Active clinical trials for "Colitis, Ulcerative"

E.coli Nissle 1917 (Mutaflor®) is equivalent to mesalazine in preventing disease relapse in ulcerative colitis. However, data on ability of E.coli Nissle 1917 (Mutaflor®) to induce remission compared with placebo is limited. Investigators aim to investigate the efficacy of E.coli Nissle 1917 (Mutaflor®) as an add-on treatment to 5-ASA in mild to moderate ulcerative colitis.

The purpose of this study is to determine whether oral etrasimod is a safe and effective treatment for moderately to severely active ulcerative colitis.

This is a Phase 1b, randomized, double-blind-, placebo-controlled, multi-center study to evaluate the safety, tolerability, and PK of GB004 in adult subjects with active ulcerative colitis. Target engagement and effect of GB004 on pharmacodynamic biomarkers will be assessed.

Vedolizumab (VDZ) is a monoclonal antibody that binds to the heterodimer α4β7 integrin and which has shown its efficacy in Ulcerative Colitis (UC) by inducing and maintaining clinical response/remission. The French marketing authorization was obtained for Ulcerative Colitis in patients in failure with anti-Tumor Necrosis Factor (anti-TNF) agents. In the pivotal study, correlation between drug levels and clinical response during induction and maintenance therapy were reported. Moreover, in 3.7% of cases, anti-vedolizumab antibodies were reported during the time-course and 1% had samples that were persistently positive. Up to now, data on the pharmacologic VDZ parameters are scarce and the relationships as well as the predictive value of the measurement of VDZ concentrations and VDZ monoclonal antibodies (mAbs) during the induction and maintenance phases remains unknown. It could be of paramount interest to early identify UC patients under VDZ who will be responders to VDZ induction and to identify those who will achieve clinical remission under maintenance therapy with VDZ.

The purpose of this study is to evaluate vedolizumab pharmacokinetics (PK), safety and tolerability in pediatric participants with moderately to severely active UC or CD.

The purpose of this study was to evaluate efficacy of cobitolimod treatment at different dose levels and frequencies compared to placebo in patients with moderate to severe left-sided ulcerative colitis.

The Mediterranean Diet Pattern (MDP) has been shown to have beneficial effects on the intestinal bacteria and the immune system in diseases like cancer and diabetes. The aim of this study is to determine if a MDP will have an impact on symptoms, intestinal bacteria and the immune system in Ulcerative Colitis (UC). Symptoms, blood and stool will be examined to determine if the MDP results in changes to the intestinal bacteria or immune system.

This is a phase I-II study with the herbal formulation (HF2) for treatment of active ulcerative colitis This will be a two-stage study: Stage 1 will comprise an open label single arm exploratory study of 10 active ulcerative colitis (UC) patients investigating oral HF2 therapy for induction of remission in outpatients with active UC. Active disease is defined as (SCCAI) score ≥5 and a score of ≥2 in the modified Mayo endoscopic sub-score. Clinical remission is defined as a SCCAI score of ≤2 The patients will receive HF2 therapy for 4 weeks. Stage 2: If clinical response (defined as a drop of ≥3 points of the SCCAI score ) is achieved in ≥ 3 patients and no significant safety signals will emerge, the investigators will proceed to a prospective pilot randomized placebo-controlled study. Patients will be randomized into one of two arms: HF2 once daily or placebo formulation (2:1 proportion) for 8 weeks. The primary outcome for stage 2 is a co-primary outcome of clinical response (reduction in SCCAI of ≤3 OR achievement of clinical remission defined as SCCAI ≤2) coupled with an objective evidence of response (Mayo score improvement of ≥1 or 50% FcAL reduction) at week 8. Patients clinically responding at week 8, will be eligible to continue in an 8-weeks extension study to receive either placebo or 1.5gr/day curcumin alone until week 16, as per their original allocation. Exploratory analysis of outcomes for the extension study will include the percentage of patients in clinical remission (SCCAI≤2) and the percentage of patients who maintained clinical response (reduction in SCCAI of ≥3 point compared to week 0).

Ulcerative colitis (UC) is a chronic inflammatory bowel disease associated with recurrent mucosal inflammation. Clinically, the disease is characterized by bloody diarrhea, abdominal pain, and constitutional symptoms such as fever and weight loss. Treatment strategies vary based on disease activity and target various aspects of the inflammatory cascade. Options include: anti-inflammatory drugs (mesalamine), immunosuppressive or modulatory medications (corticosteroids, thiopurines, cyclosporine) and biologic agents (Anti-TNF). Disease severity can be wide ranging, and nearly 25% of UC patients are hospitalized for acute severe disease. Of these patients, 30% will undergo colectomy after the acute episode, a quarter of which will experience post-operative complications. Although there has been great progress in treatment of UC over the past decade, even with the anti-TNF agent infliximab, the one-year remission rate for patients not responding to conservative management is barely 20%. Furthermore, corticosteroids have significant long-term consequences and immune suppressive drugs such as 6-mercaptopurine, azathioprine and infliximab have been associated with serious adverse events including life-threatening infections and lymphomas. With growing evidence that the pathogenesis of UC is multi-factorial and involves a complex interaction of genetic and environmental factors, newer treatment modalities are being evaluated to target the mucosal immune response and mucosal inflammatory regulatory system. Hyperbaric oxygen offers a promising new treatment option since it targets both tissue hypoxia and inflammation. Recent small scales studies evaluating the impact of hyperbaric oxygen treatment in acute ulcerative colitis flares demonstrated improved outcomes. The mechanisms underlying the improvement are not known. In this study, we will treat ulcerative colitis flares with hyperbaric oxygen and measure changes in both markers of tissue hypoxia and inflammation. We hypothesize that hyperbaric oxygen will (a) improve outcomes, and (b) show reductions in markers of both tissue hypoxia and inflammation.

The study will investigate the efficacy and safety of an oral dose of AJM300 960 milligram (mg)/dose administered three times daily for 8 weeks in participants with active ulcerative colitis.
