E.5 End points

E.5.1

Primary end point(s)

Primary Efficacy Endpoint:
Weekly response for abdominal pain intensity AND stool consistency over 12 weeks of treatment in at least 50% of the weeks of treatment (6 out of 12 weeks). The patient will be considered a weekly responder if she meets BOTH of the following criteria in the same week:
Abdominal pain response: decrease in weekly average of worst abdominal pain score in the past 24 hours of at least 30% compared with baseline (2-week Run-in period);
NOTE: “Worst abdominal pain score in the past 24 hours” hereafter will be called “abdominal pain intensity”.
Stool consistency response: decrease of at least 50% in the number of days per week with at least one stool that has a consistency of Type 6 or 7 compared with baseline (2-week Run-in period).

E.5.1.1

Timepoint(s) of evaluation of this end point

Weekly response over 12 weeks of treatment.

E.5.2

Secondary end point(s)

• Weekly response for abdominal pain intensity over 12 weeks of treatment in at least 50% of the weeks of treatment (6 out of 12 weeks). The patient will be considered a weekly responder as defined in the primary endpoint in terms of abdominal pain intensity.
• Weekly response for stool consistency over 12 weeks of treatment in at least 50% of the weeks of treatment (6 out of 12 weeks). The patient will be considered a weekly responder as defined in the primary endpoint in terms of stool consistency.
• Weekly abdominal pain responder, defined as a patient with a decrease versus baseline (2-week Run-in period) of at least 30 % in the weekly average of abdominal pain intensity from Randomisation until the end of week 12. Additionally the same endpoint will be considered with the thresholds of 40% and 50%.
• Weekly stool consistency responder defined as a patient with a decrease versus baseline (2-week Run-in period) of at least 50% in the number of days per week with at least one stool that has a consistency of Type 6 or 7 from Randomisation until the end of week 12.
• Weekly Response for relief of overall IBS signs and symptoms over 12 weeks of treatment in at least 50% of the weeks of treatment (6 out of 12 weeks). The patient will be considered a weekly responder if she has an IBS degree-of-relief equal to “Completely relieved/improved” or “Considerably relieved/improved”.
• Evaluation of rebound effect by comparison between average abdominal pain intensity and stool consistency during the 4-week RW treatment period and baseline (2-week Run-in period) in patients who are re-randomised to placebo after being treated with ibodutant.
• Change in IBS-SSS from baseline (Visit 3) after 12-week double-blind treatment period and 4-week RW treatment period.
• Change of weekly average for each week during the 12-week double-blind treatment period and the 4-week RW treatment period versus baseline (2-week Run-in period) of specific symptoms of IBS-D i.e.:
-Abdominal pain intensity.
-Abdominal discomfort intensity.
-Abdominal bloating intensity.
-Stool urgency intensity.
-Stool incontinence episodes.
-Stool frequency.
-Abdominal pain-free days.
-Stool consistency score.
