Clinical Trials

The purpose is to investigate whether a simple additional treatment applied during colonoscopy (called 'soft' coagulation) can reduce the risk of recurrence of polyp at the area where the polyp was removed. After a large polyp is removed it is known that there is a 20% chance that a small recurrence of polyp occurs at the site of removal can occur within 5 months of the polyp being removed. This in theory will burn off tiny polyp tissue, which is usually not visible to the naked eye. This additional treatment may possibly reduce the risk of polyp recurrence.

This is a proof-of-concept study to evaluate the preliminary clinical activity of guselkumab in subjects with Familial Adenomatous Polyposis. The study is designed to determine if guselkumab has clinical activity in the colorectum and duodenum, by reducing the number of polyps over a period of 24 weeks.
