Having 100% improvement from baseline in PASI score. The outcome measure is summarized using the least squares mean percentage of subjects having PASI 100 response at Week 16, based on a logistic regression model adjusted for baseline body weight (<=100 kg,>100 kg) and baseline PASI score.

The PASI is the most widely used tool in clinical practice and clinical trials to assess psoriasis severity and extent. Assessment is done based on the condition of the disease at the time of evaluation, not in relation to the condition at a previous visit. The investigator assesses the severity of 3 psoriasis disease characteristics (redness, thickness, and scaliness) on each of the 4 body regions (head/neck, trunk, upper extremities, lower extremities) according to a severity scale. The investigator also assesses the extent of psoriasis within each of the 4 body regions. This gives a composite score ranging from 0 to 72, with higher values indicating a more severe/extensive condition.

Having a score of 0 (clear) in IGA. The outcome measure is summarized using the least squares mean percentage of subjects having an IGA score of 0 at Weeks 16 and 28, based on a logistic regression model adjusted for baseline body weight (<=100 kg,>100 kg) and baseline IGA score.

The IGA is an instrument used in clinical trials to rate the severity of psoriasis and is based on a 5-point scale ranging from 0 (clear) to 4 (severe).

FAS

Having a score of 0 (clear) or 1 (almost clear) in IGA. The outcome measure is summarized using the least squares mean percentage of subjects having an IGA score of 0 or 1 at Weeks 16 and 28, based on a logistic regression model adjusted for baseline body weight (<=100 kg,>100 kg) and baseline IGA score.

The IGA is an instrument used in clinical trials to rate the severity of psoriasis and is based on a 5-point scale ranging from 0 (clear) to 4 (severe).

The outcome measure is summarized using the least squares mean percentage of subjects having a DLQI score of 0 or 1 at Weeks 4, 8, 12, 16, 20, 24, and 28, based on a logistic regression model adjusted for baseline body weight (<=100 kg,>100 kg) and baseline DLQI score.

The DLQI is a validated questionnaire with content specific to those with dermatology conditions. It consists of 10 items addressing the participant's perception of the impact of their skin disease on different aspects of their quality of life over the last week such as dermatology-related symptoms and feelings, daily activities, leisure, work or school, personal relationships, and the treatment. Each item is scored on a 4-point Likert scale (0 = 'not at all/not relevant'; 1 = 'a little'; 2 = 'a lot'; 3 = 'very much'). The total score is the sum of the 10 items (0 to 30); a high score is indicative of a poor quality of life.

The SF-36v2 is a 36-item general health status assessment. Participants answer each question by selecting 1 of 3 to 6 categorical response options. The SF-36v2 yields scores for 8 health domains (physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health) and 2 psychometrically derived summary scores (a physical component summary and a mental component summary). The physical component summary score ranges from 5.1 to 79.7. Higher scores indicate better outcome.
