Filter by:Ulcerative colitis patients treated with Infliximab (IFX) in deep remission after at least 12 months of treatment will be randomized to continue IFX or to stop IFX and start Azathioprine (AZA). Each patient will be followed for 12 months.
The primary objective is to obtain stool samples from subjects diagnosed with , and displaying signs and/or symptoms of IBD and/or IBS will be evaluated in this study. Eligible subjects require a diagnostic colonoscopy with possible biopsy and clinical evaluation.
This retrospective multi-centric Belgian observational trial will involve all patients who have initiated adalimumab for moderate-to-severe ulcerative colitis prior to September 1st 2015 in a Belgian centre maintaining a prospective log of patients using biological therapy. Only patients fulfilling all Belgian reimbursement criteria for adalimumab will be included, namely having failed mesalamine and steroids or thiopurine analogues for at least 3 months, or being intolerant to this therapy, and showing a total Mayo score of at least 6 with an endoscopic sub-score of at least 2. Both short-term and long-term outcome of adalimumab therapy will be evaluated, focusing on the need and successfulness of adalimumab dose-escalation from 40mg every other week to 40mg every week, and dose de-escalation back to 40mg every other week.
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 objectives of this trial are safety and efficacy (proof-of-concept) of induction of mucosal healing by BI 655130 add-on therapy in patients with mild or moderate ulcerative colitis and persisting endoscopic activity despite pre-existing TNFi treatment. This trial will explore safety and efficacy of a dose of BI 655130 that was modelled to achieve the similar exposures as the highest exposures tested and found safe and tolerable in preceding single and multiple dose studies in healthy subjects, as add-on to pre-existing TNFi (Tumor necrosis factor inhibitor) treatment. Secondary and further objectives include assessment of the pharmacokinetic (PK) profile of BI 655130 and early exploration of specific biomarkers with potential usefulness to predict clinical efficacy or safety outcome or help understand BI 655130's mode of action.
UC is a chronic inflammatory bowel disorder with relapsing and remitting course. The efficacy of mesalazine in preventing relapse in patients with UC is well-known and supported by randomized studies. However, mesalazine can be associated with side-effects. In addition, drug compliance is suboptimal, especially when disease is not active. Curcumin is a natural phytochemical derived from the Indian spice turmeric. It is widely used, has potent anti-inflammatory, anti-oxidant and anti-tumour properties. The aims of this double-blind, placebo-controlled randomized trial is to assess the efficacy of curcumin in the prevention of relapse in patients with ulcerative colitis (UC).
The AIM of this study is to investigate whether the FMT success rate in active UC patients can be increased by intensive donor pre-screening, anaerobic preparation of the FMT and by repeated FMT. The investigators will start a national multi-centre double-blind randomized sham-controlled trial in April 2017 at 6 hospitals in Belgium and 2 in The Netherlands. They will randomly allocate 108 patients with active ulcerative colitis (Mayo score 4-10, endoscopic Mayo score 2 or 3) in a 1:1 ratio, using a pre-established randomization list, to either 'superdonor' faecal microbiota transplantation or autologous fecal microbiota transplantation (=sham). Each patient will receive 4 FMT's. At baseline FMT will be performed during sigmoidoscopy. At week 1, 2 and 3, the FMT will be administered through rectal instillation. Each FMT will be derived from one donor. Donors will be pre-selected based on a species richness and abundance of taxa of interest. The primary outcome will be steroid-free clinical and endoscopic remission at week 8 (Mayo score ≤2, all subscores ≤ 1, and ≥1 point reduction in endoscopy subscore). Fecal, blood and mucosal samples and questionnaires will be collected at different time points. 16S rRNA stool analysis will be performed to assess the microbial changes after FMT.
The research aims to evaluate the efficacy and safety of that mesalazine with hydrocortisone sodium succinate for the induction of clinical remission during a 4-week double-blind treatment period in active UC (define as total Mayo score of greater than or equal to 4 and less than or equal to 10). A total of 528 patients will be randomly divided into three group, one will receive mesalazine 4g with hydrocortisone sodium succinate 100mg enema, and the other two group will respectively to receive mesalazine 4g and hydrocortisone sodium 100mg one times daily for 4 weeks. The end of the study for every patient is the improvement of main symptoms.The primary endpoint is the clinical remission after 2 and 4 weeks double-blind treatment, defined on the basis of a total Mayo score ≤ 2 points, with no subscore > 1 point. The secondary endpoint are endoscopic mucosal healing at week 2 and 4 of double-blind period, defined as an absolute subscore for endoscopy portion of the Mayo score of 0 point and the change from baseline in Quality of Life at week 4 of double-blind period based on the IBDQ.
The etiopathogenesis of ulcerative colitis (UC) is not fully understood. One of the theories of UC pathogenesis represents a pathological response of mucosal immunity to intestinal microbiota. Potential therapeutic procedure how to affect this fact is the faecal microbiota transplantation (FMT). Review of the literature on FMT suggests great potential as the treatment for UC, but two prospective controlled study that has been published yet are inconsistent. The first objective of the project is to compare the administration of FMT enema with mesalazine enema for inducing remission in patients with active left-sided UC in the form of a prospective, randomized, controlled study. The second objective is to observe changes in the intestinal microbiota during and after FMT focusing on bacterial DNA sequencing to identify the bacterial species which are responsible for the effect of the FMT.
This study is designed to evaluate the safety, tolerability, and pharmacokinetics (PK) of single-dose TD-3504 and single dose 15N2-tofacitinib in healthy subjects and subjects with UC. The relative bioavailability of tofacitinib released from TD-3504 compared to co-administered oral heavy-labeled tofacitinib (15N2-tofacitinib) will also be evaluated.
