Active clinical trials for "Colitis, Ulcerative"

The purpose of this study is to assess the safety and tolerability, efficacy, and biomarker response of BMS-986165 administered orally in participants with moderate to severe ulcerative colitis. The study was originally designed to test deucravacitinib at two doses for 12 weeks compared to placebo. After the initial 12-Week period, all subjects receive active therapy (open-label extension). With protocol amendment 2, one of the dose treatment arms is being removed from the 12-week double blind period with no change to the open-label extension.

The TRIUMPH study was designed to build on the existing literature by studying the efficacy of tofacitinib in hospitalized patients with acute severe ulcerative colitis. This trial will provide evidence for a possible new indication for the use of tofacitinib.

This study assesses the long-term safety and efficacy of adalimumab in pediatric subjects with ulcerative colitis.

CytoMegaloVirus (CMV) infection impairs evolution of Ulcerative Colitis (UC) leading to more severe and resistant to immunosuppressive therapies flare-up. CytoMegaloVirus (CMV) reactivation is assessed by the quantification of the CytoMegaloVirus (CMV) DeoxyriboNucleic Acid (DNA) load by real-time PCR (qPCR) in colonic biopsies; this assay is invasive and costly. The QuantiFERON-CytoMegaloVirus (QF-CMV) assay measures the immune response against CytoMegaloVirus (CMV) in a blood specimen.

Flare-up of ulcerative colitis (UC) is characterized by the inflammation of colon mucosa that requires the use of immunosuppressive therapies. In previous studies, the active role of cytomegalovirus (CMV) has been demonstrated, with a correlation between the cytomegalovirus DNA ((deoxyribonucleic acid) load in the inflamed tissue and the resistance to successive lines of immunosuppressive therapy (Roblin et al., Am J Gastroenterol 2011). The main aim of this monocentric prospective study is to evaluate the DNA viral load by qPCR (Polymerase Chain Reaction) of 3 herpesviruses (Epstein-Barr virus, herpes virus 6 and herpes simplex) together with that of CMV in colonic mucosa depending of the local inflammation (endoscopically normal region, inflamed mucosa or ulcer) in patients suffering of moderate to severe UC flare-up (Mayo score >6 with endoscopic score higher or equal than 2). The viral load will also be correlated to the Mayo endoscopic score and the response to immunosuppressive drugs (steroid and anti-TNF (Tumor Necrosis Factor) monoclonal antibodies).

Defunctioning ileostomy has demonstrated its benefits (rate and seriousness of anastomotic leakage) in cancer for low colorectal and coloanal anastomoses, whereas there are no such good quality evidences in case of ileal pouch-anal anastomosis (IPAA) performed for inflammatory bowel disease (IBD). However, most surgical teams do protect systematically IPAA by an ileostomy. Total proctocolectomy with IPAA is the gold standard for surgical management of ulcerative colitis (UC). This demanding procedure is often performed in 2 or 3 stages, namely subtotal colectomy, completion proctectomy with IPAA and defunctioning ileostomy closure. Subtotal colectomy with double stoma is first performed to allow nutritional support, reduce inflammation and stop immunosuppressive agents. Completion proctectomy with IPAA is then performed on a healthier patient. Hence, the need for a systematic defunctioning ileostomy is questioned. No study addressed specifically the question of completion proctectomy, whereas it concerns 36% to 42% of patients undergoing IPAA. Globally, the overall 6-month morbidity rate is 55% in case of stoma creation vs. 30% otherwise in IPAA. Moreover, defunctioning ileostomy has several drawbacks including an additional surgical procedure (stoma closure), a worse quality of life before closure, and the risk of dehydration that may require readmission. Following stoma closure, the risk of anastomotic leakage is around 4%. Overall, during the stoma period, 8% of patients will require reoperation. Finally, the risk of incisional hernia is 15-20% at the ex-ileostomy site. Therefore, the aim of this trial is to assess the need for a systematic defunctioning ileostomy after completion proctectomy with IPAA.

A double-blind randomized placebo-controlled parallel trial with two intervention arms and two placebo arms and a period of eight intervention weeks to validate the prediction that prebiotics could induce a higher response in mild UC patients with certain fecal microbiome signatures.

The community of microbes living in the gut is called the 'gut microbiome'. Changing this could be an exciting new way of treating people living with ulcerative colitis (UC). UC is a type of inflammatory bowel disease. It affects 4 in every 1000 people in the UK. UC causes severe episodes of inflammation leading to bloody diarrhoea. The gut microbes of people living with UC are different to those in healthy people. This may be part of the reason people with UC have a more inflamed gut. Prebiotics are types of fibre in the diet which help feed the positive microbes in the colon. Eating them can change the make-up and activity of the bugs which live in our gut in a good way. The goal of this clinical trial is to test the effect of a type of prebiotic called a human milk oligosaccharide (HMO) on the symptoms of patients with UC. The main questions it aims to answer are: Can a prebiotic improve symptoms for patients living with UC? Can a prebiotic improve the gut microbiota of people living with UC, and improve markers of inflammation, metabolism and immune function? Patients will take a sachet containing either the prebiotic or a placebo for four weeks, then swap to the other sachet. The trial will be double-blind and randomised. This 'crossover' design means patients act as their own control, which is important in gut microbiology studies. The prebiotic's effect on patient symptoms, metabolism and immune system will be measured. The investigators plan to recruit 44 participants over 18 months. Their urine, blood and stool will be tested. This project will be the first 'bench to bedside' study into the use of prebiotics in IBD. The treatment in this project is rooted in gut model studies. Different prebiotics were tested in the lab to determine which was the best to use for the trial. This 'lab first' approach is a first of its kind.

The purpose of this protocol is to evaluate the efficacy and safety of MK-7240 in participants with moderately to severely active ulcerative colitis. Study 1's primary hypotheses are that at least 1 MK-7240 dose level is superior to Placebo in the proportion of participants achieving clinical remission per Modified Mayo Score at Week 12, and that at least 1 MK-7240 dose level is superior to Placebo in the proportion of participants achieving clinical remission per Modified Mayo Score at week 52. Study 2's primary hypothesis is that at least 1 MK-7240 dose level is superior to Placebo in the proportion of participants achieving clinical remission per Modified Mayo Score at Week 12.

The study is designed to investigate efficacy and safety of CU104 in patients with moderate to severe ulcerative colitis.
