Value of Pharmacokinetic Assays in the Prediction of Therapeutic Response in Ulcerative Colitis
Vedolizumab (VDZ) is a monoclonal antibody that binds to the heterodimer α4β7 integrin and which has shown its efficacy in Ulcerative Colitis (UC) by inducing and maintaining clinical response/remission. The French marketing authorization was obtained for Ulcerative Colitis in patients in failure with anti-Tumor Necrosis Factor (anti-TNF) agents. In the pivotal study, correlation between drug levels and clinical response during induction and maintenance therapy were reported. Moreover, in 3.7% of cases, anti-vedolizumab antibodies were reported during the time-course and 1% had samples that were persistently positive. Up to now, data on the...
Vedolizumab Post Op Study
This is a pilot study that will determine the endoscopic recurrence of Crohn's disease 12 months after curative, resective ileal or ileocolonic surgery in patients receiving post-operative vedolizumab (Entyvio) or placebo. The investigators hypothesize that the administration of post-operative vedolizumab will decrease the endoscopic recurrence of Crohn's disease.
Vegetarian Diet in Ulcerative Colitis
To determine whether a lacto-ovo vegetarian diet is effective in improving gastrointestinal symptoms, quality-of-life, intestinal inflammation and gut microbiota composition in mild-to-moderate UC compared to a standard omnivorous diet.
