Percentage of Participants Who Achieved a Psoriasis Area and Severity Index (PASI) 50 Response Over Time

PASI is a composite score based on the degree of effect on body surface area of psoriasis and the extension of erythema (reddening), induration (plaque thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The PASI score ranges from 0 (no psoriasis) to 72 (very severe psoriasis). A PASI 50 response is defined as at least a 50% reduction (improvement) from baseline in PASI score.

Percentage of Participants Achieving a Physician's Global Assessment of Disease Activity (PGA) of Cleared or Minimal Over Time

The PGA is a 6-point scale used to measure the severity of disease at the time of the evaluation. The degree of overall lesion severity was evaluated using the following categories: * 0 (Cleared): No evidence of scaling, erythema, or plaque elevation; * 1 (Minimal): Occasional fine scale over \<5% of lesions, faint erythema, minimal plaque elevation; * 2 (Mild): Fine scale dominates, light red coloration, mild plaque elevation; * 3 (Moderate): Course scale dominates, moderate red coloration, moderate plaque elevation; * 4 (Marked): Thick non-tenacious scale dominates, bright red coloration, marked plaque elevation; * 5 (Severe): Very thick tenacious scale predominates, dusky to deep red coloration, severe plaque elevation. The percentage of participants achieving a score of clear (0) or minimal (1) is reported.

Time frame: Weeks 8, 16, and 24

Change From Baseline in Body Surface Area (BSA) Affected by Psoriasis

The total body surface area affected by psoriasis (expressed as a percentage) was measured by the investigator using the palm method, where the participant's hand represents 1% of body surface area. A decrease in BSA affected by psoriasis indicates improvement.

Change From Baseline in Dermatology Life Quality Index (DLQI) Score Over Time

The DLQI questionnaire asks participants to evaluate the degree that psoriasis has affected their quality of life in the last week, and includes the following parameters: symptoms and feelings, daily activities, leisure activities, work or school activities, personal relationships and treatment related feelings. Participants answer 10 questions on a scale from 0 (not at all) to 3 (very much); the range of the total score is 0 to 30. A score of 21 to 30 means an extremely large effect on the participant's life whereas 0-1 means that the disease has no effect at all. A negative change from Baseline indicates improvement.
