12-Week Efficacy and Safety Study of Ibodutant in Women With Irritable Bowel Syndrome With Diarrhea (IBS-D) (IRIS-3)

18 de novembro de 2016 atualizado por: Menarini Group

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

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 oral ibodutant 10 mg once daily as compared to placebo in women with IBS-D over a 12-week treatment period.

Visão geral do estudo

Descrição detalhada

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.

Medida de resultado
Descrição da medida
Prazo
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).
Prazo: 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.

12 weeks
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).
Prazo: 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".
12 weeks
Evaluation of Rebound Effects
Prazo: 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.
