Active clinical trials for "Colitis"

The ReDUCE Trial is a multinational single-blinded randomized controlled trial in mild to moderate flare of Ulcerative colitis (UC) disease patients. The purpose of the study is to validate the clinical efficacy of the UCED (Ulcerative colitis Exclusion Diet) with partial enteral nutrition (PEN) using a novel formula. The investigators anticipate that adding a novel specifically designed dietary intervention in addition to drug will lead to superior remission and mucosal healing via changes in the microbiome.

Chronic intestinal hypoxia and accompanying mucosal inflammation is a hallmark of ulcerative colitis (UC). Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen under increased atmospheric pressure to increase tissue oxygenation. Two small prospective randomized controlled trials have demonstrated that the delivery of HBOT to UC patients hospitalized for acute moderate to severe flares results in improved remission rates and avoidance of in-hospital progression to biologics, small molecules, or colectomy. In this larger trial the study aims to confirm the treatment benefits of HBOT for hospitalized UC patients and study the immune-microbe mechanisms underpinning treatment response.

The goal of this study is to establish a prospective observational cohort of adult patients with microscopic colitis and collect clinical information and specimens over the course of their treatment. This information will be used in order to establish a patient registry with detailed clinical data and a specimen repository for future research as well as to specifically identify genetic and molecular characteristics associated with microscopic colitis.

TARGET-IBD is a 5-year, longitudinal, observational study of adult and pediatric patients (age 2 and above) being managed for Inflammatory Bowel Disease (IBD) in usual clinical practice. TARGET-IBD will create a research registry of patients with IBD within academic and community real-world practices in order to assess the safety and effectiveness of current and future therapies.

FRESCO is a randomized, longitudinal, prospective, three arm, multicentre, double blind study to determine safety and efficacy of repeated faecal microbiota transplantation (FMT) or faecal microbiota filtrate transplantation (FMFT) compared to placebo using oral, frozen capsules in 174 randomized patients with mild to moderate active Ulcerative Colitis.

A pilot study investigating if orally administrated faecal microbiota transplantation capsules have the potential to treat active microscopic colitis.

Ulcerative Colitis (UC) is a chronic Inflammatory Bowel Disease (IBD) characterized by a multifactorial etiology, a variable involvement of large bowel, and a relapsing-remitting course. In order to keep the disease in a "quiescent" status and to prevent relapses, a significative percentage of UC patients will remain on long-term drug therapy. However, long-term immunosuppressant therapy is not free of risks and complications: in fact, these therapies have an impact on both healthcare system resources and patients' quality of life; more, there are even concerns regarding the side effects of long-term immunosuppressant therapy. Over the past 20 years, a considerable amount of evidence was produced to support the immunomodulatory role of the appendix in the development and course of UC: there is a strong inverse relationship between previous appendectomy and development of the UC. One of the proposed theories to justify this link is that the appendix could act as a reservoir for commensal bacteria that can be secreted into the colon, affecting its microbiome and immunological response; another theory describes the appendix as the "priming site" for the cytokine production and the immunological cascade that may trigger inflammation in colon and rectum. The idea of this study moves from these assumptions: the investigators aim to evaluate the impact of appendectomy in patients with UC who are candidates to the treatment with biologics (Anti TNF-a), because of conventional therapies failure. To further reduce any ethical problems and significantly lower any surgical morbidity, investigators will restrict the study population to only patients with active left-sided colitis, so that the surgery for appendectomy will take place on a non-inflamed cecum. By undertaking this study, the investigators hope to a) learn more about the role of appendix and the impact of appendectomy in the clinical history of Ulcerative Colitis; b) demonstrate that laparoscopic appendectomy, a relatively simple surgical procedure that can also be performed in day-surgery with a very low expected complication rate, is a treatment that is superior to biological therapy, avoiding patients starting a chronic, long-lasting therapy, with the consequent risk of immunosuppression, and with possible higher costs for the health system in the long term.

This is a prospective observational study using data from an existing, ongoing National Swedish registry (SWIBREG). This study is designed to assess the effectiveness and treatment adherence of tofacitinib on clinical disease activity parameters in patients with ulcerative colitis in Swedish clinical practice. The study will also assess treatment adherence of tofacitinib using the Swedish Prescribed Drug Register.

The main aim of this study is to learn about the effect of treatment with vedolizumab IV (vedolizumab) together with tofacitinib in adults with moderate and severe ulcerative colitis (UC). Another aim is to learn about treatment with Vedolizumab alone after the double treatment. All participants will receive vedolizumab together with tofacitinib for 8 weeks and will be checked for response. Participants who show a response to the treatment after 8 weeks will be treated with vedolizumab alone for an additional 44 weeks. Each participant will be followed up for at least 26 weeks after the last dose of vedolizumab.

The main aim of this study is to learn how the body of a child or teenager with moderately to severely active ulcerative colitis (UC) or Crohn's disease (CD) processes vedolizumab (pharmacokinetics) given just under the skin subcutaneously (SC). The participants will be treated with vedolizumab for up to 34 weeks. During the study, participants will visit their study clinic several times.
