Inclusion Criteria
  • Diagnosis of juvenile psoriatic arthritis (jPsA) by Vancouver criteria with exclusion of enthesitis-related arthritis (ERA). Diagnosis made >=3 months (that is, 90 days) prior to screening

  • Concurrent use of methotrexate, sulfasalazine, leflunomide, oral corticosteroids or NSAIDs is permitted but must be on stable dose
  • Participants must be up to date with all immunizations in agreement with current local immunization guidelines for immunosuppressed patients

GroupInterventionDescription
Cohort 1: UstekinumabUstekinumabParticipants will receive a weight-based dose of ustekinumab subcutaneously (SC) at Week 0, Week 4 and then every 12 weeks up to Week 52. Cohort 1 is closed for further enrollment.
Cohort 2: GuselkumabGuselkumabThe dose of guselkumab will be based on the participant's weight. Participants will receive guselkumab SC at Weeks 0 and 4 followed by either every 4 weeks (Q4W) (with historical radiographic evidence of joint damage) or every 8 weeks (Q8W) (without historical evidence of joint damage) dosing with the last dose at Week 52. Participants at high risk of joint damage can also be considered for Q4W dosing per investigator.
