5. Patient has any of the following surgical history:
a. Cholecystectomy with ANY history of post cholecystectomy biliary tract pain. Patients who had a successful cholecystectomy with no post operative biliary tract pain are candidates for the study;
b. Any abdominal surgery within the 3 months prior to Prescreening;
c. Patient has a history of major gastric, hepatic, pancreatic, or intestinal surgery (appendectomy, hemorrhoidectomy, or polypectomy greater than 3 months post surgery are allowed).
(Refer to protocol for criteria 6. to 35.) |

E.5 End points |
E.5.1 | Primary end point(s) |
While the designation of the relevant endpoints as primary and secondary within this protocol are based upon a potential NDA, the study is designed to also support potential marketing applications in other global regions. As such, endpoints designated as primary for the US FDA may be considered secondary by other regulatory agencies while endpoints designated as secondary for the US FDA may be considered primary by other regulatory agencies. To support a potential Marketing Authorization Application (MAA) to the European Medicines Agency (EMA), pain responder status (designated as a secondary endpoint for the US FDA as described in Section E.5.2) and IBS global symptom responder status (designated as a secondary endpoint for the US FDA as described in Section E.5.2) will be considered co-primary efficacy endpoints.
The primary efficacy endpoint is the composite responder status determined over the initial 12-week treatment period. A patient will be defined as a study composite responder if he or she meets the daily composite response criteria for at least 50% of days with diary entry during the interval from Weeks 1-12. A patient must meet BOTH of the following criteria on a given day for a daily response:
• Pain response: worst abdominal pain score in the past 24 hours improved by ≥30% compared to the average in the week prior to randomization
• Stool consistency response: BSS score <5 or the absence of a bowel movement if accompanied by ≥30% improvement in worst abdominal pain
To be eligible to be a responder, a patient must have a minimum of 60 days of diary entries over the interval from Weeks 1-12. Any patient with fewer than 60 days of diary entry will be considered a non-responder.
For further details please refer to the protocol.
Analysis of the primary endpoints will be elucidated in the statistical analysis plan.
A separate statistical analysis plan will be developed to support a potential MAA to the EMA based on the alternatively designated co-primary efficacy endpoints. |

E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
• Pain responders over the interval Weeks 1-4; Weeks 5-8; Weeks 9-12; Weeks 1-12; and Weeks 1-26: defined as those patients who meet the daily pain response criterion for at least 50% of days with diary entry during the interval. The daily pain response criterion is defined as worst abdominal pain score in the past 24 hours improved by ≥30% compared to the average in the week prior to randomization. To be eligible to be a responder, a patient must have a minimum of 20 days of diary entries over any 4-week interval, a minimum of 60 days of diary entries over the 12-week interval, and a minimum of 110 days over the 26-week interval.
• Stool consistency responders over the intervals from Weeks 1-4; Weeks 5-8; Weeks 9-12; Weeks 1-12 and Weeks 1-26: defined as those patients who meet the daily stool consistency response criterion for at least 50% of days with diary entry during the interval. The daily stool consistency response criterion is defined as BSS score <5 or the absence of a bowel movement if accompanied by ≥30% improvement in worst abdominal pain. To be eligible to be a responder, a patient must have a minimum of 20 days of diary entries over any 4-week interval, a minimum of 60 days of diary entries over the 12-week interval, and a minimum of 110 days over the 26-week interval.
• IBS global symptom responders over the interval from Weeks 1-4; Weeks 5-8; Week 9-12; Weeks 1-12; and Weeks 1-26: defined as those patients who meet the daily IBS global symptom response criterion for at least 50% of days with diary entry during the interval. The daily IBS global symptom responder criterion is defined as an IBS global symptom score of 0 (none) or 1 (mild) or a daily IBS global symptom score improved by ≥2.0 compared to the average in the week prior to randomization. To be eligible to be a responder, a patient must have a minimum of 20 days of diary entries over any 4-week interval, a minimum of 60 days of diary entries over the 12-week interval, and a minimum of 110 days over the 26-week interval
• IBS-QoL responders: defined as patients who have achieved at least a 14 point improvement in IBS-QoL score. This definition applies to each timepoint of administration for the IBS-QoL total and subscale scores
• IBS adequate relief responders over the interval from Weeks 1-12 and Weeks 1-26: defined as those patients with a weekly response of “Yes” to adequate relief of their IBS symptoms for at least 50% of the total weeks during the interval.
Further secondary endpoints include:
• Discomfort: changes from baseline in daily abdominal discomfort scores
• Bloating: changes from baseline in daily abdominal bloating scores
• Frequency: changes from baseline in number of bowel movements per day
• Incontinence: changes from baseline in number of bowel incontinence episodes per day and number of incontinence-free days
• Urgency: number of urgency episodes per day
• IBS-QoL: total score and subscale scores compared to baseline |
