Surgery versus rehabilitation for a torn ACL
This study compares two ways to treat a tear of the anterior cruciate ligament (ACL) near the top of the knee. It looks at whether having surgery is better than a non-surgical approach with physical therapy. You may be eligible if your tear is recent and you have no other knee injuries.

Exeter, DevonAges 25–80 - NCT06140901Recruiting
Study of children's airways after viral lung infections
This study looks at the airways of children aged 1 month to 6 years who had a serious lung infection with adenovirus or rhinovirus. Researchers want to understand how the infection affects the airways and why some children develop lasting breathing problems.
MarseilleAges 1 month–6 years - NCT06130449RecruitingEarly Phase 1
Testosterone for men with spinal cord injury
This study tests whether testosterone therapy can improve brain and nerve function in men with low testosterone who have had a spinal cord injury for more than a year. It involves three visits over 30 days and may help with thinking, mood, or other nerve-related issues.
The Bronx, New YorkAges 18–80 - NCT06117254Recruiting
Hearing aids for Veterans with trouble hearing in noise
This trial tests whether hearing aids help Veterans who have trouble hearing in noisy places but whose hearing loss is not severe. You'll visit the VA Portland Medical Center several times to see if the aids improve your daily life.
Portland, OregonAges 18–79 - NCT06127667Recruiting
Balance, brain health, and aging
This study looks at how your brain and blood vessels work together to keep you balanced as you age. It may help researchers understand why some people stay steady on their feet and others don't.
Minneapolis, MinnesotaAges 21–95 - NCT06122701Enrolling by invitation
Vitamin B1 movement in people with and without an active OCT1 transporter
This study checks how vitamin B1 (thiamin) moves through the body in healthy people. It compares two groups: those with a normal OCT1 liver transporter and those with a less active one. The goal is to see if genetics affect how your body handles vitamin B1.
Greifswald, Mecklenburg-VorpommernAges 18–50 - NCT06110403RecruitingPhase 1/Phase 2
Study of a long-acting inhaler for COPD symptoms and lung function
This trial tests a once-daily inhaler that combines a long-acting bronchodilator with a corticosteroid to see if it improves breathing, lung function, and quality of life in people with moderate-to-severe COPD who have significant shortness of breath.
LilleAges 40–75 - NCT00230165Recruiting
Genetics and blood testing for inherited bleeding disorders
This study looks at genes and blood function in people with inherited (passed-down) problems with platelets, white blood cells, or blood clotting. It may help improve understanding of the cause of these conditions and how they work in the body.
New York, New YorkAges Any age - NCT05965258Recruiting
Classify mitral regurgitation using heart scans
This study uses heart imaging to better understand different types of mitral valve leak (mitral regurgitation) and how it relates to heart pumping function. Results may help doctors match people to the most appropriate care based on scan “patterns.”
Cleveland, OhioAges 18 years+ - NCT06091566Recruiting

Common questions
- Are there clinical trials for function?
- Yes. Clin2 currently lists 2,474 recruiting function 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 function 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 function 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.
