Phase 2b Study to Evaluate the Safety and Effectiveness of Obefazimod Compared to Placebo in Adults With Moderately to Severely Active Crohns Disease

What this Trial Is About

Researchers are studying obefazimod to evaluate its effectiveness and safety as a treatment for adults with moderately to severely active Crohns disease who have not responded well or cannot tolerate conventional or advanced therapies. This Phase 2b trial compares obefazimod with a placebo to see if it can help control symptoms and improve disease activity. The study also aims to assess the long-term safety and tolerability of obefazimod during an extension period. The study includes three treatment phases a 12-week induction phase, a 40-week maintenance phase, and a 48-week extension phase. Participants receive one of four daily treatments obefazimod at doses of 50mg, 25mg, or 12.5mg, or a placebo. All treatments are taken once daily, ideally in the morning with food. The extension phase focuses on monitoring safety and tolerability compared to placebo. Participants will attend regular study visits for assessments including the Crohns Disease Activity Index and endoscopic scores to measure disease activity and response. Safety is monitored through adverse event reports and laboratory tests, including blood work for hematology, coagulation, and biochemistry at various weeks up to the end of the study. The total study duration spans several phases, allowing close observation of treatment effects and safety over time.
