ClinConnect Summary
This clinical trial is looking at a new treatment called SAR442970 for adults with moderate to severe Ulcerative Colitis, a condition that causes inflammation in the colon. The goal is to find out how effective this treatment is compared to a placebo (a "sugar pill" that has no active ingredients) over a period of up to 169 weeks. Participants in the study will be randomly assigned to receive either the medication or the placebo, and the study will help researchers understand which doses work best and how safe the treatment is.
To be eligible for this trial, participants must be between 18 and 75 years old and have been diagnosed with active Ulcerative Colitis for at least three months. They should have previously tried other treatments without success or have not responded well to advanced therapies for Ulcerative Colitis. Participants will need to meet specific health criteria to ensure their safety during the study. If chosen, they can expect to receive treatment for almost four years, complete regular check-ups, and contribute to important research that could benefit others with this condition.

- • Positive Hepatitis C Virus (HCV) antibody
- • Screening laboratory and other analyses showing abnormal results
- • History of any other condition which, in the opinion of the Investigator, would put the participant at risk by participation in the protocol
- • The above information is not intended to contain all considerations relevant to a participant's potential participation in a clinical trial
- • NOTE - Additional criteria apply, please contact the investigator for more information
