Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Physician Global Assessment (PGA) of Psoriasis Score of 'Clear' or 'Almost Clear' at Week 16
Time Frame: Week 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).
Week 16
Percentage of Participants With a Psoriasis Area and Severity Index 75 (PASI 75) Response at Week 16
Time Frame: Week 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.
Week 16

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percent Change From Baseline in Total Body Surface Area (BSA) With Psoriasis at Week 16
Time Frame: Baseline, 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. 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.
Baseline, Week 16
Percentage of Participants With Physician Global Assessment (PGA) of Psoriasis Score of 'Clear' or 'Almost Clear' at Week 4
Time Frame: Week 4
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).
Week 4
Percent Change From Baseline in Nail Psoriasis Severity Index (NAPSI) at Week 16
Time Frame: Baseline, Week 16
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.
Baseline, Week 16
Percent Probability of Participants Maintaining Physician Global Assessment (PGA) of Psoriasis Score of 'Clear' or 'Almost Clear' at Week 52
Time Frame: Week 52
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). Maintenance of PGA response at Week 52 among participants achieving PGA response at Week 16 is reported. Percent probability and 95% confidence interval (CI) were estimated based on the product limit estimator in survival analyses. Event is loss of response. Probability of maintaining response is (1-probability of loss of response).
Week 52
Percent Probability of Participants Maintaining Psoriasis Area and Severity Index 75 (PASI 75) Response at Week 52
Time Frame: Week 52
The PASI quantifies severity of a participant's psoriasis based on both, lesion severity and percent of BSA affected. PASI is a composite scoring by 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 percent of BSA involved for each body region and for the proportion of the body region to the whole body. The PASI score range from 0.0 to 72.0, with higher scores representing greater severity of psoriasis. PASI 75 response = at least 75% reduction in PASI relative to Baseline. Maintenance of PASI 75 response at Week 52 among participants achieving PASI 75 response at Week 16 is reported. Percent probability and 95% CI were estimated based on the product limit estimator in survival analyses. Event is loss of response. Probability of maintaining response is (1-probability of loss of response).
Week 52
Percent Probability of Participants Maintaining Psoriasis Area and Severity Index 90 (PASI 90) Response at Week 52
Time Frame: Week 52
The PASI quantifies severity of a participant's psoriasis based on both, lesion severity and percent of BSA affected. PASI is a composite scoring by 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 percent of BSA involved for each body region and for the proportion of the body region to the whole body. The PASI score range from 0.0 to 72.0, with higher scores representing greater severity of psoriasis. PASI 90 response = at least 90% reduction in PASI relative to Baseline. Maintenance of PASI 90 response at Week 52 among participants achieving PASI 90 response at Week 16 is reported. Percent probability and 95% CI were estimated based on the product limit estimator in survival analyses. Event is loss of response. Probability of maintaining response is (1-probability of loss of response).
Week 52
Time to Achieve a Physician Global Assessment (PGA) of Psoriasis Score of 'Clear' or 'Almost Clear'
Time Frame: Baseline up to Week 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). Median time to achieve a PGA response up to week 16 is reported. The median time to event was estimated based on the probability of event-rate based on life table estimates (not the observed rate as in outcome measure 1). Median time to event is not estimable if the estimated probability of response by Week 16 is less than 50%.
Baseline up to Week 16
Time to Achieve Psoriasis Area and Severity Index 50 (PASI 50) Response
Time Frame: Baseline up to Week 16
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. The median time to event was estimated based on the probability of event-rate based on life table estimates (not the observed rate as in outcome measure 26).

Baseline, Week 16
Family Dermatology Life Quality Index (FDLQI) Score
Time Frame: Baseline, Week 16, 52
The FDLQI is a 10-item questionnaire that examine the impact of health-related quality of life issues associated with living with a person with a skin condition (example, emotional distress, personal relationships, reactions of other people, social life, caregiving) over the last month. 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. Here 'N' (number of participants analyzed) signifies participants evaluable for this measure.
