Brodalumab (Kyntheum)
Brodalumab is a recombinant fully human monoclonal immunoglobulin IgG2 antibody that binds with high affinity to human IL-17RA and blocks the biological activities of the pro-inflammatory cytokines IL-17A, IL-17F, IL-17A/F heterodimer and IL-25, resulting in inhibition of the inflammation and clinical symptoms associated with psoriasis. IL-17RA is a protein expressed on the cell surface and is a required component of receptor complexes used by multiple IL-17 family cytokines. IL-17 family cytokine concentrations have been reported to be increased in psoriasis. Blocking IL-17RA inhibits IL-17 cytokine-induced responses resulting in normalisation of inflammation in the skin.
