Title: An Exploratory Phase 2a, Randomized, Double-blind, Placebo-controlled, Multicenter Study To Assess Mechanism Of Action (Moa) Of Cp-690,550 In The Skin When Administered Orally At 10 Mg Twice Daily (Bid) For 12 Weeks In Subjects With Moderate To Severe Chronic Plaque Psoriasis
Brief Summary: There are cells in the skin and blood of humans with chronic moderate to severe plaque psoriasis with specific activities that may determine the effectiveness of treatment. These activities may be described by obtaining samples of skin and blood and analyzing them using a variety of tests.
