Recruiting studies
- NCT07857733RecruitingPhase 3
Extended treatment study for complex regional pain syndrome
This study gives an extended course of neridronate infusions to people who completed the earlier AMBTX-01-301 trial, to see if longer treatment safely keeps easing their chronic pain and other symptoms of complex regional pain syndrome (a long-lasting pain condition, often after an injury).
Phoenix, ArizonaAges 18 years+ - NCT06776783RecruitingPhase 3
Testing a new surfactant for breathing problems in premature babies
This study tests a new medicine called APC-0101, a type of surfactant, for premature babies with breathing problems (respiratory distress syndrome). It may help their lungs work better and reduce the need for more breathing support.
Little Rock, ArkansasAges 1 hour–1 day - NCT07503444RecruitingPhase 3
Fenfluramine for Rett syndrome symptoms
This study tests whether fenfluramine, a medication already used for seizures, can help people with Rett syndrome. It aims to see if it improves daily life and reduces symptoms.
Little Rock, ArkansasAges 5–35 - NCT07822763Recruiting
Carbohydrate drink before weight-loss surgery for faster recovery
This study tests whether drinking a special carbohydrate drink before weight-loss surgery can help your stomach and intestines recover faster after the operation. If you have metabolic syndrome and are planning certain types of bariatric surgery, this may help you improve your recovery.
Chongqing, Chongqing MunicipalityAges 18–65 - NCT00001727Recruiting
Understanding fibrous dysplasia and McCune-Albright syndrome
This study follows patients with fibrous dysplasia (a condition where normal bone is replaced by fibrous tissue) or McCune-Albright syndrome (a genetic condition affecting bone, skin, and hormones) to understand how these conditions develop and progress over time. There is no experimental treatment; researchers simply want to learn more about these rare conditions.
Bethesda, MarylandAges 1 day–100 years - NCT07643896Recruiting
Blood test for pregnancy risk assessment using fetal cells
This study tests a new blood test that looks for fetal cells in your bloodstream to check your baby's health during pregnancy. The test is non-invasive—just a regular blood draw—and aims to help identify pregnancy risks earlier than traditional methods.
Phoenix, ArizonaAges Any age - NCT05938543Recruiting
Brain stimulation and appetite in Prader-Willi syndrome
This trial studies whether targeted brain stimulation (TMS) can help with appetite and eating feelings in people with Prader-Willi syndrome. It also includes an MRI scan to measure brain-related effects, but only if you can safely have these scans.
Belmont, MassachusettsAges 18–64 - NCT03681964Recruiting
Check tests for suspected Sjögren’s syndrome
This study follows people who have signs that might mean Sjögren’s syndrome and looks at how well a standardized work-up identifies the condition. It may help doctors confirm the diagnosis earlier and more consistently.
BrestAges 18 years+ - NCT02967822Recruiting
Study of genes in MRKH syndrome and related families
This study looks at DNA (your genes) to better understand Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome. It may help researchers learn more about the condition, and it can include both people with MRKH and healthy family relatives.
ParisAges Any age - NCT03275480Recruiting
Registry study for myelodysplastic syndromes patients
This study is a database that collects information from people diagnosed with myelodysplastic syndromes. It may help researchers better understand the condition and how patients do over time.
Marseille, PACAAges 18 years+ - NCT03886662RecruitingPhase 1/Phase 2
LB-100 for low-risk MDS after prior treatment failure
This Phase 1/2 trial studies LB-100 in adults with low or intermediate-1 risk myelodysplastic syndromes (MDS). It may help by improving blood counts or disease control in people whose prior treatments have not worked or stopped working.
Tampa, FloridaAges 18 years+ - NCT03470467Recruiting
ICU study of a reversible brain swelling condition
This trial looks at Posterior Reversible Encephalopathy Syndrome (PRES) in adults in the ICU. It may help doctors better understand and manage a condition that can cause seizures, confusion, headaches, and vision problems, and that typically shows specific changes on brain scans.
Le ChesnayAges 18 years+ - NCT04087200Recruiting
High-dose statin early after heart attack to protect kidneys
This trial looks at whether starting a high dose of a statin (cholesterol medicine) right away after an acute coronary syndrome (a serious heart condition) can reduce future heart and kidney problems. It may help patients by testing a strategy meant to prevent complications soon after the event.
PratoAges Any age - NCT04217733RecruitingPhase 3
Ethosuximide plus pentoxifylline for IBS belly pain
This Phase 3 study tests whether two medicines (ethosuximide and pentoxifylline) can reduce belly pain from irritable bowel syndrome (IBS). It may help people whose IBS pain has been moderate to severe recently and who can keep their current IBS treatment steady.
TantaAges 18 years+ - NCT04167696RecruitingPhase 1
Dose-finding drug study for AML or MDS after standard options fail
This Phase 1 trial tests CYAD-02 to find the safest and recommended dose for people with AML or MDS that has returned or did not respond to prior treatment. It may help if you have limited treatment options, but participation also requires meeting specific heart, lung, and lab safety requirements.
Jacksonville, FloridaAges 18 years+ - 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+ - NCT04634487Recruiting
Registry for takotsubo heart condition in Poland
This is a registry study that collects information from people diagnosed with takotsubo syndrome. It helps researchers better understand the condition and may improve care in the future.
WarsawAges Any age - NCT04665726Recruiting
Natural history study of Usher syndrome hearing and vision changes
This study follows people with Usher syndrome over time to better understand how hearing and vision symptoms change. It may help researchers measure disease progression and support future treatments.
ParisAges Any age - NCT04947813Recruiting
Study links Alport genetics to kidney symptoms
This study looks at how specific genetic changes (genotypes) relate to kidney problems and urine blood findings in people with Alport syndrome. It may help doctors predict disease course and tailor care, though it may not involve new treatment.
ShanghaiAges Any age - NCT03613545RecruitingPhase 2/Phase 3
Fecal transplant to treat irritable bowel syndrome
This study tests whether transferring stool bacteria from a healthy donor (fecal microbiota transplantation) can improve symptoms of irritable bowel syndrome (IBS). It may help by changing the gut bacteria that can influence digestion and gut discomfort.
Guangzhou, GuangdongAges 18–75 - 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+ - NCT01403402Recruiting

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.
