ArmDescriptionAssigned Intervention
Experimental
Guselkumab (Every 8 weeks) 		Participants treated with guselkumab in one of the three primary studies (CNTO1959PUC3001 [NCT06260163], CNTO1959PBCRD3007 [NCT05923073], CNTO1275JPA3001 [NCT05083182]) will be enrolled in this long-term extension (LTE) study, if in investigator's opinion, participant will benefit from continued guselkumab therapy and will have continued access to guselkumab (every 8 weeks [q8w]). Participants coming from double-blinded arm of primary studies CNTO1959PUC3001 and CNTO1959PBCRD3007 will be assigned to q8w dosing. Based on investigator's discretion and participant's clinical status, they have option to switch to q4w once during LTE study prior to unblinding of primary study assignment. Once the primary study is unblinded, dosing frequency may be adjusted to match what the participant had received before enrolling in LTE study. Participants coming from study CNTO1275JPA3001 will continue same dosing regimen from primary study (q8w) and cannot change their dosing interval during LTE study.
  • Drug: Guselkumab
    Guselkumab will be administered as subcutaneous injection.

Experimental
Guselkumab (Every 4 weeks) 		Participants treated with guselkumab in one of the three primary studies (CNTO1959PUC3001 [NCT06260163], CNTO1959PBCRD3007 [NCT05923073], CNTO1275JPA3001 [NCT05083182]) will be enrolled in this LTE study, if in the investigator's opinion, the participant will benefit from continued guselkumab therapy. Participants will have continued access to guselkumab (q4w). Participants coming from the open-label arm of the primary studies CNTO1959PUC3001 and CNTO1959PBCRD3007 will be assigned to q4w dosing. No dose adjustments are permitted. Participants coming from the jPsA primary study (CNTO1275JPA3001) will continue the same dosing regimen from the primary study (q4w) and cannot change their dosing interval during the LTE study.
