Introduction Brodalumab is a recombinant monoclonal antibody (IgG2) that binds with high affinity to the human interleukin‐17 (IL‐17) receptor A and blocks the biological activity of the proinflammatory cytokines IL‐17A, IL‐17F, IL‐17A/F heterodimer, and IL‐ 25, resulting in inhibition of inflammation and clinical symptoms associated with psoriasis. Its introduction has managed to increase the levels of efficacy, safety (improving that previously presented by the anti‐IL‐17 class), and survival. Material and methods Retrospective analysis of a multicenter, observational study of real clinical practice including patients with moderate to severe plaque psoriasis in treatment with brodalumab. This cross‐sectional analysis includes information of patients between February 2019 and February 2022. A total of five tertiary hospitals in Andalusia (Spain) participated in this study. Analyses were performed “as observed” using GraphPad Prism version 8.3.0 for Windows. Results Our study included 85 patients, 54 men (63.5%) and 31 women (36.5%), with moderate–severe psoriasis treated with brodalumab. In order to evaluate the efficacy of brodalumab, our patients started with mean Psoriasis Area and Severity Index (PASI) values of 12.8 and body surface area (BSA) of 16.9, as well as a Dermatology Life Quality Index (DLQI) of 15.6, highlighting that they reported that the mean baseline visual analog scale (VAS) pruritus was 6.15. On week 52, mean PASI reached 1.26 and mean BSA 2.3, showing a clear stabilization and even sustained improvement regarding results on week 12. Concerning the brodalumab survival, we obtained 85.8% persistence at week 52. Discussion Brodalumab showed excellent results in the control of psoriasis in the mid‐term with an elevated number of patients maintaining treatment after 52 weeks. There were no statistically significant differences in the efficiency, safety, or survival results of brodalumab between patients coming from previous therapies.
