Brief Summary:
This study will be a prospective analysis conducted by Geneoscopy Inc. to evaluate the ColonoSight test, which is a multi-target stool RNA test for colorectal screening.

Condition or disease Intervention/treatment Phase
Colorectal Cancer Advanced Adenocarcinoma Adenoma Colon Polyp of Colon Diagnostic Test: Colonosight Stool Sample Collection Kit Not Applicable

Detailed Description:
Patients who are eligible for a colonoscopy (i.e., asymptomatic, average risk individuals 45-84 years of age who are not up-to-date with screening guidelines) will be enrolled in the study. Stool samples returned to Geneoscopy's Laboratories by the participant will be subjected to the ColonoSight test system, and a result will be generated. The result will be compared to an optical colonoscopy to determine: 1) sensitivity for colorectal cancer, advanced adenomas, and other precancerous adenomas and 2) specificity for hyperplastic polyps and no findings on a colonoscopy. This study will be used for the clinical validation of the ColonoSight test.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 10000 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: This study will be a prospective analysis conducted by Geneoscopy Inc. to evaluate the ColonoSight test, which is a multi-target stool RNA test for colorectal screening. Patients who are eligible for a colonoscopy (i.e., asymptomatic, average risk individuals between 45-80 who are not up-to-date with screening guidelines) will be enrolled in the study. Stool samples returned to Geneoscopy's Laboratories by the participant will be subjected to the ColonoSight test system, and a result will be generated. The result will be compared to an optical colonoscopy to determine: 1) sensitivity for colorectal cancer, advanced adenomas, and other precancerous adenomas and 2) specificity for hyperplastic polyps and no findings on a colonoscopy. This study will be used for the clinical validation of the ColonoSight test.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: ColonoSight Test
All participants will be evaluated with the Colonosight Test system and a colonoscopy.
 Diagnostic Test: Colonosight Stool Sample Collection Kit
The ColonoSight Collection Kit provides information on how to collect a stool swab using a fecal immunochemical test (FIT) and how to collect a stool sample using the ColonoSight Collection Kit. After a stool sample is produced, patients will swab the stool sample using the FIT tube according to instructions and return the stool sample via mail courier to Geneoscopy's Laboratories. Patients will then be directed to receive a colonoscopy. If a lesion is removed during the colonoscopy, the tissue sample will be sent for histopathology review. The colonoscopy report and the histopathology report will be reported to Geneoscopy. Stool samples returned to Geneoscopy's Laboratories will be subjected to the ColonoSight test system, which includes targeted nucleic acid enrichment and biomarkers quantification via droplet digital polymerase chain reaction. The FIT returned in the ColonoSight Collection Kit will also be read by laboratory technologists at Geneoscopy.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. ColonoSight sensitivity for subjects with CRC [ Time Frame: 1 year ]
    ColonoSight sensitivity for subjects with CRC, which is the percentage of individuals with a diagnosis of colorectal cancer that were detected as positive by the ColonoSight test.

  2. ColonoSight sensitivity for subjects with Advanced Adenoma (AA) [ Time Frame: 1 year ]
    ColonoSight sensitivity for subjects with AA, which is the percentage of individuals with a diagnosis of advanced adenoma that were detected as positive by the ColonoSight test.

  3. ColonoSight sensitivity for subjects with high-grade dysplasia [ Time Frame: 1 year ]
    ColonoSight sensitivity for subjects with high-grade dysplasia, which is the percentage of individuals with a diagnosis of carcinoma in situ or advanced adenoma with high grade dysplasia that were detected as positive by the ColonoSight test.

  4. ColonoSight sensitivity for subjects with Other Adenomas (OAs) [ Time Frame: 1 year ]
    ColonoSight sensitivity for subjects with Other Adenomas (OAs), which is the percentage of individuals with a diagnosis of a non-advanced precancerous adenoma that were detected as positive by the ColonoSight test.

  5. ColonoSight specificity for subjects with negative findings [ Time Frame: 1 year ]
    ColonoSight specificity for subjects with negative findings, which is the percentage of individuals with a diagnosis of benign polyps, or no findings on a colonoscopy that were detected as negative by the ColonoSight test.
