结局指标
主要结局
Percentage of Participants With a Physician's Global Assessment (PGA) Response of "Clear" or "Almost Clear" at Week 12
时间窗: Week 12
The PGA of psoriasis is scored on a 5-point scale, reflecting a global consideration of the erythema, induration, and scaling across all psoriatic lesions. Average erythema, induration, and scaling are scored separately over the whole body according to a 5-point severity scale (0 to 4). The severity scores are summed and averaged after which the total average is rounded to the nearest whole number score to determine the PGA score and category (0=clear; 1=almost clear; 2=mild; 3=moderate; and 4=severe). PGA response was defined as 0 (clear) or 1 (almost clear).
Percentage of Participants With a Psoriasis Area and Severity Index 75 (PASI75) Response at Week 12
时间窗: Week 12
The PASI quantifies the severity of a participant's psoriasis based on both lesion severity and the percent of body surface area (BSA) affected. PASI is a composite scoring by the investigator of degree of erythema, induration, and scaling (each scored separately) for each of 4 body regions (head and neck, upper limbs, trunk \[including axillae and groin\], and lower limbs \[including buttocks), with adjustment for the percent of BSA involved for each body region and for the proportion of the body region to the whole body. The PASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of psoriasis. PASI75 response was defined as at least a 75 percent (%) reduction in PASI relative to baseline/Day 1.
