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 30 sites globally.
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.
Eligibility Criteria
Inclusion Criteria
- Diagnosis of ulcerative colitis (UC) for at least 90 days prior to Baseline. Appropriate documentation of biopsy results consistent with the diagnosis of UC in the assessment of the Investigator, must be available.
- Participant meets the following disease activity criteria: Active UC with an Adapted Mayo score of 5 to 9 points and endoscopic subscore of 2 to 3 (confirmed by central review).
- Demonstrated inadequate response to, loss of response to, or intolerance to at least one of the following: oral aminosalicylates, corticosteroids, immunosuppressants and/or targeted immunomodulators (including biologics and non-biologics)
Exclusion Criteria
