  • 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

  • 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:

    multi-target stool RNA test

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. CRC Sensitivity

    ColoSense sensitivity for subjects with colorectal cancer (CRC), which is the percentage of individuals with a diagnosis of CRC that were detected as positive by the ColoSense test.

    Measured: Through study completion, an average of 5 years.

  2. AA Sensitivity

    ColoSense sensitivity for subjects with advanced adenomas (AA), which is the percentage of individuals with a diagnosis of AA that were detected as positive by the ColoSense test.

    Measured: Through study completion, an average of 5 years.

  3. SPL Sensitivity

    ColoSense sensitivity for subjects with serrated precancerous lesions (SPL), which is the percentage of individuals with a diagnosis of SPL that were detected as positive by the ColoSense test.

    Measured: Through study completion, an average of 5 years.

  4. NEG Specificity

    ColoSense specificity for subjects with negative findings, which is the percentage of individuals with a diagnosis of negative findings that were detected as negative by the ColoSense test.

    Measured: Through study completion, an average of 5 years.
