Active clinical trials for "Colitis"

Inflammatory bowel disease is a group of chronic, non-specific inflammatory diseases of the intestinal tract whose etiology has not yet been fully elucidated, including ulcerative colitis and Crohn's disease. Vedolizumab, a novel biologic agent, is a recombinant humanized monoclonal antibody that specifically antagonizes intestine-selective α4β7 integrins on the surface of leukocyte subsets, thereby preventing migration of leukocyte subsets from the blood to the intestinal mucosa and reducing local inflammation in the gut. In this study the investigators propose to build on an existing cohort and analyse, by means of a multi-omics approach, the baseline gut microbial composition and abundance, intestinal and serum metabolome characteristics of UC patients and their changes during treatment, to predict the functional mechanisms by which these changing characteristics influence the therapeutic response to vindolizumab.

A Phase 2 study to evaluate the safety, efficacy, and microbiota changes of VE202 in patients with mild to moderate ulcerative colitis (UC).

The primary endpoint will be evaluated through the following variables: PUCAI score, IFX levels, and steroid treatment. Clinical response to IFX will be evaluated through the PUCAI score. The response will be considered clinically significant if PUCAI points continue maintained below 30 during the study period. The IFX response will also be determined by IFX serum levels. A therapeutic IFX level, i.e. for achieving an adequate clinical response, is established above 6 μg/mL. Finally, the necessity, or not, of a steroid treatment during the study period will also be indicative of successful efficacy with GMA.

Statins exert numerous pleiotropic effects including anti-inflammatory, antioxidant properties, endothelial function improvement, and immunomodulation independent of their basic lipid-lowering properties.

This is a pilot, prospective, double-blinded, two-arm, randomized controlled trial of the efficacy of Frondanol in comparison to placebo in decreasing bowel inflammation in patients with a clinical diagnosis of inflammatory bowel disease who are in remission and on standard of care treatment.

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.

Primary sclerosing cholangitis (PSC) is a progressive disease of the biliary tree, which represents one of the most frequent indications for orthotopic liver transplantation (OLTx) in developed countries. There are several lines of evidence that dietary gluten/gliadin displays chronic pro-inflammatory, LPS-like properties. Recent evidence demonstrated the protective effect of gluten- free diet (GFD) in autoimmune diseases like type 1 diabetes, irritable bowel syndrome, non-celiac gluten sensitivity and some neurological disorders. This study is intended to explore therapeutic effect of GFD on PSC and IBD in prospective self-controlled mono-centric intervention study. Hypothesis: Avoidance of gluten in diet will reduce progression, symptoms and intestinal inflammation in PSC and UC patients.

The aim of the study is to compare the tolerability and efficacy of Sucrosomial Iron to Oral Iron Therapy in a randomized controlled trial for the treatment of Iron Deficiency Anemia in Ulcerative Colitis patients.

Ulcerative Colitis (UC) is an inflammatory bowel disease that can require the use of anti-TNF alpha therapy. When anti-TNF alpha failed to obtain a clinical response, the use of a new anti-integrin therapy, vedolizumab, can be proposed. The efficacy of vedolizumab has been assessed in a phase 3 study (GEMINI I), with response rates of 41.1% with vedolizumab vs 25.5% with placebo. CytoMegaloVirus (CMV) reactivation has been associated with resistance to steroid and to several lines of immunosuppressive therapy. Antiviral therapy was proven to decrease the tissue viral load and to restore the response to immunosuppressive therapies (up to 80% in small group of patients). A recent meta-analysis supports the use of valganciclovir in case of CytoMegaloVirus (CMV) reactivation in active Ulcerative Colitis (UC). Moreover, a study showed that the risk of CMV reactivation seems to be more important with vedolizumab than with anti TNF, and the risk of colectomy is higher in case of CytoMegaloVirus (CMV) reactivation (p<0.05).

The gut microbiota is considered to constitute a "microbial organ" which has pivotal roles in the intestinal diseases and body's metabolism. Evidence from animal and human studies strongly supports the link between intestinal bacteria and inflammatory bowel diseases (IBD). Dozens of studies reported its efficacy in treatment of severe Clostridium difficile colitis. Preliminary studies using FMT for Ulcerative Colitis (UC), Crohn's diseases, irritable bowel syndrome (IBS) and constipation have also met with some success. This is an initial step into investigating the potential efficacy of standardized fecal bacteriotherapy through mid-gut (at least below duodenal papilla) for UC, the investigators propose to determine the efficiency and safety of FMT in a series of 500 patients with moderate to severe UC (Montreal classification).
