Study design details

Main study objective

The primary objective of this study is to describe the percentage of patients treated with vedolizumab experiencing resolution of EIMs within 6 months post-treatment initiation.

Outcomes

Primary outcome measure includes the demographic and clinical characteristics, percentage of patients with resolution of EIMs 6 month’s post-treatment initiation with vedolizumab. The secondary outcome includes clinical effectiveness at 14 weeks post induction, Month 6 and 12 post treatment initiation, change in physician assessment, disappearance of inflammatory lesions, change in level of C-reactive protein and faecal calprotectin, percentage of patients with EIMs resolution at Month 12, persistence rate at Month 12, time to treatment discontinuation, and safety events.

Data analysis plan

Continuous variables will be described with number of patients with valid or missing observations, mean, standard deviation (SD), median, 25 and 75 percentiles (P25 and P75 respectively), minimum and maximum.
