Phase 3 Study to Assess Safety and Effectiveness of Tulisokibart for Moderate to Severe Crohns Disease

What this Trial Is About

Researchers are evaluating the efficacy and safety of tulisokibart in participants with moderately to severely active Crohns disease. This program includes two studies Study 1 involves both induction and maintenance treatment phases, while Study 2 focuses only on induction treatment. The main goal is to determine if one or more doses of tulisokibart are more effective than placebo in achieving clinical remission and endoscopic response at various time points up to Week 52. Participants are randomly assigned to receive different dosing regimens of tulisokibart or placebo. These regimens include high or low doses administered intravenously followed by subcutaneous injections, or subcutaneous injections alone. Some participants may continue in an extension phase receiving subcutaneous doses after completing their original treatment arm if they meet specific requirements. The studies use a double-blind design to compare tulisokibarts effects against placebo. During the trial, participants undergo regular assessments to measure clinical remission, endoscopic response, and other health outcomes using tools like the Crohns Disease Activity Index and stool frequency with abdominal pain scores. Safety evaluations include monitoring adverse events and treatment discontinuations. The studies last up to 52 weeks for Study 1 and 12 weeks for Study 2, with multiple visits to assess treatment effects and participant health under medical supervision.
