  2. Have a diagnosis of PsA for at least 6 months prior to the first administration of study intervention and meet ClASsification criteria for Psoriatic ARthritis (CASPAR) criteria at screening
  3. Have active PsA as defined by having at least three swollen joints and three tender joints at screening and at baseline and CRP = 0.3 mg/dL at screening from the central laboratory
  4. Have = 2 joints with erosions on baseline radiographs of the hands and feet as determined by central read
  5. Have at least one of the following PsA subsets: distal interphalangeal joint involvement, polyarticular arthritis with absence of rheumatoid nodules, asymmetric peripheral arthritis, or spondylitis with peripheral arthritis
  6. Have active plaque psoriasis, with at least one psoriatic plaque of = 2cm diameter and/or nail changes consistent with psoriasis
  7. If currently using non-biologic Disease-modifying antirheumatic drugs (DMARDs), participants should have started treatment at least 3 months and the dose must be stable for at least 4 weeks before first administration of study intervention and should have no serious toxic side effects attributable to the non-biologic DMARD
  8. If currently not using MTX, SSZ, or HCQ, must not have received for at least 4 weeks before first administration of study intervention. If currently not using LEF, must not have received for at least 12 weeks before first administration of study intervention

  17. Agree not to receive a live virus or live bacterial vaccination during the study, or within 12 weeks after the last administration of study intervention
  18. Agree not to receive a bacillus Calmette-Guérin (BCG) vaccination during the study, and within 12 weeks after the last administration of study intervention
  19. Agree to avoid prolonged sun exposure and agree not to use of tanning booths or other ultraviolet (UV) light sources during study
  20. Be willing and able to adhere to the prohibitions and restrictions specified in this protocol
