ABSTRACT: BACKGROUND:To explore the effect of abatacept treatment on patient-reported outcomes (PROs) in psoriatic arthritis (PsA). METHODS:Patients with PsA were randomised (1:1) to subcutaneous abatacept 125?mg weekly/placebo for 24?weeks with early escape (EE) to open-label abatacept (week 16). Adjusted mean changes from baseline to weeks 16 (all patients) and 24 (non-EE responders) in Health Assessment Questionnaire-Disability Index (HAQ-DI), Short Form-36 (SF-36; physical and mental component summary and domains), Dermatology Life Quality Index and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) were evaluated. Subpopulations were analysed by baseline C-reactive protein (CRP) level (> vs???upper limit of normal [ULN]) and prior tumour necrosis factor inhibitor (TNFi) exposure. Proportions of patients reporting improvements ? minimal clinically important differences (MCIDs) and???normative values (NVs) in HAQ-DI, SF-36 and FACIT-F (week 16 before EE) were analysed. RESULTS:In total population, numerically higher improvements in most PROs were reported with abatacept (n?=?213) versus placebo (n?=?211) at both time points (P?>?0.05). Higher proportions of abatacept versus placebo patients reported PRO improvements ? MCID and???NV at week 16. At week 16, all PRO improvements were numerically greater (P?>?0.05) in patients with baseline CRP?>?ULN versus CRP???ULN (all significant [95% confidence interval] for abatacept vs placebo); improvements in SF-36 component summaries and FACIT-F were greater in TNFi-naïve versus TNFi-exposed patients (abatacept > placebo). Week 24 subgroup data were difficult to interpret due to low patient numbers. CONCLUSIONS:Abatacept treatment improved PROs in patients with PsA versus placebo, with better results in elevated baseline CRP and TNFi-naïve subpopulations.
