Information on the long-term efficacy of etanercept (ETN) treatment of moderate-to-severe psoriasis according to the Summary of Product Characteristics (SmPC) is scarce.
We report the efficacy results of an observational clinical trial including 202 patients treated for 12 months with ETN according to SmPC.
Concomitant topical treatment was permitted throughout the study period. Efficacy assessment was done by intention-to-treat analysis with last observation carried forward.
Mean%Body Surface Area (BSA) and Psoriasis Area and Severity Index (PASI) decreased from 39.0% and 22.2% at baseline to 7.9% and 4.4%, respectively, at 12 months. Throughout the study duration, PASI 50, PASI 75 and PASI 90 response rates ranged from 72.8% to 95.7%, 55.6% to 84.3%, and 36.1% to 62.2%, respectively. Body mass index and body weight had minor effects on treatment efficacy.
ETN treatment according to the SmPC provided sustained improvement of psoriasis throughout one year.
