Tiltaksbeskrivelse
Tidsramme
Percentage of Participants with Clinical Remission
Tidsramme: At Week 12

Percentage of participants achieving Modified Mayo Score (mMS) <=2 with stool frequency subscore (SFS) = 0 or 1 (up to 1-2 stools more than normal), rectal bleeding subscore (RBS) = 0 (no blood seen) and endoscopic subscore (ES) = 0 or 1 (normal appearance of mucosa or mild disease) at Week 12. mMS is a composite score of ulcerative colitis disease activity, given by the sum of three subscores: SFS, RBS and ES. Each subscore is measured on a scale from 0 to 3, with higher values associated with greater severity.

Change in pmMS from baseline to Week 2. pmMS is a composite score of ulcerative colitis signs and symptoms activity given by the sum of the SFS and RBS. SFS is measured on a scale from 0 (normal number of stools) to 3 (5 or more stools than normal). RBS is measured on a scale from 0 (no blood seen) to 3 (blood alone passed).

From baseline to Week 2
Percentage of Participants with Endoscopic Improvement
Tidsramme: At Week 12

Percentage of participants achieving endoscopic subscore of 0 or 1 (normal appearance of mucosa or mild disease) at Week 12.

At Week 12
Percentage of Participants with Endoscopic Remission
Tidsramme: At Week 12

Percentage of participants achieving endoscopic subscore of 0 (normal appearance of mucosa) at Week 12.

At Week 12
Percentage of Participants with Clinical Response
Tidsramme: At Week 12

Percentage of participants achieving a decrease in mMS of at least 2 points and 30% from baseline and either a decrease in RBS >= 1 or RBS = 0 or 1 (no blood seen or stool with streaks of blood) at Week 12. mMS is a composite score of ulcerative colitis disease activity, given by the sum of three subscores: SFS, RBS and ES. SFS is measured on a scale from 0 (normal number of stools) to 3 (5 or more stools than normal). RBS is measured on a scale from 0 (no blood seen) to 3 (blood alone passed). ES is measured on a scale from 0 (normal appearance of mucosa) to 3 (severe disease).

At Week 12
Percentage of Participants with Histologic Improvement
Tidsramme: At Week 12

Percentage of participants achieving a histologic improvement, defined as Geboes <=3.1 at Week 12. Geboes is a grading system for histologic ulcerative colitis disease activity with scores ranging from 0 (no activity) to 5.4 (ulcer or granulation tissue).

At Week 12
Percentage of Participants with Histologic Remission
Tidsramme: At Week 12

Percentage of participants achieving a histologic remission, defined as Geboes <2B at Week 12. Geboes is a grading system for histologic ulcerative colitis disease activity with scores ranging from 0 (no activity) to 5.4 (ulcer or granulation tissue).

At Week 12
Participants with Histologic-Endoscopic Mucosal Improvement
Tidsramme: At Week 12

Percentage of participants achieving Geboes <= 3.1 and ES = 0 or 1 (normal appearance of mucosa or mild disease) at Week 12. Geboes is a grading system for histologic ulcerative colitis disease activity with scores ranging from 0 (no activity) to 5.4 (ulcer or granulation tissue).

At Week 12
Percentage of Participants with Histologic-Endoscopic Remission
Tidsramme: At Week 12

Percentage of participants achieving Geboes < 2 and ES = 0 or 1 (normal appearance of mucosa or mild disease) at Week 12. Geboes is a grading system for histologic ulcerative colitis disease activity with scores ranging from 0 (no activity) to 5.4 (ulcer or granulation tissue).

At Week 12
Percentage of Participants with Clinical Remission: Among Biomarker-Defined Subgroups of Participants
Tidsramme: At Week 12

Percentage of participants achieving mMS <= 2 with SFS = 0 or 1 (up to 1-2 stools more than normal), RBS = 0 (no blood seen) and ES = 0 or 1 (normal appearance of mucosa or mild disease) at Week 12 in biomarker-defined subgroups. mMS is a composite score of ulcerative colitis disease activity, given by the sum of three subscores: SFS, RBS and ES. Each subscore is measured on a scale from 0 to 3, with higher values associated with greater severity.

At Week 12
Percentage of Participants with Endoscopic Improvement: Among Biomarker-Defined Subgroups of Participants
Tidsramme: At Week 12

Percentage of participants achieving endoscopic subscore of 0 or 1 (normal appearance of mucosa or mild disease) at Week 12 in biomarker-defined subgroups.

At Week 12
Change in Bowel Urgency
Tidsramme: Baseline through Week 12

Change in bowel urgency from baseline through Week 12. Bowel urgency is measured on a scale from 0 (None) to 4 (Severe).

Baseline through Week 12
Change in Abdominal Pain
Tidsramme: Baseline through Week 12

Change in abdominal pain from baseline through Week 12. Abdominal pain is measured on a scale from 0 (None) to 4 (Severe).

Baseline through Week 12
Change in Fatigue
Tidsramme: Baseline to Week 12

Change in fatigue as measured by the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) from baseline to Week 12. FACIT-Fatigue is a 13-item self-reported assessment of the level and impact of fatigue. The overall FACIT-Fatigue score ranges between 0 and 52, with higher scores associated with better quality of life concerns related to fatigue.

Baseline to Week 12
Change in Health-Related Quality of Life
Tidsramme: Baseline to Week 12

Change in Inflammatory Bowel Disease Questionnaire (IBDQ) score from baseline to Week 12. IBDQ is a 32-item self-reported assessment of health-related quality of life in participants with inflammatory bowel disease. The overall IBDQ score ranges from 32 to 224, with higher scores associated with better health-related quality of life.

Baseline to Week 12
Overall Change in UC Symptoms
Tidsramme: Baseline to Week 2 and Week 12

Patient Global Impression of Change (PGIC) from baseline to Weeks 2 and 12. PGIC measures overall change in ulcerative colitis symptoms from "Much better" to"Much worse".

Baseline to Week 2 and Week 12
Overall Severity in UC Symptoms
Tidsramme: Baseline to Week 2 and Week 12

Patient Global Impression of Severity (PGIS) from baseline to Weeks 2 and 12. PGIS measures severity of ulcerative colitis symptoms from "None" to "Very severe".

Baseline to Week 2 and Week 12
Incidence and Severity of Adverse Events (AEs)
Tidsramme: Up to 30 Weeks after Baseline

Incidence and severity of AEs, including serious AEs, AEs leading to treatment discontinuation and AEs of special interest.

Up to 30 Weeks after Baseline
