Study Details:
Study description/explanation of participation:
Approximately 99 participants will join the study at research sites around the world. The main study may last up to 1 year and is followed by an optional long-term extension period of up to 2 years. During the first year of the study, the study drug will be studied along with a placebo. You will have a 66% chance of receiving the study drug.
During the optional long-term extension, every participant will receive study medication.
Description of treatment or intervention (mechanism of action):
SAR442970 is a novel, investigational medication that simultaneously targets two different known pathways of CD to potentially improve disease control. This study will help us learn more about SAR442970, how it works in people with UC, and any potential side effects it may have. The study medication is given just under the skin with a short needle (subcutaneous injection).
Patient Participation Requirements:
Participants will visit the study center every 2 weeks to receive the study drug and have various assessments, such as physical exam, blood draws, providing stool samples, etc.
Participants will be asked to complete a daily electronic study diary (at home). There will also be questionnaires spread throughout the study to complete.
Possible risks and side effects:
There is no certainty that you will have any benefit from taking part in the study. The information collected during this study may help doctors better treat patients with Ulcerative Colitis in the future. Further details are provided on the informed consent form which the study site will provide and discuss with participants.
