RESUMEN
Biologic therapy is used for systemic treatment of multiple inflammatory conditions, including moderate-to-severe plaque psoriasis. Brodalumab is an interleukin-17 (IL-17) receptor A antagonist indicated for the treatment of moderate-to-severe plaque psoriasis in adult patients who are candidates for systemic therapy or phototherapy and have failed to respond or have lost response to other systemic therapies. The unique mechanism of action of brodalumab, which blocks signaling mediated by multiple IL-17 family members, may play a key role in the overall efficacy, including in patients whose disease did not respond to other biologics. In this narrative review, we discuss the mechanism of action of brodalumab in inflammatory skin conditions, exploring how it relates to clinical and real-world efficacy, rescued responses after IL-17A inhibitor failure, and improvements in mental health and quality of life.
