Active disease beyond the rectum (>15 cm of active disease from the anal verge at the screening endoscopy). Must have failed or been intolerant to at least one of the following class of medications: steroids, immunosuppressants, anti-TNFs, anti-integrin inhibitors, anti- IL-12/23 inhibitors, or JAK inhibitors.
Exclusion criteria
Exclusion criteria: Exclusion Criteria: Participants with a diagnosis of ischemic colitis, infectious colitis, radiation colitis, microscopic colitis, indeterminate colitis, or findings suggestive of Crohn's disease (eg, skip lesions, fistulae/perianal disease, non-necrotizing granulomas, etc.).
