Exact CRC Screening Test: Stool Sample Collection Study to Support Assay Validation Testing

May 12, 2015 updated by: Exact Sciences Corporation
The objective of this study is to confirm the sensitivity and specificity of a stool DNA test for detection of colorectal cancer and pre-cancer.

Study Overview

Detailed Description

Patients who have recently undergone a colonoscopy that resulted with normal findings will be asked to submit a stool sample (s) (at least 30 days AFTER colonoscopy).

Study Population

Patients are at average risk of developing colorectal cancer at the time of their colonoscopy and the colonoscopy resulted in normal findings.

Description

Inclusion Criteria:

  • Subject is male or female, 50-84 years of age, inclusive.
  • Subject is at average risk for development of CRC and has undergone a screening colonoscopy with a normal result at least 30 days and no more than 120 days before providing a stool sample for the study. For the purposes of this study, a "normal" colonoscopy result is defined as no polyps of any size detected or removed (including benign, hyperplastic polyps).
  • Subject is able to understand the study procedures, and is able to provide signed consent to participate in the study and authorizes release of relevant protected health information through signing a HIPAA consent.
  • Subject is able and willing to provide stool samples at least 30 days and no more than 120 days after undergoing a colonoscopy that resulted in normal findings, according to the written instructions provided to them.

Exclusion Criteria:

  • Subject has any condition which, in the opinion of the investigator should preclude participation in the study.
  • Subject had any findings on recent or any previous colonoscopy including benign, and/or hyperplastic polyps of any size. (Note: Tissue biopsies that result in no histopathology findings are acceptable.)
  • Subject has a history or recent diagnosis of CRC or adenoma.
  • Subject has a history of aerodigestive tract cancer.
  • Subject has had a positive fecal occult blood test or FIT within the previous six (6) months.
  • Subject has had a prior colorectal resection for any reason other than sigmoid diverticular disease.
  • Subject has had 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.
    • Greater than or equal to (>=)2 first-degree relatives who have been diagnosed with colon cancer. (Note: first-degree relatives include parents, siblings and offspring).
    • One first-degree relative with CRC diagnosed before the age of 60.
    • 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.
