MOVIPREP® Versus PICOLAX® Pilot Study

Gut cleansing will be performed using a split dose of MOVIPREP®, 1-litre solution (1x sachet A and 1x sachet B) in the evening prior to the day of colonoscopy and 1-litre solution (1x sachet A and 1x sachet B) in the morning of the colonoscopy, or PICOLAX®, 150 mL solution (1 sachet) before 8am on day prior to the day of colonoscopy, and 150 mL solution (1 sachet) 6 to 8 hours later.

The primary efficacy measure will be the degree of gut cleansing, as assessed by the physician performing the colonoscopy. A 5-grade scale will be used to assess each of the predefined colon areas, resulting in a final grading (A to D) of the overall quality of the bowel preparation treatment. Grades A and B will be considered as success, and Grades C and D as failure.

The secondary efficacy measures will be:

• is it necessary for the patient to return for a further colonoscopy due to insufficient clearance/cleansing of colon prior to the normal schedule for a repeat procedure?
• taste acceptability
• ease of taking, and ability to complete the bowel preparation treatment
• recommended diet compliance
• would the patient be prepared to repeat the bowel preparation treatment if necessary?
• well-being and effect on usual activities whilst taking the bowel preparation treatment
• overall impression of the bowel preparation treatment prior to colonoscopy
• symptoms experienced since taking their first study bowel preparation treatment and prior to their colonoscopy

Safety and tolerability will be assessed through the collection of adverse events, clinical laboratory tests, physical examination, weight and vital signs (blood pressure and pulse rate) data.

Number of patients:

It is intended to recruit approximately 70 patients in order to achieve at least 60 evaluable patients using a randomisation ratio of 1:1 MOVIPREP®: PICOLAX®.
