Ulcerative colitis clinical trials, in English

UC studies usually require a Mayo or similar endoscopy score and a defined extent of colitis. Hospitalized acute severe UC is a different protocol from outpatient moderate disease. We list recruiting registry cards without ranking treatments. Sourced from ClinicalTrials.gov. Not a recommendation to join any study.

Inflammatory Bowel Diseases (IBDs), including ulcerative colitis and Crohn's disease (CD), constitute a group of debilitating chronic diseases that profoundly impact patient quality of life and incurs large costs in terms of treatment and lost productivity. Incidence of IBD is rising worldwide, and there is a pressing clinical need for development of new therapies.

Phase 4: testing Vedolizumab IV for Ulcerative Colitis

Ulcerative Colitis (UC) and Crohn's Disease (CD) are long-term conditions in the gut that can cause diarrhea, swelling (inflammation), bleeding from the anus, and belly pain. The main aim of this study is to check for how many participants with UC and CD signs and symptoms disappear after 3.5 months (14 weeks) of treatment with Vedolizumab (this is called remission).

This watch-and-measure (no experimental treatment required) study aims to identify genes that may affect how patients with inflammatory bowel disease respond to anti-TNF treatment and why some patients lose response to treatment over time. The study will examine whether genetic markers can help predict which patients are more likely to respond to anti-TNF therapy.

Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, is a chronic relapsing intestinal disorder driven by immune dysregulation, impaired mucosal barrier function, and gut microbiome dysbiosis. Although current therapies can control inflammation, many patients still experience recurrent symptoms, treatment resistance, adverse effects, and impaired quality of life.

FAQ: Ulcerative colitis trials

How do I find recruiting Ulcerative colitis clinical trials?

This hub lists 38 recruiting Ulcerative colitis studies from a ClinicalTrials.gov snapshot, rewritten in plain English. Each card links to its NCT record. You can also search the official registry for “ulcerative colitis” at https://clinicaltrials.gov/search?cond=ulcerative%20colitis.

What does a Ulcerative colitis trial page on PlainTrials include?

A phase explainer, a plain-English summary grounded in the brief summary, inclusion/exclusion extracted from the public eligibility block, sponsor name, and any central contact the sponsor published. It is not a match to a trial.

Where are Ulcerative colitis studies located in this snapshot?

Sites that appear on these records include São Paulo, Brazil; Berlin, Germany; Budapest, Hungary; Warsaw, Poland; New York, New York. A city on a record is not a guarantee that the site is taking new patients this week — call the NCT contact.

Can PlainTrials tell me if I qualify for a Ulcerative colitis study?

No. Eligibility is decided by the study team using the protocol, labs, and consent. Our “who it is for” list is a readable extract of public inclusion text only.
