LondonAges 18 years+ - NCT04356469RecruitingPhase 2
Donor stem cell transplant for serious blood disorders in children
This trial tests a special type of donor stem cell transplant (with donor T-cells removed) to treat serious non-cancer blood problems in children. It may help by resetting the bone marrow so the body can make healthy blood cells again.
St. Petersburg, FloridaAges birth–21 years - NCT03963622Recruiting
Test of careful breathing support for severe lung distress
This study compares a more careful ventilation approach for people with severe lung breathing failure (ARDS). It aims to improve outcomes by using a specific strategy for how the ventilator controls breathing.
New York, New YorkAges 18 years+ - NCT04221737Recruiting
Early breathing support for ARDS using a pressure release ventilator
This study looks at starting a specific type of breathing machine setting early in people with ARDS (a serious lung problem) to see if it improves outcomes. You might be able to take part if you are within 48 hours of needing a breathing tube and meet the lung oxygen criteria.
Guadalajara, JaliscoAges 18–80 - NCT04186078Recruiting
Study symptoms and traits of sleep apnea in Korea
This study looks at people in Korea who may have sleep apnea based on common symptoms. The goal is to better understand who has sleep apnea and how it shows up, which may help improve future diagnosis and care.
SeoulAges 19 years+ - NCT04194619Recruiting
Study of pregnancy safety in women with rare blood-vessel diseases
This study looks at pregnancy and the early period after birth in women with rare diseases that affect blood vessels. It may help doctors understand risks and improve care for future pregnancies.
AngersAges 18–45 - NCT04195633RecruitingPhase 2
Haploidentical donor stem cell transplant to treat blood cancers
This Phase 2 trial tests whether a specific stem cell transplant method (from a related “half-matched” donor) plus conditioning chemo and radiation can improve outcomes for several blood cancers. It may help people whose cancer is in remission but still considered high risk, or those who have had limited response after prior treatment.
Seattle, WashingtonAges 6 months+ - NCT04174066Recruiting
Study on kidney damage in children and adults with MGLS or FSGS
This trial collects medical data and blood/urine samples from patients with minimal change disease or focal segmental glomerulosclerosis (FSGS) to better understand how the immune system damages kidney cells.

Common questions
- Are there clinical trials for down syndrome?
- Yes. Clin2 currently lists 3,055 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.
