Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With a =75% Improvement in Psoriasis Area and Severity Index (PASI 75) at Week 24	The PASI combines the extent of body surface involvement in 4 anatomical regions (head, trunk, arms, and legs). For each region the percent area of skin involved was estimated from 0 (0%) to 6 (90%-100%) and severity was estimated by clinical signs of erythema, induration and scaling with a scores range from 0 (no involvement) to 4 (severe involvement). Each area is scored separately and the scores then combined for the final PASI. Final PASI calculated as: sum of severity parameters for each region * area score * weighing factor [head (0.1), upper limbs (0.2), trunk (0.3), lower limbs (0.4)]. Overall scores range from 0 (no Ps) to 72 (the most severe disease).	Week 24
Secondary	Percentage of Participants With a =90% Improvement in Psoriasis Area and Severity Index (PASI 90) From Baseline	The PASI combines the extent of body surface involvement in 4 anatomical regions (head, trunk, arms, and legs).

Each area is scored separately and the scores then combined for the final PASI. Final PASI calculated as: sum of severity parameters for each region * area score * weighing factor [head (0.1), upper limbs (0.2), trunk (0.3), lower limbs (0.4)].

Each area is scored separately and the scores then combined for the final PASI. Final PASI calculated as: sum of severity parameters for each region * area score * weighing factor [head (0.1), upper limbs (0.2), trunk (0.3), lower limbs (0.4)].

For each region the percent area of skin involved was estimated from 0 (0%) to 6 (90%-100%) and severity was estimated by clinical signs of erythema, induration and scaling with a scores range from 0 (no involvement) to 4 (severe involvement). Each area is scored separately and the scores then combined for the final PASI. Final PASI calculated as: sum of severity parameters for each region * area score * weighing factor [head (0.1), upper limbs (0.2), trunk (0.3), lower limbs (0.4)]. Overall scores range from 0 (no Ps) to 72 (the most severe disease).

Secondary	Percentage of Participants With a Static Physician Global Assessment (sPGA) (0,1) and =2 Point Improvement From Baseline Among Those With sPGA Score =3 at Baseline	The sPGA is the physician's determination of the participant's Psoriasis (Ps) lesions overall at a given time point. Lesions were categorized by descriptions for induration, erythema, and scaling. Participants Ps were assessed as 0 (clear), 1 (minimal), 2 (mild), 3 (moderate), 4 (severe), or 5 (very severe). An sPGA responder was defined as having a post-baseline sPGA score of "0" or "1" with at least a 2-point improvement from baseline.	Week 24
Secondary	Percentage of Participants Achieving DLQI (0,1)	The DLQI is a simple, participant-administered, 10 question, validated, quality-of-life questionnaire that covers 6 domains: symptoms and feelings, daily activities, leisure, work and school, personal relationships, and treatment. Response categories include "not at all," "a lot," and "very much," with corresponding scores of 1, 2, and 3, respectively, and unanswered ("not relevant") responses scored as "0."

The weighted sum of each PBQ item with its respective PNQ importance yields the PBI score.; LS mean was calculated using ANCOVA with LOCF and with a term for treatment.	Week 24
Secondary	Change From Baseline on Itch Numeric Rating Scale (NRS) Score	The Itch NRS is a participant-administered single-item 11-point horizontal scale anchored at 0 and 10, with 0 representing "no itch" and 10 representing "worst itch imaginable."

Secondary	Percentage of Participants With Positive Responses to Neck/Face Psoriasis Question	Studying psoriasis involvement in the face, neck, and the genitals is of considerable interest for participants. These are locations that bear high potential for stigmatization and/or psychological distress, and, hence, effects in those regions are assumed to heavily influence participant's quality of life.; Following set of binary questions were asked to check the satisfaction of participants.; Does the participant currently have visible psoriasis on face/neck? (Yes/No); Does the participant currently have psoriasis on the genital area? (Yes/No)	Week 24
Secondary	Percentage of Participants Positive Responses to Genital Psoriasis Question	Studying psoriasis involvement in the face, neck, and the genitals is of considerable interest for participants.
