Baraliakos et al. compared real-world effectiveness of upadacitinib, TNF inhibitors, or IL-17 inhibitors following inadequate response to an initial TNF inhibitor in patients with axSpA. Upadacitinib was associated with greater reductions in pain and fewer affected joints compared with switching to a second TNF inhibitor or IL-17 inhibitor.

Biologic switching in psoriatic arthritis: Insights from real-world data and key risk factors

Semin Arthritis Rheum. 2025;73:152737 doi: 10.1016/j.semarthrit.2025.152737

Haddad et al. used real-world data from Israel’s largest health maintenance organisation to investigate predictors and patterns of biologic therapy switching in PsA, reporting that nearly half of biologic users switched therapy at least once. Cross-class switching, particularly from anti-TNF to IL-17 therapies, was frequent and consistent across two decades of treatment data.

Kaya et al. reported that switching to secukinumab or cycling to another TNFi after first TNFi failure in axSpA led to comparable drug survival, with predictive factors differing by treatment. The study reports that smoking and Achilles enthesitis were associated with higher SEC discontinuation, while high CRP and primary TNFi failure predicted TNFi discontinuation.

Miyazaki et al. investigated the efficacy and safety of switching to bDMARDs versus cycling among JAKis in RA patients with inadequate JAKi response. Cycling to another JAKi proved more effective in improving disease activity at 26 weeks compared to switching to a bDMARD, and both groups had similar safety profiles.

Gladman et al. assessed the impact of bimekizumab over 1 year on patient-reported symptoms, HRQoL, and work productivity in patients with PsA who were bDMARD-naïve or TNF-IR. The study showed that bimekizumab treatment resulted in sustained improvements across multiple domains, including pain, fatigue, physical function, and work impairment.

Following discontinuation of secukinumab 150mg or 300mg, a proportion of patients sustained low PASI with clear or almost clear skin despite being drug free for up to 2 years. Patients with a shorter disease duration were less likely to relapse, further supporting the hypothesis that earlier intervention with secukinumab may result in long-term control of moderate-to-severe psoriasis.

July 2024

Genetic variants in TNFα, NLRP3, MYD88, and FcRγ genes were associated with a response to TNFi, when assessing several inflammatory diseases together. Al-Sofi et al. conducted a systematic review and meta-analysis on single nucleotide polymorphism (SNP) genetic markers and their response to biologics in psoriasis, PsA, RA, IBD, and across all chronic inflammatory diseases together.

More RA patients on upadacitinib versus adalimumab achieved clinical remission, LDA, and DAS28 (CRP) <2.6. Radiographic progression was less with continuous upadacitinib versus continuous adalimumab. Upadacitinib showed similar safety to adalimumab, with higher incidences of HZ, lymphopenia, CPK elevation, hepatic disorder and nonmelanoma skin cancer.

In this letter to the editor, Papp, et al. reported that brodalumab treatment in patients with psoriasis and an inadequate response to another biologic resulted in high rates of complete skin clearance with concurrent improvements in patient-reported outcomes after 26 weeks. The mean and median times to PASI 100 were 96.8 and 112 days, respectively.

April 2024

Patients treated with guselkumab showed an improved and sustained clinical response compared to both adalimumab and placebo, without compromising safety profile. The Phase 3 VOYAGE 2 trial by Reich et al focused on treatment interruption and withdrawal, as well as treatment switching from adalimumab to guselkumab.
