BronAges 4–17 - NCT07725471Recruiting
Comparing breathing and neck release in stroke recovery
This study compares two gentle therapy techniques—special breathing exercises and a hands-on release at the base of the skull—to see which helps stroke survivors with one-sided weakness regain movement and breathing. It may be a good fit if you're still recovering from a first stroke months ago and don't have major heart or lung problems.

Breath test to quickly detect infections in blood cancer patients
This study tests whether a quick breath test can detect infections early in people receiving intensive treatment for certain blood cancers or bone marrow transplant patients. If it works, it could help doctors find infections faster and adjust treatment sooner.
LeuvenAges 18 years+ - NCT03422302Recruiting
CPAP or breath-holding to reduce lung tumor motion
This study looks at whether using a CPAP breathing device or deep breath-holding can keep lung tumors from moving during targeted radiation. The goal is to improve safety and accuracy of stereotactic body radiation for lung cancer.
Houston, TexasAges 18 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+ - NCT04336579Recruiting
Breathing exercises during knee replacement care
This study tests whether practicing diaphragmatic (belly/chest-breathing) exercises during total knee replacement with a nerve pain catheter is helpful for comfort or recovery. You may qualify if you are having knee replacement and have the specific type of nerve catheter, and you’re willing to learn and follow the breathing routine.
Los Angeles, CaliforniaAges 50–90 - NCT04471506Recruiting
Breathing and walking program for hormonal and tumor markers
This study tests whether a combined program of interval aerobic training (alternate “hard/easy” exercise) and mindfulness breathing can improve hormone, metabolic (body chemistry/energy), and tumor marker measures in women after menopause. If you meet the criteria, you may benefit from structured activity and breathing techniques while researchers track health changes over time.
CairoAges 55–65 - NCT04971850Recruiting
Sleep study for children with possible breathing sleep problems
This trial looks at sleep-related breathing problems (“sleep-disordered breathing”) in children and young adults and how they may affect thinking and memory using sleep study testing plus neurocognitive (thinking) assessments. It may help doctors better understand symptoms and identify who could benefit from treatment.
ParisAges 1–20 - NCT05341726Recruiting
Test a program to improve asthma control in Black adults
This study tests an approach that combines education and support to help adults with uncontrolled asthma manage their symptoms better and use treatments correctly. It focuses on Black adults receiving care at specific community health clinics.
Beacon, New YorkAges 18 years+ - NCT05589753RecruitingPhase 1/Phase 2
Testing treatment for sleep breathing problems in people on opioids
This trial studies a treatment approach for sleep-disordered breathing (breathing problems during sleep) in Veterans who take prescription opioids. It may help doctors learn safer ways to manage sleep breathing issues that can be made worse by opioid use.
Detroit, MichiganAges 18–89 - NCT05727020Recruiting
Breath test study for pancreatic cancer and related conditions
This study checks whether breathing out certain chemicals (volatile organic compounds) can help identify pancreatic ductal adenocarcinoma (pancreatic cancer) or related pancreas problems. You may qualify if you’re an adult with suspected/confirmed pancreatic conditions and can safely take part in breath testing or surgery-related tissue collection.
LondonAges 18 years+ - NCT05844514Recruiting
Breath test study for colorectal cancer detection and risk
This study tests a breath analysis (a sample you give by breathing into a device) to help detect or better understand colorectal cancer. It may help researchers see whether breath results can identify cancer sooner and in people who haven’t started treatment yet.
LondonAges 18 years+ - NCT05908591Recruiting
Pregnancy sleep study on breathing, blood vessel function, and safety
This study looks at how sleep and breathing changes during pregnancy may affect blood vessel function and pregnancy safety. You may be asked about your sleep and possibly have health checks during the middle of pregnancy.
Edmonton, AlbertaAges 18 years+ - NCT05917262Recruiting
Mindfulness breathing vs heart-rate training after shoulder surgery pain
This trial compares two non-drug techniques—mindful breathing and heart-rate (HR) biofeedback—to see which helps reduce pain after shoulder surgery. You may be able to join if you have ongoing shoulder pain after surgery and haven’t been using these practices very often.
TaoyuanAges 18 years+ - NCT05976165Recruiting
Breath testing study for small bowel bacterial overgrowth
This study checks whether breath tests can help identify small intestinal bacterial overgrowth in people with reflux-like symptoms (heartburn or regurgitation). If you qualify, you may be asked to avoid certain medicines and treatments for a short time so the test results are accurate.

- 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.
