Real-Life Data of Secukinumab in Patients with Moderate to Severe Plaque Psoriasis, Psoriatic Arthritis, and Ankylosing Spondylitis: Patient Baseline Characteristics Data from the PROMPT Study

Abstract

Introduction: Secukinumab has proven to be effective and safe in psoriasis (PsO), psoriatic arthritis (PsA), and ankylosing spondylitis (AS) in the phase 3 studies. However, data on real-world practice is limited. Methods: This study is an ongoing, multicenter, 2-year observational study that focuses on patients with moderate to severe plaque PsO, active PsA, or AS receiving secukinumab. The aim of this study is to present baseline data for the entire study population. Results: A total of 127 patients were enrolled, with 101 having PsO, 12 with PsA, and 14 with AS. Among the patients, approximately 54.0% were male. The mean body mass index ranged from 25.0 to 27.4 kg/m2 across all groups. Patients with PsO had the longest disease duration with an average of 11.0 years, followed by AS (3.0 years) and PsA (1.0 year). Previous biologic therapy was observed in 6.9–8.1% of patients. Baseline disease severity scores revealed moderate to severe disease. In the PsO group, the mean Psoriasis Area and Severity Index score was 16.1. For patients with PsA, the mean Tender Joint Count was 9.1, and the mean Swollen Joint Count was 6.7. In the AS group, the mean Bath Ankylosing Spondylitis Disease Activity Index score was 4.6, and the mean Ankylosing Spondylitis Disease Activity Score was 3.7. Conclusion: The study demonstrates disease durations, disease activity, and treatment history in Thai patients that were generally consistent with previous randomized controlled studies. Long-term data on the efficacy and safety of the treatment will be presented in future publications.
