Background: Brodalumab is a monoclonal antibody and IL-17 RA inhibitor that is approved for the treatment of moderate-to-severe psoriasis. The present study aims to estimate the drug survival (DS), effectiveness, and safety of brodalumab over a period of 156 weeks. Methods: The primary objectives were: (i) to determine the treatment response rate at Weeks 16, 28, 52, 78, 104, and 156 as defined by PASI100, PASI90, and an absolute PASI ≤ 3 and (ii) long-term DS. Secondary objectives included the evaluation of possible predictive factors associated with the achievement of response outcomes, and possible predictive factors associated with lower DS. Results: The treatment response was rapid, with 80.3% of patients achieving PASI ≤ 3, 66% PASI90, and 54.3% the complete clearance of disease at Week 16. The response improved at Week 28, when a plateau was achieved with mild loss of response at later time points, in particular for PASI100 and PASI90 in 55.2 and 65.5% of patients, respectively, at Week 156. After 156 weeks of treatment, 66.22% of patients were still on therapy, and the previous use of IL-17 inhibitors appeared to be associated with an increased risk of treatment discontinuation (HR: 2.51, CI: 1.06-5.98, P = 0.037), and achievement of PASI ≤ 3 until Week 16 with less risk (HR: 0.27 CI: 0.14-0.51, P < 0.001). Bio-naïve status was favorably associated with treatment response, while high BMI negatively affected the achievement of outcomes. Conclusion: Our study confirms the good effectiveness and favorable safety profile of brodalumab in a real-world setting over up to 3 years of treatment.

Abstract

Background: Brodalumab is a monoclonal antibody and IL-17 RA inhibitor that is approved for the treatment of moderate-to-severe psoriasis. The present study aims to estimate the drug survival (DS), effectiveness, and safety of brodalumab over a period of 156 weeks. Methods: The primary objectives were: (i) to determine the treatment response rate at Weeks 16, 28, 52, 78, 104, and 156 as defined by PASI100, PASI90, and an absolute PASI ≤ 3 and (ii) long-term DS. Secondary objectives included the evaluation of possible predictive factors associated with the achievement of response outcomes, and possible predictive factors associated with lower DS. Results: The treatment response was rapid, with 80.3% of patients achieving PASI ≤ 3, 66% PASI90, and 54.3% the complete clearance of disease at Week 16. The response improved at Week 28, when a plateau was achieved with mild loss of response at later time points, in particular for PASI100 and PASI90 in 55.2 and 65.5% of patients, respectively, at Week 156. After 156 weeks of treatment, 66.22% of patients were still on therapy, and the previous use of IL-17 inhibitors appeared to be associated with an increased risk of treatment discontinuation (HR: 2.51, CI: 1.06-5.98, P = 0.037), and achievement of PASI ≤ 3 until Week 16 with less risk (HR: 0.27 CI: 0.14-0.51, P < 0.001). Bio-naïve status was favorably associated with treatment response, while high BMI negatively affected the achievement of outcomes. Conclusion: Our study confirms the good effectiveness and favorable safety profile of brodalumab in a real-world setting over up to 3 years of treatment.
