A Study to Assess the Efficacy and Safety of Golimumab in Pediatric Participants With Moderately to Severely Active Ulcerative Colitis

The purpose of this study is to evaluate efficacy of golimumab in inducing clinical remission as assessed by the Mayo score, in pediatric participants with moderately to severely active ulcerative colitis (UC). In addition, the safety profile of golimumab, in pediatric participants with moderately to severely active UC will be assessed.
