Follow-up study for rare epilepsy in children
This study follows children and teens with rare forms of epilepsy to better understand their condition over time in real-life care. It may help doctors improve future care plans and support for families.
AngersAges Up to 15 years - NCT05127616Recruiting
Trial for chronic pelvic pain: CBT vs education/support
This study tests whether structured talking therapy (CBT) or education/support helps reduce chronic pelvic pain problems in adults. It compares two approaches over time and uses symptom diaries and follow-up check-ins to see which works better.
Los Angeles, CaliforniaAges 18–70 - NCT05146336Recruiting
CytoSorb registry for critically ill patients needing blood treatment
This registry collects information about critically ill patients who receive the CytoSorb 300 mL blood treatment. It may help doctors better understand when the treatment works best and when it should not be used.
KlagenfurtAges Any age - NCT05212129Recruiting
Stimulation of the ear nerve to help gut symptoms
This study tests whether stimulating a nerve in the ear (called auricular vagal nerve stimulation) can improve upper gut symptoms in teens who may have hypermobile Ehlers-Danlos syndrome (hEDS) or hypermobile spectrum disorder (HSD). It also checks whether this treatment helps nerves that control the body (autonomic nervous system) and how well the gut moves.
Milwaukee, WisconsinAges 10–18 - NCT05231798RecruitingPhase 2
PET and brain scans in adults with Down syndrome
This study looks at how well a brain chemical system works in adults with Down syndrome as they age, including how it relates to Alzheimer’s-type brain changes and thinking skills. It uses brain scans and memory/thinking tests to see whether these measures can help track risk or changes over time.
Nashville, TennesseeAges 18–55 - NCT05293184Recruiting
Angelman syndrome registry to track symptoms worldwide
This trial is building a global registry for people diagnosed with Angelman syndrome. It helps researchers learn more about how symptoms change over time, which can support future studies and treatments.
Brisbane, QueenslandAges Any age - NCT05421273Recruiting
Testing two spinal stimulation patterns for long-term back pain
This study compares two ways of delivering spinal cord stimulation to see which better reduces pain in people with persistent spinal pain syndrome type 2. You would be assigned to one of the stimulation “burst” patterns and followed for changes in your pain experience.
Arnhem, GelderlandAges 18–70 - NCT05468580Recruiting
Release or sham surgery for clogged celiac artery
This trial studies whether a surgical “release” of the celiac artery (to improve blood flow) helps people with MALS who have specific symptoms and artery narrowing. Some people will have a sham (placebo) procedure to compare outcomes, so you’ll be closely monitored either way.
Enschede, OverijsselAges 18 years+ - NCT05761314Recruiting
Study treatments for cancers in people with RASopathy
This study looks at people who have a RASopathy—a genetic condition—and also have solid tumors (tumor growths not in blood). To join, your RASopathy must be confirmed by genetic testing, not only by symptoms.
RomaAges Any age - NCT05786768RecruitingPhase 2/Phase 3
Obinutuzumab vs rituximab for relapsing childhood kidney syndrome
This study compares two antibody medicines, obinutuzumab and rituximab, to prevent relapses of steroid-dependent or frequently relapsing nephrotic syndrome in children. It looks at whether one option works better and is safer, including infection risk.

Common questions
- Are there clinical trials for down syndrome?
- Yes. Clin2 currently lists 3,182 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.
