Primary Endpoints
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.

Secondary Endpoints
Change from Baseline in weekly abdominal score over Weeks 7 to 12
Baseline, Weeks 7 to 12 (time - average)
