Lyophilized Black Raspberries in Adults With Familial Adenomatous Polyposis (FAP)

A Pilot Study To Investigate the Biological Modulation of Familial Adenomatous Polyposis (FAP) by Lyophilized Black Raspberries

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 initiation 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.

Inclusion Criteria:

• Diagnosis of familial adenomatous polyposis with at least 5 rectal polyps which are greater than or equal to 2 mm on baseline colonoscopy
• Have an endoscopically assessable rectal segment
• Have not taken NSAIDs or selective COX-2 inhibitors for two months prior to the study and willing to remain off NSAIDs for the study duration.

Exclusion Criteria:

• Known allergies or hypersensitivity to berries
• Diabetes mellitus
• Subjects taking NSAIDs or COX-2 inhibitors who cannot be taken off the medication due to their clinical condition.
