Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of this prospective open label study is to assess the ability of vedolizumab to promote clinical, endoscopic and histological remission in patients with active Crohn's disease in an 'early' and a 'late' disease population after 54 weeks of treatment.;Secondary Objective: Measures of clinical disease activity (including clinical response and remission) over the 1 year study period will be described. The mucosal healing capacity of vedolizumab treatment will be observed by assessing the endoscopic and histopathologic response to treatment over the 1 year study period. ;Primary end point(s): The primary endpoint is the proportion of patients with clinical and endoscopic remission at Week 26 and 52-54, defined as CDAI of 150 or lower and SES-CD <4.;Timepoint(s) of evaluation of this end point: Week 26 and week 52 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Proportion of patients with absence of ulcers at Weeks 26 and 52-54 - Proportion of patients with endoscopic response (SES-CD reduction by = 50 %) at Weeks 26 and 52 - Proportion of patients with 25% and 75% reduction of SES-CD at Weeks 26 and 52 - Proportion of patients with clinical response (CDAI decrease of = 70 points from baseline) at all time points - Proportion of patients with clinical remission (CDAI <=150) at all time other points - Proportion of patients with corticosteroid- free clinical remission (CDAI <=150) at all other time points - Proportion of patients with normalized serum CRP at all time points - Proportion of patients with no granulocytes in the biopsies at Weeks 26 and 52. - Proportion of patients with 25%, 50% and 75% reduction in the Geboes histology score at Weeks 26 and 52. - Proportion of patients with sustained clinical response (response at all time points after and on week 10) - Proportion of patients with sustained clinical remission (remission at all time points after week 10) - Proportion of patients with draining fistulas - Proportion of patients that need to be hospitalized - Quality of life measured by IBDQ and Euroquol - Work productivity Index - WHO Disability Index - Serum concentrations of vedolizumab and antibodies to vedolizumab before every infusion ;Timepoint(s) of evaluation of this end point: Week 26 and week 52 | — |
