Baltimore, MarylandAges 50–89 - NCT05662111RecruitingPhase 2
Etidronate treatment for brain calcifications in Fahr disease
This Phase 2 study tests whether etidronate (a medicine that affects bone-calcium handling) can help people with Fahr disease or a similar condition marked by calcium deposits in the brain. It will also check safety and whether certain tests can track changes over time.
Utrecht, UtrechtAges 18 years+ - NCT05637294Recruiting
Compare night-only versus full-time splinting for carpal tunnel
This study looks at whether wearing a wrist splint only at night works as well as wearing it full-time for carpal tunnel syndrome (CTS). It may help you find the most helpful and practical splint schedule to reduce symptoms.
HelsinkiAges 18 years+ - NCT05640271RecruitingPhase 2
Tocilizumab for acute chest syndrome in sickle cell
This trial studies tocilizumab (a medicine that calms inflammation) to treat acute chest syndrome in people with sickle cell disease. It may help improve symptoms and recovery by targeting key immune signals involved in this complication.
Chicago, IllinoisAges 12 years+ - NCT05663216Recruiting
Study of fluid leaks in serious whole-body inflammation
This trial looks at what causes blood vessels to “leak” fluid during a dangerous whole-body inflammation response. It may help doctors understand why some people develop fluid buildup and aim for better monitoring and care in the ICU.
ParisAges 18 years+ - NCT05628948Recruiting
Donate blood for a heart and metabolism research biobank

Common questions
- Are there clinical trials for down syndrome?
- Yes. Clin2 currently lists 3,057 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.
