Description of intervention(s) / exposure
Treatment: Drugs - Guselkumab
Treatment: Drugs - Placebo

Experimental: Group 1: Guselkumab - Participants will receive subcutaneous (SC) guselkumab 100 milligram (mg) once every 4 weeks (q4w) from Week 0 through Week 48.

Experimental: Group 2: Guselkumab and Placebo - Participants will receive SC guselkumab 100 mg at Weeks 0 and 4, then once every 8 weeks (q8w) (Weeks 12, 20, 28, 36, and 44) and placebo injections at other visits (Weeks 8, 16, 24, 32, 40, 48) to maintain the blind.

Experimental: Group 3: Placebo Followed by Guselkumab - Participants will receive SC placebo q4w from Week 0 to Week 20, and will crossover at Week 24 to receive guselkumab 100 mg q4w from Week 24 through Week 48.


Treatment: Drugs: Guselkumab
Participants will receive 100mg of guselkumab as a sterile liquid for SC injection.

Treatment: Drugs: Placebo
Participants will receive matching placebo as SC injection.
