This study looks at how well a new medicine, SAR442970, works for adults with Ulcerative Colitis (UC). UC is a disease that causes swelling and sores in the large intestine. This study lasts up to 3 years, with some people getting the medicine for about 2 years. It's a "double-blind" study, meaning neither the doctors nor the participants know who gets the real medicine or a placebo (a harmless pill that does nothing). The study also includes a long-term part where everyone gets the real medicine. To join, you must be 18-75 years old and have moderate to severe UC. You cannot join if you have other conditions like Crohn’s Disease or certain infections.
- Total study duration is up to 168 weeks.
- Includes a treatment period lasting up to 158 weeks.
- You may receive a placebo or the actual drug.
Discuss with your doctor to know if this study is a good fit for you.
