Guselkumab - In Psoriasis and Beyond

Abstract

Introduction: Guselkumab is an interleukin 23p19 inhibitor, and the first in this group, to be approved by the US Food and Drug Administration (FDA) for the management of moderate to severe psoriasis. Apart from its utility in psoriasis, there are a number of other dermatologic conditions where guselkumab has demonstrated value. Objectives: The aim of this narrative review is to describe the utility of guselkumab in psoriasis as well as its implication in off-label dermatologic disorders. Methods: Pubmed, Google Scholar, Scopus and ResearchGate were searched for scholarly articles related to guselkumab and its utility in dermatology using the search terms “Guselkumab” AND “Psoriasis” AND “other dermatological disorders”. Results: Guselkumab is a valuable biologic agent for the management of psoriasis and psoriatic arthropathy. It has also been used successfully for other dermatologic disorders like hidradenitis suppurativa, lichen planus, pityriasis rubra pilaris and pyoderma gangrenosum. Recently, its utility in Stewart-Treves angiosarcoma (STA) has been exemplified. Conclusion: Guselkumab’s usage is not limited to psoriasis. Its benefit extends to many more dermatologic conditions. Its utility in STA could open an avenue for its application in the field of oncology. Furthermore, it has an acceptable safety profile.
