Monitoring device tested in severe kidney and heart failure
This study checks how safe a small heart-pressure monitoring device is for people with advanced heart failure and severe kidney problems. It looks at whether doctors can continuously track heart filling/pressure to help manage symptoms and reduce risks.
Nîmes, GardAges 18–85 - NCT05431101Recruiting
Absorbable versus non-absorbable stitches after carpal tunnel surgery
This study compares two types of stitches used to close the skin after carpal tunnel release surgery. It may help show which stitch type leads to better healing and comfort afterward.

Quality of life after rectal surgery for advanced ovarian cancer
This trial studies how patients’ day-to-day quality of life changes after a specific type of rectal/low anterior resection during treatment for advanced ovarian cancer. It may help the medical team understand what symptoms and recovery needs to expect after surgery.
SeoulAges 18 years+ - NCT05434598Recruiting
Whole-genome testing added to standard testing for MDS
This study checks whether adding whole-genome sequencing (a deeper look at DNA) alongside standard genomic tests helps in evaluating myelodysplastic syndrome (MDS). It aims to see if this extra testing is useful and acceptable during routine care—especially for people newly being worked up for MDS.
St Louis, MissouriAges 18 years+ - NCT05437900RecruitingPhase 4
A heart test to guide stent placement using blood-flow measurements
This Phase 4 study tests a way to measure blood flow in heart arteries to help doctors choose the best stent plan. It may help improve safety and effectiveness for people having elective heart stent procedures for stable angina or certain heart attacks.
Aalst, Oost-VlaanderenAges 18–85 - NCT05443906Recruiting
Home exercise program for people with neurodegenerative conditions
This trial studies whether a home exercise program is safe and helpful for people with certain neurodegenerative conditions, including X-linked adrenoleukodystrophy and DARS2-related disease, as well as some other similar diagnoses. You would be asked to do exercises at home and be assessed on your walking and strength/safety.
Baltimore, MarylandAges 5–75 - NCT05444946Recruiting
Itraconazole alone versus with steroid pills for Aspergillus lung overlap
This trial compares itraconazole taken by mouth alone versus itraconazole plus steroid pills in people who have a mix of two Aspergillus lung conditions. It aims to see which approach works better to control symptoms and lung changes caused by Aspergillus infection.
Chandigarh, ChandigarhAges 15–90 - NCT05449548Recruiting
Lenalidomide for severe mouth ulcers from Behçet’s
This trial studies lenalidomide to treat frequent, ongoing mouth ulcers caused by mucosal Behçet’s syndrome. It’s meant for people whose mouth sores keep coming back despite standard treatments like steroid medicines and other immune-suppressing drugs.

Common questions
- Are there clinical trials for down syndrome?
- Yes. Clin2 currently lists 3,196 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.
