             prior to baseline as determined by the investigator.

          -  Have Psoriasis Area and Severity Index (PASI) score ≥12 and a Static Physician Global
             Assessment (sPGA) ≥3 and body surface area involvement ≥10% at screening and baseline.

          -  Are candidates for phototherapy or systemic treatment or considered by the
             investigator as not adequately controlled by topical therapies.
