Study Comparing 2 Different Strategies For Management of Subjects With Plaque Psoriasis Who Have Responded to Etanercept

This study proposes to compare 2 different methods for managing a subject with psoriasis who has achieved good disease control, as defined by a clinical response with a Physician Global Assessment (PGA) inferior or equal to 1 at the screening visit, on etanercept treatment.

The first method involves stopping etanercept treatment on entry into the study, with the option to reinitiate etanercept at 50 mg once weekly after medical review and agreement between the subject and the investigator. The second method involves continuing on etanercept at 25 mg once weekly, with the option to increase the dose to 50 mg once weekly after medical review and agreement between the subject and the investigator. Subjects will be randomized into one of these two study arms.
