Efficacy was assessed in randomised controlled trials. For safety, cohort studies, case–control studies and long-term extensions (LTEs) were analysed.Results 56 publications (efficacy: n=33; safety n=23) were analysed. The articles were on tumour necrosis factor (TNF) inhibitors (n=6; golimumab, etanercept and biosimilars), interleukin (IL)-17A inhibitors (n=10; ixekizumab, secukinumab), IL-23-p19 inhibitors (n=2; guselkumab, risankizumab), clazakizumab (IL-6 inhibitor), abatacept (CD80/86 inhibitor) and ABT-122 (anti-TNF/IL-17A), respectively. One study compared ustekinumab (IL-12/23i) with TNF inhibitor therapy in patients with entheseal disease. Three articles investigated DMARD tapering. Trials on targeted synthetic DMARDs investigated apremilast (phosphodiesterase-4 inhibitor) and Janus kinase inhibitors (JAKi; tofacitinib, filgotinib). Biosimilar comparison with bio-originator showed non-inferiority. Safety was evaluated in 13 LTEs, 9 cohort studies and 1 case–control study investigating malignancies, infections, infusion reactions, multiple sclerosis and major cardiovascular events, as well as efficacy and safety of vaccination. No new safety signals were identified; however, warnings on the risk of venous thromboembolic events including pulmonary embolism when using JAKi were issued by regulators based on other studies.Conclusion Many drugs in PsA are available and have demonstrated efficacy against placebo. Efficacy varies across PsA manifestations. Safety must also be taken into account. This review informed the development of the European League Against Rheumatism 2019 updated PsA management recommendations.
