Eligibility Criteria
Inclusion Criteria
- •Have active psoriatic arthritis (PsA) despite previous non-biologic disease-modifying antirheumatic drug (DMARD), apremilast, and/or nonsteroidal anti-inflammatory drug (NSAID) therapy
- •Have a diagnosis of PsA for at least 6 months before the first administration of study agent and meet Classification criteria for Psoriatic Arthritis (CASPAR) at screening
- •Have active PsA as defined by: at least 3 swollen joints and 3 tender joints at screening and at baseline; and C-reactive protein (CRP) greater than or equal to (\>=) 0.3 milligrams per deciliter (mg/dL) at screening from the central laboratory
- •Have \>= 2 joints with erosions on baseline radiographs of the hands and feet as determined by central read
- •Have at least one of the following PsA subsets: distal interphalangeal joint involvement, polyarticular arthritis with absence of rheumatoid nodules, arthritis mutilans, asymmetric peripheral arthritis, or spondylitis with peripheral arthritis
- •Have active plaque psoriasis, with at least one psoriatic plaque of \>= 2 centimeter (cm) diameter or nail changes consistent with psoriasis
Exclusion Criteria
- •Has known allergies, hypersensitivity, or intolerance to study intervention or its excipients
- •Has other inflammatory diseases that might confound the evaluations of benefit of guselkumab therapy, including but not limited to rheumatoid arthritis (RA), axial spondyloarthritis (AS)/non-radiographic axial spondyloarthritis (nr-axSpA), systemic lupus erythematosus, or Lyme disease
- •Has previously received any biologic treatment
- •Has ever received tofacitinib, baricitinib, filgotinib, peficitinib, decernotinib, upadacitinib or any other Janus kinase (JAK) inhibitor
- •Has received any systemic immunosuppressants (example, azathioprine, cyclosporine, 6 thioguanine, mercaptopurine, mycophenolate mofetil, hydroxyurea, tacrolimus) within 4 weeks of the first administration of study intervention
Arms & Interventions
Group 2: Guselkumab
Participants will receive guselkumab SC. Participants who have not discontinued will be eligible to enter an LTE and will receive guselkumab SC.
Intervention: Guselkumab
Group 1: Guselkumab and Placebo
Participants will receive guselkumab and placebo subcutaneously (SC) to maintain the blind. Participants who have not discontinued will be eligible to enter a long-term extension (LTE) and will receive guselkumab and placebo SC. After the study is unblinded to the investigative sites, participants will receive guselkumab and no longer be required to dose with placebo to maintain the blind.
Intervention: Placebo
Group 3: Placebo Followed by Guselkumab
Participants will receive placebo SC and will cross over to receive SC guselkumab. Participants who have not discontinued will be eligible to enter an LTE and will receive guselkumab SC.
Intervention: Placebo
Group 1: Guselkumab and Placebo

Outcomes
Primary Outcomes
Percentage of Participants Who Achieved an American College of Rheumatology (ACR) 20 Response at Week 24
Time Frame: At Week 24
ACR 20 response: \>=20% improvement from baseline (bl) in both swollen (66 joints), tender (68 joints) joint count, \>=20% improvement from bl in 3 of 5 assessments: patient's assessment of pain using visual analog scale (VAS; 0-100mm, 0=no pain, 100=worst possible pain), patient's global assessment of disease activity (arthritis, VAS; 0-100mm, 0=excellent, 100=poor), physician's global assessment of disease activity (VAS; 0-100mm, 0=no arthritis activity,100=extremely active arthritis), HAQ-DI (questionnaire assessing 8 functional areas; 0-3, 0=no difficulty, 3=inability to perform task in area), and CRP. Natural Disaster (ND)-site inaccessible due to COVID-19. Major Disruption (MD)-disruption involving Ukraine and neighboring countries/territories. Intercurrent event (ICE) handling: Composite-discontinue study drug not due to ND/MD, initiate/increase DMARD/oral corticosteroid, initiate prohibited PsA treatment; Hypothetical-discontinue/severe noncompliance of study drug due to ND/MD.
