What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With Physician Global Assessment (PGA) of Psoriasis Score of 'Clear' or 'Almost Clear' at 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).

    Measured: Week 16

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

    Measured: Week 16

Secondary outcomes (51)
  1. Percent Change From Baseline in Total Body Surface Area (BSA) With Psoriasis at 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.

    Measured: Baseline, Week 16

  2. Percentage of Participants With a Psoriasis Area and Severity Index 90 (PASI 90) Response at Week 16

    The PASI quantifies the severity of a participant's psoriasis based on both, "lesion severity" and the "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 90 response was defined as at least a 90% reduction in PASI relative to Baseline.

    Measured: Week 16

  3. Dermatology Life Quality Index (DLQI) Total Score

    The DLQI is a 10-item general dermatology questionnaire that assess 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.

    Measured: Baseline

  4. Change From Baseline in Dermatology Life Quality Index (DLQI) Total Score at Week 4 and 16

    The DLQI is a 10-item general dermatology questionnaire that assess 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.

    Measured: Baseline, Week 4,16

  5. Percentage of Participants With Physician Global Assessment (PGA) of Psoriasis Score of 'Clear' or 'Almost Clear' at 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).

    Measured: Week 4

  6. Percentage of Participants With Psoriasis Area and Severity Index 75 (PASI 75) Response at Week 4

    The PASI quantifies the severity of a participant's psoriasis based on both, "lesion severity" and the "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 75 response was defined as at least a 75% reduction in PASI relative to Baseline.

    Measured: Week 4

  7. Percent Change From Baseline in Nail Psoriasis Severity Index (NAPSI) at 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.

    Measured: Baseline, Week 16

  8. Percent Probability of Participants Maintaining Physician Global Assessment (PGA) of Psoriasis Score of 'Clear' or 'Almost Clear' at 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).

    Measured: Week 52

  9. Percent Probability of Participants Maintaining Psoriasis Area and Severity Index 75 (PASI 75) Response at 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.
