Brief summary

1. Response rate measured by Bristol Stool Scale. BSS response is defined as at least 50% reduction in the number of days with at least one stool that has a consistency of 6 or 7 per week compared to baseline for a minimum of 13 of the 26 measurements (i.e. at least 50% improvement of stool consistency during treatment) and 2. Response rate measured by the 11-point numeric rating scale (NRS). Abdominal Pain Intensity response is defined as a decrease in the weekly average of worst abdominal pain

Detailed description

Response rate measured by the 7-point IBS Global Assessment of Improvement Scale (IBS-GAI) during the 26 weeks of treatment. IBS-GAI response is defined as at least 50% moderate or substantial improvement during the 26 weeks of treatment • Response rate measured by the 11-point numeric rating scale during the 26 weeks of treatment. Response is defined as ≥30% improvement in Abdominal Pain Intensity weekly response compared to baseline for a minimum of 20 of the 26 measurements (i.e. 75% improvem
