In more than 1500 patients from 13 European countries, Pons et al. demonstrated that secukinumab retention rates after four years were approximately 50% in both axSpA and PsA patients. Pons et al. aimed to assess retention rates and proportions of patients achieving remission and LDA, according to disease activity measures and patient-reported outcomes at 24 and 48 months, in axSpA and PsA patients initiating secukinumab. In this large real-world study, Pons et al., for the first time, report 48-month retention rates as well as rates of remission and LDA. Importantly, b/tsDMARD naïve patients demonstrated higher retention, remission and LDA rates than patients with prior b/tsDMARDs exposure, particularly in axSpA.  

Merola et al. undertook a post hoc analysis of prospective cohorts that compared the effects of deucravacitinib vs placebo and vs apremilast on joint pain, and the impact of musculoskeletal symptoms, at Weeks 16 and 24 in the pooled POETYK PSO-1 and PSO-2 populations who self-reported joint symptoms on the PASE questionnaire. Patients who screened positively for PsA reported greater improvements in joint pain and peripheral joint disease with deucravacitinib vs placebo at Week 16 and vs apremilast at Week 24. Findings from this pooled analysis suggest that deucravacitinib may be used to treat both dermatologic and joint symptoms effectively in patients with psoriasis and probable arthritis.

Maksymowych et al. evaluated the effect of ixekizumab and adalimumab versus placebo over 52 weeks on structural lesions in sacroiliac joints assessed by MRI in patients naive to biological DMARDs with radiographic axSpA from the COAST-V study. The authors reported a decrease in erosion and increase in backfill at Week 16 with further reductions in erosion and increases in backfill occurring at Week 52 in patients receiving ixekizumab.

Reinisch W, et al. report that the efficacy of RZB induction therapy is independent of CS use, with high rates of CS-free outcomes observed in the overall population and among patients with baseline CS use.

March 2025

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.

Panaccione et al. investigated the association between achievement of endoscopic remission following induction therapy and hospitalisation outcomes in Crohn’s disease. Patients achieving endoscopic remission at Week 12 experienced a 55% reduction in Crohn’s disease-related hospitalisation rates over the 52-week maintenance period. The results support endoscopic remission as an early therapeutic target.

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.
