Study of the Drug Efalizumab (Raptiva), for Adult Patients With Moderate to Severe Plaque Psoriasis

Completed · Phase 3

Conditions studied: Psoriasis

In brief

Our laboratory is studying a skin disease known as psoriasis. The purpose of this protocol is to study the action and the effects of Efalizumab, on psoriasis. This medication has been studied extensively and has been found to be effective and safe in the treatment of psoriasis. The eligible patient will have 10% of his/her body surface area involved with psoriasis vulgaris.
