Newest OSA - Obstructive Sleep Apnea clinical trials

All recruiting trials (13)

• How surgery for obstructive sleep apnea affects swallowing and oral function

  This study compares swallowing and oral function before and after surgical treatment for OSA versus non-surgical care in adults with moderate-to-severe OSA.

  Recruiting National Sun Yat-sen University · Kaohsiung City · NCT07880067

• PMOS and Sleep Apnea: A Pilot Look at Mitochondrial Function

  In women with PMOS, this pilot study tests whether sleep apnea treatment with CPAP improves mitochondrial function in leg muscle tissue.

  Recruiting University of Chicago · Chicago, Illinois · NCT07871149

• Once-weekly XW003 injections for people with obesity and obstructive sleep apnea on PAP therapy

  This trial will test whether once-weekly XW003 (ecnoglutide) injections help people with obesity and moderate-to-severe obstructive sleep apnea who are already using positive airway pressure therapy.

  Recruiting Phase 3 Hangzhou Sciwind Biosciences Co., Ltd. · Shanghai, Shanghai Municipality · NCT07434050

• Weekly XW003 injections for people with obesity and obstructive sleep apnea not using PAP

  This will see if once-weekly XW003 injections help adults with obesity and moderate-to-severe obstructive sleep apnea who are not using positive airway pressure (PAP) therapy.

  Recruiting Phase 3 Hangzhou Sciwind Biosciences Co., Ltd. · Beijing, Beijing Municipality · NCT07387094

• CPAP pressure equations versus sleep‑lab manual titration in Thai adults with obstructive sleep apnea

  This project will test whether CPAP predictive equations can match in‑lab manual titration for finding the right CPAP pressure in Thai adults with suspected obstructive sleep apnea.

  Recruiting at 2 sites Thammasat University · Pathum Thani and 1 other locations · NCT07376343

• How obstructive sleep apnea affects thinking and memory

  This project will try to see how thinking, memory, brain scans, and blood markers change over time in adults 18–65 newly diagnosed with obstructive sleep apnea who have no other chronic illnesses, and will follow a subgroup who start positive airway pressure therapy.

  Recruiting Comenius University · Bratislava · NCT07364318

• Effect of pulmonary vein isolation on sleep breathing in people with paroxysmal atrial fibrillation

  This study will test whether pulmonary vein isolation (a common AF ablation) changes sleep breathing measurements in people with paroxysmal atrial fibrillation who have risk factors for sleep apnea.

  Recruiting Primula Clinics · Grodzisk Mazowiecki · NCT07259200

• Treating obstructive sleep apnoea in people with difficult-to-control asthma

  We will see if treating obstructive sleep apnoea with CPAP helps adults with difficult-to-control asthma improve their symptoms, asthma control, and quality of life.

  Recruiting St. James's Hospital, Ireland · Dublin, Dublin · NCT07160868

• Endoscopic sleeve gastroplasty plus lifestyle changes versus lifestyle changes alone for people with obesity and obstructive sleep apnea

  This trial tests whether adding endoscopic sleeve gastroplasty (a non-surgical stomach-reducing procedure) to healthy eating and exercise helps adults with obesity and moderate-to-severe obstructive sleep apnea lose more weight and improve breathing during sleep.

  Recruiting Asian Institute of Gastroenterology, India · Hyderabad, Telangana · NCT07082608

• Oral NSAIDs plus paracetamol versus local dexamethasone infiltration for post-tonsillectomy pain in children

  This test will see if children aged 4–10 have less pain after tonsillectomy when given oral NSAIDs with paracetamol versus when dexamethasone is injected into the tonsil beds.

  Recruiting Ain Shams University · Cairo · NCT07035314

• Effects of Eszopiclone and Lemborexant in People with OSA and Low Arousal Threshold

  Aimed at people with obstructive sleep apnea who wake up too easily and have trouble staying or falling asleep, this study tests whether eszopiclone or lemborexant can help improve sleep when CPAP alone isn’t ideal.

  Recruiting Phase 2 Flinders University · Bedford Park, South Australia · NCT06928766

• Intensive CPAP therapy for stroke patients with sleep apnea

  This study is testing if extra support for using CPAP therapy can help stroke patients with sleep apnea recover better than standard care.

  Recruiting at 2 sites University of Washington · Downey, California and 1 other locations · NCT06722755

• Digital model for early diagnosis and monitoring of obstructive sleep apnea

  This study is testing a new digital approach to help diagnose and monitor people with obstructive sleep apnea to see if it can improve their treatment and understanding of related cognitive issues.

  Recruiting IRCCS San Raffaele · Milan, Italy · NCT06677580
