Active clinical trials for "Colitis, Ulcerative"

The purpose of this survey is to evaluate the long-term safety and effectiveness of vedolizumab for intravenous (IV) infusion 300 milligrams (mg) in ulcerative colitis (UC) patients in the routine clinical setting.

This is a Phase 2, multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of 2 doses of GED-0507-34-Levo in subjects with active, mild-to-moderate UC.

The purpose of this study is to allow subjects completing study LYC-30937-2001 the opportunity to receive LYC-30937-EC 25 mg.

Objectives: To examine the effect of accelerated infliximab induction in children with moderate to severe UC. Design: A multi-center, prospective, randomized, open label study. Setting: Pediatric gastroenterology centers. Participants: Children 6 year to 17 years (Overall, 84 patients) with moderate to severe UC who are corticosteroid dependent/resistant thus planned to receive infliximab induction. Intervention: Group 1 (intervention) will receive an accelerated induction at 0,1,3 weeks (5 mg/kg) and then at week 7,11,15. Group 2 (standard) will receive a per protocol induction at 0,2,6 weeks (5 mg/kg) and then at week 14. Drug levels will be obtained prior to each infusion in each group (up to week 20). Further maintenance will be planned according to drug levels at weeks 15 and 14, respectively. Follow-up will continue without further interventions till 52 weeks following induction. Main outcome measure: Clinical remission, on infliximab at week 20. Secondary outcome measures: 1. Colectomy free rates at week 20 and 52. 2. Clinical remission on infliximab at week 52. 3. Drug levels and anti-drug antibodies prior to last study infusion. 4. Anthropometric and laboratory measures including calprotectin at the end of induction, week 20 and week 52 5. Changes in fecal microbiome, virome and bile acids content. Sample size: In order to demonstrate 30% difference in clinical remission rate between groups is significant, we will need to study 36 children in each group to be able to reject the null hypothesis that the failure rates between the groups are equal with probability (power) of 80% and a type I error probability of 0.05.

Ulcerative colitis (UC) is an entity of complex etiology where environmental, genetic and intestinal microflora-related factors trigger and perpetuate a chronic inflammation of the gastrointestinal tract. It is suspected that an alteration in primary intestinal microbial colonization (dysbiosis) could trigger, or at least contribute to, said oversized immune response. The hypothesis is that the administration of a series of fibers, could improve the bacterial diversity and repair the dysbiosis that has been seen in patients affected by ulcerative colitis, improving the clinical evolution of it. The primary objective of the present study is to know the impact on the microbiota of patients with UC in remission derived from the administration of dietary fibers. The RETOS study is a pilot project in which a population of patients with UC is tested for the effect on the composition of the microbiota that would have the administration of various combinations of fibers, in addition to the tolerability and acceptance by the patient. The clinical applicability derived from this intervention would be to improve the diversity of intestinal flora of patients with ulcerative colitis.

The purpose of this study is to evaluate the efficacy of SHP647 in inducing remission, based on composite score of participant-reported symptoms and centrally read endoscopy, in participants with moderate to severe ulcerative colitis (UC).

This study is a follow up study for subjects with Ulcerative Colitis (UC) in stable remission designed to evaluate flexible dosing of CP-690,550.

A study with an 8 week open label phase study followed by a year long placebo controlled maintenance phase in subjects with active mild to moderate ulcerative colitis (UC), with a modified Mayo Score 4-10 and an endoscopy subscore of 2-3, taking mesalamine (or equivalent) as a concomitant medication. Subjects are required to be in clinical remission or clinical response to enter the year long maintenance phase. This study will help evaluate if HMPL-004 is effective in subjects maintaining clinical remission following successful induction therapy achieving clinical remission or clinical response.

This is an open label exploratory study to investigate the safety of 400 milligram (mg ) twice a day (b.i.d.) GSK2586184 in patients with moderate to severe, active ulcerative colitis (UC). Study medication will be administered orally (as tablets), twice daily, for up to 8 weeks (56 days). Study medication will be taken with food. Each subject will have 6 out-patient visits: Screening (Day -30 to -1); Baseline and Start of treatment (Day 1); Week 2 (Day 14); Week 4 (Day 28); Week 8 (Day 56); and Follow-up (Week 12; Day 84). Visit windows for weeks 2, 4 and 8 will be + 2 days. The primary objective of this study is to assess the safety and tolerability of GSK2586184. The primary endpoints to measure safety are laboratory tests (including haematology, clinical chemistry and serum creatinine), vital signs, 12-lead electrocardiogram (ECG), physical examination, and adverse event reporting. These are standard measurements to evaluate safety.

The investigators are conducting an open-label study of fecal microbiota transplantation (FMT) for adult patients with mildly-moderately active ulcerative colitis. In this pilot study the investigators will evaluate the feasibility, safety, and tolerability of a single application of FMT delivered colonoscopically. The investigators will also characterize the impact of FMT on the microbiota of the recipient and determine if it correlates with the microbiota from the FMT donor.
