Percent of Subjects Who Achieve a Physician Global Assessment (PGA) Score of Clear (0) or Almost Clear (1) With a Minimum 2-grade Improvement From Baseline at Week 12. Analyses Were Done Using Multiple Imputation Primary · Baseline to Week 12

The PGA is a clinical tool for assessing the current state/severity of a subject's psoriasis at a given timepoint. A static 5-point scale is used to grade lesions on the clinical characteristics of erythema, scaling, and plaque thickness/elevation. The PGA ranges from 0 to 4, and is calculated as Clear (0), Almost clear (1), Mild (2), Moderate (3), and Severe (4). Higher PGA scores represent more severe disease. Analyses were done using multiple imputation.

Percent of Subjects With ≥ 75% Improvement in Psoriasis Area and Severity Index (PASI) From Baseline at Week 12. Analyses Were Done Using Multiple Imputation. Secondary · Baseline to Week 12

The Psoriasis Area and Severity Index (PASI) scoring system combines the assessment of lesion severity and extent of affected area into a single score: 0 (no disease) to 72 (maximal disease). The body is divided into 4 areas for scoring (head, arms, trunk, and legs). Each area is assessed for 3 signs: erythema (redness), induration (plaque thickness), and scale. The severity of each sign in each body area is assessed and scored independently using a 5-point scale, where 0=none, 1=slight, 2=mild, 3=moderate, 4=severe. Each area is also assessed for percent of skin involved: 0 = (0%), 1 = (1-\<1

Mean Change in Percent of Total Body Surface Area (%BSA) Affected From Baseline to Week 12 Secondary · Baseline to Week 12

Assessment of BSA with psoriasis was estimated by means of the handprint method, where the full palmar hand of the participant (fully extended palm, fingers and thumb together) represented approximately 1% of the total BSA. Body regions are assigned specific number of handprints with percentage \[Head and neck = 10% (10 handprints), upper extremities = 20% (20 handprints), Trunk (including axillae and groin) = 30% (30 handprints), lower extremities (including buttocks) = 40% (40 handprints)\]. Estimates of the % involvement in each body region will be multiplied by the fraction of total body a
