Abstract
INTRODUCTION: In DISCOVER-2, guselkumab, an interleukin-23 p19 subunit inhibitor, was efficacious in biologic-naïve psoriatic arthritis (PsA) patients. We report the effect of guselkumab on health-related quality of life (HRQoL) using the EuroQol 5-Dimension 5-Level (EQ-5D-5L) Index and Visual Analog Scale (EQ-VAS) through Week 52.
METHODS: Adults with active PsA were randomized to guselkumab 100 mg every 4 weeks (Q4W) or Weeks 0, 4, then every 8 weeks (Q8W), or placebo (crossover to guselkumab Q4W at Week 24). Least squares (LS) mean changes in EQ-5D-5L Index (0-1, US-based value set) and EQ-VAS (0-100) from baseline through Week 52 were assessed. Proportions of patients achieving minimally important differences (MIDs) were assessed through Week 52. Associations between patient clinical features and EQ-5D-5L Index and EQ-VAS scores were examined cross-sectionally with pooled data through Week 24.
RESULTS: The analysis included 738 patients (Q4W n = 245; Q8W n = 248; placebo n = 245). At Week 24, LS mean changes from baseline in the Q4W, Q8W, and placebo groups were 0.12, 0.12, and 0.05, respectively, for EQ-5D-5L Index, and 18.2, 18.4, and 6.8, respectively, for EQ-VAS. At Week 52, improvement was maintained in the guselkumab groups and increased in the placebo crossover group. EQ-5D-5L Index MID was achieved by 56.0% in each guselkumab group at Week 24 and 66.2% in Q4W, 68.5% in Q8W, and 66.1% in placebo crossover group at Week 52. Higher C-reactive protein level, Psoriasis Area and Severity Index score, fatigue, and pain were correlated with worse EQ-5D-5L Index and EQ-VAS, based on pooled data through Week 24. Higher tender joint count was correlated with worse EQ-5D-5L, while higher swollen joint count was correlated with worse EQ-VAS.
CONCLUSIONS: Guselkumab improved HRQoL through 52 weeks in patients with active PsA. Impairment in HRQoL was correlated with increased inflammation, fatigue, pain, and measures of skin and joint symptom severity.
