Study Summary

This phase I trial studies how well dolcanatide works in preventing colorectal cancer in healthy participants. Dolcanatide is similar to a natural hormone released into the intestine. It is thought that people who have low levels of the hormone are more likely to get colon cancer. It may be possible to prevent colon cancer by giving a drug that is similar to the hormone, such as dolcanatide.

Primary Outcome

Pharmacological effect on cyclic guanosine monophosphate (cGMP) levels for dolcanatide arm versus (vs.) placebo, where this effect is defined as the arithmetic difference in mean cGMP levels before and after 7 days of dolcanatide from subject biopsies. This represents the increase in cGMP stimulated by 7 days of dolcanatide in an individual subject. The mean cGMP value will be calculated based on 6 biopsies collected from the rectum during a flexible sigmoidoscopy procedure. Each biopsy was anal
