Phase 3 Study of Icotrokinra for Induction and Maintenance Treatment in Adults and Adolescents with Moderate to Severe Ulcerative Colitis

What this Trial Is About

Researchers are evaluating oral icotrokinra as a treatment for adults and adolescents with moderately to severely active ulcerative colitis, a chronic inflammatory disease of the large intestine causing ulcers in the colon lining. The study aims to assess how well icotrokinra works, along with its safety and tolerability in this population. This is a Phase 3, randomized, double-blind, placebo-controlled trial with a parallel group design including both adults and adolescents. Adult participants will be randomly assigned to receive either icotrokinra or placebo daily by mouth during a 12-week induction phase. At Week 12, those showing clinical response will enter a maintenance phase where they will continue icotrokinra or placebo daily for 40 weeks. Adults who do not respond will also enter the maintenance phase and receive icotrokinra. Adolescents will receive open-label icotrokinra during induction and then continue on icotrokinra during maintenance regardless of response. After completing the 40-week maintenance phase, eligible participants may join a long-term extension study. Participants will be monitored regularly through clinical assessments at specified time points including Week 12 for induction and Week 40 for maintenance. Outcomes measured include rates of clinical remission, symptom improvement, endoscopic and histologic healing, and quality of life scores. Safety will be evaluated by tracking adverse and serious adverse events throughout the study. The total study duration may extend up to approximately 6 years, ending in 2032, allowing long-term evaluation of icotrokinra in ulcerative colitis management.
