12-Week Efficacy and Safety Study of Ibodutant in Women With Irritable Bowel Syndrome With Diarrhea (IBS-D) (IRIS-3)
A 12-Week Double-blind, Randomised, Placebo-controlled, Parallel Group Phase III Study, Followed by a 4-Week Randomised Withdrawal Period to Evaluate the Efficacy and Safety of Oral Ibodutant 10 mg Once Daily in Female Patients With Irritable Bowel Syndrome With Diarrhea
研究概览
详细说明
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.

大体时间: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. |
