Primary Outcome Measures :
  1. Percentage of Participants With Psoriasis Area Severity Index (PASI) 75 at Week 12 [ Time Frame: 12 weeks ]
    The Psoriasis Area and Severity Index Score is used as a scale to show change from Baseline of study to a certain point. PASI Score ranges from (0) no disease to (72) maximal disease. The proportion of subjects achieving 75% improvement in Psoriasis Area and Severity Index, PASI75, was assessed.

  2. Percentage of Participants With Static Physician Global Assessment (sPGA) Success Score (Score of 0 or 1) at Week 12 - Comparison to Placebo [ Time Frame: 12 weeks ]
    Static Physician Global Assessment (sPGA) measures the physician's impression of the disease. Possible scores are (0 [clear] to 5 [severe]). Success was defined by a score of 0 or 1 (clear to almost clear).
