Novel Regimen of IL-17A Inhibitor Secukinumab for the Remission of Severe Hidradenitis Suppurativa: Case Report.

Hidradenitis suppurativa (HS) is a morbid, recurrent skin condition that presents a major challenge to clinical therapy. Investigation into the pathogenesis of HS has implicated local and systemic pro-inflammatory cytokines, particularly TNF-α and IL-17A, as major determinants of disease progression and severity. This has ushered in a revolution in HS therapy with biologics targeting these cytokines. We report a case of a 36-year-old man with extensive and treatment-resistant Hurley Stage 3 HS. After undergoing numerous unsuccessful trials of topical, systemic, and biologic therapies, secukinumab therapy with 150 mg weekly injections was initiated. HS clinical response was seen after 20 weeks and was maintained for almost two years. Secukinumab 150 mg or 300 mg once weekly may be an effective and safe therapeutic option for moderate-to-severe chronic HS. J Drugs Dermatol. 2022;21(12):1358-1360. doi:10.36849/JDD.6752.
