Overview

This study is being conducted to evaluate the safety and effectiveness of MSP01-T, a new bowel cleansing agent, in adults who are scheduled to undergo a colonoscopy. Participants will be randomly assigned to receive either MSP01-T or a comparator product. The study will assess how effectively MSP01-T cleans the bowel before the procedure and monitor any potential side effects. Adults aged 19 years and older who are planning to have a colonoscopy may be eligible to take part.

Colonoscopy is a widely used diagnostic and screening procedure for colorectal diseases. Adequate bowel cleansing is essential for the accuracy and safety of the procedure. MSP01-T is a new bowel cleansing agent developed to improve patient compliance and cleansing quality while minimizing side effects. This phase 3, randomized, single-blind, multicenter, active-controlled, non-inferiority clinical trial is designed to evaluate the efficacy and safety of MSP01-T compared to an existing standard bowel preparation. Participants will be randomly assigned to receive MSP01-T or a comparator product before undergoing a colonoscopy. The primary objective of this study is to assess the quality of bowel preparation as evaluated by endoscopists using a standardized scoring system. Secondary objectives include patient-reported tolerability, safety assessments including adverse events, and overall satisfaction. Adults aged 19 years and older who are scheduled for a colonoscopy may be eligible to participate in this study.
