Recruiting studies
- NCT06408220Recruiting
Stomach cancer risk check for minority groups
This study checks if you are at high risk for stomach cancer. You will give blood samples and have a stomach exam (endoscopy) to look for early signs.
Duarte, CaliforniaAges 40–80 - NCT06306963Recruiting
Stomach blood vessel condition and digestion symptoms study
This study looks at people with a stomach condition called gastric antral vascular ectasia (GAVE) to understand how it affects digestion and causes symptoms. Researchers want to learn if stomach muscle function problems are common in this condition.
Rochester, MinnesotaAges 19 years+ - NCT05973656Recruiting
Study how alcohol affects the risk of mouth cancer
This study looks at how a breakdown product from alcohol (acetaldehyde) may play a role in oral (mouth) cancer. It may help researchers understand who is more affected by alcohol and why.
Minneapolis, MinnesotaAges 18–45 - 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 - NCT07531771Recruiting
Breathing Exercises for Early-Stage COPD
This study tests whether two types of breathing exercises—pursed lip breathing (slowing your breath) and alternate nostril breathing—can improve lung function and quality of life in people with mild COPD. You'll learn and practice these techniques to see if they help you breathe better.
IslamabadAges 40–65 - NCT07253883Recruiting
New breathing device test for asthma and COPD
This trial is testing a new breathing device that may be as accurate as standard tests for diagnosing asthma and COPD. It could offer a simpler and quicker way to check your lung health.
Liverpool, MerseysideAges 18–110 - NCT05890911Enrolling by invitation
Studying dopamine pathways in breathing problems during sleep
This study looks at how dopamine-related brain pathways may be involved in sleep-related breathing problems. It may help researchers better understand what causes these conditions and how to evaluate them with sleep testing.
WroclawAges 18–80 - NCT06554353Recruiting
Breathing and exercise tests for shortness of breath
This study looks at how well two breathing tests work for people who have shortness of breath. You will do a breathing test and an exercise test to help doctors better understand your symptoms.
Rochester, New YorkAges 18 years+ - NCT04620343Recruiting
Study of breathing treatment for EILO during exercise
This trial tests a treatment approach for exercise-related breathing difficulty called EILO. It aims to help people whose breathing problems show up during peak exercise and who want ongoing follow-up.
Bergen, VestlandAges 12 years+ - NCT04022109Recruiting
Check gastric cancer using breath chemical signals
This study looks at chemical signals in your breath to help screen for or understand gastric (stomach) cancer. It may help doctors improve earlier detection, or better sort out who may need further tests.
São PauloAges 18 years+ - NCT07389993Recruiting
Breathing muscle study after childbirth
This study looks at how childbirth affects the diaphragm and other breathing muscles in women with and without a condition called diastasis recti abdominis (abdominal muscle separation). It aims to understand differences in breathing muscle function to help guide future treatments.
Pátrai, AchaiaAges 18–50 - NCT07003282Recruiting
Reducing secondhand smoke exposure in pregnancy
This study tests a program to help pregnant women and their partners reduce the baby's exposure to secondhand smoke. It may be a good fit if you are pregnant, don't smoke, and live with a partner who smokes.

Common questions
- Are there clinical trials for breath tests?
- Yes. Clin2 currently lists 36 recruiting breath tests 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 breath tests 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 breath tests 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.
