Eligibility

Primary outcome measure(s)

• Percentage of Participants Who Achieved an Investigator's Global Assessment (IGA) Score of 0 or 1 and a Greater Than or Equal to (>=) 2-Grade Improvement From Baseline at Week 16 — Week 16
  IGA assesses participant's plaque psoriasis. Lesions were graded for induration, erythema, scaling, each using 5 point scale. Induration:0=no evidence of plaque elevation, 1=minimal plaque elevation,=0.25 millimeters(mm); 2=mild plaque elevation,=0.5 mm; 3=moderate plaque elevation,=0.75 mm; 4=severe plaque elevation,\>1 mm; Erythema: 0=no evidence of erythema, hyperpigmentation may be present, 1=faint erythema, 2=light red coloration, 3=moderate red coloration, 4=bright red coloration; Scaling: 0=no evidence of scaling, 1=minimal; occasional fine scale over less than 5% of lesion, 2=mild; fine scale dominates, 3=moderate; coarse scale predominates, 4=severe; thick, scale predominates. Final IGA score was based upon average of induration, erythema and scaling scores assessed on 5 point scale: cleared (0), minimal (1), mild (2), moderate (3), or severe(4). Higher score=more severe disease. Baseline=closest measurement taken prior to or at time of first study drug administration date.
• Percentage of Participants Who Achieved Psoriasis Area and Severity Index (PASI) 90 at Week 16 — Week 16
  Percentage of participants who achieved PASI-90 score (\>=90% improvement from baseline in PASI) at Week 16 was reported. The PASI was a system used for assessing and grading the severity of psoriatic lesions and their response to therapy. In the PASI system, the body was divided into 4 regions: the head, trunk, upper extremities, and lower extremities. Each of these areas was assessed and scored separately for erythema, induration, and scaling, which were each rated on a scale of 0 to 4 (0 = none, 1 = slight, 2 = moderate, 3 = severe and 4 = very severe) and extent of involvement from 0 (indicated no involvement) to 6 (90% - 100% involvement). The PASI produced a numeric total score that could range from 0 (no psoriasis) to 72 (maximum psoriasis). Higher score indicated greater severity of psoriasis. The baseline was defined as the closest measurement taken prior to or at the time of the first study drug administration date.
