Colorectal Cancer | Other: All eligible subjects will provide blood for SEPT9 biomarker testing |
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.

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.
