Researchers are evaluating the safety and effectiveness of SAR441566 in adults with moderate to severe Crohn's Disease in this phase 2, multinational, randomized, double-blind, placebo-controlled study. The main goal is to compare different doses of SAR441566 against a placebo to see how well they work in treating Crohn's Disease. The study involves participants who have had a confirmed diagnosis of Crohn's Disease for at least three months and have shown moderate to severe symptoms. Participants will take either SAR441566 tablets or matching placebo tablets orally during the study. The study begins with a 4-week screening period, followed by a 52-week main treatment phase that includes 12 weeks of induction treatment and 40 weeks of maintenance treatment under double-blind conditions. After this, a 2-week follow-up is conducted for those not entering the long-term safety study. Eligible participants may join an open-label phase lasting up to 40 weeks, but the combined time in maintenance and open-label phases will not exceed 40 weeks. During the study, participants will undergo assessments including endoscopy to measure response at week 12. Researchers will monitor symptoms, stool frequency, and abdominal pain scores to evaluate treatment effects. Safety will be tracked throughout the study, including a follow-up after treatment ends. The total study duration for participants can be up to 59 weeks, with careful monitoring to ensure accurate evaluation of SAR441566's impact on Crohn's Disease.
