The tumor necrosis factor (TNF) inhibitors have set a high clinical standard for the treatment of psoriatic arthritis (PsA) that is challenging for emerging therapies to surpass. However, several newer therapies have made advances in the PsA market in recent years with the availability of the first interleukin (IL)-12/23 inhibitor, the first IL-17 inhibitor, and the first oral phosphodiesterase-4 inhibitor. With the goal of achieving minimal disease activity (MDA), rheumatologists use efficacy scores such as ACR20 and HAQ-DI to guide their prescription decisions. They also need to monitor for any drug-related side effects because most of the PsA therapies increase the risk of infection and malignancy. In this content, we identify key treatment drivers, discuss the safety signals that will alarm drug prescribers, create a simulation model that mimics rheumatologists’ prescribing rationale to project the market of a new therapy, and uncover three areas of unmet need in the PsA market.
