Summary

Vedolizumab (VDZ) is a monoclonal antibody which has shown its efficacy in Crohn's disease by inducing and maintaining clinical response/remission. The French marketing authorization was obtained for Crohn's disease in patients in failure with anti-TNF (Tumor Necrosis Factor) agents.

For Crohn's disease patients treated with vedolizumab, a strong association between vedolizumab serum levels and clinical response to induction and maintenance was demonstrated by anterior studies.

It could be of paramount interest to early identify Crohn's Disease patients under vedolizumab who will be responders to vedolizumab induction and to identify those who will achieve clinical remission under maintenance therapy with vedolizumab.

Researchers decided to assess the clinical response to vedolizumab induction at week 10. For clinically non-responders at week 10, an additional dose of 300 mg of vedolizumab will be infused at week 10 and then every four weeks.

Interventions

DRUG

Vedolizumab

During each 8 visits (screening, V0, V1, V2, V3, V4, V5, V6) at weeks-1, 0, 2, 6, 10, 14, 22, 54, respectively), the following parameters will be systematically recorded: Crohn's disease Activity Index (CDAI), adverse events. Blood and fecal samples will be systematically collected at weeks 0, 2, 6, 10, 14, 22 and 54 for routine serum ultrasensitive CRP (C-Reactive Protein) and fecal calprotectin assessments and for vedolizumab pharmacokinetic parameters, including the vedolizumab trough levels and the specific anti-Vedolizumab antibodies. In case of loss of response, an additional measurement of serum CRP (C-Reactive Protein), fecal calprotectin and Vedolizumab pharmacologic parameters will be performed.
