Recruiting studies
- NCT03567213Recruiting
CortiCom brain signal system for communication in severe paralysis
This trial tests a system that records brain signals to help people with severe paralysis and little or no speech communicate. It involves a surgical implant and frequent study visits to see if the system can work safely and reliably for communication.
Baltimore, MarylandAges 22–70 - NCT03592563Recruiting
Brain health follow-up study for adults
This study follows adults over time to better understand brain health and brain-related conditions. You may join if you already have certain neurological or psychiatric diagnoses, are at higher risk, or simply want to help research on maintaining brain health.

Study of genetics and causes of systemic juvenile arthritis and Still's disease
This study aims to learn more about the causes and genetics of two related inflammatory conditions: systemic juvenile idiopathic arthritis (sJIA) in children and adult-onset Still's disease (AOSD) in adults. By studying patients and healthy volunteers, researchers hope to understand these diseases better and find better ways to treat them.
Bethesda, MarylandAges 1 day–100 years - NCT03474237Enrolling by invitation
Study following people newly diagnosed with adrenal conditions
This study follows adults with a new adrenal diagnosis to learn how adrenal diseases behave over time. It may help doctors better understand these conditions and improve future care.
SeoulAges 19 years+ - NCT03471260RecruitingPhase 1/Phase 2
Ivosidenib and venetoclax for IDH1-mutated leukemia or MDS
This Phase 1/2 study tests whether the medicines ivosidenib and venetoclax (with or without azacitidine) can help people with certain “IDH1-mutated” blood cancers like AML or high-risk MDS. It’s meant for patients whose disease has come back, doesn’t respond, or who can’t safely get standard chemotherapy.
Boston, MassachusettsAges 18 years+ - NCT03314974RecruitingPhase 2
Stem cell transplant study for blood cancers
This Phase 2 study tests a strong (myeloablative) stem cell transplant using donor stem cells (allogeneic transplant) for certain blood and bone marrow cancers. The goal is to see how well this approach works and whether it can improve outcomes for people who need transplant-level treatment.
Minneapolis, MinnesotaAges Up to 60 years - NCT03417856Enrolling by invitation
Study skin and blood signs in ichthyosis
This study looks at “skin and blood biomarkers,” meaning measurable signs in the body, in people with ichthyosis to better understand the condition. It may help researchers find ways to track disease activity and evaluate future treatments.
Chicago, IllinoisAges 1–60 - NCT03430037Enrolling by invitationPhase 2
Fisetin study to reduce frailty and inflammation in older women
This Phase 2 trial tests whether fisetin, a supplement, can reduce frailty and inflammation in postmenopausal women age 70 and older. If it works, it may help older adults feel stronger and have healthier body signals related to aging and inflammation.
Rochester, MinnesotaAges 70 years+ - NCT03478670Enrolling by invitation
Registry follow-up for ADA-SCID patients treated with Strimvelis
This study keeps track of people with ADA-SCID (a rare immune system condition) who previously received Strimvelis or a related treatment. It helps doctors understand long-term outcomes and safety after treatment.
Milan, LombardyAges Any age - NCT03368092RecruitingPhase 3
Inhaled medication to prevent lung failure after severe trauma
This trial tests whether inhaled dornase alfa can reduce the risk of respiratory (lung) failure in adults with severe trauma who are on a breathing machine in the ICU. If it works, it may help patients spend less time with dangerous breathing complications.
StrasbourgAges 18 years+ - NCT03385876Enrolling by invitation
Rapid whole genome sequencing for children with suspected genetic illness
This study quickly reads a child’s DNA using whole genome sequencing to look for genetic causes of symptoms. It may help families and doctors better understand an underlying genetic condition and guide medical care.
San Diego, CaliforniaAges Any age - NCT03371641Recruiting
Study of alcohol exposure effects in unborn babies
This study looks at unborn babies exposed to alcohol during pregnancy and compares them with babies not exposed. Researchers test a pregnancy blood marker to see whether it may relate to early brain changes in the baby.
RouenAges 18 years+ - NCT03509064Recruiting
Study of quality of life in Sjögren nerve pain
This trial looks at people with Sjögren who may have small-fiber nerve problems that can cause pain, temperature-related nerve symptoms, or body-function nerve issues. It aims to understand how these nerve problems affect quality of life and medical needs, and compare them with people without neuropathy.
ParisAges 18 years+ - NCT03173937RecruitingPhase 1/Phase 2
Cord blood transplant for severe aplastic anemia
This study tests a special cord blood transplant that may help your body start making blood cells faster than a regular transplant. It is for people with severe aplastic anemia or related bone marrow failure who have not gotten better with other treatments.
Bethesda, MarylandAges 4–75 - NCT03152058RecruitingPhase 2
Certolizumab for pregnancy in people with APS
This Phase 2 study tests whether certolizumab can improve pregnancy outcomes in people with antiphospholipid syndrome (APS). It targets pregnancy complications related to APS while closely checking safety, infections, and certain health conditions.
New York, New YorkAges 18–40 - NCT03281798Recruiting
Fetal bladder procedure for severe blockage in a baby boy
This trial studies a fetal cystoscopy procedure to treat severe urinary tract blockage in a baby boy during pregnancy. It aims to see whether the procedure helps improve outcomes, but it requires specific pregnancy conditions and testing beforehand.
Miami, FloridaAges 18 years+ - NCT03233646Recruiting
Retina scans in memory and nerve disorders
This study uses pictures of the back of your eye (retinal imaging) to look for differences in people with neurodegenerative diseases and compares them with people without these conditions. It may help researchers understand eye changes that could connect to brain or nerve health.
Durham, North CarolinaAges 18 years+ - NCT03223077Recruiting
Study of gut germs in new Campylobacter stomach illness
This trial studies how your gut germs (microbiome) and gut lining change during a new bout of Campylobacter infection. It may help researchers understand what drives symptoms and how the gut recovers.
Rochester, MinnesotaAges 18–80 - NCT03109197Recruiting
SUDC registry to study sudden unexplained child deaths
This registry collects information (and sometimes DNA) from families affected by sudden unexplained death, to help researchers learn possible underlying causes. If you qualify, you may be contacted about participating in a DNA study or completing family information.

Eye scans study to compare brain and eye health
This study uses detailed eye imaging to look for patterns that may go along with conditions like Alzheimer’s disease, memory problems, multiple sclerosis, or eye/vascular issues. It may help researchers better understand how eye findings relate to health and disease.
Miami, FloridaAges 18–99 - NCT03128996RecruitingPhase 1/Phase 2
Bone marrow transplant with lighter chemo for non-cancer illnesses
This early-phase study tests a safer “lighter” conditioning chemo plan before a bone marrow transplant for people with non-cancer blood and immune disorders. It aims to reduce transplant risk while using donor marrow that does not match perfectly in the HLA type.

Common questions
- Are there clinical trials for down syndrome?
- Yes. Clin2 currently lists 3,051 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.
