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

Study Overview
=================
Brief Summary
-----------------
To compare colon cleansing quality induced by the 2 different modes of MOVIPREP® intake in 5 colon segments prior to colonoscopy.

Detailed Description
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Successful Colon Cleansing | Bowel cleansing was assessed by a blinded endoscopist through visual evaluation of 5 colon segments and scored using the Harefield Cleansing Scale (HCS): A = success, all segments clean/scored 4 or 3; B = success, ≥1 segment with liquid/semi-solid amounts of stool, fully removable, ≥1 segment scored 2; C = failure, ≥1 segment with semi-solid or solid amounts of stool, at least 1 segment scored 1; and D = failure, ≥ 1 segment with irremovable, heavy, hard stools, ≥ 1 segment scored 0. Segmental evaluation of colon cleansing scores is as follows: 4: Colon empty and clean, no remaining stool or liquid. 3: Presence of clear liquid in the gut which can be removed by suction. 2: Brown liquid or semisolid remaining amounts of stool, fully removable. 1: Semisolid amounts of stool, only partially removable, difficult to make colonoscopy; 0: Irremovable, heavy, hard stools, colonoscopy impossible. Success of cleansing was defined as Grades of bowel cleansing А and В. | 1 day (the day of colonoscopy) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Patient Satisfaction of Colonoscopy Preparation (VAS) | Patient satisfaction was measured on a 100 mm visual analog scale (VAS) where 0 (left end of the line) is marked as totally unacceptable (lowest patient satisfaction of colonoscopy preparation) and 100 is fully acceptable (highest patient satisfaction with the procedure). Satisfaction was scored based on a mark placed on the line by the participant. | 1 day (the day of colonoscopy) | 
| Total Compliance Score | Compliance score = 100 * (total amount MOVIPREP® intake) / (planned MOVIPREP intake). Total compliance score of MOVIPREP is the average score of the compliance for the first and second litre. | 1 day (the day of colonoscopy) | 
| Patient Compliance - Amount of Additional Clear Liquid Consumed | To prevent any potential dehydration risk participants were recommended the intake of at least 500 ml of additional clear liquid (juices without pulp, tea, water) per liter of the Moviprep solution. The amount of additional clear liquid taken is reported for each liter of Moviprep taken. | 1 day (the day of colonoscopy) | 
| Percentage of Patients Who Experienced Adverse Events (AEs) | An AE was a worsening in severity or frequency of a concomitant illness or any new illness diagnosed during the clinical trial period. A serious adverse event (SAE) is any untoward medical occurrence or effect that at any dose results in death; is life threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability / incapacity; is a congenital anomaly / birth defect; is medically important. Severity is a clinical observation and describes the intensity of the event: Mild: Transient symptoms, no interference with daily activities; Moderate: Marked symptoms, moderate interference with daily activities; Severe: Considerable interference with daily activities. Relatedness to study drug was assessed by the Investigator. | From first dose of study drug until the end of colonoscopy procedure, maximum of 24 hours. |
