Retention rate of secukinumab in psoriatic arthritis: Real-world data results from a Spanish multicenter cohort.

ABSTRACT: Secukinumab is a novel anti-IL17 biologic treatment approved for the treatment of psoriatic arthritis (PsA). The purpose of the present study is to identify factors that can condition the retention rate of this drug in a real-world scenario. Methods: A multicentric retrospective study was conducted based on the registries of consecutive patients diagnosed with PsA who started secukinumab from January 2016 to December 2018. For purposes of Cox-regression analysis, the time spanning from the first administration of secukinumab until its interruption or the end of the follow-up was considered the independent variable. Variables of known relevance and those who demonstrated direct association with the drug retention rate were included in the model. Results: One hundred seventy-six registries were analyzed (average age at diagnosis 44.7 ± 12.1 years old, 114 females). The median retention rate of secukinumab was 636 days (95% confidence interval [CI] 542.4-729.5). Presence of peripheral arthritis (hazard ratio 0.424 [95% CI 0.213-0.847, P = .015]) and a time of evolution >6 years (hazard ratio 0.468 [95% CI 0.225-0.975, P = .043]) were the 2 variables that showed a significant influence on the drug retention rate. According to our results, patients who exhibit peripheral arthritis and those with a higher evolution time will have more probabilities of a larger secukinumab retention rate.

Project description:BackgroundRandomized clinical trials have demonstrated the efficacy of secukinumab (SECU) in reducing disease activity in psoriatic arthritis (PsA), while real-world studies prove a broader perspective on SECU's usefulness in everyday clinical practice.ObjectivesTo assess the effectiveness of SECU by evaluating drug survival and identifying potential predictors of clinical response and treatment discontinuation in patients with moderate-to-severe PsA, using real-world data from the Italian Group for the Study of Early Arthritis (GISEA) registry.DesignThis longitudinal retrospective study included PsA patients treated with SECU, spanning from May 2016 to November 2023.MethodsData from 1045 PsA patients, including 783 with peripheral-only PsA (perPsA) and 262 with peripheral and axial involvement (mixed PsA) were analyzed. Drug survival was estimated by Kaplan-Meier analysis. Clinical outcomes, including Disease Activity Index for Psoriatic Arthritis (DAPSA), Psoriasis Area Severity Index (PASI), Ankylosing Spondylitis Disease Activity Score (ASDAS, C-Reactive Protein (CRP)-based), and Visual Analogue Scale (VAS) measures, were evaluated at baseline and at 6, 12, and 24 months. Adjusted hazard ratios (aHRs) for discontinuing SECU were determined using multivariate Cox regression models.ResultsSECU survival at 24 months was 63.24%, significantly higher in mixed PsA compared to perPsA (p = 0.036). In the overall PsA population, DAPSA scores decreased significantly at 6 months, and further at 24 months (all p < 0.0001). In mixed PsA, ASDAS-CRP scores were significantly reduced at 6 months and remained stable through 24 months (all p < 0.0001). VAS pain scores also improved already at 6 months and continued to improve at 24 months (all p < 0.0001). Higher age (aHR = 0.98, 95% confidence interval (CI): 0.96-0.99, p = 0.007) and lower baseline DAPSA scores (aHR = 1.02, 95% CI: 1.01-1.03, p = 0.014) were associated with greater persistence of SECU treatment. SECU was well tolerated, with no serious adverse events.ConclusionSECU showed sustained clinical improvements in both peripheral and axial involvement of PsA patients over 24 months, with higher persistence observed in mixed PsA patients. Our findings highlight the favorable clinical and safety profile of SECU in real world.
