IN ACTIVE PSORIATIC ARTHRITIS
STELARA® STARTS UPSTREAM IN THE THE INFLAMMATORY CASCADE
  • STELARA® is a human IgG1k monoclonal antibody that binds with specificity to the p40 protein subunit used by both the IL-23 and IL-12 cytokines1,2
  • IL-23 and IL-12 are naturally occurring cytokines that are involved in inflammatory and immune responses, such as natural killer cell activation and CD4+ T-cell differentiation and activation2
  • In in vitro models, STELARA® was shown to disrupt IL-23 and IL-12 mediated signaling and cytokine cascades by disrupting the interaction of these cytokines with a shared cell-surface receptor chain, IL-12Rβ12
  • By targeting the upstream regulatory cytokines IL-23 and IL-12, STELARA® was shown to disrupt the resultant inflammatory cascade2
  • The clinical significance of these characteristics is not fully known
