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.

Ferrante et al. conducted a phase 3 trial evaluating the efficacy and safety of mirikizumab in patients with moderately-to-severely active Crohn’s disease. The study demonstrated that mirikizumab significantly improved clinical and endoscopic outcomes compared with placebo at week 52, with a favourable safety profile and tolerable adverse events.

McInnes et al. assessed the efficacy of guselkumab over 48 weeks in patients with psoriatic arthritis who had an inadequate response to TNF inhibitors. The results demonstrated consistent improvements in joint, skin, and patient-reported outcomes across all baseline-defined subgroups. Guselkumab showed greater efficacy compared with placebo at Week 24, with responses maintained or improved through Week 48.

Tsai et al. conducted a systematic literature review and network meta-analysis evaluating deucravacitinib and other systemic treatments for moderate-to-severe plaque psoriasis in Asian populations. The authors reported that deucravacitinib achieved PASI75 and PASI90 response rates of 66% and 40%, respectively, higher than placebo and apremilast.

December 2024

Alarfaj et al. demonstrate fenofibrate significantly improved clinical outcomes, inflammatory biomarkers, and quality of life in patients with mild-to-moderate UC when added to mesalamine therapy.
