Secukinumab efficacy regarding PROs and retention rate was comparable between axSpA and PsA patient groups when adjusted for confounders. Christiansen et al compared 6-, 12- and 24-month pain, fatigue, PGA, and HAQ PROs in axSpA and PsA patients treated with secukinumab, as well as 24-monthy retention rates in this real-world study.  

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 study reports that the PsAID-12 total score and individual PsAID items capturing disease concepts important to patients with PsA demonstrated robust psychometric properties.

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.

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.

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.

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 Phase 3 RCT by D’Agostino, et al. assessed the long-term effect of secukinumab to placebo at tissue level on synovitis and enthesitis, and across all PsA manifestations. They found consistent improvements in clinically and ultrasound-assessed synovitis and enthesitis.
