FULL SUPPLEMENT: Brodalumab: Five Years of Real-World Safety and Efficiency

Psoriasis remains a highly prevalent condition in the United States and worldwide. Preclinical research has been triumphant in elucidating the critical immunological pathways involved in psoriasis. There has been an evolution in biologics that paralleled the understanding of these pathways beginning with anti-tumor necrosis factor (TNF) inhibitors and now most recently the interleukin (IL)-23 and IL-17 axes. Numerous evidence-based studies demonstrate the efficacy of these agents for skin clearance in moderate-to-severe plaque psoriasis. Brodalumab, a fully humanized IL-17 receptor A (IL-17RA) antagonist, is wholly unique in that it binds to a cytokine receptor and not a cytokine itself unlike the other biologics indicated for psoriasis. This unique mechanism has lent an advantage where not only is brodalumab effective in treating moderate-to-severe plaque psoriasis, but it is also successful in psoriasis patients whose disease did not respond to other biologics. This review provides a summary of the efficacy of brodalumab in plaque psoriasis and difficult-to-treat locations (ie, scalp, nail, palmoplantar), in patients with psoriasis who failed to achieve minimum clearance with other biologics, and it illuminates the most recent pharmacovigilance data obtained from the past 5 years. Furthermore, the cost effectiveness of brodalumab is also discussed.
