Abstract
BACKGROUND: Psoriasis imposes a disease burden that can have a profound negative impact on patients' quality of life (QoL). HOPE was the first non-interventional study conducted in patients with severe chronic plaque psoriasis in Australia that evaluated health-related QoL in response to treatment with secukinumab. METHODS: HOPE was a prospective, open-label, single-arm, multicentre, non-interventional, exploratory study in patients with severe chronic plaque psoriasis in Australia. The study investigated the change in QoL, using the Dermatology Life Quality Index (DLQI), Assessment Quality of Life-8 Dimension questionnaire (AQoL-8D) and Psoriasis Area and Severity Index (PASI), and safety profile in response to treatment with secukinumab 300 mg SC weekly for 4 weeks followed by monthly maintenance for 58 weeks. RESULTS: At Week 14, the mean percentage reduction in total DLQI score from baseline was -82.4% (n = 65), which indicates a substantial improvement in QoL. This level of improvement was sustained up to Week ≥58, with a mean percentage change of -87.4%. The mean percentage change from baseline for AQoL-8D weighted total score decreased from Week 14 (41.1%) to Week 58 (35.2%), indicating an improvement in patients' QoL. A high proportion of patients achieved PASI 75/90/100 responses at Week 14 (97.0%/71.2%/34.8%), with rates sustained up to Week ≥58 (100%/87.9%/43.1%). The safety profile of secukinumab was favourable, with no cumulative or unexpected safety concerns. CONCLUSION: Secukinumab treatment demonstrated a striking improvement in patients' QoL in the HOPE study, the first real-world study in patients with severe chronic plaque psoriasis in the Australian clinical setting.
