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.

Zavoriti and Miossec explored the impact of tofacitinib on inflammation and coagulation in RA. Tofacitinib reduced synovial and vascular inflammation by inhibiting IFNɣ, IL-17A, and IL-6 production but failed to prevent the prothrombotic effects of inflammatory cytokines on endothelial cells. These findings suggest that while tofacitinib reduces inflammation, it does not mitigate associated thrombotic risk.

Pacheco et al. demonstrated that, compared with axSpA patients who respond to secukinumab,  patients who do not respond show increased IL-17A-producing cells and have a more pronounced type 1 IFN signature, indicating a larger inflammatory burden.

Kristensen et al. compared 14 PsA drugs across five treatment classes, evaluating their real-world effectiveness over three months. Ixekizumab showed rapid effectiveness on joint disease activity and skin outcomes, performing better than IL-12/23i and IL-23i, and comparable to TNFi and JAKi. More patients with active psoriasis achieved minimal disease activity with Ixekizumab than other therapies.

Guselkumab treatment exhibited generally comparable and significant pharmacodynamic effects on IL-23/Th17–associated cytokines across participants with PsA who are biologic-naïve or have TNFi-IR. In coming to this conclusion, investigators assessed and compared immunologic differences and associations with clinical response to guselkumab in participants with active PsA who were biologic-naïve or TNFi-IR.

This retrospective analysis by Weddell, et al. found no difference in IL-17Ai (secukinumab and ixekizumab) survival rates and no relationship between PsA or axSpA diagnosis and drug survival. They also noted lower survival figures at 2 years of treatment.

Phase 2a study assessing the efficacy and safety of tildrakizumab in patients with active AS fails to meet the primary endpoint.

Secukinumab, an IL-17A monoclonal antibody, was shown to have remarkable efficacy for axSpA in the MEASURE 2 and MEASURE 3 trials. Previous studies have concluded that secukinumab was more efficacious in TNFi-naïve patients.

Bimekizumab may therefore offer patients with axSpA an effective treatment option with a novel mode of action.
