Clinical Trial Summary

The objective of this pilot study is to compare the effectiveness of mailed outreach of two stool based tests, Cologuard and the fecal immunochemical test (FIT) in screening eligible adults ages 45-49 receiving care at the University of California San Diego Health system.

Description:

Adults ages 45-49 who are insured, deemed average risk and not currently up to date with colorectal cancer screening will be enrolled. Eligible participants will be randomized to either mailed Cologuard outreach, facilitated by Exact Sciences or mailed FIT outreach. Colorectal cancer screening completion within 3 months will be measured as the primary outcome, in addition to secondary recruitment and intervention-based feasibility outcomes to demonstrate the potential for a larger randomized controlled trial.

Intervention

Diagnostic Test:
• Cologuard
Multi-target stool DNA test for colorectal cancer screening implemented by Exact Sciences. Cologuard has 94% sensitivity and 87% specificity to detect colorectal cancer.
• Fecal Immunochemical Test
Stool blood test for colorectal cancer screening. FIT has 75% sensitivity and 90% specificity to detect colorectal cancer.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of Colorectal cancer screening completion	The proportion of individuals who complete any colorectal cancer screening test recommended by US Preventive Services Task Force (colonoscopy, FIT, Cologuard, Sigmoidoscopy or CT Colonography)	Within 3 months of randomization
Primary	Proportion of Abnormal stool blood test results	Among those completing designed interventions (Cologuard or FIT), the proportion of test results yielding an abnormal result.	Within 3 months of randomization
Primary	Proportion of Follow-up colonoscopy after abnormal stool blood test result	Among those with positive stool blood test results, the proportion who complete diagnostic follow-up colonoscopy	Within 6 months after stool blood test completion
Secondary	Number of participants opting out of the pilot	Measurement of feasibility of pilot	Within 3 months of randomization
Secondary	Number of participants with undeliverable FIT or Cologuard tests (mail fail rate)	Measurement of feasibility of mailed outreach	Within 3 months of randomization
Secondary	Number of Adenomas detected	Measurement of number of adenomas detected during study period	Within 6 months after screening test completion
Secondary	Number of sessile serrated lesions detected	Measurement of number of sessile serrated lesions detected during study period	Within 6 months after screening test completion
Secondary	Number of colorectal cancer cases detected	Number of colorectal cancers detected during study period	Within 6 months after screening test completion
