Investigation of PICOPREP and PEG-ELS for Bowel Preparation for Colonoscopy
December 17, 2012 updated by: Ferring Pharmaceuticals
A Multi-center, Randomized, Single-blind Clinical Study of the Efficacy and Safety of PICOPREP and Polyethylene Glycol-electrolyte 4000 Powder for Oral Solution (PEG-ELS) for the Bowel Preparation Prior Colonoscopy
Eligible subjects undergoing a colonoscopy will randomly receive either PICOPREP or polyethylene glycol 4000 electrolyte lavage solution before the procedure to evaluate its effectiveness, tolerability and safety.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: PICOPREP
"Split Dose" method and consists of two separate doses: the first dose during the evening before the colonoscopy and the second dose the next day before the colonoscopy.
|
|
Active Comparator: PEG-ELS
PEG-ELS was used according to the approved labeled dosage and administration instructions.
Only received one dose of 2 boxes (6 packets), administrated on the day of colonoscopy examination.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The Ottawa Scale Score of Patients Who Had Successfully Completed the Colonoscopy Examination After Having Completed the Study Bowel Preparation
Time Frame: day 2
|
The total Ottawa Bowel Preparation Scale (OBPS) score, rated by the treatment-blinded Investigator at colonoscopy, was designed to evaluate cleanliness of the colon by grading the endoscopic visibility of the mucosa according to a scale from 0 ('excellent' visibility) to 4 ('inadequate' visibility); The component scores for each of the colon segment are added together, along with an overall 'fluid' score (from small amount = 0, to large amount = 2).
Thus, the total OBPS has a range from 0 (a perfect preparation) to 14 (a completely unprepared bowel)
|
day 2

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Patient Response to Acceptability and Tolerability Questionnaire
Time Frame: Day 2
|
On the day of the procedure, but before colonoscopy or any sedation for colonoscopy, subjects were asked to complete a standardised questionnaire regarding whether or not complete the IMP (yes or no), ease of taking IMP (rating from 1 point(very easy) to 5 point (very difficult)), degree of acceptability to study med (rating from 1 point (excellent) to 5 point (bad)), palatability of IMP (rating from 1 point (excellent) to 5 point (bad)) and tolerability (5 adverse reactions including abdominal bloating, spasms, nausea, vomiting and general malaise which were generally reported in bowel preparation with rating according to intensity from 1 point (None) to 4 point (Severe)).
|
Day 2
|
Ottawa Scale Score by Colon Segment
Time Frame: Day 2
|
Mean Ottawa Scale scores, and score categories (from 'excellent' to 'bad'), are summarised by colon segment together with the overall fluid content score
|
Day 2
|
Percentage of Successful Completion of Colonoscopy
Time Frame: Day 2
|
An overview of completion rates of colonoscopy (i.e., endoscope reaching the ileocecal valve)
|
Day 2
|
Proportion of Successful Colonoscopies in the Clinical Setting (Predicted by Ottawa Scale Score)
Time Frame: Day 2
|
At colonoscopy, bowel preparations were rated by the treatment-blinded endoscopist, as being of an overall quality "adequate for clinical diagnostic purposes" (Y/N).
The total Ottawa Scale scores was correlated with 'adequate' or 'inadequate' quality of bowel preparation for clinical diagnostic purposes
|
Day 2
|
Proportion of Subjects Requiring a Repeat Colonoscopy Due to Poor Bowel Preparation
Time Frame: Day 2
|
The Proportion of subjects requiring a repeat colonoscopy due to poor bowel preparation
