This clinical trial is focused on studying the effects of a treatment for ulcerative colitis, a condition that causes inflammation and sores in the colon and rectum. The treatment being tested is called guselkumab, which is a type of medication known as a monoclonal antibody. This medication is given as an injection under the skin using a pre-filled syringe. The study also includes a comparison with a placebo, which is a substance with no active medication.
The purpose of the study is to evaluate how effective and safe guselkumab is for people with moderately to severely active ulcerative colitis. Participants in the study will receive either the medication or a placebo. The study will last for a period of time, during which participants will receive regular injections and attend follow-up visits to monitor their health and the effects of the treatment.
Throughout the study, researchers will assess whether participants achieve clinical remission, which means a significant reduction or disappearance of symptoms. The study aims to provide valuable information about the potential benefits of guselkumab for individuals living with ulcerative colitis.
