Serious Gastrointestinal-Related Adverse Events Among Psoriasis Patients Treated With Guselkumab in VOYAGE 1 and VOYAGE 2

Abstract

Background: Anti-interleukin (IL)-17 biologic agents used to treat psoriasis are associated with onset/exacerbation of inflammatory bowel disease (IBD). Objectives: To determine the incidence of IBD or serious gastrointestinal-related adverse events (GI SAEs) in patients with moderate-to-severe psoriasis treated with guselkumab, an IL-23p19 inhibitor that indirectly inhibits IL-17, through 4 years in the phase 3 VOYAGE 1 and VOYAGE 2 trials. Methods: Patients were randomized to guselkumab 100 mg every-8-weeks or placebo→guselkumab (week 16), or adalimumab. In VOYAGE 1, all patients received open-label guselkumab starting at week 52. In VOYAGE 2, eligible patients were treated with guselkumab..
