About

This study will evaluate whether morning-only dosing of MoviPrep® (2L) for afternoon colonoscopy is as effective as a standard dosing regimen of half of the volume of MoviPrep® (1L) solution the evening prior, and half (1L) the morning of, colonoscopy. MoviPrep® is a low volume (2 liters) polyethylene glycol (PEG)-based purgative that is approved for evening-only or split (evening and morning) dosing to cleanse the colon prior to colonoscopy. Patients undergoing afternoon colonoscopies often have inferior colon cleansing. There is evidence that morning-only purgative administration of large volume PEG (4L) is safe and effective. This study will assess whether administration of a low volume PEG regimen will maintain efficacy and improve tolerance by changing a 2-day preparation procedure into a regimen that is completed in 1 day.

Full description

primary objectives

• To compare the efficacy of morning dose only MoviPrep® ("AM Dosing") where one-half of the prep is given 7 hours before colonoscopy and the second half is given 4 hours before colonoscopy, versus split dose (PM/AM) MoviPrep® ("PM/AM Dosing") where one-half of the prep is given at 6pm the night prior to colonoscopy and the second half is given 4 hours before colonoscopy.

Efficacy will be assessed based on cleansing of the entire colon, with successful cleansing defined as a score of excellent or good and unsuccessful cleansing defined as a score of fair or poor.

Secondary objectives

To assess the tolerability of AM Dosing MoviPrep® versus PM/AM Dosing MoviPrep® based on percentage of prep completed, sleep quality/quantity, future prep choice (same prep or alternative prep described), and incidence and severity (using 11-point Likert scale) of any adverse events (i.e. nausea, vomiting, abdominal pain, bloating, light-headedness).
To evaluate the safety of each dosing administration based on vitals with orthostatic measures (BP, pulse) on day of colonoscopy.
To evaluate the effect of colon prep on work and productivity as measured by the degree of interference with work/productivity the day prior to colonoscopy.
To assess difference between two dosing arms with respect to analysis of right colon cleansing, and overall adenoma detection in terms of number, size, location, histology, and morphology.
To determine the effect of purgative dosing on procedure efficiency by measuring (a) total procedure time, (b) time from anus to cecum, and (c) withdrawal time (excluding time taken for interventions).
To evaluate the effect of purgative dosing regimen on amount of flushing required during the procedure (0 = none, 1 = <50 ml, 2 = 50-100 ml, 3 = >100 ml).
To validate a new grading scale for colon cleansing using the de-identified recordings of colonoscopies performed during this study.
