An Evaluation of a Multi-target Stool DNA (Mt-sDNA) Test, Cologuard, for CRC Screening in Individuals Aged 45-49 and at Average Risk for Development of Colorectal Cancer: Act Now

The primary objective is to confirm the specificity of a multi-target stool DNA test (mt-sDNA), Cologuard, in an average risk population, ages 45-49.

Study Overview

• Status: Completed
• Conditions: Colorectal Cancer
• Intervention / Treatment: Procedure: Colonoscopy; Diagnostic test: mt-sDNA screening test

Detailed Description

Subjects aged 45-49 at average risk for development of CRC will be enrolled. Subjects will complete the mt-sDNA screening test (Cologuard) followed by completion of a screening colonoscopy. The results of the mt-sDNA screening test (Cologuard) will not be provided to investigators for clinical management of study subjects. Personnel performing the colonoscopy and producing the resulting report and personnel performing histopathological review of tissue (if applicable) will remain blinded to the results of the mt-sDNA screening test (Cologuard) result.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Specificity of the Multi-target Stool DNA Test in Average Risk Population, Ages 45-49	An optical colonoscopic procedure is the reference method. Lesions will be confirmed as malignant by histopathologic examination. Results were generated with the use of a logistic-regression algorithm, with values of 183 or more considered to be positive. Tests were processed independently of colonoscopic findings. The test functions as a screening tool by generating a score, based on the detection of hemoglobin and multiple DNA methylation and mutational markers, together with an assessment of the total amount of human DNA in each sample. Specificity =100*(multi-target stool DNA test negative/negative colonoscopy)	Through study completion, an average of 60 days
