Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Physician Global Assessment (PGA) of Psoriasis Score of 'Clear' or 'Almost Clear' at Week 16Week 16

The PGA of psoriasis 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 scored separately over the whole body according to a 5-point severity scale (0 \[no symptom\] to 4 \[severe symptom\]). The total score was calculated as average of the 3 severity scores and rounded to the nearest whole number score to determine the PGA score and category (0=clear; 1=almost clear; 2=mild; 3=moderate; and 4=severe). PGA response was defined as 0 (clear) or 1 (almost clear).

Percentage of Participants With a Psoriasis Area and Severity Index 75 (PASI 75) Response at Week 16Week 16

The PASI quantifies the severity of a participant's psoriasis based on both, "lesion severity" and the "percent of body surface area (BSA)" affected. PASI is a composite scoring by the investigator of degree of erythema, induration, and scaling (each scored separately) for each of 4 body regions (head and neck, upper limbs, trunk \[including axillae and groin\], and lower limbs \[including buttocks\]), with adjustment for the percent of BSA involved for each body region and for the proportion of the body region to the whole body. The PASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of psoriasis. PASI 75 response was defined as at least a 75 percent (%) reduction in PASI relative to Baseline.

Secondary Outcome Measures
NameTimeMethod

HADS: 14-item questionnaire that screens for the presence of anxiety and depression symptoms. There are 7 items comprising the anxiety subscale, and 7 items comprising the depression subscale. Each item has response option ranging from 0 (no presence of anxiety or depression) to 3 (severe feeling of anxiety or depression). Total score ranges from 0 to 21 for each subscale; higher score indicates greater severity of anxiety or depression symptoms.

All the scales ranged from 0 (limited none of the time) to 100 (limited all of the time). The WLQ Index score is the weighted sum of the scores from the 4 WLQ scales (total score: 0 \[no loss\] to 100 \[complete loss of work\]).

The FDLQI need to be completed by a family member (for example, spouse or partner, parent) who currently lives with the participant. Each question is scored on a scale from 0 (Not at all/ Not relevant) to 3 (Very much). Total score is calculated by summing the score of each item resulting in a maximum score of '30' and a minimum score of '0'. Higher scores indicate greater impairment to quality of life.

Percent Change From Baseline in Total Body Surface Area (BSA) With Psoriasis at Week 16Baseline, Week 16

Assessment of BSA with psoriasis was estimated by means of the handprint method, where the full palmar hand of the participant (fully extended palm, fingers and thumb together) represented approximately 1% of the total BSA.

Each finger nail divided with imaginary lines into quadrants and scored for both nail matrix and nail bed psoriasis (range from 0 \[absence of psoriasis\] to 4 \[presence of psoriasis in all 4 quadrants\]). The total NAPSI score equals the sum of scores for all of the finger nails evaluated and ranges from 0 to 80. Higher scores = more severe psoriasis.

Assessment of BSA with psoriasis was estimated by means of the handprint method, where the full palmar hand of the participant (fully extended palm, fingers and thumb together) represented approximately 1% of the total BSA. Body regions are assigned specific number of handprints with percentage \[Head and neck = 10% (10 handprints), upper extremities = 20% (20 handprints), Trunk (including axillae and groin) = 30% (30 handprints), lower extremities (including buttocks) = 40% (40 handprints)\]. The number of handprints of psoriatic skin in a body region was used to determine the extent (%) to which a body region was involved with psoriasis. The total BSA affected was the summation of individual regions affected.

Percentage of Participants With Psoriasis Area and Severity Index 50 (PASI 50) ResponseWeek 2, 4, 8, 12, 16, 20, 28, 40, 52

The PASI quantifies the severity of a participant's psoriasis based on both, "lesion severity" and "percent of BSA" affected. PASI is a composite scoring by the investigator of degree of erythema, induration, and scaling (each scored separately) for each of 4 body regions (head and neck, upper limbs, trunk \[including axillae and groin\], and lower limbs \[including buttocks\]), with adjustment for the percent of BSA involved for each body region and for the proportion of the body region to the whole body. The PASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of psoriasis. PASI 50 response was defined as at least 50% reduction in PASI relative to Baseline. Percentage of participants with PASI 50 response is reported.

Percentage of Participants With Psoriasis Area and Severity Index 90 (PASI 90) ResponseWeek 2, 4, 8, 12, 16, 20, 28, 40, 52

The PASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of psoriasis. PASI 90 response was defined as at least 90% reduction in PASI relative to Baseline. Percentage of participants with PASI 90 response up to Week 52 is reported.

The PASI score can vary in increments of 0.1 and range from 0.0 to 72.0, with higher scores representing greater severity of psoriasis. Percentage of participants with PASI score of at least 125% of baseline PASI score are reported.

Nail Psoriasis Severity Index (NAPSI) ScoreBaseline, Week 8, 16, 20, 28, 40, 52

The NAPSI quantifies severity of nail psoriasis by evaluating the presence or absence of psoriatic manifestations on the nail matrix (pitting, leukonychia, red spots on lulunea, crumbling) and nail bed (onycholysis, splinter hemorrhages, subungual hyperkeratosis, oil drop \[salmon patch dyschromia\]). Each finger nail divided with imaginary lines into quadrants and scored for both nail matrix and nail bed psoriasis (range from 0 \[absence of psoriasis\] to 4 \[presence of psoriasis in all 4 quadrants\]). The total NAPSI score equals the sum of scores for all of the finger nails evaluated and ranges from 0 to 80. Higher scores = more severe psoriasis.

Each finger nail divided with imaginary lines into quadrants and scored for both nail matrix and nail bed psoriasis (range from 0 \[absence of psoriasis\] to 4 \[presence of psoriasis in all 4 quadrants\]). The total NAPSI score equals the sum of scores for all of the finger nails evaluated and ranges from 0 to 80. Higher scores = more severe psoriasis.

Number of Affected NailsBaseline, Week 8, 16, 20, 28, 40, 52

Nail psoriasis is evaluated by the presence or absence of psoriatic manifestations on the nail matrix (pitting, leukonychia, red spots on lulunea, crumbling) and nail bed (onycholysis, splinter hemorrhages, subungual hyperkeratosis, oil drop \[salmon patch dyschromia\]). Total number psoriasis affected nails (presence of psoriatic manifestations on the nail matrix/nail bed) were assessed and reported.

Baseline ISI is average of scores on 7 days prior to start of study treatment.
