Impact of Dietary Fiber Supplementation on Colonic Mucosal Microbiome

Benign Colorectal Neoplasm Clinical Trial

Official title: Changes in Colonic Microbiome With Fiber Supplementation

Status Recruiting

Clinical Trial Summary

This clinical trial tests whether daily fiber supplementation will change the mucosal microbiome of the colon. The microbiome are microorganisms that live in the human gut. They serve a vital role in maintaining health. Certain microbial strains are associated with the growth of colon polyps, which eventually could go on to form colon cancer. Giving dietary fiber supplements may help prevent precancerous polyps from ever developing.

Clinical Trial Description

PRIMARY OBJECTIVE:

I. To identify how diet, specifically fiber supplementation, alters the microbiome of the colonic mucosa.

OUTLINE:

Patients receive dietary fiber orally (PO) once daily (QD) for 28 days. Patients may undergo standard of care proctoscopy or anoscopy with biopsy on study and at follow-up or may undergo standard of care colonoscopy on study. All patients also undergo collection of blood samples on study and at follow up. ;
