Mease et al. showed that guselkumab provided significantly higher rates of clinical improvement and significant inhibition of structural damage progression versus PBO, with no new safety signals, at Week 24 in biologic-naïve participants with active and erosive PsA. Mease et al. report primary efficacy and safety results for the double-blind PBO-controlled phase (Weeks 0-24) of the 3-year APEX study.

This study by Lee et al. is the first to evaluate the association between adalimumab dosing intervals and uveitis recurrence in patients with AS. Authors investigated whether extending the dosing interval of adalimumab influences the recurrence of uveitis in AS patients with a history of AU who are on adalimumab therapy.

This study by Olivares-Guerrero et al. provides comparative safety data from a clinical practice point of view, potentially contributing to facilitate the drug selection process for clinicians. New biologic treatments have a superior safety profile in real-world practice compared to adalimumab and its biosimilars. Olivares-Guerrero et al. used data from the BIOBADADERM registry of AEs to analyse the long-term safety profile of systemic treatments, including biological agents as well as new small oral molecules approved for the treatment of moderate-to-severe PsO, using adalimumab and its biosimilars as comparators.

June 2025

Vermeire et al. provides data that supports the long-term efficacy and safety of obefazimod 50mg QD, with a substantial proportion of patients achieving clinical remission at Weeks 48 and 96. Vermeire et al. evaluated the 2-year outcome data of an OLM study, which assessed the long-term safety and efficacy of obefazimod 50mg QD.

The concept of difficult-to-treat disease in rheumatology: where next?

Lancet Rheumatol. 2025;7:e274–89 doi: 10.1016/S2665-9913(24)00340-0

Nagy et al. propose a unifying and holistic framework for understanding and addressing the concept of difficult-to-treat (D2T) disease across rheumatology, integrating cross-disciplinary evidence and recommending its incorporation into future disease management strategies. The D2T state requires a comprehensive, holistic, multidisciplinary approach that considers the specific characteristics of each disease and the personalised needs of the patient.

March 2025

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.

Armstrong et al. evaluated the long-term safety and efficacy of deucravacitinib in patients with moderate to severe plaque psoriasis over a three-year period. The study found that exposure-adjusted incidence rates of AEs remained stable or declined over time, with no new safety signals emerging. Clinical response rates, including PASI75/90, were maintained, supporting the drug’s long-term efficacy.

Edwards et al. reported that in patients with RA who achieved sustained LDA or remission, tapering baricitinib from 4mg to 2mg allowed most to maintain LDA at 96 weeks. Rescue with 4mg restored control for the majority, demonstrating the feasibility of dose reduction with recovery potential for treatment.
