 (submitted: November 1, 2018)
  • Percentage of Participants With Physician's Global Assessment (PGA) 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).
  • Percentage of Participants Achieving at Least a 75% Reduction in PASI (PASI75) 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. PASI75 response was defined as at least a 75% reduction in PASI relative to Baseline.

Current Secondary Outcome Measures  ICMJE
 (submitted: April 4, 2019)
  • Percent Change From Baseline in Total Body Surface Area (BSA) With Psoriasis at Week 16 [ Time Frame: 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 [ Time Frame: Week 16 ]
    The PASI quantifies the severity of a participant's psoriasis based on both lesion severity and the percent of BSA affected.

The total NAPSI score equals the sum of scores for all of the finger nails evaluated and ranges from 0 to 80. Higher scores represents more severe psoriasis. NAPSI 100 response was defined as at least a 100% reduction in NAPSI relative to Baseline. Percentage of participants with NAPSI 100 response is reported.
  • Actual Itch Severity Item (ISI) Score Over Time Through Week 52 [ Time Frame: Baseline and Weeks 2, 4, 8, 12, 16, 20, 32, 40, and 52 ]
    ISI assessed severity of itch (pruritus) due to psoriasis. ISI is a single item, horizontal numeric rating scale. Participants were asked to rate "your worst itching due to psoriasis over the past 24 hours" on a numeric rating scale anchored by the terms "No itching" (0) and "Worst possible itching" (10) at the ends for post baseline time points. Baseline ISI is average of scores on 7 days prior to start of study treatment.
