Psoriatic Arthritis | Current Treatment: Physician Insights | US | 2018

Several new drugs have recently entered the PsA market, including new entries into the biologic disease-modifying antirheumatic drug (bDMARD) and targeted synthetic disease-modifying antirheumatic drug (tsDMARD) classes. However, the impact of these newer therapies on the treatment algorithm is not yet understood; the data in this report provide insight into this question. Physicians are choosing among six tumor necrosis factor (TNF) inhibitors, including a biosimilar version of Remicade, but they may also select from two interleukin-17 (IL-17) inhibitors, an IL-12/23i, a phosphodiesterase-4 inhibitor (PDE4) inhibitor, a Janus kinase (JAK) inhibitor, and a selective costimulation modulator. With this plethora of drugs, understanding what choices physicians make and why they prefer or avoid certain drugs is increasingly important for manufacturers.


  • How do dermatologists and rheumatologists differ in their approach to treating PsA? How many patients have received a previous diagnosis of a related disease?
  • Where in the treatment algorithm will new therapies such as Taltz, Xeljanz, and Orencia fall?
  • What factors drive physicians to switch patients away from the heavilyused TNF inhibitors? How many TNF inhibitors will be tried for a given patient before physicians move to an alternative class of therapy?
  • Under what circumstances will physicians select a biosimilar TNF inhibitor instead of a branded version? How important is cost when making prescribing decisions?
