This is a 36 week dietary intervention pilot study to evaluate the effects of lyophilized black raspberries on rectal polyp burden and biomarkers in subjects with FAP. Subjects will undergo a colonoscopy or sigmoidoscopy before study treatment to determine eligibility for the study. Eligible participants will undergo a sigmoidoscopy at 36 weeks after the initation of study treatment. The size and number of rectal polyps will be documented on a code sheet and by photograph. The efficacy outcome will include the percentage reduction in the number of rectal polyps between baseline and 36 weeks.

Further study details as provided by The Cleveland Clinic:

Primary Outcome Measures:
  • To determine whether daily exposure of Black Raspberries reduces the number of rectal polyps in subjects with FAP. [ Time Frame: 36 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Biomarker indices from biopsies of normal rectal mucosa, polyps and aberrant crypt foci will be evaluated at baseline and 36 weeks to determine if black raspberries modulate their activity. [ Time Frame: 36 weeks ] [ Designated as safety issue: Yes ]
