Primary Outcome Measures

Name	Time	Method
Percentage of Subjects With Physician's Global Assessment (PGA) Ratings of "Excellent" or "Cleared" at Week 24	Week 24	The PGA rating was used to assess the global response of all psoriatic lesions by comparing subject's present condition to baseline photographs or body diagrams. The response was classified as Cleared: 100% improvement of all clinical signs and symptoms compared to baseline; Excellent: 75% to 99% improvement of all signs and symptoms compared to baseline; Good: 50% to 74% improvement of signs and symptoms compared to baseline; Fair: 25% to 49% improvement of signs and symptoms compared to baseline; Slight: 1% to 24% improvement of signs and symptoms compared to baseline; Unchanged: Clinical signs and symptoms unchanged from baseline and Worse: Clinical signs and symptoms deteriorated from baseline.
