Study to Assess the Immunogenicity and Safety of Etanercept Produced Using a Modified Process in Patients With Plaque Psoriasis

This is a multicenter, open-label, single-arm phase 4 study in patients with plaque psoriasis who are etanercept-naïve and who are not receiving methotrexate therapy. The study will consist of a screening period of up to 30 days, a 24-week treatment period and a 30-day follow-up period for safety. Etanercept dosing will follow the recommended label dosing for patients with plaque psoriasis.
