Active clinical trials for "Colitis, Ulcerative"

The purpose of this study is to explore the safety, efficacy, effects on quality of life (QOL), and biomarker response of ozanimod in participants with moderate to severely active ulcerative colitis (UC) in clinical practice.

A Clinical Study on the Safety and Effectiveness of Targeting CD7 Chimeric Antigen Receptor T Cells in the Treatment of Autoimmune Diseases

The purpose of this study is to determine the safety, efficacy, and pharmacokinetics (PK) of etrasimod for the treatment of moderately to severely active ulcerative colitis in adolescents (≥ 12 years up to < 18 years of age). Participants who will complete the total 52-week treatment period will have the opportunity to continue in a Long-Term Extension (LTE) Period of up to 4 years (5 years after study enrollment), or until marketing authorization is obtained in the participant's country, whichever comes first.

SPH3127-US-01 is a multi-center, randomized, double-blind, placebo-controlled study to evaluate the safety, pharmacokinetics, and preliminary efficacy of SPH3127 for the treatment of mild-to-moderate ulcerative colitis.

The purpose of the study is to evaluate the efficacy of cobitolimod treatment compared to placebo in inducing clinical remission, in participants with moderate to severe active left-sided UC and to evaluate the efficacy of cobitolimod maintenance treatment compared to placebo in inducing or maintaining clinical remission at week 52, in participants with clinical response at week 6 after induction treatment with cobitolimod.

To preliminarily evaluate the clinical efficacy of the renin inhibitor SPH3127 Tablets in patients with mild to moderate ulcerative colitis with placebo as a control and determine the recommended dose.

Several oral mesalazine (5-ASA) formulations exist, but the regimes require several tablets per day. Such regimens are not ideal and can interfere with normal daily activities of patients. Non-adherence has been associated with an increase in the risk of relapse and worse disease course; leading to a decrease in quality of life, an increase in societal and personal costs, and worst case increases the risk of colorectal cancer. Recently, a new formula for 5-ASA has been approved by the Danish Medicine Agency, with a single tablet regime per day. Primary purpose: • To investigate whether a simplified treatment regimen for 5- ASA (1600 mg as one tablet per day [intervention]) improves adherence with preserved remission rates compared to conventional therapy. Secondary purposes: Compare levels of endoscopic, mucosal and histological inflammation in predicting risk of relapse between the intervention group and the conventional therapy group. Investigate whether a simplified treatment regimen improves the disease course compared to the conventional therapy. To assess the correlation between different endpoints and the disease courses, with the use of clinical, endoscopic, histological, self-reported and biochemical markers. Improve, correlate and assess patient-reported outcomes in a prospective manner. To establish a biobank of cases with quiescent/mild ulcerative colitis (UC) for identification of future biomarkers.

Fecal microbiota transplantation (FMT) is a strategy that infuses a fecal suspension containing a healthy donor's microbiota into a patient's gut to restore his/her intestinal microbiome. Fecal microbiota transplantation has been used for several disease，but the efficacy of ulcerative colitis(UC) by fecal microbiota transplantation needs to be further explored.The investigators propose to determine the efficiency and safety of FMT in patients with ulcerative colitis(UC).

Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) that results from immune dysregulation. Arguably, the development of Tumor Necrosis Factor (TNF) antagonists (including infliximab, adalimumab and golimumab) revolutionized the management of immune-mediated chronic diseases in the past two decades. However, about one third of patients will not respond to a first anti-TNF treatment and 10% to 30% will loose response to anti-TNF during the follow-up. Historically, a switch between anti-TNF was performed to recapture remission and response to anti-TNF. Recently, a new biologic therapy blocking another target has been approved and is now reimbursed during ulcerative colitis, namely vedolizumab. Vedolizumab is an anti-integrin agent avoiding the recruitment of lymphocytes specifically in inflamed gut tissue. Emerging data suggest that a switch of therapeutic class (meaning a change of biologic target with Non-TNF-targeted biologic) in case of clinical failure or insufficient response to anti-TNF may be the best choice. This idea of a switch out of the anti-TNF class is also supported by data on drug monitoring that may help physician decision making in case of loss of response. However, no trial is currently available and ongoing to assess the best therapeutic strategy. The aim of the proposed study is to assess the best biological based strategy in patient losing response to a first subcutaneous anti-TNF (golimumab and/or adalimumab).

For the last years the aim of the management of ulcerative colitis (UC) has become more ambitious including not only clinical remission but also the achievement of biological remission, endoscopic and histological healing, which are associated with less flares, hospitalizations and surgeries. About 50% of the patients with UC followed in routine are treated by 5-aminosalicylate acid (5-ASA) (oral and/or topical). The aim of the study is to describe the different levels of remission (clinical, endoscopic, histological) in UC patients treated only by 5-ASA, that report to be in clinical remission during a routine follow-up visit. The factors associated with different levels of remission (demographic, 5-ASA regimen, biologic, endoscopic, histologic) will be studied. Adherence and quality of life will be examined through patient questionnaires.
