Study Plan
This is an open-label study to evaluate endoscopic changes induced by vedolizumab 300 mg intravenous (IV) infusion using linked color imaging (LCI) over a 46-week treatment period in Japanese patients with moderately to severely active ulcerative colitis (UC). Thirty subjects will be enrolled and relationships between LCI classification and clinical remission by complete Mayo score, LCI classification and mucosal healing by Mayo endoscopic subscore, and LCI classification and histological remission by Nancy histological index are evaluated at Weeks 22 and 54 of treatment. LCI classification is defined by assigning one of the three following categories to the region of colonic mucosa with the strongest degree of inflammation at each endoscopy: A (no redness), B (redness with visible vessels), or C (redness without visible vessels). Similar evaluations will be conducted using LCI index, which is an assessment of the redness of the inflamed mucosa that is defined as the Commission Internationale de l'Eclairage (CIE) a* value of a 40-pixel square area within the captured endoscopic image that displays the region of colonic mucosa with the strongest degree of inflammation at each endoscopy. This study will also evaluate as exploratory outcomes various factors potentially related to changes induced by vedolizumab. To this end, 30 subjects without UC will additionally be enrolled as a reference arm. Subjects without UC will undergo assessments at Week 0 and exit the study immediately without receiving vedolizumab.
The definitions in the study are provided below;
Clinical remission:Complete Mayo score is 2 or less and all subscores are 1 or less
Mucosal healing:Mayo endoscopic subscore is 1 or less
Histologic remission:Nancy histological index is 1 or less
