Change from Baseline in Weekly Abdominal pain intensity (API) over Weeks 7 to 12
Baseline, Weeks 7 to 12 (time - average)

Participants rate their pain intensity daily on a numeric rating scale from 0 (no pain) to 10 (worst possible pain). Weekly API scores are derived by averaging daily API scores. Higher score indicates worst outcome. A repeated measures statistical analysis is applied to weekly scores, and the result for the Weeks 7 to 12 interval is obtained by averaging adjusted mean estimates for Weeks 7, 8, 9, 10, 11 and 12.

Change from baseline in weekly mean Worst Itch Numeric Rating Scale (WI-NRS) score
Week 4

Assessed by Worst Itch Numeric Rating Scale \[WI-NRS\] The WI-NRS is a single item questionnaire assessing the patient-reported severity of itch at its most intense during the previous 24-hour period on a scale of 0 to 10, with 0 being 'no itch' and 10 being 'the worst itch imaginable'. Higher scores indicate worse severity.
