Change From Baseline in Bowel Urgency
Tidsramme: From Baseline through Week 12 and Week 24
|
Bowel urgency will be assessed using two self-reported items over the past 24 hours: presence of bowel urgency (Yes/No) and severity on an 11-point numerical rating scale from 0 (no urgency) to 10 (worst possible urgency) |
From Baseline through Week 12 and Week 24

|
Change From Baseline in Abdominal Pain
Tidsramme: From Baseline through Week 12 and Week 24
|
Abdominal pain will be assessed using two self-reported items over the past 24 hours: presence of abdominal pain (Yes/No) and severity on an 11-point numerical rating scale from 0 (no pain) to 10 (worst possible pain) |
From Baseline through Week 12 and Week 24
|
|
Change From Baseline in Fatigue
Tidsramme: From Baseline through Week 12 and Week 24
|
Change in fatigue will be assessed by Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue scale. 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 |
From Baseline through Week 12 and Week 24

|
Change From Baseline in Health-Related Quality of Life
Tidsramme: From Baseline through Week 12 and Week 24
|

|
|
Change From Baseline in Overall Severity in UC Symptoms
Tidsramme: Baseline, Week 2, Week 12 and Week 24
