Risankizumab improved health-related quality of life, fatigue, pain and work productivity in psoriatic arthritis: results of KEEPsAKE 1

Abstract

Objectives. PsA is a heterogeneous disease that impacts many aspects of social and mental life, including quality of life. Risankizumab, an antagonist specific for IL-23, is currently under investigation for the treatment of adults with active PsA. This study evaluated the impact of risankizumab vs placebo on health-related quality of life (HRQoL) and other patient-reported outcomes (PROs) among patients with active PsA and inadequate response or intolerance to conventional synthetic DMARD (csDMARD-IR) in the KEEPsAKE 1 trial. Methods. Adult patients with active PsA (n ¼ 964) were randomized (1:1) to receive risankizumab 150 mg or placebo. PROs assessed included the 36-Item Short-Form Health Survey (SF-36, v2), Functional Assessment of Chronic Illness Therapy–Fatigue (FACIT-Fatigue), EuroQoL-5 Dimension-5 Level (EQ-5D-5L), Patient’s Assessment of Pain, Patient’s Global Assessment (PtGA) of Disease Activity, and Work Productivity and Activity Impairment–PsA (WPAI-PsA) questionnaire. Least squares (LS) mean change from baseline at week 24 was compared between risankizumab and placebo. Results. At week 24, differences between groups were observed using LS mean changes from baseline in SF-36 physical component summary and mental component summary; FACIT-Fatigue; EQ-5D-5L; Patient’s Assessment of Pain; PtGA; all eight SF-36 domains (all nominal P < 0.001); and the WPAI-PsA domains of impairment while working (presenteeism), overall work impairment and activity impairment (all nominal P < 0.01). Conclusion. Risankizumab treatment resulted in greater improvements in HRQoL, fatigue, pain and work productivity in patients with active PsA who have csDMARD-IR, when compared with placebo.
