Prajapati et al. conducted the PROTOSTAR trial to assess guselkumab in paediatric patients with moderate-to-severe plaque psoriasis. Guselkumab significantly improved skin clearance versus placebo at Wk16, with high response rates sustained through Wk52 and a favourable safety profile.

Floris et al. conducted a monocentric cohort study to assess the impact of biologic treatment on the development of PsA in patients with PsO. Treatment with biologics significantly reduced the likelihood of PsA development, with lower prevalence observed across different biologic classes and patterns of joint involvement.

Burden and determinants of multi-b/tsDMARD failure in psoriatic arthritis

Arthritis Research & Therapy 2025;27:46 doi: 10.1186/s13075-025-03518-7

Haberman et al. analysed prescribing patterns and characteristics of PsA patients with
multi-b/tsDMARD failure, defined as requiring ≥4 b/tsDMARDs. Among 960 patients at the NYU Psoriatic Arthritis Centre, 17% met this criterion. These patients were more likely to be female, obese, and have higher rates of axial involvement and depression. They also exhibited greater disease activity, suggesting that both inflammatory and non-inflammatory factors contribute to multiple treatment failures.

Van den Bosch et al. reported that upadacitinib 15 mg once daily led to sustained improvement in nr-axSpA over two years, including disease activity, pain, and quality of life. The study reports that 57.1% achieved ASAS40 response at week 104, with no new safety signals identified.

Deodhar et al. assessed the long-term safety, tolerability and efficacy of bimekizumab in patients with r-axSpA over five years. The study found that bimekizumab maintained disease control achieved at Wk48 through Wk256, with no new safety signals observed. Adverse events were consistent with previous reports, and clinical benefits, including improvements in disease activity and patient-reported outcomes, were sustained.

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.
