Drug survival, discontinuation rates, and safety profile of secukinumab in real-world patients: a 152-week, multicenter, retrospective study

Background Psoriasis is a chronic systemic disease that requires long-term management. Despite data on follow-up studies going back 5 years, little is known about the condition's sustainability based on patient profiles. The aim of this study was to analyze drug survival and discontinuation rates for secukinumab treatment under real-world conditions. Patients and Methods Patients with moderate-to-severe plaque psoriasis treated in the dermatology department of five Spanish medical centers between 2015 and 2019 were included in our retrospective study. Drug survival was assessed with Kaplan-Meier analysis plots and multivariate regression. Results In total, 171 treated patients were retrospectively recorded and analyzed for 152 weeks (37.40% had been diagnosed with psoriatic arthritis [PsA]). The discontinuation rate in the PsA group was 14.10% vs. 12.10% among those who had no PsA. The mean survival time of discontinuation was 63 weeks for PsA vs. 65 weeks for no PsA (P = 0.913). Secukinumab's estimated mean survival in PsA patients was 86% (estimated mean survival time 130 weeks) vs. 88% (estimated mean survival time of 133 weeks) in non-PsA patients (P = 0.676). Conclusion The mean survival time of patients in secukinumab treatment was comparable in all patient profiles and better than the data found in clinical trials and real-life studies.
