Abstract
Objective To assess patient-reported outcomes (PRO) in patients with moderate-to-severe plaque psoriasis receiving continuous or paused etanercept treatment. Methods In a multicentre European open-label study, one group (n = 352) received continuous therapy: 25 mg subcutaneously (SC) twice weekly (BIW) throughout 54-weeks. The other group (n = 359) received paused therapy: 50 mg SC BIW (</= 12 weeks) until response was adequate by Physician Global Assessment; after psoriasis returned, retreatment (25 mg BIW) was begun. PRO included the Dermatology Life Quality Index (DLQI), EuroQoL-5D (EQ-5D), Hospital Anxiety and Depression Scale (HADS), and the SF-36 Vitality subscale. Results At baseline, mean DLQI for patients in the continuous (12.8) and paused group (13.8), indicated significant quality-of-life impairment; mean EQ-5D utility scores were 0.65 and 0.66 for continuous and paused patients, respectively; 30.0% of continuous and 37.0% of paused patients had at least mild symptoms of depression; 40.2% and 48.6%, respectively, had at least mild symptoms of anxiety. At week 54, both groups showed statistically significant (P < 0.05) and meaningful improvement in DLQI and EQ-5D scores; improvements in HADS-D, HADS-A, and SF-36 vitality were also significant. Improvements in DLQI and EQ-5D were significantly greater in the continuous arm than the paused arm, but the differences were not meaningful. Differences between arms in HADS and SF-36 Vitality at week 54 were not significant. Conclusions At baseline, patients exhibited significant quality-of-life impairment. Both continuous and paused etanercept treatment provided improvements in PRO measures. Either regimen could be considered and care should be individualized. Conflicts of interest None declared.
