Clinical Trial Outcome Measures

Primary Measures

  • Percentage of Participants Who Achieve a PASI75 Response at Week 16 Compared With Baseline (Week 0)
    • Time Frame: Week 0 and Week 16
    • PASI75 is defined as at least a 75% reduction in PASI (Psoriasis Area and Severity Index) score compared with the Baseline PASI score. PASI scores range from 0.0 (best) to 72.0 (worst), with the highest score representing complete erythroderma of the severest degree. The percent decrease in score is calculated as (Week 0 PASI score minus Week 16 PASI score) divided by Week 0 PASI score. Positive percent decreases indicate improvement, with best improvement being 100%. The outcome measure is the percentage of participants who had at least a 75% PASI score decrease.

Secondary Measures

    • Time Frame: Week 0 and Week 16
    • PASI50 is defined as at least a 50% reduction in PASI (Psoriasis Area and Severity Index) score compared with the Baseline PASI score. PASI scores range from 0.0 (best) to 72.0 (worst), with the highest score representing complete erythroderma of the severest degree. The percent decrease in score is calculated as (Week 0 PASI score minus Week 16 PASI score) divided by Week 0 PASI score. Positive percent decreases indicate improvement, with best improvement 100%. The outcome measure is the percentage of participants who had at least a 50% PASI score decrease.

PASI scores range from 0.0 (best) to 72.0 (worst), with the highest score representing complete erythroderma of the severest degree. The percent decrease in score is calculated as (Week 0 PASI score minus Week 16 PASI score) divided by Week 0 PASI score. Positive percent decreases indicate improvement, with best improvement 100%. The outcome measure is the percentage of participants who had at least a 90% PASI score decrease.
