Phase 2 Study to Test the Safety and Effectiveness of SAR441566 Tablets in Adults Aged 18 to 75 With Moderate-to-Severe Ulcerative Colitis

What this Trial Is About

Researchers are evaluating the efficacy and safety of SAR441566 in adults with moderate-to-severe ulcerative colitis, a chronic inflammatory bowel condition. This Phase 2, multinational, randomized, double-blind, placebo-controlled study aims to assess how different doses of SAR441566 affect clinical remission in participants. The study includes participants aged 18 to 75 years who have active moderate-to-severe ulcerative colitis confirmed by endoscopy and who have previously received treatment for the condition. Participants will be randomly assigned to receive one of three different dose regimens of SAR441566 or a matching placebo. The medication is administered orally as tablets. The study includes a screening period of up to 28 days, followed by a main treatment period lasting 52 weeks. This treatment period is divided into a 12-week induction phase and a 40-week maintenance phase, followed by a 2-week follow-up after treatment ends. Additionally, eligible participants may enter an open-label extension period lasting up to 40 weeks. During the study, participants will attend up to 12 visits in the main treatment phase and up to 8 visits during the open-label period. Researchers will assess clinical remission using the modified Mayo Score at Week 12, along with various secondary measures such as endoscopic remission, patient-reported outcomes, and safety evaluations. Blood samples will be taken to measure drug concentrations, and adverse events will be monitored throughout the study. The total participation duration can be up to 59 weeks, including screening, treatment, and follow-up.
