Filter by:This study aims to characterize the Portuguese population of patients with moderate-to-severe UC receiving advanced therapies, by describing clinical and sociodemographic characteristics, and remission outcomes . The clinical, biochemical, endoscopic, and histological outcomes will also be described, as well as frequency of selected EIM, comorbidities and the uptake of preventive care measures and hospitalizations .
This is a Phase 2, multi center, randomized, placebo controlled parallel group study to evaluate the clinical efficacy and safety of LC51 0255 in subjects with moderately to severely active ulcerative colitis
Inflammatory Bowel Diseases are incurable, life-long conditions that significantly impact a patient's quality of life. Crohn's Disease and ulcerative colitis are the most prevalent inflammatory bowel diseases in the United States; both are characterized by chronic, relapsing inflammation of the intestinal tract, which manifests as symptoms of diarrhea, fecal urgency, fecal incontinence, fever, fatigue, abdominal pain and cramping. These severely debilitating periods of illness or "flare" alternate with times of remission when patients have few or no symptoms, and feel healthy. Despite periodic respite, many patients with IBD experience severe stress and anxiety even when they are well, because of the likely occurrence of episodes of disease in their future. This is exacerbated by the unpredictable frequency and inconsistent duration of flares that may last as long as several weeks or months. The goal for this study is to use non-invasive monitoring techniques to identify biomarkers that emerge, or change predictably, when a patient begins to relapse from remission to enter a period of disease - to find the earliest signs of an active flare. If the investigators identify a pattern of biomarkers that could alert a patient and their clinician to a flare as soon as it begins, it may be possible to intervene before symptoms present by changing medication and/or diet and lifestyle to lessen the severity of the disease flare. The biomarker fingerprint may also reveal new targets for therapeutics that could control IBD.
Ulcerative colitis (UC) is a chronic inflammatory bowel disease which often follows a relapsing/remitting course. Anti-TNF therapies are proven to be effective in UC and studies indicate that having adequate drug levels correlate with improved patient outcomes. It is unknown, however, if a high burden of disease at baseline impacts drug utilization or loss. In this study, we investigate whether measures of high burden of disease (fecal calprotectin, bowel ultrasound, and colonoscopy) at baseline predicts low drug levels after standard anti-TNF induction therapy.
The purpose of this study is to evaluate the efficacy and safety of itacitinib in participants with moderate to severe ulcerative colitis (UC).
Research of fecal microflora and dysbiosis status in ulcerative colitis (UC) has shown its influential role on the disease pathogenesis. Vedolizumab, a humanized monoclonal antibody blocking the migration of leukocytes into inflamed intestinal tissue, has been shown to achieve remission in about half of active UC patients. Dietary intervention in UC patients has not been adequately studied. There is a significant clinical gap to achieve a higher efficacy and better clinical outcomes on the treatment of active UC patients. This study proposes to assess the integrated effect of normalization of intestinal dysbiosis through a structured semi-vegetarian dietary intervention in active UC patients who will also be under the standard of care medical therapy (vedolizumab). Significance of investigation for innovation: The pathogenesis of UC has been found to be multi-factorial, including host genetics and dysregulated inflammatory response, and recent research has shown the influential role of gut environmental factors - dysbiosis which has been found the key feature of UC. Vedolizumab has been shown effective (e.g. 47% clinical response rate vs. 25% in placebo group) and is part of the current standard of care treatment in UC. With the observation of drastic increase of IBD patients in Asia, in which has historically low incidence of IBD, it is generally accepted that the westernized diet and urbanization of life style play an important role in IBD pathogenesis. Enteral nutritional therapy has been demonstrated effective in pediatric Crohn's disease (CD) patients; however, the application to adult IBD patients has not been widely accepted partly because of the compliance issue. In addition, unlike CD, neither enteral nutrition nor non-enteral nutrition in patients with active UC has been adequately studied. Therefore, this study proposes a novel approach to assess the integrated effect of a structured dietary intervention in active UC patients who will also be under the current standard of care medical therapy (vedolizumab). After this study achieves the proposed primary or secondary outcome, it will further support the hypothesized synergistic interactive therapeutic effect between the normalization of dysbiosis in the intestine (through dietary intervention) and anti-inflammatory biologics (vedolizumab).
The purpose of this research study is to determine whether starting the drug vedolizumab earlier than its FDA approved use can lead to better control of UC then using older drugs that we have historically used to treat UC. Vedolizumab is FDA-approved to be used after initial Corticosteroid treatments have failed or other UC treatments have failed. We will study if using vedolizumab as an early treatment for your UC will allow you to get off corticosteroids and prevent UC from worsening and requiring surgery. Vedolizumab is given intravenously initially every 2 weeks and then every 8 weeks.
To examine whether a temporary three month increase in adalimumab dosing will prevent relapse in patients with inflammatory bowel disease in clinical remission who have elevated calprotectin.
The research aim to find out whether berberine can reduce the annual recurrence rate of ulcerative colitis in remission. A total of 238 patients with ulcerative colitis in remission will be randomly divided into two groups.One will receive regular treatment,and the other group will receive extra oral berberine 300 mg three times daily for a year. The end of the study for every patient is disease recurrence(Mayo Clinic score of 3 points or more ). The primary analysis is annual recurrence rate, and both endoscopy and Mayo Clinic disease activity index scores at the baseline and final assessments.
The purpose of this study is to assess the bioavailability and pharmacokinetics (PK) of multiple doses of vedolizumab subcutaneous (SC) compared to vedolizumab intravenous (IV).
