Endoscopic remission is defined as an mMES of 0.
Time frame: At Week 52
Proportion of participants who achieve clinical remission by total Mayo Score (MS) at Week 16
Clinical remission is defined as total MS ≤2 with no subscore \>1. The total Mayo score (MS) is a composite index designed to measure ulcerative colitis (UC) disease activity and consists of 4 subscores: RB and SF, which are patient-reported subscores, Physician's global assessment (PGA), and endoscopic findings. Individual items are rated 0 to 3, giving the composite score a maximum of 12, with higher scores indicating greater disease severity.
Time frame: At Week 16
Proportion of participants who achieve clinical remission by total Mayo Score (MS) at Week 52
Clinical remission is defined as total MS ≤2 with no subscore \>1.
Time frame: At Week 52
Proportion of participants who achieve clinical response by total MS at Week 16
Clinical response by total MS is defined as a decrease from baseline in the total MS of ≥3 points and at least 30% reduction from baseline, and a decrease in the RB subscore of ≥1 or an absolute RB subscore of 0 or 1.
Time frame: At Week 16
Proportion of participants who achieve clinical response by total MS at Week 52
Clinical response by total MS is defined as a decrease from baseline in the total MS of ≥3 points and at least 30% reduction from baseline, and a decrease in the RB subscore of ≥1 or an absolute RB subscore of 0 or 1.
Time frame: At Week 52
Proportion of participants who achieve clinical response by mMS at Week 16
Clinical response by mMS is defined as a decrease from baseline in the mMS of ≥2 points and an improvement of ≥30% from baseline plus a decrease in RB subscore ≥1 or an absolute RB subscore ≤1.
Time frame: At Week 16
Proportion of participants who achieve clinical response by mMS at Week 52
Clinical response by mMS is defined as a decrease from baseline in the mMS of ≥2 points and an improvement of ≥30% from baseline plus a decrease in RB subscore ≥1 or an absolute RB subscore ≤1.
Time frame: At Week 52
Proportion of participants who achieve clinical remission by mMS at Week 52
Clinical remission is defined as an mMS score of 0 to 2, including SF subscore of 0 or 1, RB subscore of 0, and mMES of 0 or 1 (score of 1 does not include friability).
Time frame: At Week 52
Change from baseline in PRO-2 (Patient Reported Outcome) total score (SF and RB)
PRO-2 (Patient Reported Outcome) score is defined as the sum of Mayo SF and RB subscores.
Time frame: From Baseline to Week 16 and up to End of Study (approximately 164 weeks)
Change from baseline in mMS (SF, RB, and mMES)
Each component of the mMS (SF, RB, and mMES) is scored from 0 to 3. The total mMS ranges from 0 to 9 with higher scores indicating greater disease severity.
Time frame: From Baseline to Week 16 and up to End of Study (approximately 164 weeks)
Change from baseline in Partial Mayo Score (PMS) (SF, RB, and Physician's Global Assessment [PGA])
The Partial Mayo Score (PMS) includes the SF, RB, and PGA components. It ranges from 0 to 9 with higher score indicating highest severity.

Proportion of participants who achieve histological improvement by Original Geboes Score (OGS) to assess inflammation in UC
Histological improvement is defined as OGS ≤3.1. Original Geboes Score (OGS) is a 6-grade classification system that assesses inflammation severity. Each grade includes subgrades for more specific histological features. Assessment uses the worst area of the biopsy rather than the average. Higher grades indicate greater inflammatory activity in the colon.
Time frame: At Week 16
Proportion of participants who achieve histological remission by Robarts Histopathology Index (RHI)
Histological remission is defined as RHI ≤3. The Robarts Histopathology Index (RHI) assesses 4 characteristics of mucosal activity, inflammatory infiltrate, lamina propria neutrophils, neutrophils in epithelium, and erosion or ulceration, all of which are rated on a scale of 0 to 3. Each characteristic is weighted to produce a total score ranging from 0 (no disease activity) to 33 (most severe disease activity).
Time frame: At Week 16
Proportion of participants who achieve histological remission by OGS to assess inflammation in UC
Histological remission is defined as OGS \<2B.1.
Time frame: At Week 16
Proportion of participants who achieve Histologic Endoscopic Mucosal Improvement (HEMI)
HEMI is defined by achievement of modified Mayo endoscopic improvement (mMES of 0 or 1 where 1 does not include friability) and histologic improvement (OGS ≤3.1).
Time frame: At Week 16
Change from baseline in Inflammatory Bowel Disease Questionnaire (IBDQ)
This captures the patient's experience of inflammatory bowel disease (IBD) on 4 domains of functioning and well-being: bowel and systemic symptoms and emotional and social function. The Inflammatory Bowel Disease Questionnaire (IBDQ) is a 32-item instrument assessing health-related quality of life in IBD patients across four dimensions: bowel symptoms (10 items), systemic symptoms (5 items), emotional function (12 items), and social function (5 items). Each question evaluates experiences over the previous two weeks on a 7-point Likert scale from 1 (worst) to 7 (best). The total score ranges from 32 to 224, with higher scores indicating better quality of life. Both domain-specific and overall scores can be calculated.
