The purpose of this study is to collect blood specimens and clinical data from screening guideline eligible individuals designated by their physician to receive a screening colonoscopy, and to evaluate the performance of a colorectal cancer-specific DNA methylation biomarker for detection of colorectal cancer in this cohort. Based on the outcome of the colonoscopy, polypectomy, biopsy and surgical tissue histopathology, the clinical utility of Septin 9 as colorectal cancer screening test will be evaluated.

Condition Intervention
Colorectal Cancer
Other: All eligible subjects will provide blood for SEPT9 biomarker testing

Further study details as provided by Epigenomics, Inc:

Primary Outcome Measures:
  • Clinical/surgical diagnosis of invasive colorectal adenocarcinoma detected by optical colonoscopy and confirmed by histology compared to the Septin 9 Biomarker classification. [ Time Frame: One Year ]

Secondary Outcome Measures:
  • Detection of adenomatous polyp(s) equal to or greater than 10 mm, flat lesion (s) or non-invasive adenocarcinoma by colonoscopy and confirmed by histology compared to the Septin 9 Biomarker classification will also be described. [ Time Frame: One Year ]

Biospecimen Retention:   Samples With DNA
Eligible consented Subjects meeting inclusion / exclusion criteria will have 40 ml of blood drawn prior to undergoing bowel cleansing in preparation for screening colonoscopy. Subject blood specimens will be processed according to Epigenomics' plasma preparation procedure (Blood Collection and Plasma Preparation SOP.

Enrollment: 7929
Study Start Date: June 2008
Study Completion Date: April 2010
Primary Completion Date: January 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Adults > 50 Years Scheduled for Colonscopy
Average to increased risk adults older than 50 years without symptoms indicative of CRC and designated for colonoscopy.
Other: All eligible subjects will provide blood for SEPT9 biomarker testing
A single blood sample per participant selected according to analysis plan is tested for evidence of methylation of a specific DNA sequence, SEPT9.
Other Names:
  • biomarker
  • blood
  • colorectal cancer
  • DNA methylation

Detailed Description:

The study is designed as a prospective, open enrollment clinical investigation involving multiple clinical study sites in the United States and Germany. Subjects will be competitively enrolled at multiple sites until at least 50 invasive colorectal adenocarcinoma cases identified by screening colonoscopy and verified by clinical and histopathological examination have been enrolled. The primary objective of the investigation is to evaluate and describe the clinical performance of the Septin 9 Biomarker for detecting the 50 individuals with invasive colorectal adenocarcinoma identified in this population representative of the US screening guideline eligible population. Secondary objectives will be to evaluate and describe performance characteristics of the biomarker in individuals with adenomatous polyps 10 mm or larger, flat lesion (s) or non-invasive adenocarcinoma.

Collaborating sites will identify and contact patients scheduled for screening colonoscopy. These patients may be screened by the PI or designee to determine the patients' appropriateness for, and interest in, study participation. Study site personnel will meet with patients meeting eligibility guidelines and offer them participation. Patients interested in participation and who provide written informed consent will be enrolled as Subjects in the study.


Ages Eligible for Study:   50 Years and older   (Adult, Senior)
