Brief summary
Irritable Bowel Syndrome with diarrhoea (IBS-D) is a functional gastrointestinal disorder characterised by chronic or recurrent abdominal pain or discomfort and diarrhoea. This trial aims at the evaluation of the efficacy and safety of the neurokinin type 2 receptor antagonist Ibodutant in improving IBS-D symptoms.
Detailed description
The study evaluates the efficacy and safety of three doses of ibodutant, given once daily for 8 weeks versus placebo in IBS-D patients. Efficacy is evaluated in terms of overall symptom relief and abdominal pain/discomfort relief after 8 weeks of treatment. The clinical phase of the study comprises a 2-week run-in period (treatment-free),an 8-week double-blind treatment period and a 2-week treatment withdrawal period, resulting in a 10-week overall duration of the study for each patient. Patients report their IBS-related symptoms daily in an electronic diary (web-and telephone based)during all periods of the study.
Interventions
Oral tablet, low dose, once daily, for 8 weeks
Oral tablet, (identical in appearance and weight to Ibodutant tablets), once daily, for 8 weeks

Participant flow
Recruitment details
First subject screened 06/10/2010, first subject randomised 22/10/2010, last subject out 11/05/2012, at 78 study sites in 8 European countries (Bulgaria, Czech Republic, Denmark, Germany, Italy, Poland, Spain, and Sweden)
Pre-assignment details
A run-in period was planned to confirm eligibility criteria. 5 more patients were randomized instead of the planned number (560) because due to the high screen fail rate it was impossible to predict with how many patients the enrollment goal would be reached. Although the enrollment goal was reached these 5 patients in screening continued the study
