About

This study was a prospective analysis conducted by Geneoscopy Inc. to evaluate the ColoSense test, which is a multi-target stool RNA test for colorectal cancer screening.

Full description

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.

Subject is able and willing to provide stool samples within the 120 days prior to a colonoscopy procedure
Subject is able and willing to undergo a colonoscopy after providing a stool sample

Exclusion criteria

Subject had any precancerous finding on most recent colonoscopy. This does not include benign, and/or hyperplastic polyps of any size (Note: Tissue biopsies that result in no histopathology findings are acceptable)
Subject has a history or diagnosis of colorectal cancer
Subject has a history of aerodigestive tract cancer
Subject has had a positive non-invasive screening diagnostic within the associated recommended intervals:
- Fecal occult blood test or fecal immunochemical test within the previous twelve (12) months
- FIT-DNA test within the previous 36 months
Subject has had a colonoscopy in the previous nine (9) years
Subject has had a prior colorectal resection for any reason other than sigmoid diverticular disease
Indication for colonoscopy was due to overt rectal bleeding, e.g., hematochezia or melena, within the previous 30 days. (Blood on toilet paper, after wiping, does not constitute rectal bleeding)
Subject has a diagnosis or personal history of any of the following high-risk conditions for colorectal cancer:
- Inflammatory bowel disease (IBD) including chronic ulcerative colitis (CUC) and Crohn's disease
- Familial adenomatous polyposis (also referred to as "FAP", including attenuated FAP)
- Hereditary non-polyposis colorectal cancer syndrome (also referred to as "HNPCC" of "Lynch Syndrome")
- Other hereditary cancer syndromes including but are not limited to Peutz-Jeghers Syndrome, MYH-Associated Polyposis (MAP), Gardner's Syndrome, Turcot's (or Crail's) Syndrome, Cowden's Syndrome, Juvenile Polyposis, Cronkhite-Canada Syndrome, Neurofibromatosis and Familial Hyperplastic Polyposis
