The proportions of patients in whom ACR50\/ACR70 and skin responses, minimal or very low disease activity, and dactylitis or enthesitis resolution were achieved at week 24 were also maintained through week 52. Further, low levels of radiographic progression, along with improvements in physical function and health\u2010related quality of life, were sustained through week 52 with continued guselkumab treatment. Few patients experienced serious infections through week 52, with no evidence of a dosing regimen response or increase from weeks 0\u201324 (4 of 493 [0.8%]) to weeks 24\u201352 (3 of 493 [0.6%]) among guselkumab\u2010randomized patients.
