Post-hoc analysis of two tofacitinib phase three studies concludes that tofacitinib treatment resulted in improvements in enthesitis in patients with PsA, regardless of baseline location or severity.

Phase IIb study of brepocitinib in patients with PsA concludes that treatment with brepocitinib 30 mg and 60 mg QD, was superior to placebo at reducing signs and symptoms of PsA and was well-tolerated over 52 weeks.

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.
