- Psoriasis Area and Severity Index (PASI) (Efficacy) [ Time Frame: 98 days. ]
- Area of Involvement. Determine a score, from 0 to 6, for each body section (head, trunk, upper limbs, lower limbs) based on the percent of psoriasis skin involvement: 0=0%, 1=<10%, 2=10% to <30%, 3=30% to <50%, 4=50% to <70%, 5=70% to <90%, 6=90% to 100%.
- Severity of Involvement. Determine a score, from 0 to 4, for each body section (head, trunk, upper limbs, lower limbs), for the psoriatic skin severity of each of erythema, thickness, and scaling: 0=none, 1=slight, 2=moderate, 3=severe, 4=very severe. For each body section the three severity scores are summed.
- For each body section the product of the Area and Severity is determined.
- For each body section the product of line 3 is multiplied by an Area Factor (head=0.1, trunk=0.3, upper limbs=0.2, lower limbs=0.4).
- A PASI score is determined by summing the 4 body section products (line 4). The highest possible score=72; the lowest possible score=0. The higher the scores, the worse the psoriasis.
- Static Physician Global Assessment (sPGA) (Efficacy) [ Time Frame: 98 days. ]
- Induration. A score, from 0 to 5, based on: 0=No plaque elevation; 1= Minimal plaque elevation=0.25 mm; 2=Mild plaque elevation=0.5 mm; 3=Moderate plaque elevation=0.75 mm; 4=Marked plaque elevation=1.0 mm; 5=Severe plaque elevation>1.25 mm.
- Erythema. A score, from 0 to 5, based on: 0=No erythema, hyperpigmentation may be present; 1=Faint erythema; 2=Light red coloration; 3=Moderate red coloration; 4=Bright red coloration; 5=Dusky to deep red coloration.
- Scaling. A score, from 0 to 5, based on: 0= No scaling; 1=Minimal; occasional fine scale on<5% of the lesion; 2=Mild; fine scale predominates; 3=Moderate; coarse scale predominates; 4=Marked; thick, non-tenacious scale predominates; 5=Severe; very thick, tenacious scale predominates.
- The sPGA: Induration, Erythema, and Scaling scores are rounded to the nearest whole number and averaged. 0=Cleared; 1=Minimal; 2=Mild; 3=Moderate; 4=Marked; 5=Severe. Higher score indicates worse psoriasis.
- Analysis of Treatment Emergent Adverse Events [ Time Frame: 140 days. ]Analysis of treatment emergent adverse events to include incidence, severity, and relationship to study drug treatment.
