Study Summary

This randomized phase I trial studies the side effects and best dose of linaclotide acetate in preventing colorectal cancer in healthy volunteers. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of linaclotide acetate may prevent colorectal cancer.

Primary Outcome

The pharmacological effect is measured by the arithmetic difference in mean cGMP levels before and after 7 days of linaclotide acetate in biopsies from the colonoscopy. The mean cGMP value will be calculated based on 2 biopsies from the rectum assessed at each time point. The PD response is measured by the difference in mean cGMP levels after 7 days.
