Name	Time	Method
Number of Subjects With Psoriasis Area and Severity Index (PASI) 75 Response at 16 Weeks	16 weeks	PASI 75 is a 75% or greater improvement on the Psoriasis Area and Severity Index (PASI). The PASI scale runs from 0-72, where 0 = no psoriasis and 72 = complete erythroderma of the severest possible degree
