Real-World Experience of Secukinumab Treatment in Patients with Moderate-to-Severe Plaque Psoriasis in Greece: 3-Year Interim Results of the SERENA Study

Abstract

SERENA is an ongoing European noninterventional longitudinal study evaluating retention, effectiveness, safety, and quality of life (QoL) in secukinumab-treated patients with active moderate-to-severe plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis. Herein, 3-year interim results among patients with psoriasis enrolled in Greece are presented. Consented adults receiving secukinumab according to the approved label for ≥16 weeks were included. Of 292 patients enrolled, 290 eligible patients (mean age 48.4 years, 71.7% male) were analyzed. At treatment initiation, 65.9% of patients were biologic-naïve and mean total Psoriasis Area Severity Index (PASI) score was 29.0. At enrolment, mean treatment duration was approximately 1.0 year. The treatment retention rate at 1/2/3 years after enrolment was 94.4/87.3/85.9%; main reasons for discontinuation were lack of effectiveness and adverse events (AEs) (43.6% and 28.2% of discontinuations, respectively). At enrolment, the mean PASI score was 4.0, 61.3% of patients had PASI ≤ 3, 71.7% had Physician’s Global Assessment (PGA) score 0/1, 59.5% had Dermatology Life Quality Index (DLQI) score 0/1, while the mean EuroQoL Visual Analogue Scale (EQ-VAS) score was 82.0. At 1/2/3 years postenrolment, the mean PASI score was 1.9/1.6/1.0, 86.6/89.4/90.0% had PASI ≤ 3, 89.5/94.8/97.5% had PGA 0/1, 71.1/75.9/ 81.8% had DLQI 0/1, and mean EQ-VAS score was 85.7/90.0/92.0. Of enrolled patients, 7.2% experienced secukinumab-related AEs, while special interest AEs (candida infections, malignancy, and major adverse cardiovascular events) were reported in ≤2 patients, each. These results demonstrate high secukinumab persistence in the Greek population up to three years after study enrolment, accompanied by sustained improvements in both clinical and QoL parameters and a favorable safety profile.
