Guselkumab, a Selective Interleukin-23 p19 Subunit Inhibitor, Resolves Dactylitis in Patients With Active Psoriatic Arthritis: Pooled Results Through Week 52 From Two Phase 3 Studies
ACR Open Rheumatol. 2023 doi 10.1002/acr2.11537 Epub ahead of print
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.

Multidomain Efficacy and Safety of Guselkumab Through 1 Year in Patients with Active Psoriatic Arthritis with and Without Prior Tumor Necrosis Factor Inhibitor Experience: Analysis of the Phase 3, Randomized, Placebo-Controlled DISCOVER-1 Study
ACR Open Rheumatol. 2023 doi: 10.1002/acr2.11523
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.

Guselkumab was approved for treating the signs and symptoms of active PsA following two Phase 3 global studies, DISCOVER-1 and DISCOVER-2. The Phase 3b APEX study has been designed to address the limitations of DISCOVER-2 and further assess the effects of guselkumab Q4W and Q8W on PsA outcomes.

Guselkumab provides sustained domain-specific and comprehensive efficacy using composite indices in patients with active psoriatic arthritis
Rheumatology (Oxford) 2022 doi: 10.1093/rheumatology/keac375
This analysis found that patients with active PsA who receive treatment with guselkumab can achieve robust and sustained low disease activity or remission. In reaching this conclusion investigators sought to evaluate the efficacy of guselkumab for the treatment of active PsA through the use of composite indices.
