This large French nationwide study by Fautrel et al. provided reassuring results for patients, who initiated tocilizumab (TCZ), aged at least 75 years compared to younger patients. Authors compared patient characteristics, tolerance of RA treatments, and long-term management with TCZ in patients with RA over and under 75 years of age.

Bai et al. reported that JAKi therapy was associated with a reduced risk of incident uveitis compared with TNF inhibitors among patients with AS, PsO, or PsA. Authors conducted a large-scale, real world comparative study which evaluated the risk of incident uveitis among patients with psoriatic disease and AS treated with either TNFi or JAKi.

Ramiro et al. show that bimekizumab (BKZ) reduces enthesitis and peripheral arthritis in patients with nr-axSpA and r-axSpA up to 2 years. Authors assessed the effect of BKZ treatment on the main peripheral manifestations of axSpA, including enthesitis and peripheral arthritis, using a range of measures including DAPSA, to Week 104 in the BE MOBILE 1 and 2 studies.

Nozaki et al. showed that JAK inhibitor treatment provided sustained disease control (especially in high-risk RA patients) and promoted GC reduction, although TNF inhibitors remain a standard option. Nozaki et al. evaluated the clinical efficacy and continuation rates of JAK inhibitors and TNF inhibitors in RA patients with poor-prognosis factors (PPFs).

Hernández-Hernández et al. showed that in a real-world clinical settings, UPA persistence is lower among RA patients who have received prior IL-6i treatment; and that treatment strategies to avoid UPA in patients with cardiovascular risk (CVR) appear to be primarily driven by pivotal safety studies rather than regulatory guidance.

Xu et al. showed that elevated BMI, BSA, body weight, and basal metabolic rate are associated with more severe PsO and diminished treatment efficacy, especially for those treated with biologics. Authors investigated the associations of BMI, basal metabolic rate, BSA, and body weight with baseline PsO severity and therapeutic response across different treatment modalities.

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.

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.

Qiao et al. showed that ixekizumab demonstrated superior efficacy in mild-moderate versus severe PsO, suggesting greater benefit with early biologic intervention. Authors compared clinical efficacy, relapse rates, and drug retention between mild-to-moderate and severe plaque PsO cohorts with different severity levels treated with Ixekizumab.

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.
