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.

Mease et al. report that patients without radiographic progression through 2 years of secukinumab treatment had greater achievement of LDA states at Week 104 than patients with radiographic progression. This post hoc analysis by Mease et al. of the FUTURE 5 study evaluated the relationship between radiographic progression status at Week 104 and achievement of LDA or remission and identified demographics and clinical characteristics that were associated with radiographic progression status at Week 104.

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.

July 2025

Brandt-Jürgens et al. identified a difference between the incidence rates of uveitis in patients with PsA or axSpA when treated with secukinumab compared to placebo. The authors conducted a post hoc analysis of 11 placebo-controlled clinical trials which has observed that uveitis incidences in patients with PsA are consistent with clinical trial data, and patients with axSpA show a lower incidence of uveitis compared to other publications.

June 2024

Ritchlin et al. conducted a post hoc analysis of the DISCOVER-2 trial, evaluating the efficacy of guselkumab in biologic-naïve patients with PsA. Guselkumab provided durable disease control across key PsA domains and PROs over 2 years, regardless of baseline characteristics. A significant proportion of patients achieved stringent endpoints such as ACR50/70, complete skin clearance, and resolution of dactylitis/enthesitis.

May 2024

FitzGerald, et al. found that Deucravacitinib significantly impacted biomarkers associated with TYK2 signalling pathways of key inflammatory cytokines, including IL-23 and Type I IFN, and those related to collagen matrix turnover.

February 2024

Bimekizumab was well tolerated in patients with PsA and TNFi-IR up to 52 weeks, with a safety profile consistent with that observed in prior studies. This study aimed to assess 52-week safety and efficacy of bimekizumab in patients with active PsA and prior IR/intolerance to TNFi.

This post hoc analysis of the SPIRIT-H2H study showed that patients with PsA that were treated with ixekizumab had significantly higher rates of symptom resolution versus adalimumab at Weeks 12 and 52 in distal interphalangeal joint disease and nail PsO.

September 2023

Data from this phase 3 RCT demonstrated that the efficacy of bimekizumab observed at 16 weeks remained consistent through to 52 weeks in the treatment of bDMARD-naïve patients with PsA. Patients who started the trial on placebo and switched to bimekizumab at week 16 showed similar improvements to those patients who were randomised to receive bimekizumab at the start of the trail. No new safety signals were identified.

Whole blood transcriptome profiling reveals differential gene expression in patients with active PsA from the DISCOVER-1 and DISCOVER-2 clinical studies in comparison with healthy controls.
