ABTECT - Maintenance
Ulcerative ColitisThis is a multicenter, randomized study to evaluate the long-term efficacy and safety of ABX464 50mg and 25mg administered once daily (QD) as maintenance therapy in subjects with moderately to severely active ulcerative colitis who have inadequate response, no response, a loss of response, or an intolerance to either conventional therapies [corticosteroids, immunosuppressant (i.e. azathioprine, 6-mercaptopurine, methotrexate)] and/or advanced therapies [biologics (TNF inhibitors, anti-integrins, anti-IL-23), and/or S1P receptor modulators, and/or JAK inhibitors]. This study is the maintenance phase of both previous induction studies ABX464-105 and ABX464-106. All eligible subjects who have completed either one of the induction studies above mentioned, will be given the opportunity to take part in the present ABX464-107 maintenance study and will be randomized to either a double blind, placebo-controlled part (Part #1) or allocated to ABX464 50mg or 25mg open label treatment arms (Part #2) depending on their clinical response at the end of induction. This study consists of a 44-week treatment phase and a 28-days follow-up period consisting in the End of Study (EOS) visit.
Study of the Effect of Vedolizumab on Intestinal Microecological Changes and Its Efficacy in the...
Ulcerative ColitisInflammatory 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.
VE202 in Patients With Mild-to-Moderate Ulcerative Colitis
Ulcerative ColitisColitis1 moreA Phase 2 study to evaluate the safety, efficacy, and microbiota changes of VE202 in patients with mild to moderate ulcerative colitis (UC).
CT to Assess the Efficacy and Safety of Adding GMA to Infliximab in Paediatric Patients With Steroid-refractory...
Ulcerative ColitisThe 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.
Investigating the Anti-inflammatory Effects of Frondanol in Adults With Inflammatory Bowel Disease...
Ulcerative Colitis Chronic MildUlcerative Colitis Chronic Moderate1 moreThis 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.

AnemiaIron Deficiency1 moreThe 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.
Long-term Safety and Efficacy Profile of ABX464 in Subjects With Moderate to Severe Active Ulcerative...
Ulcerative ColitisThis 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.
Gluten-free Diet in PSC and IBD
Primary Sclerosing CholangitisUlcerative Colitis3 morePrimary 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.
Stool Transplants to Treat Refractory Clostridium Difficile Colitis
Clostridium Difficile ColitisIt has been shown that restoration of the normal makeup of the bowel bacterial population is the most effective way to treat recurrent colitis due to Clostridium difficile. Restoration of the normal bowel bacterial population is best done by transplanting stool from a healthy donor. The investigators wish to transplant stool from healthy donors to treat recurrent C. difficile colitis by incorporating the stool into capsules that are administered by the oral route.
Standardized Fecal Microbiota Transplantation for Ulcerative Colitis
BacteriaMicrobiota3 moreThe 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).
