Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Icotrokinra is a peptide that selectively binds to the IL-23 receptor (IL-23R) with a dissociation constant of 7 pM and antagonizes the binding of IL-23. IL-23 is a naturally occurring cytokine that is involved in inflammatory and immune responses. Icotrokinra inhibits the IL-23/IL-23R-dependent release of proinflammatory cytokines. 12.2 Pharmacodynamics Icotrokinra reduced serum levels of proinflammatory cytokines, IL-17A, IL-17F, IL-19, IL-22 and β-defensin-2, relative to pretreatment levels in evaluated subjects with moderate-to-severe plaque psoriasis based on exploratory analysis of the pharmacodynamic markers.
