Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years to 84 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

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.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 1, 2011

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
