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.

Detailed Description:
The contribution of the pharmacokinetic studies of monoclonal antibodies (anti-TNF antibodies currently) has assumed increasing importance of its use in clinical practice. Therapeutic algorithms for both Infliximab (IFX) and Adalimumab (ADA) have been published and are used by many expert teams in the event of loss of therapeutic response. Similarly, the concentrations are assuming important in the indication of therapeutic de-escalation. Lastly, the assays may predict medium-term therapeutic response to treatment and thus enable proposal of preventive therapeutic changes (5). The Gemini 1 study (phase 3 vedolizumab vs. placebo in Ulcerative Colitis) showed a correlation between drug levels and clinical response during induction and maintenance therapy. Moreover, in 3.7% of cases, anti-vedolizumab antibodies were reported during the time-course and 1% had samples that were persistently positive. (1). In addition, we have decided to assess the clinical response to VDZ induction at W10 (Week 10), as the Gemini III trial for Crohn Disease (Crohn Disease) have reported, among patients who had experienced previous Tumor Necrosis Factor (TNF) antagonist failure, that 15% of those given vedolizumab versus 12% under placebo were in remission at W6 (P=0.433) whereas a higher proportion of them were in remission (26%) under VDZ when compared with the placebo arm (12%) at week 10. Therefore, in clinically non-responders at W10, an additional dose of 300 mg of VDZ will be infused at W10 and every four weeks.

Arm Intervention/treatment
Experimental: Ulcerative Colitis patients

To 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.

Procedure: Blood sample
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.

Device: Rectosigmoidoscopy
Rectosigmoidoscopy will be performed in each center at time points W0, W10 and W52.




Primary Outcome Measures :
  1. Vedolizumab concentration at week 6 [ Time Frame: Week 6 ]
    Determine the optimal threshold of VDZ serum concentration measured at W6 capable to predict the clinical response at week 10 with VDZ.


Secondary Outcome Measures :
  1. Vedolizumab concentration at week 14 [ Time Frame: Week 14 ]
    Determine the optimal threshold of VDZ serum concentration measured at W14 capable to predict the clinical response at week 52 with VDZ.

  2. vedolizumab concentration and anti-vedolizumab antibodies concentrations at week 2 [ Time Frame: Week 2 ]
    Investigating whether the pharmacokinetic parameters of vedolizumab (serum trough levels concentrations, specific antibody concentrations) measured at W2 are predictive of a clinical response and clinical remission at W10.

  3. vedolizumab concentration and anti-vedolizumab antibodies concentrations at week 14 [ Time Frame: Week 14 ]
    Investigating whether the pharmacokinetic parameters of vedolizumab (serum trough levels concentrations, specific antibody concentrations) measured at W14 are predictive of a clinical response and clinical remission at W52.

  4. Vedolizumab concentration at week 6 and mucosal healing [ Time Frame: Week 6 ]
    Analyzing the value of VDZ trough levels measured at W6 to predict mucosal healing at W10 under induction therapy with VDZ in UC

  5. Vedolizumab concentration at week 14 and mucosal healing [ Time Frame: Week 14 ]
    Analyzing the value of VDZ trough levels measured at W14 to predict mucosal healing at W52 under induction therapy with VDZ in UC

  6. intra and inter-individual heterogeneity of VDZ levels [ Time Frame: Week 52 ]
    Investigating the intra and inter-individual heterogeneity of VDZ levels within the time-course of VDZ therapy, including the induction and maintenance phases.

  7. Proportion of loss of clinical response [ Time Frame: Week 52 ]
    Comparing the proportion of loss of clinical response in responder UC patients as well as in primary non-responders requiring VDZ dose-intensification within one-year of follow-up

  8. Variation of serum VDZ [ Time Frame: Week 52 ]
    Assessing the relationships between the variation of serum VDZ trough levels pre- and post-optimization (delta) and the clinical response in primary non-responder patients requiring additional infusions of VDZ.

  9. vedolizumab concentration and anti-vedolizumab antibodies concentrations [ Time Frame: Week 52 ]
    Comparing the whole and individual pharmacokinetic parameters (vedolizumab concentration and anti-vedolizumab antibodies concentrations) between patients achieving a clinical remission or not at W52
