Data from an international collaboration of registries show no evidence of an increase in CV events during the first 2 years of use with JAKi, compared to TNFi, in the general RA population.

Aharoni-Frutkoff et al. demonstrated that tasty & healthy (T&H) ‘diet’ showed better tolerability than exclusive enteral nutrition (EEN) for inducing remission in mild to moderate CD, while positively affecting the microbiome. Authors explored the tolerability and effectiveness of the T&H diet compared with EEN in children and young adults with mild to moderate uncomplicated CD.

Upadacitinib in psoriatic arthritis with prior TNF-inhibitor failure: a 56-week real-world study

Clin Exp Rheumatol. 2025; Advance online publication Epub ahead of print Doi: 10.55563/clinexprheumatol/gniy9i

Bakay et al. report  that upadacitinib (UPA) demonstrated sustained efficacy across musculoskeletal and skin domains in PsA patients with prior inadequate response to TNF inhibitors, with a safety profile consistent with previous reports.  Authors conducted a retrospective, single-centre observational study evaluating musculoskeletal disease activity, psoriasis, and patient-reported outcomes following initiation of UPA.

Gollins et al. reported that within this cohort, the Psoriatic arthritis response criteria (PsARC) response to 4th+ lines of b/tsDMARD was not significantly reduced compared with 2nd/3rd line in participants who had failed at least 3 b/tsDMARDs. Authors evaluated the primary clinical response to sequential lines of b/tsDMARD therapy in PsA, focusing on the effectiveness of later line treatments.

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).

Bennett et al, showed that tofacitinib treatment in adults with rheumatoid arthritis led to a significant increase in lower limb and thigh muscle volume, accompanied by rises in serum creatinine without evidence of renal impairment.

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.
