Colorectal Cancer and Pre-Cancerous Adenoma Non-Invasive Detection Test Study

This phase 3 clinical trial (CRC-PREVENT) was a blinded, prospective, cross-sectional study to support a premarket approval application for a class III medical device. Subjects were recruited onto the clinical trial if they were average-risk subjects, or had a self-reported family history of CRC, aged 45 and older. All participants completed the ColoSense test, which incorporated a commercially available fecal immunochemical test (FIT), concentration of 8 RNA transcripts, and participant-reported smoking status. Stool samples were collected prior to participants completing a colonoscopy at their local endoscopy center. The ColoSense test result (positive or negative) was compared with index lesions observed on colonoscopy. The primary outcomes included ColoSense sensitivity for detecting colorectal cancer, advanced adenomas, or serrated precancerous lesions, and ColoSense specificity for all other findings.
