This research aims to evaluate the effectiveness of different doses of SAR442970 compared to placebo in adults with moderate to severe Ulcerative Colitis. It is a phase 2b, randomized, double-blind study conducted across multiple centers and countries. The study includes participants who have had active Ulcerative Colitis for at least three months and meet specific disease activity criteria measured by the modified Mayo Score. Participants will receive either SAR442970 or placebo through subcutaneous injections. The treatment period can last up to 158 weeks and includes a long-term open-label extension lasting up to 104 weeks for those who qualify. This design allows for assessment of both short-term and longer-term effects of the study drug. Throughout the study, researchers will monitor participants regularly to assess clinical remission using the modified Mayo Score at Week 16 as the primary outcome. Participants will undergo clinical evaluations, endoscopy, and other assessments to track disease activity and safety. The total study duration can extend up to 168 weeks, ensuring thorough long-term observation and safety monitoring.
