selectively
targets IL-231

TREMFYA® selectively targets and binds with high specificity and affinity to IL-231-3

Watch the video below to see the mechanism of action

TREMFYA® is the only fully human anti–IL-23

  • IL-23 is a naturally occurring cytokine that is involved in normal inflammatory and immune responses1
  • Interaction between IL-23 and its receptor drives the differentiation, proliferation, and survival of Th17 cells, which produce inflammatory cytokines4-6
  • By blocking IL-23, TREMFYA® inhibits the release of important pro-inflammatory cytokines and chemokines4-6
    • In evaluated subjects with plaque psoriasis, guselkumab reduced serum levels of IL-17A, IL-17F, and IL-22 relative to pretreatment levels based on exploratory analyses of the pharmacodynamic markers
    • In evaluated subjects with psoriatic arthritis, serum levels of acute phase proteins, C-reactive protein, serum amyloid A and IL-6, and Th17 effector cytokines IL-17A, IL-17F, and IL-22 were elevated at baseline. Serum levels of these proteins measured at Week 4 and Week 24 were decreased compared to baseline following guselkumab treatment at Week 0, Week 4, and every 8 weeks thereafter
  • The clinical significance of these findings is not known

The mean half-life of guselkumab in patients with plaque psoriasis: ~15 to 18 days1
