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.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

The disease, disorder, syndrome, illness, or injury that is being studied.
Crohn's disease is a chronic, progressive and potentially life-threatening disorder which may affect any part of the gastrointestinal (GI) tract. Guselkumab is a fully human immunoglobulin G1 lambda monoclonal antibody that binds to human interleukin (IL)-23, thereby blocking the binding of extracellular IL-23 to the cell surface IL-23 receptor. This binding results in inhibition of IL-23 mediated intracellular signaling, activation and cytokine production. The purpose of the study is to evaluate the efficacy and safety of guselkumab in participants with moderately to severely active Crohn's disease. The overall study duration is up to 109 weeks.
Experimental: Group 1: Guselkumab
Participants will receive guselkumab (Dose 1) injection subcutaneously followed by guselkumab (Dose 2) injection subcutaneously.
Experimental: Group 2: Guselkumab
Participants will receive guselkumab (Dose 1) injection subcutaneously followed by guselkumab (Dose 3) injection subcutaneously.
Placebo Comparator: Group 3: Placebo
Participants will receive placebo injection subcutaneously.
Drug: - Guselkumab Dose 1
Guselkumab (Dose 1) will be administered by subcutaneous (SC) injection.
Drug: - Guselkumab Dose 2
Guselkumab (Dose 2) will be administered by SC injection.
Drug: - Guselkumab Dose 3
Guselkumab (Dose 3) will be administered by SC injection.
Drug: - Placebo
Placebo will be administered by SC injection.
