Outcome Measures
Primary Outcomes (1)
Percentage of Participants With Physician Global Assessment (PGA) Score of Cleared (0) or Minimal (1) at Week 16
PGA of psoriasis is used to determine the participant's psoriasis lesions overall at a given time point. Lesions were graded as erythema \[0 (no evidence of plaque) to 5 (dusky to deep red coloration)\], induration \[0 (no plaque evaluation) to 5 (marked plaque evaluation)\] and scaling \[0 (no evidence of scaling) to 5 (severe; very thick tenacious scaling)\]. 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= cleared; 1= minimal; 2= mild; 3= moderate; 4= marked and 5= severe).
Week 16
Secondary Outcomes (4)
Percentage of Participants Who Achieved Psoriasis Area and Severity Index (PASI) 75 Response at Week 16
Week 16
Difference in Percentage of Participants With Physician Global Assessment (PGA) Score of Cleared (0) or Minimal (1) in CNTO1959 Groups Compared With Adalimumab Group at Week 16
Week 16
Percentage of Participants With Physician Global Assessment (PGA) Score of Cleared (0) or Minimal (1) at Week 40
Week 40
Change From Baseline in Dermatology Life Quality Index (DLQI) Score at Week 16
