About

The purpose of this research study is to see how well the medication Alefacept (Amevive®) works for continuous treatment of chronic plaque psoriasis. The US Food and Drug Administration (FDA) has approved Alefacept in an intermittent dosage schedule of 15 mg weekly injection for 12 weeks followed by 12 weeks off treatment.

Full description

To estimate the efficacy of continuous use of alefacept (15mg IM/week) in the treatment of moderate to severe chronic plaque type psoriasis as defined as Investigator Global Assessment (IGA) of 0 or 1 (clear or almost clear) or as a 75% reduction in Psoriasis Area and Severity Index (PASI).
