Respiratory muscle training to help patients come off the ventilator
This trial studies whether exercises for breathing muscles can help people who are having a hard time coming off a breathing machine in the ICU. It may help you breathe with less ventilator support once your body is stable enough.
LeuvenAges 18 years+ - NCT04395937Recruiting
Study of gentle aerobic exercise to improve severe asthma control
This trial studies whether a lower-intensity aerobic exercise program (not maximal effort) can improve asthma symptoms and control. It is meant for adults with asthma who are still not well controlled despite current inhaler treatments.
Liège, LiegeAges 18–65 - NCT02924818Recruiting
Research study for adults with long-term breathing lung diseases
This study enrolls adults with chronic lung conditions like COPD, cystic fibrosis, bronchiectasis, or interstitial lung disease. It’s designed to learn more about these illnesses and to develop better ways to study or improve care.
ReimsAges 18 years+ - NCT05689034RecruitingPhase 2/Phase 3
Azvudine for early COVID-19 in higher-risk adults
This trial studies azvudine in adults with early COVID-19 symptoms to see if it can prevent the illness from getting severe. You may qualify if you’re within about 5 days of symptom start and have risk factors for worsening disease.
Beijing, Beijing MunicipalityAges 18–120 - NCT06212492Recruiting
Muscle relaxants and stomach positioning for ARDS
This trial tests whether combining two treatments—medications that relax muscles (neuromuscular blocking agents) and lying on your stomach (prone positioning)—can reduce lung damage in people with severe ARDS on a breathing machine.
MarseilleAges 18 years+ - NCT06477458Recruiting
AI analysis of CT scans for lung health before chest surgery
This study uses a computer program (deep learning) to analyze your chest CT scan and lung function test results before surgery. The goal is to see if the AI can help doctors better assess your lungs and plan your operation.
Guangzhou, GuangdongAges 18–75 - NCT03528525Recruiting
Study of breathing-related rare genetic diseases in Chinese children
This registry study collects and stores samples from children with breathing-related rare genetic (inherited) diseases to learn more over time. It may help researchers better understand these conditions and improve future care, especially through long-term follow-up.
Beijing, Beijing MunicipalityAges 1 month–18 years - NCT06369584Recruiting
Prone Position for Children on ECMO with Severe ARDS
This trial tests if lying face-down (prone position) helps children with severe ARDS who are already on ECMO, a machine that supports the heart and lungs. It aims to see if this position improves recovery.
Beijing, Beijing MunicipalityAges 1 month–18 years - NCT06401239Recruiting
Study on recovery from severe breathing problems
This study looks at how recovery goes for people who had severe breathing problems in the hospital. It involves talking with you and a partner who helps care for you, to learn how to improve support for both of you.
Baltimore, MarylandAges 18 years+ - NCT06123143Recruiting
Finding the best time to stop CPAP in very small babies
This study looks at when to safely take very small babies (born before 30 weeks) off breathing support called CPAP. It aims to find the ideal time to help their lungs grow stronger.
