A prospective multicenter study assessing effectiveness and safety of secukinumab in a real-life setting in 158 patients.

Background: Secukinumab is a first-in-class interleukin 17A monoclonal antibody that has demonstrated an excellent safety and efficacy profile in phase 3 studies.
Objective: To evaluate the effectiveness of secukinumab in daily clinical practice and to understand the clinical and epidemiologic characteristics of patients treated with secukinumab in clinical settings.
Methods: In this multicenter prospective observational study, we recruited adult patients with moderate-to-severe plaque psoriasis from 12 hospitals in Spain during January-December 2016. These patients were treated with secukinumab and prospectively followed at 12-week intervals for 52 weeks.
Results: In total, 158 patients were recruited to the study. A Psoriasis Area and Severity Index (PASI) score improvement ≥75% over baseline (PASI-75) was achieved by 57%, 83.5%, 89%, and 78.5% of patients at weeks 4, 12, 24, and 52, respectively. PASI-90 was achieved in 27.8%, 62%, 64.6%, and 63.2% of patients at weeks 4, 12, 24, and 52, respectively; PASI-75 and PASI-90 responders were significantly more common among patients with a body mass index <30 kg/cm ² and patients without previous biologic therapy failures.
Limitations: Observational study. Time from onset of psoriasis was not evaluated.
Conclusion: Secukinumab is a safe treatment with effectiveness rates similar to those found in its phase 3 studies. These rates endure up to a year from start of treatment.
