A Study to Evaluate the Safety and Effectiveness of the Augmented Endoscopy System for Mucosal Lesion Detection During Colonoscopy for Colon Rectal Cancer.


About this study

The purpose of this study is to confirm the performance of the CB-17-08 software as a medical device (SaMD) to help endoscopist during the colonoscopy procedure to find potential mucosal lesions, including polyps, adenomas and carcinomas, without significant noise disturbing the endoscopist attention, nor negative interference with the lesions detection than with the standard endoscopy video alone. The study will evaluate whether high-definition white-light (HDWL) colonoscopy using CB-17-08 SaMD will have a lower miss rate of clinically significant polyps, as compared to standard HDWL colonoscopy alone (the current standard of care for colonoscopy).
