Study of new cases of several spine, joint, and eye diseases
This study enrolls people who have recently been diagnosed with certain inflammatory conditions affecting the spine, joints, or the eye. Researchers are looking to better understand how these illnesses start and how they may be linked, which could help guide future care.
BerlinAges Any age - NCT01731665Recruiting
Study of Crohn’s and ulcerative colitis in Seoul
This study looks at how inflammatory bowel disease (Crohn’s disease and ulcerative colitis) affects people in a specific area of Seoul. It mainly focuses on describing patterns and health needs rather than testing a new drug.
SeoulAges Any age - NCT01140789Recruiting
Study comparing people with and without bowel inflammation
This study looks at people with inflammatory bowel disease (Crohn’s disease or ulcerative colitis) and compares them with people without it. Researchers want to understand differences that may help explain or better detect the disease.
Hong KongAges 18 years+ - NCT02523118Recruiting
Measuring symptoms and test results in eosinophilic gut diseases
This study looks at how eosinophilic inflammation in the esophagus and intestines affects outcomes like symptoms and test findings. It may help clinicians better understand these conditions and track what changes over time.
Phoenix, ArizonaAges 3 years+ - NCT02636517Enrolling by invitationPhase 1
Fecal microbiome transplant for repeat C. difficile infection
This Phase 1 study tests whether transferring healthy gut bacteria (a fecal microbiome transplant) can help children with repeated or moderate-to-severe C. difficile infection. It focuses on changing gut bacteria to reduce ongoing infection and symptoms.
Philadelphia, PennsylvaniaAges 3–21 - NCT02791854Enrolling by invitation
Improving Care for Adults With Crohn’s or Ulcerative Colitis
This trial looks at ways to improve care for adults living with inflammatory bowel disease, including Crohn’s disease and ulcerative colitis. You may be invited if your clinic is part of an inflammatory bowel disease care network called IBD Qorus.
Los Angeles, CaliforniaAges 18–99 - NCT07431983Recruiting
IBUS vs colonoscopy and enterography for UC and CD
This study compares a newer, possibly greener imaging method (IBUS) with standard colonoscopy and enterography for people with ulcerative colitis (UC) or Crohn's disease (CD). The goal is to see if IBUS is as helpful and produces less waste or carbon emissions.
Hyderabad, TelanganaAges 18–80 - NCT07433946Recruiting
Liquid nutrition to prevent weight loss in IBD
This study tests whether adding a special liquid nutrition drink (partial enteral nutrition) to your regular diet can help prevent weight loss and muscle loss in people with Crohn's disease or ulcerative colitis who are at risk of malnutrition.
Rozzano, MilanoAges 18–65 - NCT07487480Recruiting
Guselkumab for Crohn's after ustekinumab

Real-world outcomes of guselkumab for ulcerative colitis or Crohn's disease
This study tracks how well guselkumab (a biologic medication that blocks IL-23, a protein that drives inflammation) works for moderate-to-severe ulcerative colitis or Crohn's disease in everyday clinical practice. Researchers want to understand long-term benefits and safety in real patients.

Probiotic Supplements for Ulcerative Colitis Remission
This trial tests whether taking sodium butyrate (a short-chain fatty acid) and a specific probiotic yeast called Kluyveromyces marxianus can help keep ulcerative colitis in remission and prevent flare-ups. You'd need to be in remission (symptom-free with no active inflammation) when you start.
PadovaAges 18–75 - NCT07593352Recruiting
