Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants Achieving a Reduction (Improvement) in Psoriasis Area and Severity Index (PASI) Score of ≥ 75% From Baseline to Week 16

    The PASI score ranges from 0-72 (with a higher score indicating greater severity of psoriasis), based on a combination of the severity (erythema, induration, and desquamation) of psoriasis and percentage of affected area.

    Baseline (Day 1) to Week 16

Secondary Outcomes (8)

  • Percentage of Participants Achieving ≥ 2-point Reduction (Improvement) in Physician's Global Assessment (PGA) Score at Week 16

    Baseline (Day 1) to Week 16

  • Percentage of Participants Achieving a Clear (0) or Almost Clear (1) Score in PGA at Week 16

    Week 16

  • Percentage of Participants Achieving Reduction (Improvement) in PASI Score of ≥ 50% From Baseline to Week 16

    Baseline (Day 1) to Week 16

  • Percentage of Participants Achieving Reduction (Improvement) in PASI Score of ≥ 90% From Baseline to Week 16

    Baseline (Day 1) to Week 16

  • Number of Participants With Treatment-Emergent Adverse Events (TEAEs)

    First dose of study drug to the last dose of study drug (up to Week 12) plus approximately 30 days past last dose

  • +3 more secondary outcomes
