WarsawAges Any age - NCT04650880Recruiting
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.
Hong KongAges 18–40 - 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 - NCT04689646Recruiting
Mind-body therapy for chronic back pain
This study tests whether a mind-body therapy approach can reduce disability and how bothersome chronic back pain feels. It may help people whose pain has lasted for months and affects daily life.
Boston, MassachusettsAges 18–67 - NCT04699279Recruiting
Statin after aortic surgery to protect heart and organs
This trial tests whether taking a cholesterol-lowering medicine (a statin) after certain aortic surgeries can reduce harmful changes in the heart and other organs. You might benefit by lowering the risk of ongoing damage after your acute aortic condition and surgery.
Guangzhou, GuangdongAges 18–85 - NCT04709900Recruiting
Tests for stable chest pain using heart scans and pressure measurements
This trial studies how well different heart tests (imaging the blood flow and measuring blood pressure in the heart) work for people with stable chest pain. It may help guide safer, more accurate evaluation when you are not having a heart attack.
CopenhagenAges Any age - NCT04745195Recruiting
Study of complement activity in microangiopathy affecting kidneys
This study looks at signs of a clotting problem in tiny blood vessels (called TMA) that can affect kidney function. The goal is to better understand the role of the body’s complement system and how it relates to different causes of this illness.
Maastricht, LimburgAges 18 years+ - NCT04804943Recruiting
Testing an added breathing therapy for ARDS patients on ventilators
This pilot study tests NOA-001, a treatment given to people with ARDS (a serious lung condition) who are already on a breathing machine. It looks at whether the treatment can improve outcomes in ARDS caused by either non-COVID illnesses or COVID-19.
TokyoAges 16 years+ - NCT04829526Recruiting
Study of suspected Guillain-Barré syndrome cases
This is an observational study that looks at people who were suspected to have Guillain-Barré syndrome and were cared for at University Hospital of Basel in the past. It does not test a new treatment—researchers review existing care to learn more about this condition.
BaselAges 18 years+ - NCT04848870Recruiting
Check dental and gum health in Sjögren’s disease
This study looks at dental and gum (periodontal) health in adults with Sjögren’s syndrome. It may help researchers understand how Sjögren’s affects the mouth and how patients can be supported better.
Ivry-sur-Seine, Île-de-France RegionAges 18 years+ - NCT04851678Recruiting
Study how stress affects adults with Tourette syndrome
This study follows adults with Tourette syndrome over time to better understand how stressors affect symptoms and daily life. It may help researchers learn what factors make symptoms better or worse and improve future care.
Nashville, TennesseeAges 18 years+ - NCT04898647Recruiting
Study of blood thickness in Waldenström’s disease
This study looks at “hyperviscosity,” meaning very thick blood, in people with Waldenström macroglobulinemia (WM). Your results may help doctors better understand who needs treatment and what tests should be used, even if thick blood is not found.
AmiensAges 18 years+ - NCT04904146Recruiting
Testing blood or tumor markers in skin lymphoma patients
This study looks for “predictive” and “prognostic” biomarkers—measurable signs in blood or tissue—to help predict how mycosis fungoides or Sézary syndrome will behave and how patients may respond to care. It may help doctors better understand outcomes for people with these skin lymphomas.
LundAges 18–100 - NCT04918329Recruiting
Digestive symptom check-in study for adults
This study follows adults with long-lasting “functional” digestive symptoms as part of routine care. It may help researchers better understand these conditions and improve how they are managed.
RouenAges 18 years+ - NCT04920149RecruitingPhase 2
Mesalamine to help prevent colon cancer in Lynch syndrome
This trial tests whether mesalamine, a medicine used for bowel inflammation, can help prevent colorectal cancer in people with Lynch syndrome who do not currently have cancer. It may help by lowering the chance that new pre-cancer growths form over time.
AalborgAges 30 years+ - NCT04931160Recruiting
Study for suspected Sjögren’s disease diagnosis
This study follows people who may have Sjögren’s disease to better understand how to diagnose it. If you have symptoms like dry eyes or dry mouth, this could help researchers confirm the diagnosis and learn what tests best explain it.
BrestAges 18 years+ - NCT07697924Recruiting
Cord blood therapy for thin uterine lining
This study tests if a special treatment made from cord blood can help women with a thin uterine lining (the inner layer of the womb) or Asherman syndrome (scar tissue). The goal is to see if it can improve the lining so it's healthier for pregnancy.

Common questions
- Are there clinical trials for down syndrome?
- Yes. Clin2 currently lists 3,195 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.
