950 participants in 3 patient groups

Group 1: Guselkumab and Placebo
Experimental group
Description:
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.
Treatment:
Drug: Guselkumab
Drug: Placebo
Group 2: Guselkumab
Experimental group
Description:
Participants will receive guselkumab SC. Participants who have not discontinued will be eligible to enter an LTE and will receive guselkumab SC.
Treatment:
Drug: Guselkumab
Group 3: Placebo Followed by Guselkumab
Experimental group
Description:
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.
Treatment:
Drug: Guselkumab
Drug: Placebo
