Tumor necrosis factor inhibitors (TNFi) are frequently chosen as the first biologic for patients with psoriatic arthritis (PsA). Given that many PsA TNFi inadequate responders (TNF-IR; either efficacy or intolerance), treatments utilizing alternative mechanisms of action needed. In phase 3 studies, fully human interleukin (IL)-23p19 subunit-inhibitor, guselkumab, was efficacious in active PsA, including TNFi-IR. Efficacy generally consistent between TNFi-naïve and TNFi-experienced cohorts;...
