Clinical Utility of Guselkumab in the Treatment of Moderate-to-Severe Plaque Psoriasis.

Psoriasis is a chronic immune-mediated disease involving complex interaction of T cells and keratinocytes. The comprehensive pathogenesis of psoriasis is not fully understood but the IL-23/Th17 axis is a central pathway in driving disease development. Guselkumab is the first treatment of moderate-to-severe psoriasis that specifically targets the p19 subunit of IL-23. The benefit of guselkumab has been established by a number of clinical trials including demonstration of greater long-term efficacy in recent comparator trials. This review addresses the results of head-to-head trials (ECLIPSE, IXORA-R, and POLARIS) that compared guselkumab to secukinumab, ixekizumab, and fumaric acid esters. The previously demonstrated long-term efficacy of guselkumab has been corroborated by many recently published studies. The effective and safe profile, convenient dosing, and improved quality of life in patients make gulselkumab a viable first-line treatment option for moderate-to-severe psoriasis.
