Ningbo, ZhejiangAges 18 years+ - NCT07225686RecruitingPhase 3
Maridebart Cafraglutide for sleep apnea in adults on CPAP
This study is testing whether a new medicine, called Maridebart Cafraglutide, can help people with obstructive sleep apnea who are already using a CPAP machine. The medicine may help with weight loss and potentially improve sleep apnea. Participants will either receive the medicine or a placebo (an inactive substance), and the study lasts for several months.
Northridge, CaliforniaAges 18–99 - NCT07434050RecruitingPhase 3
Study of XW003 for obesity with sleep apnea on CPAP therapy
This trial tests an investigational drug called XW003 to see if it helps people with obesity and obstructive sleep apnea who are already using a positive airway pressure (PAP) machine, like CPAP. It aims to improve weight loss and sleep apnea symptoms.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07226765RecruitingPhase 3
Weight-loss drug for sleep apnea without CPAP
This study tests a new weight-loss medication called maridebart cafraglutide against a placebo in people with moderate to severe obstructive sleep apnea who are not using a CPAP machine. The goal is to find out if weight loss can reduce symptoms like pauses in breathing during sleep.
Northridge, CaliforniaAges 18–99 - NCT07472738Recruiting
Studying treatable traits in chronic airway diseases
This trial is studying people with chronic lung conditions, like COPD or asthma, to find treatable traits. It also includes healthy volunteers for comparison, to better understand what makes these diseases different and how to personalize treatment.
Beijing, Beijing MunicipalityAges 20–75 - NCT04190953Recruiting
Braces and expanders in kids to improve airflow space
This study looks at how jaw and palate treatments affect airflow through the upper airway in children with a specific bite and jaw shape. It may help researchers understand which treatments improve space for breathing and related pressure changes.

Common questions
- Are there clinical trials for airway obstruction?
- Yes. Clin2 currently lists 93 recruiting airway obstruction studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a airway obstruction trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a airway obstruction trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
