Recruiting studies
- NCT04278404Recruiting
Drug safety study for children already on certain medicines
This study measures how certain medicines move through the body and checks their safety in children. It may help doctors better understand dosing and side effects in kids who are already receiving these treatments, or in some kids who recently tested positive for COVID-19.
Phoenix, ArizonaAges birth–20 years - NCT04323904Recruiting
Hantavirus registry for people with kidney or lung symptoms
This study is a registry, meaning it collects health information and possibly test results from people who have evidence of hantavirus infection along with specific illness symptoms. It may help researchers better understand how hantavirus affects the kidneys or the heart/lungs (and how to recognize it).
Cologne, North-Rhine WestfaliaAges Any age - NCT04330118Recruiting
Study immune cells in DRESS and drug rash reactions
This trial studies how certain immune cells (eosinophils) behave during severe drug reactions like DRESS and during milder drug rashes. It may help doctors understand what drives organ damage and improve how these reactions are managed.
ArrasAges 18 years+ - NCT04367246Recruiting
TP53 (Li-Fraumeni) family biobank and sample study
This study collects and stores health information and biological samples from people who have a known TP53 change (Li-Fraumeni syndrome) and from close family members. The goal is to help researchers learn more about risks and future treatments for this genetic condition.
Philadelphia, PennsylvaniaAges Any age - NCT04390646RecruitingPhase 2/Phase 3
Hormone treatment to study thinking in Down syndrome
This trial studies whether a GnRH hormone treatment can improve thinking and memory in people with Down syndrome. It also checks safety and whether the treatment affects brain-related changes seen on MRI.
Lausanne, Canton of VaudAges 16–50 - NCT04391335Recruiting
Breathing tests to spot lung scarring after stem cell transplant
This study checks new ways to measure breathing in children who had a stem cell transplant to better detect a lung condition called bronchiolitis obliterans syndrome. If you join, you’ll do breathing and imaging tests, and researchers will look for patterns that may help with diagnosis.
Toronto, OntarioAges 6–18 - NCT04402086Recruiting
Rheumatology patient and skin sample registry study at Yale
This study builds a health record and blood/skin sample collection for people with rheumatic autoimmune diseases who are getting care at Yale. It may help researchers understand these conditions and develop better tests or treatments over time.
New Haven, ConnecticutAges 18–99 - NCT04419649RecruitingPhase 2
Elritercept for anemia in lower-risk myelodysplastic syndromes
This trial tests elritercept, a medicine meant to improve anemia (low blood count) in adults with certain lower-risk bone marrow disorders called MDS. If you qualify, the study may help reduce the need for blood transfusions or improve anemia symptoms.
Duarte, CaliforniaAges 18 years+ - NCT04431024Recruiting
Testing imaging and biopsy options for people with BAP1 risk
This study looks at how well advanced scans, liquid biopsy tests, and small follow-up procedures can find early mesothelioma in people with a high-risk BAP1 gene condition. It may help catch cancer earlier when treatment could work better.
Bethesda, MarylandAges 30–120 - NCT04449068Recruiting
Tourette research using records from deep brain stimulation patients
This study is collecting information about people with severe Tourette syndrome who are not adequately helped by medication and may receive deep brain stimulation. It helps researchers understand outcomes and care patterns for this treatment over time using an observational database.
ParisAges 15 years+ - NCT04460521RecruitingPhase 4
NAC pills and night splints for carpal tunnel without surgery
This trial tests whether N-acetylcysteine (NAC) along with wearing a night wrist splint can improve symptoms of mild to moderate carpal tunnel syndrome. It’s designed for people who want a non-surgical option.
Halifax, Nova ScotiaAges 18 years+ - NCT04472260Recruiting
Testing safe early standing for adults with severe lung failure
This trial checks whether it’s safe and doable to help people with acute respiratory distress syndrome (ARDS) start standing early, while they are closely monitored. It may help some patients begin upright movement sooner, with the goal of improving safety.
OrléansAges 18 years+ - NCT04493164RecruitingPhase 2
CPX-351 plus ivosidenib for IDH1-mutated leukemia or high-risk MDS
This trial tests CPX-351 together with ivosidenib in people with IDH1-mutated acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS). It aims to improve disease control, especially in tumors with a specific genetic change called IDH1.
Houston, TexasAges 18 years+ - NCT04507997Recruiting
Study of the natural course of Angelman syndrome
This study follows people with Angelman syndrome to understand how their symptoms and development change over time. It may help researchers better describe the condition and support future treatments.
Los Angeles, CaliforniaAges Any age - NCT04518423Recruiting
Study frailty and fitness changes in older adults living at home
This study looks at how “frailty” (lower strength and resilience) and “pre-frailty” change over time in older adults who live at home. It may help researchers understand what factors affect aging and strength, so future care can start earlier.
OpoleAges 65 years+ - NCT04522193Recruiting
Testing causes of dumping symptoms after esophagus repair
This study looks at how sugars move and how “dumping” symptoms happen in babies after surgery for an esophagus problem. It may help doctors understand what causes these symptoms and how to monitor them safely.
LilleAges 2 months–3 months - NCT04529330Recruiting
Study for certain tibia fractures in adults
This trial is studying care for adults with a specific type of fracture around the knee (Schatzker types V or VI). You may be asked about the type of injury and what treatment you received so researchers can compare outcomes.
Shijiazhuang, HebeiAges 18 years+ - NCT04543253Recruiting
Recovery study after Cushing surgery for cortisol excess
This study looks at how people recover after surgery to treat Cushing syndrome and mild cortisol overproduction. It may help doctors understand what recovery looks like and how treatment affects cortisol levels and symptoms.
Rochester, MinnesotaAges 18 years+ - NCT04541654Recruiting
Study of families with TP53 gene changes in Li-Fraumeni syndrome
This study is looking at how people in families with certain TP53 gene changes (including Li-Fraumeni syndrome) develop health problems over time. It may help doctors better understand risk and improve care for affected families.
Boston, MassachusettsAges Any age - NCT04575844RecruitingPhase 4
Exercise and GLP-1 to improve insulin and muscle blood flow

Hydrocortisone and vasopressin for shock after cardiac arrest
This Phase 3 trial tests whether hydrocortisone plus vasopressin (or related hormone treatments) can improve shock in adults after a resuscitated cardiac arrest. It targets people who remain very low in blood pressure despite fluids and need strong IV medicines to maintain blood pressure.
AmiensAges 18 years+ - NCT04606693Recruiting

Vitamin D study for irregular periods from PCOS
This trial studies whether taking vitamin D can improve ovulation (the release of an egg) in people with PCOS who have long, irregular menstrual cycles. It may help some participants have more regular ovulation and cycle timing, but you would be monitored with vaginal ultrasound and blood tests.

Common questions
- Are there clinical trials for down syndrome?
- Yes. Clin2 currently lists 3,189 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.
