Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percent Improvement From Baseline in Psoriasis Area and Severity Index (PASI) at Week 16	The PASI measures the average redness (erythema), thickness (induration), and scaliness (each graded on a 0 to 4 scale) of psoriasis lesions, weighted by the area of involvement in the four main body areas (i.e., head and neck, trunk, upper extremities, and lower extremities). PASI scores can range from 0.0 to 72.0, with higher scores indicating greater severity and/or more extensive psoriasis.; Percent improvement from baseline was calculated as (value at baseline - value at post-baseline visit) × 100 / (value at baseline).	Baseline and Week 16
Secondary	Percent Improvement From Baseline in PASI at Week 4?8?12?24?32?48?50	The PASI measures the average redness (erythema), thickness (induration), and scaliness (each graded on a 0 to 4 scale) of psoriasis lesions, weighted by the area of involvement in the four main body areas (i.e., head and neck, trunk, upper extremities, and lower extremities). PASI scores can range from 0.0 to 72.0, with higher scores indicating greater severity and/or more extensive psoriasis.; Percent improvement from baseline is calculated as (value at baseline - value at post-baseline visit) × 100 / (value at baseline).	Baseline and week 4?8?12?24?32?48?50
Secondary	Percentage of Participants With a PASI 75 Response at Week 4?8?12?16?24?32?48?50	A PASI 75 response is a 75% or greater improvement (reduction) from baseline in PASI score. The PASI measures the average redness (erythema), thickness (induration), and scaliness (each graded on a 0 to 4 scale) of psoriasis lesions, weighted by the area of involvement in the four main body areas (i.e., head and neck, trunk, upper extremities, and lower extremities). PASI scores can range from 0.0 to 72.0, with higher scores indicating greater severity and/or more extensive psoriasis.	Baseline and Week 4?8?12?16?24?32?48?50

A sPGA response is defined as a sPGA value of clear (score 0) or almost clear (score 1).	Week 4?8?12?16?24?32?48?50
Secondary	Change From Baseline in the Percentage of Body Surface Area (BSA) Involved With Psoriasis at Week 4?8?12?16?24?32?48?50	A measurement of psoriasis involvement, given as the physician's assessment of the percentage of the participant's total body surface area (BSA) involved with psoriasis. The percent of BSA affected was estimated by assuming that the subject's palm, excluding the fingers and thumb, represented roughly 1% of the body's surface.; Change from baseline is calculated as (value at post-baseline visit - value at baseline).; A decrease from baseline (negative value) indicates improvement.
