Effectiveness and safety of brodalumab in the treatment of plaque, scalp and palmoplantar psoriasis: A multicentre retrospective study in a Spanish population

Background and Objective: The data in clinical practice regarding the effectiveness and safety of brodalumab in psoriasis are scarce, especially at scalp and palmoplantar locations. The main objective was the percentage of patients achieving absolute PASI <= 3/ <= 1/ <= 0 for plaque psoriasis and the percentage of patients achieving an IGA 0-1/ IGA 0 for the special locations at Week 52 of treatment. Patients and Methods: Observational retrospective multicentre study in 28 Spanish Hospitals that included adult patients with plaque psoriasis treated with brodalumab, from September 2018 until March 2021. Results: A total of 200 patients were included. The mean baseline PASI was 10.97 (+/- 6.28) with a mean basal scalp (n = 58) and palmoplantar (n = 40) IGA of 2.10 (+/- 0.97) and 2.15 (+/- 1.26), respectively. At Week 52, 93.98%/75.90%/68.67% of patients reached an absolute PASI <= 3/ <= 1/ <= 0 in plaque psoriasis (n = 83), with a percentage of patients achieving scalp (n = 27) and palmoplantar (n = 19) IGA 0-1/IGA 0 of 96.3%/88.9% and 100%/88.9%, respectively. Fifteen per cent of patients reported any adverse events with candidiasis being the most reported (6%), but only 6% of the adverse events required the withdrawal. Conclusions: Brodalumab demonstrated high PASI and IGA responses and was well tolerated in clinical practice in plaque, scalp and palmoplantar psoriasis.
