Description détaillée
The study evaluates the efficacy and safety of ibodutant 10 mg, given once daily for 12 weeks in comparison with placebo in female IBS-D patients. Randomisation to ibodutant and placebo will be 1:1. Efficacy is evaluated in terms of weekly response for abdominal pain intensity and stool consistency over 12 weeks of treatment in at least 50% of the weeks of treatment.
The clinical phase of the study comprises up to 2 weeks of screening for patient's eligibility, a 2-week run-in period (treatment-free) for IBS severity assessment, a 12-week double-blind treatment period, a 4-week randomised withdrawal (RW) period and a 2-week safety follow-up, resulting in a maximum 22-week overall duration of the study for each patient.
Patients report their IBS-related symptoms daily in a telephone-based electronic diary from run-in until end of treatment.

Délai: 4 weeks
|
Comparison between average abdominal pain intensity (worst abdominal pain on a 0 to 10 NRS scale, where 0 corresponds to no pain and 10 corresponds to worst possible pain) and average stool consistency score (the patients reported Bristol Stool Chart score based on a 1 to 7 NRS scale where 1 corresponds to hard stool and 7 corresponds to watery diarrhoea) during the 4-week RW presented as change to baseline. The analysis only included the patients randomised to ibodutant in the 12-week treatment period and re-randomised to placebo for the 4-week RW period. Baseline was considered as the average abdominal pain intensity/stool consistency in the 2-week Run-in period. |
