- Primary Outcome Measures
Name Time Method Percentage of Participants With Physician's Global Assessment (PGA) Score of "Clear" or "Almost Clear" at Week 16 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).
Percentage of Participants Achieving at Least a 75% Reduction in PASI (PASI75) at Week 16 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. PASI75 response was defined as at least a 75% reduction in PASI relative to Baseline.
- Secondary Outcome Measures
Name Time Method Change From Baseline in DLQI Total Score at Week 4 Baseline to Week 4 The DLQI is a 10 item general dermatology questionnaire that assesses health-related quality of life (daily activities, personal relationships, symptoms and feelings, leisure, work and school, and treatment). The DLQI item response options are rated by the participant from 0 (not at all/not relevant) to 3 (very much) with a total score range of 0 (best) to 30 (worst); higher scores indicate poor quality of life.
Percent Change From Baseline in Nail Psorasis Severity Index (NAPSI) at Week 16 in Participants With Nail Psoriasis at Baseline Baseline to 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 represent more severe psoriasis.
Percentage of Participants Maintaining PASI90 Response at Week 52 Among Participants Achieving PASI90 at Week 16 Week 16 to 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. PASI90 response=at least 90% reduction in PASI relative to Baseline. Maintenance of PASI90 response at Week 52 among patients achieving PASI90 response at Week 16 is reported. This is a key secondary endpoint. Probability and the 95% CI were estimated based on the Kaplan-Meier method. Event is loss of response. Percentage of maintaining response is (1-probability of loss of response).
Percentage of Participants With PGA Score of "Clear" or "Almost Clear" at Week 4 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).
Time to PASI50 Response up to Week 16 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). Median time to event is not estimable if the estimated probability of response by Week 16 is less than 50%.
Percent Change From Baseline in Total Body Surface Area (BSA) With Psoriasis at Week 16 Baseline to 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.
Percentage of Participants Achieving at Least a 90% Reduction in PASI (PASI90) at Week 16 Week 16 The PASI quantifies the severity of a participant's psoriasis based on both lesion severity and the percent of BSA affected.
