  • Indications
  • FDA Approved
  1. Plaque Psoriasis (moderate to severe, candidates for systemic therapy or Phototherapy)
    1. Guselkumab (Tremfya)
    2. Risankizumab (Skyrizi)
    3. Tildrakizumab (Ilumya)
  2. Active Psoriatic Arthritis
    1. Guselkumab (Tremfya)

    1. Risankizumab (Skyrizi)
  • Mechanism
  1. Interleukin 23 Inhibitor (IL23 Inhibitor)
    1. The Cytokines IL-23 and IL-17 are released from activated myeloid Dendritic Cells and Macrophages
    2. Cytokines (e.g. IL-23) trigger a proinflammatory cascade, activating immune cells (e.g. T cells)
      1. Angiogenesis
      2. Keratinocyte proliferation
      3. Immune cells migrate to within psoriatic lesions
  2. IL23 Monoclonal antibodies
    1. Self-injectable agents that target IL23
    2. Suppress IL23-triggered inflammatory response
