Arm Groups
Arm | Description | Assigned Intervention |
---|---|---|
Experimental Induction Study 1: Guselkumab Dose 1 |
Participants will receive guselkumab dose 1 intravenously (IV) in Induction Study 1. Subsequent study treatment will be determined by the participant's clinical response status at Week 12. |
|
Experimental Induction Study 1: Guselkumab Dose 2 |
Participants will receive guselkumab dose 2 IV in Induction Study 1. Subsequent study treatment will be determined by the participant's clinical response status at Week 12. |
|
Placebo Comparator Induction Study 1: Placebo IV |
Participants will receive matching placebo IV in Induction Study 1. Subsequent study treatment will be determined by the participant's clinical response status at Week 12. Clinical nonresponders will be administered guselkumab IV. |
|
Experimental Induction Study 2: Guselkumab IV |
Participants will receive guselkumab IV in Induction Study 2. Subsequent study treatment will be determined by the participant's clinical response status at Week 12. |
|
Placebo Comparator Induction Study 2: Placebo IV |
Participants will receive matching placebo IV in Induction Study 2. Subsequent study treatment will be determined by the participant's clinical response status at Week 12. Clinical nonresponders will be administered guselkumab IV. |
|
Experimental Maintenance Study: Maintenance Dose Regimen 1 |
Participants will receive guselkumab maintenance dose regimen 1 subcutaneously (SC) every 4 weeks (q4w). |
|
Experimental Maintenance Study: Maintenance Dose Regimen 2 |
Participants will receive guselkumab maintenance dose regimen 2 SC every 8 weeks (q8w). |

Detailed Description
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.
