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.

Effectiveness of Sequential Lines of Biologic and Targeted Small Molecule Drugs in Psoriatic Arthritis: A Systematic Review

Rheumatology (Oxford). 2024 Jan 18:keae006 doi: 10.1093/rheumatology/keae006 Epub ahead of print

The authors found that there is a reduction in effectiveness of lines of bDMARDs after first-line in PsA, with inadequate data to determine response to tsDMARDs.

Cardiovascular Safety of Janus Kinase Inhibitor Therapy in a Multi-ethnic Population

Musculoskeletal Care 2023 doi 10.1002/msc.1853 Epub ahead of print

This study by Sunmboye, et al. investigated the relationship between CV event incidence and age in a multi-ethnic population that received JAK inhibitor therapy. They concluded that JAK inhibitor therapy was generally safe in a multi-ethnic population with a large age range, but they did find a statistically significant but numerically small positive correlation between age and CV incidence

This post hoc analysis by Curtis, et al. found that current and former smokers were more likely to switch from an anti-TNF bDMARD to a different bDMARD or JAK inhibitor in comparison to non-smokers. They also found that DAS28(CRP) ≤3.2 achievement was significantly higher after filgotinib therapy regardless of smoking status in MTX-IR, bDMARD-IR, and MTX-naïve patients.

In this two-round modified RAM study by Solitano, et al., the authors found that experts preferred to assess JAK inhibitor risk on a case-by-case basis across all specialties. Uncertainty remained on several clinical scenarios regarding the appropriate use of JAK inhibitors, however they remain an important therapy option for the treatment of IMIDs  and were deemed appropriate for patients with moderate risk profiles.

Siderius, et al. found that secukinumab was associated with low spinal radiographic progression. Furthermore, bone-related outcomes and BTMs related to collagen resorption (sCTX, PINP) remained constant during the 2-year period, whereas the BTM related to mineralisation (BALP) decreased significantly.

Nationwide study involving 14 778 new users of targeted therapies with PsA found treatment persistence to be lower for women than men for TNFi and IL17i but not for IL-12/23i, IL-23i or JAK inhibition.

This monocentric, retrospective clinical study by Mastorino, et al. found that ixekizumab demonstrated efficacy an safety in patients with PsA and PsO for up to five years. Being a super-responder was significantly associated with a lower rate of discontinuation, while high BMI was associated with a lower achievement of more than one PSAI measure up to Week 104.

The Risk Factors for Uveitis Among Psoriatic Arthritis Patients: A Population-based Cohort Study

Clin Rheumatol. 2023;43(3):1053–1061 doi: 10.1007/s10067-023-06834-y

Retrospective matched cohort study concludes that PsA is associated with increased risk of uveitis, with past uveitis and treatment with etanercept being independently associated with a higher risk of uveitis. Patients who developed uveitis were mainly treated with topical glucocorticoids.

This systematic literature review and network meta-analysis provides evidence for bimekizumab being an efficacious option in the management of both b/tsDMARD-naïve and experienced patients across the axSpA spectrum, with similar safety and tolerability to existing treatments.
