Efficacy of Tofacitinib on Enthesitis in Patients with Active Psoriatic Arthritis: Analysis of Pooled Data from Two Phase 3 Studies
Arthritis Res Ther. 2023 22;25(1):153 doi: 10.1186/s13075-023-03108-5
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.
Efficacy and Safety of the TYK2/JAK1 Inhibitor Brepocitinib for Active Psoriatic Arthritis: A Phase IIb Randomized Controlled Trial
Arthritis Rheumatol. 2023;75(8):1370–1380 doi: 10.1002/art.42519
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.
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.
Comparative Performance of Composite Measures From Two Phase III Clinical Trials of Ixekizumab in Psoriatic Arthritis
RMD Open. 2022 doi: 10.1136/rmdopen-2022-002457
In this latest investigation into ixekizumab more patients achieved targets assessed by mCPDAI and DAPSA than with other composites. This study assess’ the concordance and variability in performance of the composite measures in patients with PsA, as well as to provide greater granularity to the frequency and severity of residual symptoms in patients who achieve treatment targets.
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.
Efficacy and Safety of Filgotinib, a Selective Janus Kinase 1 Inhibitor, in Patients with Active Psoriatic Arthritis (EQUATOR): Results from a Randomised, Placebo-controlled, Phase 2 Trial
Lancet. 2018 Dec 1;392(10162):2367-2377. DOI 10.1016/ S0140-6736(18)32483-8In this first clinical trial of filgotinib in patients with PsA, filgotinib was effective in treating the signs and symptoms of active PsA across various disease manifestations.The EQUATOR trial was a randomized, double-blind, placebo-controlled, Phase 2 trial, that enrolled 191 adult patients from 25 sites in seven countries. Patients with active moderate-to-severe PsA and an insufficient response or intolerance to at least one csDMARD were assigned 1:1 to receive filgotinib 200 mg or placebo o...
