Filter by:Butyrate is an important metabolite produced by the gut microbiome and has been shown as a helpful therapy in ulcerative colitis. This is a feasibility study to determine the efficacy of butryate enemas in pediatric ulcerative colitis.
Increased evidence suggests that dopamine acts as an important regulator of immune function. A substantial amount of dopamine exists in the gastrointestinal tract, especially in colonic lumen. Decreased dopamine level has been reported in the colonic mucosa of ulcerative colitis patients. Therefore, the investigators suppose that colonic dopamine could involve in the ulcerative colitis and play an important role. This study aims to explore the role of dopamine in ulcerative colitis and underlying mechanism, which will provide a rationale for diagnosis and treatment of the ulcerative colitis.
The hypothesis of this study is that appropriate time of day of administration of oral, once daily 5-ASA therapy in alignment with the host circadian rhythms will improve subclinical inflammation and microbial structure/function and increase mucosal 5-ASA levels. All subjects will be randomized to once daily 5-ASA medications at two different times of the day: between 06:00 - 10:00 h or 18:00 - 22:00 h. Three disease assessments will performed at: 1) enrollment just before randomization; 2) month 3, at the completion of first arm (Condition 1), and 3) month 6, after completion of the second arm (Condition 2). During these study time points, participants will be asked to complete questionnaires, track their 5-ASA medication usage, provide a stool sample, blood draw, urine test, wear a watch to measure sleep patterns, and complete a flexible sigmoidoscopy.
Endocopic remission rates of moderate to severe ulcerative colitis are low. Biologics including Vedolizumab, infliximab, and adalimumab are effective in induction and maintainence of ulcerative colitis. The role of 5-ASA in promoting a higher rate of endocsopic remission is unclear. We aim to evaluate the efficacy of combination of 5-ASA and biologics in treating ulcerative colitis.
The study objective is aimed to describe all country, site, investigator and patient variables that lead to treatment persistence for at least 12 months among patients with rheumatologic and intestinal chronic inflammatory diseases who were switched to FK adalimumab, in order to develop a model to predict persistence at 12 months.
This prospective observational study is going to develop and validate a prediction model of response to biologic agents and small molecular agents for Korean patients with ulcerative colitis.
This is a randomized, double-blind, placebo-controlled, multicenter Phase 3 study that will enroll approximately 368 subjects aged 18 to 75 years old with Moderately to Severely Active Ulcerative Colitis.
The purpose of this study is to investigate if circadian malalignment (unusual sleeping patterns), such as night shifts (sleeping during the day and being awake during the night time), worsens the inflammation of the gut. We hope to look at patients with Ulcerative Colitis and Healthy Controls.
Purpose: To demonstrate that personalised therapy can be delivered to patients with IBD, by treating patients with an increased risk of poor disease course, defined by a serum protein signature at diagnosis, with a top-down treatment, and that this treatment strategy improves clinical outcomes. Objectives: Primary objective: To assess if a top-down treatment can improve treatment outcomes in IBD patients with a high risk of poor disease course, defined by a serum protein signature at diagnosis. Secondary objective: To assess if a top-down treatment can improve quality of life and health resource allocation in IBD patients with a high risk of poor disease course, defined by a serum protein signature at diagnosis. Study design: A multi-centre, biomarker-stratified open-label controlled trial, where newly diagnosed IBD patients are randomised (1:1) to a group with access to the protein signature or a group without access to the protein signature. Study subjects within the protein signature arm who display a high-risk protein profile, will be treated according to a top-down treatment algorithm (anti-TNF agent with/without an immunomodulatory) and subjects without access to the protein signature will be treated according to current clinical practice. Study population: Newly diagnosed IBD patients. Number of subjects:250 Primary variables: Composite of both corticosteroid-free clinical remission and endoscopic remission at Week 52, defined as below. Surgery because of IBD during follow-up will be defined as treatment failure. Ulcerative colitis; - Clinical remission per patient reported Mayo: A stool frequency subscore (SFS) ≤ 1, and not greater than baseline, and a rectal bleeding subscore (RBS) of 0. - Endoscopic remission: An endoscopic Mayo subscore of 0 (OR in patients without endoscopy at week 52, normalization of f-Calprotectin, defined as < 250μg/g Crohn's disease; - Clinical remission: An average daily Stool Frequency (SF) ≤ 2.8 and not worse than Baseline AND average daily Abdominal Pain (AP) score ≤ 1 and not worse than Baseline. - Endoscopic remission: SES-CD≤2 (OR in patients without endoscopy at week 52, normalization of f-Calprotectin, defined as < 250μg/g.
This study is an open-label study aiming at evaluating the long-term safety and the efficacy profile of ABX464 given once a day (QD) at 25 mg in subjects who have been previously enrolled in the ABX464-102 or ABX464-104 studies (OLE and maintenance studies) and who are willing to continue their treatment. All subjects will receive ABX464 given at 25 mg QD. The enrolment in this long-term study will be based on the endoscopic improvement, the willingness of the subject to carry on his/her participation and also based on investigator's judgement. Subjects will be treated with ABX464 for a maximum period of 54 months. Subjects will be followed up quarterly. After the treatment period, subjects will be followed for 4 additional weeks for safety purposes.
