Recruiting studies
- NCT04974593RecruitingPhase 3
Test breath testing to guide a lactose-free diet in IBS
This trial studies whether a breath test (hydrogen/methane lactose testing) can predict who with IBS will improve on a lactose-free diet. If you have moderate-to-severe IBS and regularly eat lactose-containing foods, the test result may help tailor your diet approach.
Jette, Brussels CapitalAges 18–75 - NCT05347875Recruiting
App training to improve walking aid skills
This trial tests an app-based program meant to help people who already use walking aids learn and practice safer walking aid skills. It may help you move more comfortably if you can use the app and communicate with the study team.
Calgary, AlbertaAges 18–99 - NCT05336890Recruiting
Using past oxygen data to predict risks after premature birth
This study builds a personalized computer model that uses earlier breathing/oxygen information from preterm infants to predict possible health or development outcomes by preschool age. It may help families and doctors better estimate risks and plan support, using information already collected in a previous study.
Chicago, IllinoisAges 7 months–6.9 years - NCT05322785Enrolling by invitation
Breathing sample study to improve exhaled biomarker testing
This study works on better ways to collect and analyze substances from your breath. It may help researchers test how well these “breath markers” reflect lung or whole-body inflammation.
Indianapolis, IndianaAges 4–110 - NCT05226247Recruiting
Check whether careful weaning prevents lung fluid buildup
This study looks at people on a breathing machine for more than 48 hours who are starting a “spontaneous breathing trial,” a test used to see if they can breathe on their own. It focuses on those at higher risk of “weaning-induced pulmonary edema,” meaning fluid can collect in the lungs during the weaning process.
DijonAges 18 years+ - NCT05178056Recruiting
Spinal cord stimulator to improve breathing after spinal injury
This study looks at whether a spinal cord stimulator can improve breathing and lung function in adults with a certain type of spinal cord injury. It may help people who have ongoing breathing weakness after their injury.
Louisville, KentuckyAges 18 years+ - NCT05051254Recruiting
Breathing muscle testing in children with breathing muscle weakness
This study looks at how hard it is for children to breathe and how their breathing muscles work, using specific breathing-related tests. It may help doctors better understand breathing problems and choose care more effectively.
ParisAges birth–17 years - NCT04984473Recruiting
Breathing muscle training during heart rehab
This study tests whether breathing muscle training, added to regular heart rehab, can improve how well people with heart failure do day-to-day. It also compares results with healthy volunteers who do not have certain health problems.
Rochester, MinnesotaAges 18 years+ - NCT04923958Recruiting
Testing new TB screening and diagnostic tests
This study tests rapid TB screening and lab-style diagnostic methods to see how well they find TB disease and TB that is resistant to rifampin (a key TB drug). It may help doctors diagnose TB faster and more accurately, especially in people at higher risk.
TbilisiAges 12 years+ - NCT04670640Recruiting
Study of brain and therapy factors in trauma-related dissociation
This study looks at how dissociation (feeling detached or unreal) works in people who have had trauma. It tests different “mechanistic” approaches to better understand the brain and how to help, and whether participation can reduce these symptoms.
Atlanta, GeorgiaAges 18–65 - NCT04429100Recruiting
Breath-hold MRI test to measure liver scar levels
This study tests an MRI technique that briefly holds your breath to measure how scarred your liver tissue is. It may help doctors better spot and track liver fibrosis (scarring).
Hong Kong, ShatinAges Any age - NCT01627301Recruiting
Study of stress-related body overactivity in people with PTSD
This study looks at how the body’s stress system works in veterans with PTSD compared with veterans without PTSD. You may be asked about blood pressure, lifestyle, and health conditions to see whether the study measures differences that could help future treatment.
Decatur, GeorgiaAges 18–65 - NCT04157361Recruiting
Non-invasive lung testing in asthma and cystic fibrosis
This trial studies how well a non-invasive lung test can show lung involvement in people with asthma (especially IgE-related asthma) and people with cystic fibrosis. You might benefit by getting extra lung assessments without invasive procedures.
OlomoucAges Any age - NCT04118387RecruitingPhase 4
Study of how to treat central sleep apnea in Veterans
This Phase 4 study looks at what’s going on in the body during central sleep apnea and uses that information to guide treatment. If you have central sleep apnea, this could help confirm or improve how treatment is chosen for you.
Detroit, MichiganAges 18 years+ - NCT04100486Enrolling by invitation
Testing a noninvasive device to measure your body signals
This study uses a noninvasive bioelectronic device to record your body’s automatic (involuntary) signals. The goal is to see how well the device can analyze these signals and how your body responds in a controlled setting.
Manhasset, New YorkAges 18–60 - NCT03755726Recruiting
Study of care for dangerously high blood pressure
This trial looks at a health-care plan for people with malignant hypertension (very high blood pressure causing emergency eye and organ damage). It may help doctors better organize treatment and follow-up after this high-risk diagnosis.
AnnecyAges 18 years+ - NCT03505216Recruiting
Child lung symptom clinic registry for Swiss families
This study collects information from children and teens (up to age 16) who are seen in a children’s lung clinic for breathing or respiratory problems in Switzerland. The goal is to better understand these conditions in everyday care, which may help improve future diagnosis and treatment.
ViennaAges birth–16 years - NCT02323945Recruiting
Low-oxygen breathing to improve leg movement after spinal injury
This study tests whether breathing brief, mild low-oxygen air (under supervision) can improve leg mobility in people with a certain type of spinal cord injury. It may help with regaining movement, especially if you can already move your legs voluntarily but still have mobility limits.
Cambridge, MassachusettsAges 18–75

Common questions
- Are there clinical trials for breathing?
- Yes. Clin2 currently lists 354 recruiting breathing 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 breathing 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 breathing 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.
