Eye tests to measure visual speed in multiple sclerosis
This study tests how fast and how accurately your eyes process visual information and how eye movements look in people with multiple sclerosis. It may help researchers understand vision-related effects of MS using objective eye measurements.
Valladolid, ValladolidAges 18–80 - NCT05604430Enrolling by invitation
Study of pre-hospital breathing support with a specific ventilator
This study looks at breathing support given outside the hospital using a particular ZOLL ventilator model and software version. If you were treated with the right equipment, the team will use the ventilator’s recorded data to evaluate how ventilation was delivered.

Oakland, CaliforniaAges Any age - NCT05573542Enrolling by invitation
Study early Parkinson signs in people with IBS
This study looks for early clues of Parkinson’s disease in people who have IBS (irritable bowel syndrome), and compares them with people without IBS. The goal is to understand whether gut symptoms or test results can help spot Parkinson’s earlier.
ÖrebroAges 18–85 - NCT05561153Enrolling by invitation
Study of knee movement issues in patellofemoral pain
This study looks at how the nerves and muscles are working in people with patellofemoral pain (pain around the kneecap). It may help researchers understand what drives the pain and how it might be treated.
AnkaraAges 18–40 - NCT05513417Enrolling by invitation
Digital pelvic health program for women with pelvic pain

Common questions
- Are there clinical trials for down syndrome?
- Yes. Clin2 currently lists 3,176 recruiting down syndrome 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 down syndrome 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 down syndrome 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.
