Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Phase II: NTC015 low dose (Mannitol 50 g)
One day single dose preparation same day of colonoscopy
|
Participants should self administer the preparation within 30 minutes and drink clear liquid according to local practice at the centre to prevent dehydration
|
Experimental: Phase II: NTC015 medium dose (Mannitol 100 g)
One day single dose preparation same day of colonoscopy
|
Participants should self administer the preparation within 30 minutes and drink clear liquid according to local practice at the centre to prevent dehydration
|
Experimental: Phase II: NTC015 high dose (Mannitol 150 g)
One day single dose preparation same day of colonoscopy
|
Participants should self administer the preparation within 60 minutes and drink clear liquid according to local practice at the centre to prevent dehydration
|
Experimental: Phase III: NTC015 selected dose
One day single dose preparation same day of colonoscopy
|
Participants should self administer the preparation within 30 minutes and drink clear liquid according to local practice at the centre to prevent dehydration
|
Active Comparator: Phase III: Polyethylene glycol plus ascorbate solution (2L PEG ASC) (Moviprep®)
Two litres of Moviprep® taken according to split-dose regimen (to commence in the evening before colonoscopy)
|
The instructions for product administration are followed according to the Summary of Product Characteristics. One treatment consists of two litres of Moviprep® taken according to split-dose regimen. The first litre of Moviprep® is prepared by dissolving one sachet A and one sachet B together in water to make one litre of solution. The reconstituted solution must be drunk over a period of one to two hours the evening before colonoscopy. About half a litre of clear liquid should be drunk in the next hour to prevent dehydration according to local practice at the centre. This process should be repeated with a second litre of Moviprep® prepared by dissolving one sachet A and one sachet B together in water to make one litre of solution in the early morning of the day of the procedure.

The BOCLIR is a questionnaire filled in by patients to measure the acceptability and tolerability of bowel cleansers consisting of three unidimensional scales (satisfaction, symptoms and activity limitations) with good psychometric and scaling properties. Item responses are summed to provide a score for each scale and a total score. The satisfaction scale contains eight items and the score ranges from 0 (highly satisfied) to 32 (highly dissatisfied). The symptoms scale includes 14 items and the score ranges from 0 (no symptoms) to 42 (severe symptoms). The activity limitations scale is made up of 12 items and the score ranges from 0 (no effect on activities) to 36 (activities greatly affected). The total score is the sum of the three scales and ranges from 0 to 110. Patients who report a worse experience in terms of the three factors score higher on the BOCLIR scale. |
