About

The purpose of this study is to demonstrate the superiority of CNTO 1959 (guselkumab) to placebo in the treatment of participants with moderate to severe plaque-type psoriasis (A common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches).

Full description

A Phase 3, multicenter (when more than one hospital or medical school team work on a medical research study), randomized (study drug assigned by chance), double-blind (neither the Investigator nor the participant know about the study treatment), placebo-controlled (a pretend treatment [with no drug in it] that is compared in a clinical trial with a drug to test if the drug has a real effect) study of CNTO 1959 (Guselkumab) in the treatment of participants with moderate to severe plaque-type psoriasis. Participants will receive either treatment of CNTO 1959 (guselkumab) 50 milligram (mg) or 100 mg or Placebo 50 mg or 100 mg. Participants will primarily be assessed for Investigator's Global Assessment (IGA) Score and Psoriasis Area and Severity Index (PASI). Participants' safety will be monitored throughout the study.
