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. |
- 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.
- 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.
- 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.
- 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.
- 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
- 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
- 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.
- 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
- 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.
- 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

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- - Aged over 18 years
- Men or non-pregnant women
- Patients with a diagnosis of ulcerative colitis who requires to start VDZ
- Moderate to severe active ulcerative colitis defined as a total mayo score ranging from 6 to 12 and endoscopic Mayo score above 1
- UC patients with previous failure with TNF antagonist agents and unacceptable side-effects from steroids, and/or immunosuppressive agents (i.e., azathioprine, 6-mercaptopurine, or methotrexate). In France, VDZ has to be prescribed only in patients in failure or intolerant to anti-TNF.
- Stable doses of oral prednisone (≤30 mg per day) or budesonide (≤9 mg per day), are allowed at stable dose for at least 4 weeks-before inclusion. Concomitant immunosuppressive agents, mesalamine, are allowed at stable dose for at least three months before inclusion. Steroid tapering has to be set up at Week 6 after starting VDZ, according to the European Crohn's and Colitis Organisation (ECCO) recommendations.
- Informed written consent given.
Exclusion Criteria:
- - Existing pregnancy, lactation, or intended pregnancy within the next 15 months
- Minors or History of disease, including mental/emotional disorder that might interfere with their participation in the study

- Inability to fill in the diary cards during the last 7 days before each visit
- Severe Acute UC needed hospitalisation
- Known previous or concurrent malignancy (other than that considered surgically cured, with no evidence for recurrence for 5 years)
- Short bowel syndrome
- Previous treatments with vedolizumab, natalizumab, efalizumab or rituximab.
- Previous treatment with adalimumab within 30 days prior enrollment or infliximab and certolizumab pegol within 60 days before enrollment

- Clostridium difficile superinfection;
- Indeterminate colitis
- Concomitant leukocyte apheresis.
- Any contraindication to vedolizumab therapy
- Patients who denied the protocol, not ability to accept or sign consent of the protocol
- Subject involved in another clinical trial
