The Psoriasis Area and Severity Index (PASI) is a composite score based on the degree of effect on body surface area of psoriasis and the extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The severity of each sign was assessed using a 5-point scale, where 0=no symptoms, 1=slight, 2=moderate, 3=marked, 4=very marked. The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis. PASI90 is defined as at least a 90% reduction in PASI score compared with the Baseline PASI score. The percent reduction in score is calculated as (PASI score at Baseline - score at follow-up visit) / PASI score at Baseline * 100. Non-responder imputation (NRI) was used for missing data.

Intent to Treat (ITT) analysis set: all participants who were randomized.

The PSS asks the participant to rate the severity of symptoms of psoriasis in the last 24 hours (pain, redness, itching, and burning) using a 5-point Likert -type scale ranging from 0 (none) to 4 (very severe). The PSS is calculated by summing the scores of the questions and ranges from 0 to 16, where the higher the score, the greater the severity of psoriasis symptoms. LOCF imputation was used for missing data.

The PBI is a patient-reported outcome instrument that assesses the benefit of psoriasis treatment.The PBI assessment consists of 2 steps: before treatment, every participant defines his/her treatment needs according to a standardized list (Patient Needs Questionnaire [PNQ]). After treatment, the participant rates the degree of benefits achieved (Patient Benefits Questionnaire [PBQ]). 25 items are rated on a 5-point scale with values from 0 (not at all) to 4 (very), allowing for "did not apply to me" (5) and missing. For each treatment goal the PNQ importance is derived by dividing the respective PNQ item by the sum of all PNQ items. The weighted sum of each PBQ item with its respective PNQ importance yields the PBI score. An increase in PBI indicates improvement. LOCF imputation was used for missing data.

The NAPPA-CLIN is an investigator assessment used to assess the severity of nail matrix psoriasis (leukonychia, red spots, dots, nail plate crumbling) and psoriasis of the nail bed (oil drop, splinter haemorrhage, subungual hyperkeratosis, onycholysis). NAPPA-CLIN has been developed from the Nail Psoriasis Severity Index (NAPSI) score, a nail psoriasis-specific score, which in its original version comprises the assessment of matrix and nail bed involvement in every finger and toe by 2 criteria for each nail. The NAPPA-CLIN is a simplified version of the NAPSI which only assesses the least and the worst involved nail of both hands or both feet respectively. Thus, the NAPPA-CLIN scores for hands or feet range from 0 to 16. A higher score indicates a worse involvement. LOCF imputation was used for missing data.

The PPASI is an assessment by the investigator that provides a numeric scoring for psoriasis affecting the hands and feet with scores ranging from 0 to 72. It is a linear combination of percent of surface area of palms and soles that are affected and the severity of erythema, induration, and desquamation. The higher the score, the greater the severity of psoriasis symptoms. LOCF imputation was used for missing data.

BSA affected by psoriasis was measured by the physician selecting the participant's right or left hand as the measuring device. For purposes of clinical estimation, the total surface of the palm plus 5 digits was to be assumed to be approximately equivalent to 1% BSA. Measurement of the total area of involvement by the physician was aided by imagining if scattered plaques were moved so that they were next to each other and then estimated the total area involved. A decrease in BSA affected by psoriasis indicates improvement. LOCF imputation was used for missing data.

The DLQI is a 10-question questionnaire that asks the participant to evaluate the degree that psoriasis has affected their quality of life in the last week and includes 6 domains (symptoms and feelings, daily activities, leisure, work and school, personal relationships, and treatment). Responses to each domain are not relevant (0), not at all (0), a little (1), a lot (2), and very much (3). The DLQI is calculated by summing the scores of the questions and ranges from 1 to 30, where 0-1 = no effect on patient's life, 2-5 = small effect, 6-10 = moderate effect, 11-20 = very large effect, and 21-30 = extremely large effect on patient's life. The higher the score, the more the quality of life is impaired. A 5-point change from baseline is considered a clinically important difference. NRI was used for missing data.

The physician assessed the severity of scalp psoriasis using the PSSI, which consists of an assessment of erythema, induration, and desquamation on a scale from 0 (none) to 4 (very severe) and the percentage of scalp involved on a scale from 0 (0% of scalp involved) to 6 (90-100% of scalp involved). The composite score is calculated as the sum of symptom scores multiplied by the score for the area of scalp involved. The PSSI ranges from 0 (best) to 72 (worst). A negative change from Baseline indicates improvement. LOCF imputation was used for missing data.

The EQ-5D-5L is a standardized non-disease specific instrument for describing and valuing health-related quality of life. The EQ-5D-5L descriptive system comprises 5 dimensions of health (mobility, self -care, usual activities, pain/discomfort, and anxiety/depression) to describe the subject's current health state. Each dimension comprises 5 levels with corresponding numeric scores, where 1 indicates no problems, and 5 indicates extreme problems. A unique EQ-5D-5L health state is defined by combining the numeric level scores for each of the 5 dimensions and the total score is normalized from -0.594 to 1.000, with higher scores representing a better health state. An increase in the EQ-5D-5L total score indicates improvement. LOCF imputation was used for missing data.

The EQ-5D-5L is a standardized non-disease specific instrument for describing and valuing health-related quality of life. The EQ-5D-5L VAS records the participant's self-rated health on a vertical visual analogue scale numbered from 100 (best health imagined) to 0 (worst health imagined). The VAS score from the scale is then entered as a number by the participant. This can be used as a quantitative measure of health outcome that reflects the participant's own judgement. An increase in the EQ-5D-5L VAS score indicates improvement. LOCF imputation was used for missing data.

The NAPSI score is calculated by summing the scores of all the nails which for each nail are the sum of the nail matrix score and nail bed score. Each of these is scored as 0=none, 1=present in 1/4 nail, 2=present in 2/4 nail, 3=present in 3/4 nail, 4=present in 4/4 nail. Each nail has a matrix score (0-4) and a nail bed score (0-4). The total nail score is the sum of those 2 (nail matrix and nail bed) individual scores (0-8). The sum of the total score of all involved fingernails is then the total NAPSI score. The NAPSI score is calculated only if all questions in the case report form are completed. A negative change from Baseline indicates improvement. LOCF imputation was used for missing data.
