Evaluation of the Efficacy, Safety and Tolerance of Experimental Morning-only MOVIPREP® Bowel Preparation in Comparison With Split-dose With Nocturnal Pause MOVIPREP® Bowel Preparation

Multicenter Endoscopist-blinded Randomized Parallel-group Comparative Study to Assess Efficacy, Safety and Tolerance of Morning-only Dosing Compared to Control Split-dosing With Nocturnal Pause in MOVIPREP® Bowel Preparation Prior to Colonoscopy

To compare colon cleansing quality induced by the 2 different modes of MOVIPREP® intake in 5 colon segments prior to colonoscopy.

All participants enrolled to the study will be allocated to one of two arms. Patients of the experimental morning-only regimen arm will prepare and take MOVIPREP® solution in the full dose - 2 litres of MOVIPREP® preparation in the early morning on the day of the colonoscopy clinical procedure. Participants in the standard split-dose regimen arm will prepare and take MOVIPREP® solution in split doses - ½ of dose (1 litre) the evening before + ½ of dose (1 litre) of MOVIPREP® preparation in the morning of the day of the colonoscopy.

The study consists of three visits. Participation in the study lasts no more than 11 days; 3 days as minimum.

There is no follow-up period planned except in case of any adverse events (AEs) when the follow-up period will last until the participant has recovered or until all AE-related queries for the participant have been resolved.
