Active clinical trials for "Colitis, Ulcerative"

Objectives: Primary: The primary study objective is to determine a clinical response as assessed by the Mayo score to low dose PDT in patients with moderate to severe active distal UC. Secondary: The secondary study objectives are to assess the effect on inflammation and the safety and tolerability of low dose PDT in patients with moderate to severe active distal UC. This is a multicenter, open phase II study that will enroll a maximum of 20 eligible patients with moderate to severe active distal UC. The first 10 eligible patients, the first cohort, will receive PDT at a 10 Joule per square centimetre (J/cm2) dose intensity. If no clinical response is observed in the first 7 eligible patients, the study will be stopped due to lack of efficacy. If at least 1 clinical response is observed in the first 7 patients, the first cohort will be completed to a total of 10 eligible patients Trial with medicinal product

The participation in this clinical study will last approximately 21 weeks with a 1 week screening period and a 12 weeks treatment duration. If the study doctor finds, that the patients disease has significantly improved he/she will enter a treatment free follow-up period of 8 weeks. In total the study consists of 5 to 6 clinical visits (V1 - V6) and 1 telephone follow-up call.

Treatment with PPARgamma ligands have been shown to reduces intestinal inflammation in murine models of colitis. The aim of this study was to evaluate the effect of treatment with local PPARgamma ligand (rosiglitazone) in distal ulcerative colitis.The patients are treated with rosiglitazone enema, once a day, for fourteen days. Disease activity was assessed before and after treatment by endoscopical and clinical activity score.

Partial response or loss of response to golimumab is observed in a significant proportion of patients started on golimumab for active ulcerative colitis. The current dosing regimen in European Union is based on patients' body weight as maintenance treatment for patients with ≥ 80 kg is 100 mg q4 weeks and for patients with <80 kg 50 mg q4 weeks. The investigators recent observations in a golimumab pharmacokinetics study of 24 patients however, show large interindividual variations in golimumab trough concentrations. Furthermore, it seems that patients with continuous response have higher golimumab trough levels at several time points during treatment compared to patients who lose response. Higher induction/maintenance dose of golimumab increases golimumab trough levels, therefore it is likely that higher induction/maintenance dose of golimumab would increase efficacy of golimumab treatment.

Brief Summary: This is a randomized, controlled study evaluating metformin tablets administered daily for 8 weeks. The purpose of the study is to evaluate the efficacy and safety of metformin in the treatment of mild to moderately active ulcerative colitis. Disease activity will be measured using Mayo score for ulcerative colitis activity. Calculation of the score requires patients to undergo colonoscopy at the start of the study and at week 8.

This study investigates the effect of individualized monotherapy with Mesalazine (Pentasa Sachet ®) on time to remission in patients with mild to moderate UC in an eHealth setting.

Ulcerative colitis is a chronic idiopathic inflammatory disease of the colon that is characterized by abdominal pain and bloody diarrhea. The pathogenesis of UC involves a complex interplay of genetic factors, immune dysregulation and environmental triggers. Conventional therapies for UC (including 5-aminosalicylates, corticosteroids, azathioprine or 6-mercaptopurine and biologics) focus on altering the immune response by suppression of immune cells. However, the primary pathogenic mechanism underlying UC maybe gut microbiota dysbiosis and a dysfunctional intestinal barrier resulting in an aberrant host immune response. Several studies have shown reduced microbial diversity in UC patients with under representation of anti-inflammatory phyla (Bacteroides and Firmicutes), and a relative increase of pro-inflammatory phyla (Proteobacteria and Actinobacteria). Motivated by this, therapies targeting intestinal dysbiosis (prebiotics, probiotics, synbiotics and fecal microbiota transplant (FMT)) have thus been tried in patients with UC. Though several case series and subsequently four high quality randomized controlled trails have established the efficacy of FMT in induction of remission in active UC, all these studies have used it as an add-on therapy, along with the previously ongoing conventional therapies. The investigators aim to assess the safety and efficacy of FMT as the sole modality for induction of remission in patients with newly diagnosed active UC.

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.

This is a proof of concept, randomized, open label, 2-arm study of OPRX-106 in subjects with active mild to moderate ulcerative colitis. Eligible subjects will be enrolled and randomized to receive 2 mg or 8 mg of OPRX-106 administered orally, once daily for 8 weeks.

The objective of this study is to compare the efficacy of Infliximab-Biosimilar to Infliximab-Innovator and to demonstrate its noninferiority, in patients with ulcerative colitis or Crohn's disease in remission under treatment with infliximab up to 3 months.
