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.

Marzo-Ortega et al. report that dactylitis and enthesitis are associated with a greater disease burden and worse prognosis, highlighting the importance for physicians to identify these conditions and provide adequate treatment. Authors evaluated guselkumab’s efficacy on dactylitis resolution (DR) and enthesitis resolution (ER), and their impact on subsequent disease control, in patients with active PsA and prior inadequate response to tumour necrosis factor inhibitors (TNFi-IR).

Lindner et al. report that their findings underscore the need for sex-specific treatment strategies and more comprehensive research into biological and sociocultural factors influencing therapy persistence and reasons for discontinuation in real-world settings. Authors investigated sex differences in treatment outcomes, persistence, discontinuation reasons, and adverse events during first-line b/tsDMARD therapy.

In this first global clinical study of a nanobody in inflammatory arthritis, sonelokimab, an
IL-17A- and IL-17F-inhibiting nanobody demonstrated strong efficacy across multiple domains including high-hurdle composite joint and skin responses. McInnes et al. reported on the Phase 2, randomized, double-blind, PBO-controlled ARGO trial which evaluated the efficacy and safety of sonelokimab in patients with active PsA.

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.

Cardiovascular safety of systemic psoriasis treatments: A prospective cohort study in the BIOBADADERM registry

This study by Lluch-Galcerá et al. provides valuable RWE to inform personalized clinical decision-making in the treatment of PsO. Authors evaluated the incidence of MACE associated with each systemic treatment used for patients with PsO and compared these rates to those observed with MTX.

Treatment with risankizumab provides durable improvement in the signs and symptoms of PsA across all the GRAPPA disease domains and related conditions. This post hoc analysis by Coates et al. aimed to assess the efficacy of long-term treatment with risankizumab across the updated GRAPPA domains and key related conditions of PsA.

Most patients vaccinated with RZV while using UPA 15mg QD and background MTX achieved satisfactory humoral and cell-mediated immune responses to recombinant zoster vaccine (RZV) at Weeks 4, 16 and 60. Winthrop et al. evaluated the immunogenicity of RZV through Week 60 in patients with RA who were receiving UPA 15mg QD and background MTX.

This descriptive analysis indicates a long-term safety profile of UPA consistent with previous reports, further supporting long-term treatment of chronic diseases with UPA. Burmester at al. characterized the safety profile of UPA across multiple approved indications and offer insights into its long-term use to help inform clinical decision-making.

This study by Sobotkova et al. confirmed the similar efficacy and overall safety of biological treatment for psoriasis in older and younger adult patients. Authors compared a large cohort of older adults during the first year of biological treatment for psoriasis to younger adult patients with similar characteristics to advance knowledge about the biologic treatment of psoriasis in older patients.
