Colonoscopy Clinical Trial
Official title:
A Prospective Randomised Single-Blinded Multicentric and Pivotal Phase III Study Comparing the Efficacy, Safety and Acceptability of a New 2 Litres Gut Lavage Solution NRL994 Versus a Sodium Phosphate Solution for Colonoscopy Preparation
The aim of the study is to compare a new 2 litre bowel cleansing product versus a sodium phosphate solution already on the market. Efficacy of each bowel preparation, safety and acceptability will be assessed.
Multicentric (15 centres), prospective, randomised, single-blinded phase III pivotal study
in patients undergoing a colonoscopy. Gut cleansing will be performed using 2 litres of
NRL994 gut lavage solution with 1 litre (or more) of extra clear liquids or 2 x 45 ml of a
sodium phosphate solution plus 2 litres (or more) of extra clear liquids the day before
colonoscopy. Patients requiring a morning colonoscopy who fulfil the inclusion criteria,
will be randomised. One of the two tested products will be delivered by a pharmacist,
blindly from the gastroenterologist. The assigned product will be taken the day before the
coloscopy according to the information leaflet. Efficacy of the two tested preparations will
be measured on video-tape record of each colonoscopy by a final grading i.e. "the overall
quality of colonoscopy prep" by an gastroenterologist expert. A standardised patient
questionnaire administered by a nurse on the morning before colonoscopy will assess clinical
tolerance and acceptability (satisfaction) of the prep. A baseline blood sampling will be
withdrew before intake of the preparation and one more blood sample will be performed after
the intake on the morning, before the coloscopy.
After the coloscopy, as the gastroenterologist gives the result of the coloscopy , a last
visit is performed.
