This study is researching a new treatment called VE202 for people with mild to moderate ulcerative colitis (UC). UC is a condition that causes swelling and sores in the colon. In the study, some people will get VE202 and others will get a placebo, which is a pill that doesn't have any medicine, to compare results. The study lasts for 8 weeks or 2 weeks, and then participants will be monitored for a year to make sure they are safe.

Key Points to Consider:

• The study lasts up to 8 weeks, with a year-long safety check afterward.
• Participants must be between 18 and 75 years old and have not used certain other UC treatments before.
• Participants should not have other bowel diseases or allergies to the study medication.

Participants must have had UC for at least 3 months and should not have had certain treatments like probiotics or specific surgeries recently. During the study, any current UC medications should be stable for a few weeks before starting the trial.
