Abstract

Abstract: Background/Aims: Evidence for the efficacy of biologics in patients with oligoarticular psoriatic arthritis (PsA) is limited. We evaluated the efficacy of the interleukin 17 inhibitor secukinumab in patients with oligoarticular PsA pooled from 5 phase 3 studies. Methods: This post hoc analysis included patients with oligoarticular PsA from the FUTURE 2-5 and MAXIMISE trials (NCT01649375, NCT01989468, NCT02294227, NCT02404350, and NCT02721966). Oligoarticular PsA was defined as the presence of 1-4 tender joints and 1-4 swollen joints at baseline as measured by the tender joint count of 78 joints (TJC78) and the swollen joint count of 76 joints (SJC76), respectively. Patients were pooled by treatment received at week 12 and week 52 in the following groups: week 12 (secukinumab 300 mg, secukinumab 150 mg with or without loading dose [LD], or placebo) and week 52 (any secukinumab 300 mg or any secukinumab 150 mg). Efficacy was assessed by the proportion of patients achieving 50% improvement in Disease Activity in Psoriatic Arthritis (DAPSA50), DAPSA75, DAPSA-based low disease activity (LDA; DAPSA ≤14) and remission (REM; DAPSA ≤4), resolution of TJC78, resolution of SJC76, and a ≥ 0.35-point improvement in the Health Assessment Questionnaire-Disability Index score. Descriptive statistics are provided for each endpoint. Logistic regression analysis was used to identify potential predictors of DAPSA response at weeks 12 and 52; multivariate logistic regression analyses were performed thereafter. Results: 84 patients were included: 48 with active PsA from the FUTURE 2-5 trials and 36 with active PsA and axial manifestations from the MAXIMISE trial. Demographics and baseline disease characteristics were comparable across groups. At week 12, notable improvements were observed for the secukinumab 300 and 150 mg versus placebo groups across all the assessed outcome measures and were sustained or increased through week 52. More than 78% of patients who received secukinumab 300 mg or secukinumab 150 mg achieved LDA or REM at week 12. More than 90% of patients who received any secukinumab 300 mg or secukinumab 150 mg achieved LDA or REM at week 52. At week 52, a higher proportion of patients who received any secukinumab 300 mg versus any secukinumab 150 mg achieved higher hurdle endpoints of DAPSA75 (58.1% versus 43.6%, respectively) and DAPSA REM (61.3% versus 37.5%, respectively). At week 12, younger age was a predictor for the achievement of DAPSA LDA or REM and the achievement of DAPSA50, while lower baseline SJC was a predictor of the achievement of DAPSA REM (P < 0.05). No predictors were identified at week 52. Conclusion: Secukinumab provides greater improvements versus placebo across a number of disease activity and physical function outcome measures in patients with oligoarticular PsA at week 12, with sustained responses through week 52.
