Information about Guselkumab
Guselkumab is human monoclonal antibody to interleukin-23 and is used to treat severe psoriasis.
Guselkumab is associated with a low rate of transient and asymptomatic serum enzyme elevations during therapy, but has not been linked to cases of idiosyncratic, clinically apparent liver injury.
Mechanism of action of Guselkumab
Guselkumab (gue" sel koo' mab) is a human monoclonal immunoglobulin G1 antibody to interleukin (IL)-23, a cytokine that is an important mediator of autoimmune reactions. IL-23 is found in the skin lesions of psoriasis and in the affected gastrointestinal mucosa of patients with inflammatory bowel disease. Although similar, guselkumab is directed to the p19 subunit of IL-23 whereas ustekinumab is directed at the p40 subunit which is a component shared by both IL-23 and IL-12. As a consequence, guselkumab has a more restricted activity in the Th17 immune pathways which are considered to play a major role in autoimmune reactions.
FDA approval information for Guselkumab
Guselkumab was approved for use in United States in 2017, and current indications are limited to moderate-to-severe plaque psoriasis, although it is under active investigation as therapy of several other autoimmune diseases.
