Outcome Measures
Primary Outcomes (1)
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; * 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. The patients reported Bristol Stoll Chart score based on a 1 to 7 scale where 1 corresponds to hard stool and 7 corresponds to watery diarrhoea.

Evaluation of Rebound Effects
4 weeks
Study Arms (2)
Ibodutant 10 mg
EXPERIMENTALOral tablet to be given once daily for 12 weeks of treatment. Patients randomised to the ibodutant 10 mg arm will be re-randomised at week 13 in a 1:1 ratio to either ibodutant 10 mg or placebo for additional 4 weeks of treatment.
Placebo
PLACEBO COMPARATOROral tablet to be given once daily for 12 weeks of treatment. Patients randomised to the placebo arm will be mock-re-randomised (switch in blinded conditions) to ibodutant at week 13 for additional 4 weeks of treatment.
Interventions
Oral tablet, to be given once daily.
Oral tablet, (identical in appearance and weight to ibodutant tablets), to be given once daily.
