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.

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.

September 2024

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.

Results of this analysis by Blauvelt, et al. showed a low adjudicated suicidal ideation and behaviour (SIB) rate of 0.13/100 patient-years for bimekizumab, consistent with general psoriasis population ranges. Bimekizumab did not increase the risk of SIB compared to other anti-IL-17A/anti-IL-23 therapies.

Bimekizumab therapy was associated with a rapid and sustained improvement in PASI response and IGA score in patients with moderate to severe plaque psoriasis. Dual inhibition of IL-17A/F with bimekizumab can affect a more durable response in PsO patients than sole IL-17A inhibition. Gordon et al. compared the safety and efficacy of two different maintenance dosing schedules, in addition to the effects of treatment withdrawal in the 52-week BE READY trial.

Bimekizumab versus adalimumab in plaque psoriasis

N Engl J Med 2021; 385:130–41. doi: 10.1056/NEJMoa2102388

Bimekizumab was noninferior and superior to adalimumab with respect to PASI 90 response and IGA score at Week 16. Bimekizumab is a promising IL-17A/F inhibitor that has shown clinical improvement in PsO patients compared to placebo and other IL inhibitors. Warren et al. compared the safety and efficacy of bimekizumab with adalimumab in a 56-week double-blind trial.

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.

February 2024

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.
