Double-blind, Randomized, Placebo-controlled Phase 3 Study of Etanercept in the Treatment of Psoriatic Arthritis and Psoriasis

Summary

This was a phase 3, double-blind, placebo-controlled, randomized, multicenter study in subjects with psoriatic arthritis (PsA) and psoriasis comprising 3 periods: a 24-week double-blind period, a ≤ 24-week maintenance period, and a 48-week open-label period. During the double-blind period, subjects were randomized equally to 1 of 2 regimens: etanercept 25 mg twice weekly (BIW) or placebo, administered subcutaneously (SC). After the week 24 visit, subjects continued on blind-labeled therapy in a maintenance period until all subjects completed the double-blind period. After the maintenance period, all subjects received open-label etanercept 25 mg BIW.
