7-tesla MRI for symptoms after a mild concussion
This study checks whether a stronger MRI scan (7-tesla) can help diagnose and better understand ongoing symptoms after a mild concussion. You would be scanned about 7 days after your injury to compare results with typical care.
PoitiersAges 20–72 - NCT04999943RecruitingPhase 1
Testing two blood-cancer medicines plus eDC in older MDS patients
This early-phase study tests a combination of two standard medicines for myelodysplastic syndrome (MDS) along with an added eDC therapy in people age 60 and older. It may help improve blood counts or disease control for those who cannot or do not want stem cell transplant.
BeijingAges 60 years+ - NCT05010122RecruitingPhase 1/Phase 2
Testing venetoclax and gilteritinib with ASTX727 for FLT3 leukemia
This Phase 1/2 trial tests a combination of medicines (ASTX727, venetoclax, and gilteritinib) for adults with FLT3-mutated acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS). It aims to see how well the treatment works and how safe it is for people whose disease has come back, is not responding, or (for some) is newly diagnosed.
Houston, TexasAges 18 years+ - NCT05012111Recruiting
Study of bone marrow failure causes over time
This study looks at the natural history (how a condition progresses) in people with acquired or inherited bone marrow failure syndromes, including related lung and liver findings in some cases. It helps researchers understand underlying causes—sometimes linked to gene or telomere changes—and how symptoms evolve, which may guide future care.
Bethesda, MarylandAges 2–99 - NCT05012475Recruiting
Test whether video games help arm movement in Rett syndrome
This trial looks at whether computer gaming can improve how well you can use your arms to control game actions in Rett syndrome. It checks whether the gaming tasks can be done safely based on your arm movement range.
Washington D.C., District of ColumbiaAges 4–60 - NCT05034835Recruiting
Compression garments for arm nerve pain in CRPS
This study tests whether wearing a special compression sleeve or garment can reduce pain in people with complex regional pain syndrome (CRPS) affecting the arm. It’s looking at pain changes while making sure it’s safe for your skin and blood flow.
Ploemeur, Brittany RegionAges 18 years+ - NCT05044520Recruiting

Common questions
- Are there clinical trials for down syndrome?
- Yes. Clin2 currently lists 3,195 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.
