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.
|Eligible Ages||18 Years and Over|
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.

|Fistulizing Crohns Disease, Perianal Crohns Disease|
Crohn's disease is a chronic, progressive, and potentially life-threatening disorder which may affect any part of the gastrointestinal tract. Guselkumab is a fully human immunoglobulin G1 (IgG1) lambda monoclonal antibody (mAb) that binds to the p19 subunit of human interleukin (IL)-23 with high specificity and affinity, without blocking IL-12. The aim is to evaluate the efficacy and safety of guselkumab in the treatment of adult participants with active fistulizing, perianal Crohn's disease who have had an inadequate response with, lost response to, or were intolerant to either conventional therapy or biologic therapy or have medical contraindications to such therapies. This study consists of 3 phases: 6 weeks screening phase, 48 weeks treatment phase, and a 16 weeks follow-up phase. The study will have long term extension (LTE) period for participants who complete the 48-week treatment period and in the opinion of the investigator, will continue to benefit from the study intervention. Comprehensive safety data will be collected and the total duration of the study for participants will be up to 118 weeks (including the LTE period).
Experimental: Group 1: Guselkumab
Participants will receive guselkumab Dose 1 intravenous (IV) infusion followed by Dose 2 subcutaneously (SC). Participants will receive matching placebo to maintain the blind. Participants who are eligible and willing to continue guselkumab may enter the Long-Term Extension (LTE) period and continue to receive guselkumab.
Experimental: Group 2: Guselkumab
Participants will receive guselkumab Dose 1 IV infusion followed by Dose 3 SC. Participants will receive matching placebo to maintain the blind. Participants who are eligible and willing to continue guselkumab may enter the LTE period and continue to receive guselkumab.
Experimental: Group 3: Placebo
Participants will receive placebo IV infusion followed by placebo SC. At Week 24, placebo non-responders will continue to receive guselkumab Dose 4 followed by guselkumab Dose 2 SC. Participants will receive matching placebo to maintain the blind. Participants who are eligible and willing to continue guselkumab may enter the LTE period and continue to receive guselkumab.
Drug: - Guselkumab
Guselkumab will be administered subcutaneously/IV infusion.
