Recruiting studies
- NCT05202210Recruiting
Biobank study for people with Noonan syndrome
This study collects biological samples to better understand what causes Noonan syndrome. If you qualify, your participation could help researchers learn how the condition works and guide future care.
ToulouseAges 18–99 - NCT05212571Enrolling by invitation
IV esketamine to improve long-term pain in CRPS
This study looks at whether giving esketamine through a vein can help reduce long-term pain in people with complex regional pain syndrome (CRPS). You may be able to join if your CRPS diagnosis matches specific international criteria and you can safely take the study medicine.
Rotterdam, South HollandAges 18 years+ - NCT05224323Recruiting
Testing a lung opening breathing pattern in early ARDS
This study looks at a specific breathing event (“avalanche phenomenon”) when the lungs are opened in people with early, moderate-to-severe ARDS. The goal is to understand what’s happening in the lungs and whether it can guide better care.
PoitiersAges 18 years+ - NCT05237505RecruitingPhase 2
Sleep apnea plus COPD study to check heart and breathing effects
This Phase 2 study looks at the cardiovascular (heart/blood vessel) effects of having both sleep apnea and COPD. It may help doctors better understand who is at risk and how to manage these breathing problems together.
La Jolla, CaliforniaAges 40–79 - NCT05256160Recruiting
Study brain excitability in people with cyclic vomiting syndrome
This study looks at how sensitive your brain is (brain “excitability”) in people with cyclic vomiting syndrome (CVS). It may help researchers understand what is happening in the brain during CVS and how it could be treated in the future.
Pittsburgh, PennsylvaniaAges 18–60 - NCT05143996RecruitingPhase 1
First study drug for relapsed AML or MDS
This Phase 1 trial tests CLN-049 in adults whose acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) has come back or did not respond to treatment. The goal is to find out how well the drug can work and how safe it is in people with limited options.
Birmingham, AlabamaAges 18 years+ - NCT05196984Recruiting
Gamma brain stimulation study for adults with Down syndrome
This trial tests a brain stimulation approach aimed at affecting brain activity in people with Down syndrome. It may help researchers understand whether this kind of stimulation can improve certain brain or thinking-related outcomes.
Cambridge, MassachusettsAges 25–65 - NCT05157581Recruiting
Light-based treatment for Sezary syndrome patients
This trial tests whether a special light treatment done outside the body (extracorporeal photopheresis) can help people with Sezary syndrome. It is meant to see if the treatment is safe and effective for this specific type and stage of skin lymphoma.
Atlanta, GeorgiaAges 18–100 - NCT05163899Recruiting
Surgery to release an occult tethered cord
This trial studies whether a specific back surgery (cutting/releasing part of the filum terminale) helps people with an “occult” tethered cord syndrome when symptoms have not improved with medicine. It may help by reducing traction on the spinal cord to improve bladder/bowel, skin, or nerve-related symptoms.
New York, New YorkAges 2–80 - NCT05090345Recruiting
Registry for young people getting bone marrow transplants
This trial is a registry that follows children and young adults up to age 26 who are having a bone marrow transplant, to better understand complications related to blood vessel and organ injury. It may help future patients by improving how doctors predict and prevent these problems.
Rochester, MinnesotaAges birth–26 years - NCT05092451RecruitingPhase 1/Phase 2
CD70-targeting NK cell therapy for blood cancer relapse
This study tests an immune therapy made from cord blood “NK cells” that are engineered to attack cells with a marker called CD70. It’s given after chemotherapy that reduces your blood and immune system, aiming to treat relapse or refractory (not responding) blood cancers.
Houston, TexasAges 12–80 - NCT03663348Recruiting
Patient registry for Takotsubo (stress) heart syndrome
This study is a patient registry that collects information from people diagnosed with Takotsubo syndrome, also known as a stress-related heart condition. It may help researchers learn more about who is affected and how the condition behaves over time.
New York, New YorkAges 18–110 - 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+ - NCT05066217RecruitingPhase 3
Study tests clemizole for Lennox-Gastaut seizures
This Phase 3 trial studies whether clemizole helps reduce seizures in people with Lennox-Gastaut syndrome (LGS) and checks safety. If you have LGS and meet the seizure and heart-safety requirements, this could be an option to explore.
Little Rock, ArkansasAges 2–55 - NCT05012111Recruiting
Studying bone marrow failure over time
This study looks at the natural course of bone marrow failure conditions, both inherited and acquired. It aims to understand how these diseases progress over time, which may help guide future treatments.
Bethesda, MarylandAges 2–99 - NCT05026645Enrolling by invitation
After a chemical, biological, or nuclear disaster exposure
This trial studies how patients are medically managed after being exposed to a chemical, biological, radiological, or nuclear (CBRNE) attack. It may help improve care for people who are treated after these rare disasters, using real medical information recorded by hospital staff.
College Park, MarylandAges Any age - NCT05002478Recruiting
Prone positioning for very sick babies with lung distress
This trial tests whether turning very sick, ventilated infants onto their stomach (prone positioning) can improve breathing when they have severe lung distress from likely pneumonia or bronchiolitis. It may help your baby get better oxygen levels and recover faster, while doctors closely monitor safety.
ViennaAges Up to 1 year - 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+ - NCT04982562Recruiting
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 - NCT04970459Recruiting
Collecting samples for Marfan and related conditions
This study collects biological samples and related health information for people with Marfan syndrome or similar inherited conditions. It helps researchers better understand these conditions and may lead to improved care for patients in the future.

Common questions
- Are there clinical trials for down syndrome?
- Yes. Clin2 currently lists 3,060 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.
