About this study

Official title: A 52-Week, Double-blind, Randomised, Placebo-controlled, Parallel-group Phase III Study With Re-randomisations at Week 25 to Evaluate the Efficacy and Safety of Oral Ibodutant 10 mg Once Daily in Female Patients With Irritable Bowel Syndrome With Diarrhoea (IBS-D)

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 24-week treatment period.

Read the detailed description

The study evaluates the efficacy and safety of ibodutant 10 mg, given once daily for 24 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 24 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 first 24-week double-blind treatment period, a second 28-week re-randomised double-blind treatment period and a 2-week safety follow-up, resulting in a maximum 58-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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Weekly Response for Abdominal Pain Intensity AND Stool Consistency Over the First 24 Weeks of Treatment in at Least 50% of the Weeks of Treatment (12 Out of 24 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 (patients reported their worst abdominal pain on a 0 to 10 NRS scale, where 0 corresponds to no pain and 10 corresponds to worst possible pain);
    • 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 (patients reported their stool consistency response using the Bristol Stool Chart score based on a 1 to 7 NRS scale where 1 corresponds to hard stool and 7 corresponds to watery diarrhoea).

    Measured: 24 weeks

Secondary outcomes (4)

  1. Weekly Response for Abdominal Pain Intensity Over the First 24 Weeks of Treatment in at Least 50% of the Weeks of Treatment (12 Out of 24 Weeks).

    The patient will be considered a weekly abdominal pain responder if she meets the following criterion:

    • Decrease in weekly average of worst abdominal pain score in the past 24 hours of at least 30% compared with baseline.

    Measured: 24 weeks

  2. Weekly Response for Stool Consistency Over the First 24 Weeks of Treatment in at Least 50% of the Weeks of Treatment (12 Out of 24 Weeks).

    The patient was considered a weekly stool consistency responder if she met the following criterion:

    • 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.

    Measured: 24 weeks

  3. Weekly Response for Relief of Overall IBS Signs and Symptoms Over the First 24 Weeks of Treatment in at Least 50% of the Weeks (12 Out of 24)

    The patient was considered a weekly responder if she has an IBS degree-of-relief equal to "completely relieved/improved" or "considerably relieved/improved".

    Weekly e-diary assessment of IBS degree-of-relief of overall on signs or symptoms over the last 7 days was collected using a balanced 7-point Likert scale with 1= Completely relieved/improved, 2= Considerably relieved/improved, 3=Somewhat relieved/improved, 4= Unchanged, 5= Somewhat worse, 6=Considerably worse, 7= As bad as I can imagine.

    Measured: 24 weeks

  4. Sustained Analysis of Response for Abdominal Pain AND Stool Consistency Over First 24-week Double-blind Treatment Period

    Weekly response for abdominal pain intensity AND stool consistency over the first 24 weeks of treatment in at least 50% of the weeks of treatment (12 out of 24 weeks) with at least 2 weeks of response in the last 4 weeks of treatment (week 21 to 24). The patient will be considered a weekly responder as defined for the primary endpoint.

    Measured: 24 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ibodutant 10 mg in people with Irritable Bowel Syndrome With Diarrhea, run by Menarini Group at 139 sites in 9 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 23 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 3 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 139 sites in United States, Poland, United Kingdom, Germany, Hungary and 4 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Jan 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Weekly Response for Abdominal Pain Intensity AND Stool Consistency Over the First 24 Weeks of Treatment in at Least 50% of the Weeks of Treatment (12 Out of 24 Weeks). (time frame: 24 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02120027.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Mar 2017; AzTrials last refreshed its copy on 8 Nov 2026.
