Proportion of Participants Achieving Endoscopic Improvement Assessed by Mayo Component Sub-scoresWeek 52 and Week 104
Proportion of Participants Achieving Clinical Response Assessed by Mayo Component Sub-scoresWeek 52 and Week 104
Proportion of Participants Achieving Clinical Remission Assessed by Mayo Component Sub-scoresWeek 52 and Week 104
Proportion of Participants Achieving Clinical Remission at Weeks 52 and 104 Among Participants Achieving Clinical Remission at Study EntryWeek 52 and Week 104
Change From Baseline in Partial Mayo ScoreBaseline, Week 52, Week 104, Week 156, Week 208 and Week 260

The partial Mayo score is a tool designed to measure disease activity for ulcerative colitis. Scoring ranges from 0 to 9 points and consists of 3 non-invasive components (rectal bleeding, stool frequency, and physicians global assessment), each graded 0 to 3 (0 = normal, 1 = mild, 2 = moderate, 3 = severe) with higher score indicating more severe disease.

Change From Baseline in the Total Mayo ScoreBaseline, Week 52, and Week 104

The total Mayo score is a tool designed to measure disease activity for ulcerative colitis. Scoring ranges from 0 to 12 points and consists of 4 components (endoscopic score, rectal bleeding, stool frequency, and physicians global assessment), each graded 0 to 3 (0 = normal, 1 = mild, 2 = moderate, 3 = severe) with higher score indicating more severe disease.
