Change From Baseline in Bowel Urgency
Periodo de tiempo: 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
