Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Experimental: Group 1: Guselkumab and Placebo
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.
Experimental: Group 2: Guselkumab
Participants will receive guselkumab SC. Participants who have not discontinued will be eligible to enter an LTE and will receive guselkumab SC.
Experimental: Group 3: Placebo Followed by Guselkumab
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.
Drug: - Guselkumab
Participants will receive guselkumab as SC injection.
Drug: - Placebo
Participants will receive matching placebo as SC injection.
