Percentage of Participants Meeting American College of Rheumatology Response Criteria ≥20% (ACR20): Month 3
ACR20 was calculated as a ≥20% improvement from baseline in tender/painful and swollen joint counts and ≥20% improvement from baseline in 3 of the 5 remaining ACR core set measures: patient's global assessment of arthritis, physician's global assessment of arthritis, patient's assessment of arthritis pain, health assessment questionnaire - disability index (HAQ-DI), and C-reactive protein (CRP).
Time frame: At end of Month 3
Change From Baseline in Health Assessment Questionnaire - Disability Index (HAQ-DI) Score
The HAQ-DI assesses the difficulty a participant has had in the past week in 8 domains of daily living activities: dressing and grooming, arising, eating, walking, hygiene, reach, grip, and other activities. Each activity category consists of 2-3 items. For each question, level of difficulty is scored from 0 to 3 with 0=no difficulty, 1=some difficulty, 2=much difficulty, and 3=unable to do. The score for each domain is the maximum (worst) score from the items/questions within the domain. Higher score indicates greater disability.
Time frame: From Baseline to Month 3
Change From Baseline in the Van Der Heijdel Modified Total Sharp Score (mTSS) for Psoriatic Arthritis
Assessment of joint damage includes a joint erosion score (range 0-320) and a joint space narrowing (JSN) score (range 0-208). The mTSS is the sum of the erosion and JSN scores (range 0-528). A higher score indicates more severe disease status. If a component score is missing, the mTSS will be missing.
Time frame: From Baseline to Month 12
Percentage of Participants With Progressed Modified Total Sharp Score (mTSS) at Month 12
Assessment of joint damage includes a joint erosion score (range 0-320) and a JSN score (range 0-208). The mTSS is the sum of the erosion and JSN scores (range 0-528). A higher score indicates more severe disease status. If a component score is missing, the mTSS will be missing. Progressor is defined as an increase in mTSS \>0.5 from baseline.

Change From Baseline in Physician's Global Assessment of Psoriasis (PGA-PsO) Response
The PGA-PsO is scored on a 5-point scale, reflecting a global consideration of the erythema, induration, and scaling across all psoriatic lesions. Average erythema, induration, and scaling are rated separately over the whole body according to a 5-point severity scale, scored as 0=none; 1, 2, 3, or 4=most severe. The severity rating scores are summed and the average taken; the total average is rounded to the nearest whole number score to determine a PGA-PsO score on a scale of 0 to 4 (0=clear, 1=almost clear, 2=mild, 3=moderate, 4=severe).
Time frame: From Baseline to Months 1, 3, 6, 9, and 12
Percentage of Participants With Psoriasis Area and Severity Index 75 (PASI75) Response at Months 1, 3, 6, 9, and 12
PASI determines psoriasis severity based on lesion severity \& percentage body surface area (BSA) affected. Lesion severity is assessed for erythema, induration, \& scaling, evaluated separately for head \& neck, upper limbs, trunk, \& lower limbs \& rated for each body area according to a 5 point scale: 0=no involvement; 1=slight; 2=moderate; 3=marked; 4=very marked. BSA involvement is the extent (%) of body area affected by psoriasis \& is assigned a score: 0=no involvement; 1=0-9%; 2=10-29%; 3=30-49%; 4=50-69%; 5=70-89%; 6=90-100%. In each area, sum of severity rating scores is multiplied by the score representing the percentage of area involved by psoriasis, multiplied by a weighting factor (head 0.1; upper limbs 0.2; trunk 0.3; lower limbs 0.4). The sum of numbers obtained for the 4 body areas is the PASI score \& can vary in increments of 0.1 \& range from 0.0 to 72.0, higher scores represent greater severity of psoriasis. PASI75 is defined as a 75% reduction from baseline in PASI.

Higher score indicates greater degree of tenderness.

Change From Baseline in the Short-Form-36 Health Survey Version 2 (SF-36v2) Acute, Physical Component Summary Score
The SF-36v2 acute is a 36-item measure that evaluates 8 domains: physical functioning, role physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health.

Change From Baseline in Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F) Scores: Total Score
FACIT-F is a 13-item questionnaire, with each item scored on a 5-point scale ranging from 0 (not at all) to 4 (very much). Three endpoints are derived: change in FACIT-F total score, change in FACIT-F experience domain score, and change in FACIT-F impact domain score.
