Summary

This study tests whether the drug guselkumab (Tremfya), with or without a low-processed-food diet, can help people with chronic pouchitis—a painful gut condition that can occur after surgery for ulcerative colitis. Twenty adults who have not responded to antibiotics will receive the drug for 48 weeks. The main goal is to see if symptoms improve after 16 weeks.
