Brief Summary
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 pharmacologic VDZ parameters are scarce and the relationships as well as the predictive value of the measurement of VDZ concentrations and VDZ monoclonal antibodies (mAbs) during the induction and maintenance phases remains unknown. It could be of paramount interest to early identify UC patients under VDZ who will be responders to VDZ induction and to identify those who will achieve clinical remission under maintenance therapy with VDZ.

Study Arms (1)
Ulcerative Colitis patients
EXPERIMENTALTo determine if the best cut-off points of vedolizumab (VDZ) trough levels measured at W6 capable to identify UC patients who will achieve a clinical response at week 10 with VDZ and also the best cut-off points of VDZ trough levels measured at W14 capable to identify UC patients who will achieve a clinical remission to maintenance therapy with VDZ : Blood samples will be systematically collected at W0, W2, W6, W14 and W52 for vedolizumab pharmacokinetic parameters, including the vedolizumab trough levels and the specific anti-vedolizumab antibody. A supplementary blood sample will be collected at W10 which is the point where a significant greater number of patients were in remission. Rectosigmoidoscopy will be performed in each center at time points W0, W10 and W52, to evaluate treatment efficacy. In cases of loss of response, rectosigmoidoscopy will be performed before and four weeks after optimization.
