If you are starting a new anti-TNF treatment, this study may help doctors understand if the medication will be effective for you.
Changsha, HunanAges 18–80 - NCT07662902Enrolling by invitation
Gut Barrier Study in Ulcerative Colitis Remission
This study looks at gut barrier function in people with ulcerative colitis who are in remission. It uses a non-invasive liver test to check for subtle changes in the body.
ZagrebAges 18–70 - NCT06956703Recruiting
Nottingham IBD study testing new treatments
This study looks at people with active Crohn's disease or ulcerative colitis starting a new type of medication (anti-TNF, ustekinumab, upadacitinib, or vedolizumab), as well as people without IBD having a routine colonoscopy. It aims to collect information to better understand how these treatments work.
Nottingham, NottinghamshireAges 16 years+ - NCT07093294Recruiting
Predicting vedolizumab success with ultrasound in early Crohn's
This study uses intestinal ultrasound to see if vedolizumab can heal the gut in people recently diagnosed with Crohn's disease. It aims to find early signs that the treatment is working.
Changsha, HunanAges 18–80 - NCT06329453Recruiting
Gut immunity and brain health study
This study looks at how your gut's immune system relates to brain and nerve diseases. Researchers will collect samples during a colonoscopy to better understand connections between gut health and neurologic conditions like multiple sclerosis or Parkinson's disease.
North Haven, ConnecticutAges 18–99 - NCT06858553Recruiting
AI-assisted MRI for intestinal scarring in Crohn's disease
This trial uses AI to improve MRI scans for detecting intestinal fibrosis (scarring) in people with Crohn's disease who are scheduled for surgery. It aims to help doctors better identify and treat scarring.
Guangzhou, GuangdongAges 18–75 - NCT06606678Enrolling by invitation
Physical activity for better metabolism and health
This study looks at how regular exercise can help improve your metabolism, lower inflammation, and support your gut health. If you're over 50 and can safely be active, this trial may be a good fit.
PoznanAges 50 years+ - NCT04444362Enrolling by invitation
Probacine to protect organs after cardiovascular surgery
This study tests whether a medicine called Probacine can help protect your gut and organs after cardiovascular surgery. If you qualify, you may be asked to take part and follow the study plan to see if complications are reduced.
Beijing, Beijing MunicipalityAges 18–90 - NCT04896684Recruiting
Study collecting gut health information from adults’ scans
