Post hoc analysis of guselkumab, Phase 3 DISCOVER-1 and -2 studies finds that 75% of guselkumab-randomised patients have complete resolution of dactylitis through one year.

TNF inhibitors (TNFi) are one main mode of therapy in patients with PsA who fail to respond to csDMARDs. However, they have a primary treatment failure rate of 40% and only a modest target of ≥20% ACR20 response. The objective of this study was to evaluate efficacy and safety of guselkumab, interleukin-23 inhibitor in the DISCOVER-1 study with active PsA patients by prior use of TNFi.

Data from this paper provides a robust analysis of radiographic progression through 2 years in a phase 3 study of guselkumab in patients with PsA. This study sought to evaluate the relationship between radiographic progression and clinical outcomes in post hoc analyses of patients with PsA receiving up to 2 years of guselkumab therapy in DISCOVER-2.
