Study of the Efficacy and Safety of Quiklean® and Klean-Prep With Dulcolax® for the Bowel Preparation Prior to Colonoscopy
A Prospective, Randomized, Evaluator Blind, Active-Controlled, Parallel Study of the Efficacy and Safety of Quiklean® and Klean-Prep With Dulcolax® for the Bowel Preparation Prior to Colonoscopy

Detailed Description
This will be a randomized, evaluator blind, active-controlled, parallel study to compare the safety and efficacy of investigational drug (Quiklean®) with standard comparator (Klean-Prep with Dulcolax®) in subjects undergoing bowel preparation for colonoscopy. This study will be conducted in two arms:
- Group A: Quiklean® (32 tablets)
- Group B: 2 sachets of Klean-Prep with 1 tablet of Dulcolax® The study will be consist of 4 clinical visits. Subjects will come to the clinics at Visit 1 (the start of the screening), Visit 2 (randomization), and Visit 3 (colonoscopy visit), and Visit 4 (follow-up visit) according to the pre-defined schedule.
After the inform consent is obtained from the subject, the designated assessment will be performed. If the eligibility criteria has been met, the subjects will be randomly assigned with a 1:1 (Group A:B) and scheduled to a colonoscopy. The colonoscopy visit should be arranged within 10 days after screening visit and randomization. Subjects are instructed how to take study medication, and standard dietary instructions for each group are identical.
After bowel preparation, the colonoscopy will be performed in the morning by the experienced colonoscopist, and the entire process of colonoscopy will be simultaneously recorded by video. The quality of bowel cleansing in video will be rated by an independent blinded colonoscopist after the completion of colonoscopy.
The modified Aronchick scale for the primary efficacy endpoint and the Ottawa scale, and subject's responses to the acceptability and tolerability for the secondary efficacy endpoint will be rated and collected. The safety laboratory examinations from the blood sample, solicited events from the start of administration of study medications before colonoscopy, and treatment-emergent adverse events will be also recorded.
