Summary

This trial studies how well a new drug works to treat ulcerative colitis in people who aren't responding to other treatments.

Who is the study for?
This trial is for men and women at least 16 years old with ulcerative colitis (UC) that's moderately to severely active. They should have tried other UC treatments like corticosteroids, immunosuppressants, or biologics without success or couldn't tolerate them. Participants need to understand the study and consent to it, use effective birth control if necessary, and be able to follow the study schedule.
What is being tested?
ABTECT-2 is testing ABX464 at doses of 25 or 50 mg daily against a placebo in people with UC who haven't responded well to standard therapies. The goal is to see if ABX464 can induce clinical remission. This multicenter trial randomly assigns participants into different groups in a controlled environment.
What are the potential side effects?
While specific side effects for ABX464 are not listed here, common side effects from drugs treating UC may include headache, nausea, fatigue, abdominal pain, and potential increased risk of infection.
