Primary Outcome Measures

Name	Time	Method
Maintenance of PASI 90 Response at Week 52 in Participants With a PASI 90 Response at Week 24	Week 52	PASI is a combined assessment of lesion severity and affected area into a single score: 0 (no disease) to 72(maximal disease). Body is divided into 4 areas for scoring (head, arms, trunk, legs; each area is scored by itself and scores are combined for final PASI. For each area, percent of skin involved is estimated: 0 (0%) to 6 (90-100%), and severity is estimated by clinical signs, erythema, induration and desquamation; scale 0 (none) to 4 (maximum). Final PASI = sum of severity parameters for each area\* area score weight of section (head: 0.1, arms: 0.2 body: 0.3 legs: 0.4).

Body is divided into 4 areas for scoring (head, arms, trunk, legs; each area is scored by itself and scores are combined for final PASI. For each area, percent of skin involved is estimated: 0 (0%) to 6 (90-100%), and severity is estimated by clinical signs, erythema, induration and desquamation; scale 0 (none) to 4 (maximum).

PASI 50, PASI 75, PASI 100 and IGA Mod 2011 0 or 1 Responders at Week 52 in Participants With a PASI 90 Response at Week 24	week 52	PASI is a combined assessment of lesion severity and affected area into a single score: 0 (no disease) to 72 (maximal disease). Body is divided into 4 areas for scoring (head, arms, trunk, legs; each area is scored by itself and scores are combined for final PASI. For each area, percent of skin involved is estimated: 0 (0%) to 6 (90-100%), and severity is estimated by clinical signs, erythema, induration and desquamation; scale 0 (none) to 4 (maximum).

PASI 50, 75, 90 and 100 were defined as participants achieving ≥ 50%, 75%, 90% or 100% improvement from baseline. The IGA mod 2011 scale is static, i.e. it referred exclusively to the participant's disease at the time of the assessment, and did not compare with any of the participant's previous disease states at previous visits. The scores are: 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate and 4 = severe.
Change From Baseline in PASI in Participants With a PASI 90 Response at Week 24	Baseline, Weeks 28, 32, 36, 40, 44, 48 and 52	PASI is a combined assessment of lesion severity and affected area into a single score: 0 (no disease) to 72(maximal disease). Body is divided into 4 areas for scoring (head, arms, trunk, legs; each area is scored by itself and scores are combined for final PASI. For each area, percent of skin involved is estimated: 0 (0%) to 6 (90-100%), and severity is estimated by clinical signs, erythema, induration and desquamation; scale 0 (none) to 4 (maximum). Final PASI = sum of severity parameters for each area\* area score weight of section (head: 0.1, arms: 0.2 body: 0.3 legs: 0.4). A negative change from baseline indicates improvement.
Change From Baseline in DLQI in Participants With a PASI 90 Response at Week 24	Baseline, Week 52	The DLQI is a ten item general dermatology disability index designed to assess health-related quality of life in adult participants with skin diseases such as eczema, psoriasis, acne and viral worts. It is a self-administered questionnaire which includes domains of daily activity, leisure, personal relationships, symptoms and feelings, treatment and school/work activities. Each domain has 4 response categories ranging from 0 (not at all) to 3 (very much). "Not relevant" is a valid score also and is scored as 0. The DLQI total score is a sum of all 10 responses. Scores range from 0 to 30 with higher scores indicating greater health-related quality of life impairment. A negative mean percentage change from baseline indicates improvement.
Change From Baseline in Pain, Itching and Scaling Score in Participants With a PASI 90 Response at Week 24	Baseline, Week 52	Self-administered, 11-point numeric rating scales (NRS, 0-10) were used to evaluate the patients' assessment of their current pain, itching and scaling. Respondents answered the following questions for the assessment: Pain: Overall, how severe was your psoriasis-related pain over the past 24 hours?; Itching: Overall, how severe was your psoriasis-related itch over the past 24 hours?; and Scaling: Overall, how severe was your psoriasis-related scaling over the past 24 hours? Patients had to rate their pain, itching, and scaling from 0 to 10 (11-point scale), with the understanding that the 0 represents the absence or null end of the pain, itching, or scale intensity (i.e. no pain, itching or scaling) and the 10 represents the other extreme of pain, itching, or scaling intensity (i.e. pain, itching or scaling as bad as it could be). The number that the patient selected represents his or her intensity score in the respective category. A negative change from baseline indicates improvement

Change From Baseline in Work Productivity and Activity Impairment Questionnaire - Psoriasis (WPAI-PSO) Score in Participants With a PASI 90 Response at Week 24	Baseline, Week 52	The WPAI-PSO is a self-administered questionnaire comprised of 6 questions about effects of psoriasis on the patient's ability to work and perform regular activities based on the previous 7 days. The questionnaire quantifies the number of hours the respondent was unable to work and evaluates how much the respondent's psoriasis affected productivity while working. For respondents who were not in paid employment, the questionnaire evaluated how much the respondent's psoriasis affects their ability to perform regular daily activities. Four outcomes were generated from the WPAI-PSO: % Absenteeism: percent work time missed due to health; % Presenteism: percent impairment while working due to health; % Total work productivity impairment: percent overall work impairment due to health; % Total activity impairment: percent activity impairment due to health for all respondents. First 3 outcomes applied to employed participants only. A negative change from baseline indicates improvement.

Change From Baseline in the European Quality of Life - 5 Dimensions (EQ-5D) Visual Analogue Scale (VAS) in Participants With a PASI 90 Response at Week 24	Baseline, Week 52	A visual analogue scale (VAS) was used within the EQ-5D. This scale recorded the respondent's self-rated health on a vertical 20-cm VAS where the endpoints were labeled "best imaginable health state" and "worst imaginable health state." This resulted in a numeric value set ranging from 0 (="worst imaginable health state") up to 100 (="best imaginable health state"). A positive change from baseline indicates improvement.

Change From Baseline in the EQ-5D Utility Index (Germany, United Kingdom (UK)) in Participants With a PASI 90 Response at Week 24	Baseline, Week 52	The EQ-5D quantifies the health state of a patient for the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort \& anxiety/depression. In this study the EQ-5D-5L version has been used which evaluates each of these dimensions using the following 5 labels: no problems, slight problems, moderate problems, severe problems \& unable to/extreme problems. Based on the 5 dimensions, a summary score (utility index) was derived using country specific value sets evaluating the patient condition described by the outcome in the single dimensions. The EQ-5D-5L (in this trail) utility index based on the crosswalk value sets available from the EuroQol for Germany \& UK (https://euroqol.org/eq-5d-instruments/eq-5d-5l-about/) was calculated. A positive change from baseline indicates improvement. A visual analogue scale was used within the EQ-5D measuring the health state of the patients, ranging from 0 (worst imaginable health state) up to 100 (best imaginable health state).
