What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Abdominal Pain at Its Worst on a NRS Through the Treatment Period	Abdominal pain is measured daily in an eDiary, using an 11-point NRS, where 0 is anchored with "no abdominal pain" and 10 is anchored with "worst possible abdominal pain." The postbaseline weekly abdominal pain score is the average of the non-missing daily abdominal pain at its worst scores during a week (Weeks 1-12) if there are at least 4 daily scores entered into the eDiary during the week. Weekly change from baseline was calculated for each week as the weekly score minus the baseline score. Mixed model repeated measures (MMRM) results are based on a repeated measures analysis with treatment, analysis week, and treatment-by-week interaction as fixed effects and baseline as covariate. An unstructured covariance structure was used to model intra-subject correlation with subjects as a random effect. Baseline is derived from the eDiary data collected daily in the Pretreatment Period, specifically the period of time from 14 days before randomization up to the time of randomization.	Baseline, up to Week 12 (end of the Treatment Period)
Percentage of Participants Who Were 6/12 Week Abdominal Pain 30% Change Responders	A 6/12 Week Abdominal Pain 30% Responder was a participant who had a decrease from baseline of ≥30% in the weekly abdominal pain score for that week for at least 6 out of the 12 weeks of the Treatment Period; for any week, a participant with < 4 daily abdominal pain scores available was considered a non-responder for that week. Abdominal pain is measured daily in an eDiary, using an 11-point NRS, where 0 is anchored with "no abdominal pain" and 10 is anchored with "worst possible abdominal pain." The postbaseline weekly abdominal pain score is the average of the non-missing daily abdominal pain at its worst scores during a week (Weeks 1-12) if there are at least 4 daily scores entered into the eDiary during the week.	Baseline through Week 12
