The manifestations of PsA are driven by disregulation of multiple pro-inflammatory cytokines3-17

Human silhouette illustrating the 6 key domains of psoriatic arthritis: skin psoriasis, axial disease, nail psoriasis, enthesitis, dactylitis, and peripheral arthritis

When treating psoriatic arthritis, consider the value of a medication that impacts the 6 key domains19

Visual representation based on clinical and preclinical evidence.

DMARD, disease-modifying antirheumatic drug; IFN, interferon; IL, interleukin; TNF, tumor necrosis factor; Th, T helper.
