          -  Candidate for phototherapy or systemic therapy

          -  Previous failure, inadequate response, intolerance, or contraindication to at least 1
             conventional anti-psoriatic systemic therapy

          -  Female participants should have negative serum pregnancy test during screening and a
             negative urine pregnancy test at baseline

          -  No known history of latent or active tuberculosis (TB), and has a negative test for TB
             during screening (with negative purified protein derivative (PPD), and Negative
             Quantiferon®/T-spot test)

          -  Participants with a positive purified protein derivative and a history of Bacillus
             Calmette-Guérin (BCG) vaccination are allowed with a negative Quantiferon®/T-spot®

          -  Participants with a positive PPD test (without history of BCG vaccination) or
             participants with a positive or indeterminate Quantiferon®/T-spot test are allowed if
             they have all of the following:

               -  No symptoms per TB worksheet provided by the sponsor

               -  Documented history of adequate prophylaxis initiation prior to receiving
                  investigational product (IP) in accordance with local recommendations

               -  No known exposure to a case of active TB after most recent prophylaxis

               -  No evidence of active TB on chest radiograph within 3 months prior to the first
                  dose of IP

        Exclusion Criteria:

        Participants are excluded from the study if any of the following criteria apply:

             guttate PsO, medication induced PsO, or other skin conditions at the time of the
             screening visit (eg, eczema) that would interfere with evaluations of the effect of IP
             on PsO

          -  Participant has an active infection, recurrent or chronic infections, serious
             infection or history of infections

          -  Known history of human immunodeficiency virus

          -  Hepatitis B surface antigen or hepatitis C virus antibody positivity at screening
