Sponsor's own description

Colon polyposis (the presence of multiple colon polyps) is very common with Cowden syndrome, as over 60% of patients have 50 or more polyps. In a previous clinical trial, some participants had reduction in the number of colon polyps with the use of the medication sirolimus for a very short time period. This study is investigating sirolimus and its effect on the number of colon polyps in patients with Cowden syndrome and polyposis over a 1 year period.
