Active clinical trials for "Colitis"

This is a multi-center study in Ireland and United Kingdom to determine the effects, safety and tolerability of a drug called CyCol™ in improving mild to moderate ulcerative colitis (UC). Informed consent will be obtained and following confirmation of eligibility and disease assessment, study participants will be randomised (allocated by chance) to take either CyCol™, or placebo, orally once every day for four weeks. Study visit assessments will include blood and stool tests, physical examinations and flexible sigmoidoscopies (inspection of the bowel wall using a flexible camera). Half the participants will receive CyCol™ and half will receive placebo. At the end of treatment (4 weeks) study participants will be reassessed again and the findings in those who received CyCol™ will be compared with those who received placebo. Any side effects experienced during the study and the safety of treatment with CyCol™ will also be evaluated.

The purpose of this study is to evaluate the safety and tolerability of visilizumab in patients with severe ulcerative colitis that has failed to respond to steroid therapy. What is visilizumab? Visilizumab is an antibody designed to reduce inflammation. Antibodies are proteins that are normally made by the immune system to help defend the body from infections and other foreign substances. Visilizumab is thought to selectively affect the immune system to decrease inflammation and, in doing so, it may prevent damage to the intestine caused by ulcerative colitis. Who can participate in this study? The target population for this study is adults with severe ulcerative colitis that has resisted intravenous (IV) steroids. This study is open to patients with the following characteristics: 16-70 year olds A diagnosis of ulcerative colitis verified by colonoscopy or barium enema performed within 36 months prior to study entry Active disease despite ongoing treatment with steroids How is this study conducted? Eligible participants will be administered visilizumab as one daily injection on two consecutive days. All medication and study-related care, except for the costs of in-patient hospitalization, are provided to qualified participants at no cost. This includes all visits, examinations and laboratory work. How does one get more information? This study is currently enrolling patients at hospitals and clinics in North America and Europe.

To establish the efficacy and safety of a new tablet formulation and dosing regimen of balsalazide disodium dosed twice daily in achieving clinical improvement in subjects with mildly to moderately active ulcerative colitis after 6 weeks of therapy.

Approximately 300 patients will be entered into this study taking place throughout the United States, Canada and the United Kingdom. This study aims to determine if an investigational drug is safe and effective for treating the symptoms of C. difficile-associated diarrhea and lowering the risk of repeat episodes of diarrhea. The investigational drug will be evaluated in comparison to current standard antibiotic treatment, so all patients will receive active medication. All study-related care is provided including doctor visits, physical exams, laboratory tests and study medication. Total length of participation is approximately 10 weeks.

Investigators propose to validate efficacy and safety of the detection of DEFA5 in the diagnosis of the colonic IBD using longitudinal vs. cross-sectional studies of known patient clinical data to correlate with their endoscopy biopsy data. 30% of colonic IBD patients cannot be accurately diagnosed (CC vs. UC) in a timely manner even when a state-of-the-art classification system of combined clinical, endoscopic, radiologic and histologic tools are used. When the diagnostic classification for these two diseases is inconclusive, the condition is termed indeterminate colitis (IC). Here, the central medical challenge is the discrimination of IBD into the specific subtypes with high accuracy, as it greatly effects surgical care of patients. Diagnostic accuracy of IC into either authentic UC or CC is of utmost importance when determining a patient's candidacy for RPC-IPAA surgery, the standard curative surgical procedure for UC. Further, incorrect diagnosis and treatment carry potential morbidity from inappropriate and unnecessary surgery and costs. The success outcomes of RPC-IPAA surgery and convalescence depend on correct diagnosis. To address IBD diagnosis ambiguity and delays in IBD clinical settings, investigators developed a proteomic signature to discriminate between UC and CC patients that also will predict the outcome of IC patients for their eventual progress to either UC or CC. Our published data has shown robust evidence supporting presence of human alpha-defensin 5 (DEFA5) in areas of the colon mucosa with aberrant expression of apparent Paneth cell-like cells (PCLCs) or crypt cell-like cells (CCLCs), which identifies an area of colonic ileal metaplasia, consistent with the diagnosis of CC. DEFA5 bioassay discriminated CC and UC in a cohort of all IC patients with accuracy. A fit logistic model with group CC and UC as the outcome and the DEFA5 as independent variable differentiator with a positive predictive value of 96%. These findings were obtained solely from colectomy specimens for both the discovery and validation analyses. Investigators believe that use of endoscopy biopsies would be indifferent, which is the purpose of this prospective patient centered clinical study. Investigators propose to demonstrate that UC and CC, the two unsolved medical subtypes of pathology with no drugs for a cure, can accurately be distinguished molecularly by examining CCLCs-secreted DEFA5 in colonic endoscopy biopsies instantly. Our proposal is highly innovative, as it highlights the robustness of DEFA5 and its clinical relevance to IBD is both in science and the anticipated impact, as investigators seek to better understand difficulty to determine 'subtypes" and translate that to improve diagnosis, treatment, clinical outcomes, and quality of life for patients and the realm of clinical care. DEFA5 immunoreactivity in colonic endoscopy biopsies could be a rapid potential diagnostic signature to resolve IC into authentic UC and CC with a first clinic endoscopy biopsy. IC is likely to be eliminated for good.

Inflammatory bowel disease is a condition caused by gastrointestinal immune system dysregulation and affected by both genetic and environmental factors. Differences in intestinal bacteria exist between IBD patients and healthy controls, but the role of intestinal bacteria in the development and treatment of IBD remains largely unknown. Fecal microbiota transplantation (FMT) is the transfer of gastrointestinal bacteria from a healthy donor to a patient with altered microbial diversity with the intent of restoring a normal bacterial balance. Most studies focus on its use in treating Clostridium difficile (CDI), an infection characterized by dysbiosis. Given the role of dysbiosis in IBD, the investigators hypothesize that FMT may be beneficial in IBD. The purpose of this study is to prospectively examine the safety of FMT in the management of ulcerative colitis (UC).

The purpose of this trial is to investigate the efficacy of mesalamine for the induction of clinical and endoscopic remission in subjects with active, mild to moderate UC. Subject will receive 4 g extended release granules (sachet) once daily.

IBD98-M-2002 is a phase 2a , Randomized, Double blind, Placebo-controlled of IBD98-M Delayed Release capsules in subjects with Mild to Moderately Ulcerative Colitis to investigate the clinical efficacy of IBD98-M delayed release capsules (in a fixed combination) over a 6-week treatment period and 2 weeks follow up.

This clinical trial is the first-in-human study of BBT-401-1S. The purpose of this phase 1 study is to assess the safety and tolerability of single and multiple ascending oral doses of BBT-401-1S in healthy adult subjects.

The purpose of this study is to investigate the efficacy and safety of 4-week double-blind treatment with PENTASA enema compared with placebo enema in Chinese patients with mild to moderate active left-sided ulcerative colitis, followed by a maximal 28-week open-label extension phase with PENTASA enema and/or PENTASA tablets.
