• Status: Not yet recruiting
• Trial end date: 2025-08-25
• Target enrollment: 0
• Participant gender: All

Summary

Ulcerative colitis (UC) is a type of inflammatory bowel disease that causes inflammation and bleeding from the lining of the rectum and colon (large intestine). This study will assess how safe and effective ABBV-668 is in treating adult participants with UC. Adverse events and change in disease activity will be assessed.

ABBV-668 is an investigational drug being developed for the treatment of moderate to severe UC. Approximately 40 adult participants diagnosed with UC will be enrolled in approximately 23 sites across Belgium and the United States.

Participants will receive oral capsules of ABBV-668 twice daily for 16-weeks and will undergo a 30 day follow-up period.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, checking for side effects and completing questionnaires.
