Psoriasis Area Severity Index (PASI)75 Success at Visit 6 Primary · Week 12 (Visit 6)

PASI75 success at Visit 6 was defined as number of participants who achieved at least 75% reduction in PASI scores at Visit 6 compared to Visit 2 (Baseline). The PASI score was determined through evaluation of body surface area (BSA) covered by plaque psoriasis in four regions (head/neck, upper extremities, trunk and lower extremities). This assessment included a combination of both degree of involvement (assessed as per the % of affected body area using a 7-point scale that ranged as 0 (0% involvement), 1 = 1-9%, 2 = 10-29%, 3 = 30-49%, 4 = 50-69%, 5 = 70-89% and 6 = 90-100%) and severity (ev

Investigator's Global Assessment (IGA) at Each Post Baseline Visit Secondary · Week 1 to Week 20 (Visit 3 to Visit 8)

The IGA was used to assess the overall severity of a participant's plaque psoriasis at a particular time point and the evaluation took into consideration the three individual characteristics of plaque psoriasis (scaling, plaque elevation, and erythema). The IGA was recorded using a scale that ranged from 0 (clear), 1 = almost clear, 2 = mild, 3 = moderate to 4 (severe) in whole-unit increments; higher scores indicating worse psoriasis. Investigators did not refer to previous evaluations when conducting the IGA assessment. At every study visit, the investigator evaluated each participant's plaq

PASI75 at Each Post Baseline Visit Except Visit 6 Secondary · Week 1 to Week 20 (Visit 3 to Visit 8) except Week 12 (Visit 6)

PASI75 success was defined as number of participants who achieved at least 75% reduction in PASI scores at each post baseline visit (Visit 3 to Visit 8) except Visit 6. The PASI score was determined through evaluation of BSA covered by plaque psoriasis in four regions (head/neck, upper extremities, trunk and lower extremities).
