Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Mailed Cologuard Outreach

Receipt of mailed Cologuard test for colorectal cancer screening to be completed and returned by participant. If test is negative, participant will be advised to undergo another test in 3 years. If test is positive, participant will be advised to schedule colonoscopy for further testing.

Group Type EXPERIMENTAL

Cologuard

Intervention Type DIAGNOSTIC_TEST

Multi-target stool DNA test for colorectal cancer screening implemented by Exact Sciences. Cologuard has 94% sensitivity and 87% specificity to detect colorectal cancer.

Mailed Fecal immunochemical test Outreach

Receipt of mailed FIT for colorectal cancer screening to be completed and returned by participant. If test is negative, participant will be advised to undergo another test in 1 year. If test is positive, participant will be advised to schedule colonoscopy for further testing.

Group Type ACTIVE_COMPARATOR

Fecal Immunochemical Test

Intervention Type DIAGNOSTIC_TEST

Stool blood test for colorectal cancer screening. FIT has 75% sensitivity and 90% specificity to detect colorectal cancer.
