Longitudinal Performance of Epi proColon

Epi proColon is blood based screening test for colorectal cancer that is FDA - PMA approved.
It is indicated for average risk patients who are unwilling or unable to be screened with
other recommended screening tests, including colonoscopy or fecal occult blood tests.

The PERT study is designed to assess the test performance of Epi proColon when it is used
annually for two consecutive years. Subjects enrolled in the study will be offered initial
testing. Subjects with a positive result will be referred for colonoscopy. Subjects with a
negative test result will be encouraged to be screened the following year. At the one year
interval, test negative subjects will be reminded to be rescreened. Subjects with a positive
test will be referred for colonoscopy, while subjects with a negative test will be be
encouraged to participate in a screening program in subsequent years.

Inclusion Criteria:

- Average-risk subjects (no family history of colorectal cancer (CRC), no personal
history of polyps or CRC).

- Subjects who have a history of non-compliance for CRC screening.

- After proper counseling by a health care provider, subjects who declined colonoscopy
and FIT testing.

- Subjects who are 50 years of age or greater, but less than 75 years old.

- Subjects who are able to understand and sign written informed consent (IC).

Exclusion Criteria:

- Subjects defined as having elevated risk for developing CRC based on previous history
of colorectal polyps, CRC or related cancers, inflammatory bowel disease (IBD).

- Subjects with a family history of CRC, particularly with two or more first degree
relatives with CRC, or one or more first degree relative(s) less than 50 years of age
with CRC.

- Subjects who have been diagnosed with a relevant familial (hereditary) cancer
syndrome, such as familial adenomatous polyposis (FAP) or non‐polyposis colorectal
cancer (HNPCC or Lynch Syndrome), 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, or Familial Hyperplastic
Polyposis, or in patients with anorectal bleeding, hematochezia, or with known iron
deficiency anemia.

- Subjects who are up to date for CRC screening (FOBT within preceding 12 months,
flexible sigmoidoscopy or double contrast barium enema within 5 years, or colonoscopy
within 10 years).

- Subjects with comorbid illness precluding endoscopic evaluation (coronary artery
disease with myocardial infarction within 6 months, unstable angina or congestive

diseases that limit life expectancy to less than 10 years).

- Subjects with chronic gastritis, or who have cancer other than colorectal, or pregnant
