- Registration Number
- NCT01827592
- Lead Sponsor
- Ferring Pharmaceuticals
- Brief Summary
Efficacy and Safety Trial of elobixibat in Patients with Chronic Idiopathic Constipation treated for 26 Weeks.
- Detailed Description
The present trial was designed to determine the efficacy and safety of elobixibat treatment (at both doses of 5 mg and 10 mg/day) compared to placebo treatment for 26-week Treatment Period in patients with chronic idiopathic constipation. Patients were followed-up for 2 weeks after end of the Treatment Period.

- Primary Outcome Measures
Name Time Method Overall Complete Spontaneous Bowel Movement (CSBM) Response During the first 12 weeks This outcome measured the percentage of patients who were CSBM responders. A CSBM responder was defined as a patient with ≥3 CSBMs per week and an increase of ≥1 CSBM per week from Baseline, for at least 9 of the 12 weeks in the 12-week Treatment Period, including at least 3 weeks during Weeks 9-12.
- Secondary Outcome Measures
Name Time Method Occurrence of CSBM Response Within the first 24 hours of treatment initiation This outcome measured the percentage of patients who had a CSBM within 24 hours after the first dose of treatment. A CSBM was defined as a spontaneous (occurring without laxative within the preceding 24 hours, including no rescue medication within the preceding 24 hours) bowel movement (as interpreted by the patient, with a beginning and an end, including single or multiple stools), accompanied by a patient reported sense of complete evacuation ('complete').
Change From Baseline in Weekly Frequency of Spontaneous Bowel Movements (SBMs) From Baseline (2-week Pretreatment Period) to overall first 12-weeks of Treatment Period The change from Baseline for the continuous variable was estimated using a repeated measures analysis of covariance (ANCOVA) model.
Change From Baseline in Weekly Stool Consistency of SBMs From Baseline (2-week Pretreatment Period) to overall first 12-weeks of Treatment Period The stool consistency is measured using the seven-point ordinal Bristol Stool Form Scale (BSFS) score. The BSFS classifies human stool into seven types and points them accordingly.
Type 1: Separate hard lumps, like nuts (hard to pass) Type 2: Sausage-shaped, but lumpy Type 3: Like a sausage but with cracks on its surface Type 4: Like a sausage or snake, smooth and soft Type 5: Soft blobs with clear cut edges (passed easily) Type 6: Fluffy pieces with ragged edges, a mushy stool Type 7: Watery, no solid pieces, entirely liquid Types 1 and 2 indicate constipation, with 3 and 4 represents the ideal stool form (especially the latter), and 5, 6 and 7 tends towards diarrhoea .
For a given assessment week, the weekly stool consistency was defined as the sum of non-missing stool consistency score for SBMs during that week divided by the number of non-missing stool consistency score for SBMs during that week. The parameter was analysed using repeated measures ANCOVA model.Total Patient Assessment of Constipation - Quality of Life (PAC-QOL) Score Responder At 12 weeks This outcome measured the percentage of patients who were PAC-QOL score responder at 12-week of Treatment Period. A PAC-QOL score responder was defined as a patient with ≥50% reduction in total PAC-QOL score from Baseline at Week 12.
PAC-QOL is a 28-item questionnaire for psychometric assessment of disease-specific quality of life. The questionnaire is based on 5-point Likert scale; ranging from 0 \[none of the time or not at all\] to 4 \[all of the time or extremely\]). A lower score indicates a better Quality of Life. The PAC-QOL questionnaire is developed specifically for patients with constipation.
Total PAC-QOL score was averaged from the individual item score.Change From Baseline in Weekly Degree of Straining of SBMs From Baseline (2-week Pretreatment Period) to overall first 12-weeks of Treatment Period The degree of straining was measured using the five-point ordinal scale (1=Not at all, 2=A little bit, 3=A moderate amount, 4=A great deal, and 5=An extreme amount).
For a given assessment week, the weekly degree of straining was defined as the sum of non-missing straining score for SBMs during that week divided by the number of non-missing straining score for SBMs during that week. The parameter was analysed using repeated measures ANCOVA model.Change From Baseline in Weekly Abdominal Bloating Score From Baseline (2-week Pretreatment Period) to overall first 12-weeks of Treatment Period The abdominal bloating score was measured using the five-point ordinal scale (1=None, 2=Mild, 3=Moderate, 4=Severe, and 5=Very severe).
For a given assessment week, the weekly abdominal bloating score was defined as the sum of non-missing abdominal bloating score for SBMs during that week divided by the number of non-missing abdominal bloating score for SBMs during that week. The parameter was analysed using repeated measures ANCOVA model.Change From Baseline in Weekly Abdominal Discomfort Score From Baseline (2-week Pretreatment Period) to overall first 12-weeks of Treatment Period The abdominal discomfort score was measured using the five-point ordinal scale (1=None, 2=Mild, 3=Moderate, 4=Severe, and 5=Very severe).
For a given assessment week, the weekly abdominal discomfort score was defined as the sum of non-missing abdominal discomfort score for SBMs during that week divided by the number of non-missing abdominal discomfort score for SBMs during that week. The parameter was analysed using repeated measures ANCOVA model.
