Secukinumab improves patient-reported outcomes in subjects with active psoriatic arthritis: results from a randomised phase III trial (FUTURE 1)

Objective To evaluate the effect of secukinumab on patient-reported outcomes (PROs) in subjects with active psoriatic arthritis (PsA) in the FUTURE 1 study. Methods Subjects were randomised 1:1:1 to receive intravenous (i.v.) secukinumab 10 mg/kg at weeks 0, 2 and 4 followed by subcutaneous secukinumab 150 or 75 mg every 4 weeks or matching placebo until week 24. Results At week 24, subjects receiving secukinumab i.v. -> 1 50 mg or i.v. -> 75 mg reported greater least squares mean changes from baseline than those receiving placebo in patient global assessment of disease activity (-20.6 and -20.0 vs -7.4, respectively), patient assessment of pain (-20.8 and -20.4 vs -6.7), psoriatic arthritis quality of life (-3.5 and -3.2 vs -0.4), Dermatology Life Quality Index (-8.8 and -7.9 vs 0.7); p<0.0001 vs placebo for both secukinumab groups for above PROs and Functional Assessment of Chronic Illness Therapy-Fatigue (6.74 (p<0.05 vs placebo) and 6.03 vs 4.00); all of which well exceeded minimum clinically important differences. Conclusions In subjects with PsA, secukinumab treatment resulted in clinically meaningful improvements in global disease activity, pain, generic and disease-specific measures of health-related quality of life and fatigue.
