Abstract

Introduction: Psoriatic arthritis (PsA) is a complex, polygenic immune-mediated disease with varying clinical presentations involving the skin, nails, entheses, and axial/peripheral skeleton. Areas covered: Pathophysiology of PsA with special focus on IL-23/IL-17 axis. Novel classes of targeted therapies for PsA. Pharmacologic properties, efficacy and safety of guselkumab, the only FDA approved agent from IL-23p19 inhibitor class. Data regarding other IL-23 inhibitors (Ustekinumab–an IL-12/IL-23p40 inhibitor, Risankizumab and Tildrakizumab–both IL23p19 inhibitors), in the treatment of PsA. Expert opinion: There are seven classes of FDA-approved therapies for the treatment of PsA. IL-23p19 inhibitors are the newest class of medications that has shown efficacy and reasonable safety profile in the treatment of PsA in phase 2 and phase 3 studies; Guselkumab is the only FDA-approved biologic for PsA within this class. While no head-to-head studies of IL-23p19 inhibitors and other PsA targeted therapies are available, the efficacy of these agents on musculoskeletal system appears to be comparable to TNF-inhibitors (TNFi), and the efficacy on the skin appears to be comparable, or modestly superior to the IL-17 inhibitors (IL-17i). With a superior safety profile compared to TNFi and IL-17i, IL-23p19 inhibitors have the potential to become a first-line biologic in the treatment of PsA.
