Active clinical trials for "Crohn Disease"

This is an double-blind, single dose, four-period, crossover study in Japanese healthy male volunteers to assess the pharmacokinetics and safety/tolerability of single doses of GSK1605786A. Approximately 24 subjects will receive three treatments of 250, 500, and 1000mg GSK1605786 under fasted conditions or 500mg after food intake plus placebo in a dose ascending crossover design. Serial pharmacokinetic samples will be collected following each dose and safety assessments will be performed. The pharmacokinetics and dose proportionality of GSK1605786 after single oral doses of GSK1605786 at the dose levels of 250mg, 500mg and 1000 mg under fasted conditions will be assessed. In addition, a comparison will be made between the pharmacokinetics of GSK1605786 under fed and fasted conditions.

The proposed study is designed to evaluate Pillcam regimen in Crohn's disease patients, using the PillCam Colon system.

This research will examine the impact of brain activity, cognitive processing immune functioning, and gastrointestinal functioning on depressive symptoms and response to a psychotherapeutic intervention in youths with Inflammatory Bowel Disease (IBD).

The study is being conducted to evaluate the pharmacokinetic parameters (Cmax, Tmax and AUC) of the new delayed release, lowered dose, 40 mg 6MP test formulation as compared to standard 6MP (100 mg Purinethol) in 12 patients with Crohn's Disease. The study is being undertaken to prove that the new test formulation is indeed delayed-release and targeted to the ileum, and that the levels of 6MP in the blood following local absorption are lower than that seen following standard Purinethol dosing. This should result in lower, safer mercaptopurine dosing, allowing for uninterrupted treatment with fewer side effects.

The purpose of this study is to determine whether thiopurine S-methyltransferase (TPMT) genotyping prior to thiopurine use is cost-effective in patients with inflammatory bowel disease (IBD) in need of immune suppression. The study is designed to test the hypothesis that optimization of initial thiopurine dose based on pre-treatment TPMT genotyping will maximize treatment efficacy and minimize adverse drug reactions (ADRs) resulting in reduced costs.

The hypothesis underlying this study is that nasally administered calcitonin will stabilize or improve bone mineral density in young patients with ulcerative colitis or Crohn's disease. Patients who participate will receive either calcitonin or placebo and will have their bone mineral density measured at the start, at nine months, and at 18 months of study. Participants will also receive age appropriate doses of vitamin D and calcium supplements. Other serological measures of vitamin D status will be obtained every 3 months during the study.

FOS improve gut colonization by Faecalibacterium prausnitzii in patients with Crohn's disease

Increased Intestinal Permeability is detectable in clinically active Crohn's disease, in stable Crohn's disease and is predictive of clinical relapse. Maintenance of the epithelial barrier integrity is therefore essential for intestinal homeostasis. Vitamin D may have a critical role in improving barrier function.

The daily requirement of threonine, an essential amino acid, will be evaluated in healthy adult males and in adult males with Crohn's Disease or ulcerative colitis using the indicator amino acid oxidation (IAAO) method. Participants will consume specially formulated diets with varying levels of threonine.

Current evidence suggests that the gut microbiota and dietary influences are as important as genetics in the aetiology of Crohn's disease (CD). We have recently shown that disease improvement, following treatment with Exclusive Enteral Nutrition (EEN), coincided with changes in the gut microbiota. The main purposes of this study are: a) to explore whether the gut microbiota changes we observed in this previous study in children with CD during EEN are disease specific or not, and b) to develop a novel food-based diet (Crohn's Disease TReatment-with-EATing/CD-TREAT diet) which will induce changes to the metabolic activity and bacterial composition of the gut microbiota of healthy people, similar to those seen on EEN, the first-line treatment for active paediatric CD. This study will produce high quality scientific evidence to move the CD-TREAT diet towards a preliminary clinical trial in patients with CD which is currently inappropriate and unethical to carry out in people with active CD undertaking contemporary medical treatment.
