach to increase the effectiveness of OSA treatment in people with Down syndrome. The study will compare two groups. In the first group, everyone will be treated with ato-oxy. In the second group, a precision medicine approach will be used to assign participants to either ato-oxy or oxygen therapy, based on the specific reasons they have OSA. The research team will enroll 200 children (age 6-17 years old) and adults with Down syndrome and OSA from five sites across the country. Half of participants will randomly receive ato-oxy while the other will receive either oxygen or ato-oxy dependent upon which treatment would be expected to work better for them. The research team will measure OSA severity, quality of life, behavior and cognition at the start of the study and after 12 months of treatment for every participant. The study will also track any treatment side effects for each treatment group.

Sleep Apnea Biomarkers and Adherence to Continuous Positive Airway Pressure

Obstructive sleep apnea (OSA) is commonly assessed using the apnea-hypopnea index, although this measure does not fully reflect cardiovascular risk or the physiological impact of the disease. Emerging biomarkers, including sleep apnea-specific hypoxic burden, pulse wave amplitude drop index, and heart rate response, may provide additional information on cardiovascular vulnerability. This prospective multicenter observational study will investigate the association between these biomarkers, measured from the diagnostic sleep study, and adherence to continuous positive airway pressure (CPAP) therapy after three months. Symptoms, quality of life, clinical characteristics, and changes in biomarkers under continuous positive airway pressure will also be evaluated.

Personalised Active Self-management of Sleep Apnea Program

This study is to assess the feasibility and acceptability of the PASS in patients with OSA. Second, the study examines its effectiveness in improving PAP uptake and adherence, self-efficacy in self-care, changes in health-related habits, and health outcomes. We also assess the facilitators and barriers to implementing the PASS. This is a two-group pilot randomized controlled trial (n=60) with a 4-month follow-up. Subjects assigned to the intervention group will receive a 4-month Personalized and Adaptive Sleep Support (PASS) program, a digital platform-based intervention. The 4-month program incorporates: i) a 20-minute brief motivational interviewing session; ii) a digital platform where users can view personalized OSA health-related videos and information, track their adherence to prescribed treatments, log their daily activities and dietary intake, and set personal health goals; and iii) continuous personalized chat-based messaging and phone call support. Participants in the control group will receive a 4-month general hygiene program, including (i) a 20-minute session, (ii) messaging, and (iii) phone call support. The feasibility and acceptability of the PASS will be evaluated via semi-structured interviews at the 4-month follow-up. Self-administered questionnaires will be used at baseline and 4 months, and objective assessment tools (such as sleep tests) will be used at baseline and at the 4-month follow-ups. PAP adherence data will be downloaded from PAP machines (if available) for all subjects in both groups at baseline and at month 4.

How Wall Squat Exercise Affects Blood Pressure in People With High Blood Pressure and Treated Sleep Apnea (WALLPRESS)

This study will look at whether a simple exercise called the isometric wall squat can help lower blood pressure in adults who have both hypertension and obstructive sleep apnoea treated with CPAP. Obstructive sleep apnoea is a condition in which breathing repeatedly stops or becomes shallow during sleep, and it is closely linked to high blood pressure. Although CPAP helps treat sleep apnoea, it usually lowers blood pressure only a little, so additional non-drug strategies may be useful. The study will compare two situations in the same participants: one session of wall squat exercise and one non-exercise control session. Each participant will take part in both sessions, but the order will be random. This design helps the researchers compare blood pressure changes more fairly within the same person. Participants will first attend a familiarization session, where the study procedures will be explained and the exercise intensity will be checked. After that, they will complete the two study sessions at home, during their usual CPAP treatment visits. The sessions will be separated by at least 48 hours and completed within one week. Both sessions will be scheduled at the same time of day to reduce the effect of normal daily changes in blood pressure. The main result the researchers will measure is the average systolic blood pressure during the 12 hours after each session, using ambulatory blood pressure monitoring. This means blood pressure will be measured over time while the participant goes about normal daily activities. The researchers want to find out whether a single session of wall squat exercise produces a greater blood pressure reduction than simply resting without exercise. This study may help improve understanding of whether isometric exercise can be a practical, low-cost, home-based option to support blood pressure control in people with hypertension and CPAP-treated obstructive sleep apnoea.

Identification of Biomarkers of Obstructive Sleep Apnea.

Obstructive sleep apnea (OSA) is a common sleep disorder associated with intermittent hypoxia, systemic inflammation, oxidative stress, and an increased risk of cardiovascular and metabolic diseases. Current diagnostic methods are effective but have limited availability and do not adequately predict disease burden or treatment response. The purpose of this study is to identify and validate blood biomarkers that may improve the screening, diagnosis, risk stratification, and monitoring of adults with OSA. A total of 120 participants will undergo clinical evaluation and overnight polysomnography. Participants with moderate-to-severe OSA will be randomly assigned to either immediate or delayed positive airway pressure (PAP) therapy, while participants without OSA will serve as controls. Blood samples will be collected at predefined time points and analyzed for inflammatory, metabolic, oxidative stress, and other candidate biomarkers. The study aims to determine which biomarkers are associated with OSA severity and how they change in response to PAP therapy. The results may contribute to the development of more accessible and personalized diagnostic and monitoring strategies for patients with OSA.

Effectiveness of Audio Cues to Achieve Positional Therapy in Patients With Positional Obstructive Sleep Apnea

Patients with obstructive sleep apnea (OSA) often experience more frequent and severe breathing disturbances when sleeping in the supine (back-sleeping) position compared with non-supine positions. Positional therapy aims to reduce time spent sleeping in the supine position, but existing treatment options may be limited by comfort and effectiveness. This study evaluates the effectiveness and usability of WhisperPT, an investigational in-ear positional therapy device that delivers gentle audio cues during sleep to encourage participants to move from the supine to a non-supine sleeping position. The study will assess the device's ability to reduce the apnea-hypopnea index (AHI), decrease time spent sleeping supine, and evaluate participant comfort and ease of use.

Empirical CPAP Therapy for Suspected Obstructive Sleep Apnea in a Resource-Limited Setting

Obstructive sleep apnea (OSA) is a condition where a person's airway repeatedly collapses during sleep, causing them to stop breathing briefly and disrupting their rest. The standard way to diagnose OSA is a formal overnight sleep study called polysomnography (PSG). However, in resource-limited settings, sleep study centers are scarce, which can lead to months of waiting before a patient can be diagnosed and treated. Delaying treatment can negatively affect a patient's quality of life and increase their risk for other health issues. The purpose of this observational study is to evaluate the clinical benefits of starting continuous positive airway pressure (CPAP) therapy early for patients who are highly suspected to have OSA, while they wait for their formal sleep study. Researchers will enroll adult patients who have symptoms of OSA (such as loud snoring, witnessed breathing pauses, and severe daytime sleepiness) and a high clinical probability of having the condition. Instead of waiting for the official sleep study to begin treatment, these participants will be provided with an Auto-CPAP machine set to a practical pressure range. The main goals of the study are to evaluate: * If this early, empirical Auto-CPAP treatment improves patients' daytime sleepiness and overall quality of life, which will be measured using specialized questionnaires. * How accurately the temporary Auto-CPAP machine's pressure settings match the final, optimal pressure settings that will eventually be determined by the formal sleep study.

Mandibular Advancement Device (MAD) and Continuous Positive Airway Pressure (CPAP) for Treatment of Adult Patients Diagnosed With Moderate Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is a frequent illness related to sleep and breathing with many symptoms and complications. The primary choices of treatment are continuous positive airway pressure (CPAP) and removable appliance for protruding the mandible when sleeping (MAD). Treatment with CPAP is superior to treatment with MAD but many patients don't tolerate CPAP why they seek treatment with MAD. In Denmark, treatment with MAD is not free of charge unlike treatment with CPAP and MAD is therefore not offered systematically to the patients. The same applies to adjustment, control and effect of the MAD treatment. MAD treatment has a positive effect on OSA in general but the effect varies due to differences in selection of patients and lack of specifying who performs and evaluates MAD treatment, the effect on sleep and possible side effects in muscles and the temporomandibular joint as well as the occlusion during treatment. It is therefore of great importance to investigate the effect of MAD treatment as well as short- and long-term side effects. The aim is therefore to compare the treatment effect of MAD and CPAP and how significant the investigation of the airways and the face is for the treatment effect and possible side effects. The project is a 4-year investigation and 70 adult patients diagnosed with moderate OSA are included. The results from the investigation will be of great importance for the choice of treatment and prognosis for the individual patient and socio-economic since the treatment of OSA could be tailored the individual patient and the treatment effect optimised.
