The purpose of this study is to evaluate the efficacy and safety of guselkumab in participants with moderately to severely active ulcerative colitis (UC).


UC is a chronic disease of the large intestine, in which the lining of the colon becomes inflamed and develops ulcers. Guselkumab is a fully human immunoglobulin G1 lambda monoclonal antibody (mAb) that binds to human interleukin (IL)-23 with high affinity. The study is designed to answer scientific questions pertaining to the efficacy and safety of guselkumab in the treatment of moderately to severely active UC. Overall, the study will evaluate long-term guselkumab treatment. Efficacy, safety, pharmacokinetics (PK), immunogenicity, and biomarkers will be assessed at specified time points.
