Abstract

OBJECTIVE: To investigate the impact of sustained low disease activity (LDA)/remission (REM) on physical function, quality of life (QoL) and structural outcomes in secukinumab-treated psoriatic arthritis (PsA) patients from the FUTURE 5 study.

METHODS: FUTURE 5 was a randomised, double-blind, placebo-controlled, parallel-group, phase 3 study in patients with active PsA. Patients were categorised according to LDA (Minimal Disease Activity, MDA/Disease Activity index for Psoriatic Arthritis, DAPSA LDA+REM) or REM (very LDA/DAPSA REM): not achieving LDA/REM, achieving it once or sustained LDA/REM ≥3 times up to week 104. Key outcomes were improvements in Health Assessment Questionnaire Disability Index and Short Form-36 Physical Component Summary Score, proportion of non-radiographic progressors and predictors of sustained LDA response.

RESULTS: Patients were randomised (N=996) into the following treatment groups: secukinumab 300 mg (N=222), secukinumab 150 mg loading (N=220)/non-loading (N=222) and placebo (N=332). Baseline characteristics were comparable between patients with sustained DAPSA and MDA responses. By week 104, 48%-81% and 19%-36% of the secukinumab-treated patients achieved sustained LDA and REM, respectively. Numerically greater improvements in physical function and QoL were observed with sustained LDA/REM versus LDA/REM achieved once or not at all, although patients reached the established minimal clinically important difference for all composite indices. A high proportion of secukinumab-treated patients were non-structural progressors at 2 years irrespective of achieving sustained LDA/REM. Younger age, lower body mass index at baseline, reduced tender joint count and PsA pain at week 16 were key predictors of sustained LDA in secukinumab-treated patients.

CONCLUSION: Sustained LDA/REM was associated with improvements in physical function, QoL and inhibition of structural damage progression.
