A Phase 2a, Multicenter, Randomized, Double-blind Study Evaluating the Efficacy and Safety of Subcutaneously Administered Guselkumab and Golimumab Combination Therapy in Participants With Active Psoriatic Arthritis
The purpose of this study is to evaluate the efficacy of guselkumab plus golimumab combination treatment in participants with active psoriatic arthritis (PsA) and inadequate response (IR) to prior anti-tumor necrosis factor-alpha (anti-TNF-alpha) therapies by assessing clinical response compared with guselkumab monotherapy.
• Have a diagnosis of psoriatic arthritis (PsA) for greater than or equal to (\>=) 6 months prior to the first administration of study intervention and meet Classification criteria for PsA (CASPAR) criteria at screening
• Have active PsA as defined by having at least 3 swollen joints and at least 3 tender joints at screening and at baseline
• Have at least 1 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
• Have an inadequate response (IR) to anti-tumor necrosis factor-alpha (anti-TNF-alpha) therapy, defined as presence of active PsA despite treatment with either 1 or 2 prior anti-TNF-alpha agent(s) and the following: a. Lack of benefit to either 1 or 2 prior anti-TNF-alpha therapies, as documented in the participant history by the treating physician, after at least 12 weeks of etanercept, adalimumab, or certolizumab pegol therapy, or at least 14-weeks of infliximab, or any biosimilar of these 4 therapies. Documented lack of benefit may include inadequate improvement in joint counts, physical function, or disease activity; b. The last dose of anti-TNF-alpha therapy must have occurred greater than 5 half-lives of the drug prior to first study intervention administration (washout period)
