Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Evidence of biomarker enrichment at time of screening.
* Moderately to severely active UC, defined as a baseline modified Mayo score of 5 to 9, inclusive, using the Mayo endoscopic subscore assigned during the concurrent local and central reading of the video endoscopy.
* Has a screening endoscopy with ≥2 endoscopic subscore in the Mayo score component assessment as determined by concurrent local and central reading of the video endoscopy.
* Has a baseline rectal bleeding subscore of ≥1 and baseline a stool frequency score of ≥1 as determined by the Mayo score component assessment.
* Participants with inadequate response/non-response, loss of response, or are intolerant of standard biologic therapy for their UC AND/OR Inadequate or non-responders, have shown loss of response, or are intolerant to at least 1 of the following treatments: oral corticosteroids (≤20 mg/day), 5-aminosalicylic acid (ASA) compounds, immunomodulators, small molecules.
Exclusion Criteria
* Severe extensive colitis as evidenced by:
* Current hospitalization
* Likely to require surgery for the treatment of UC within 12 weeks of Screening Visit
* UC limited to the rectum only or to \<20 cm of the colon as determined by central reading.
* Presence of an ileal pouch, ostomy, stoma or fistula or history of a fistula.
* Require, or required within the 2 months before screening, surgery for active gastrointestinal bleeding, peritonitis, intestinal obstruction, or intra-abdominal or pancreatic abscess requiring surgical drainage, or other conditions possibly confounding the evaluation of benefit from study agent treatment.
* Has a prior medical history of eosinophilic colitis.
* Participants with abdominal abscess, fulminant disease, or toxic megacolon.
* Participants with intestinal failure or short bowel syndrome.
* Presence of symptomatic colonic or small bowel obstruction, confirmed by objective radiographic or endoscopic evidence of a stricture with resulting obstruction (dilation of the colon or small bowel proximal to the stricture on barium radiograph or an inability to traverse the stricture at endoscopy).
* History of extensive colonic resection (eg, less than 30 cm of colon remaining) that would prevent adequate evaluation of the effect of study agent on clinical disease activity.
* History of colonic mucosal dysplasia or presence of adenomatous colonic polyps not removed OR presence of colonic mucosal dysplasia or adenomatous colonic polyps not removed during colonoscopy at screening visit.
* If the participant has extensive colitis for ≥8 years or disease limited to left side of colon (ie, distal to splenic flexure) for \>10 years, regardless of age, a colonoscopy within 1 year of the screening visit is required to survey for dysplasia. Participants with dysplasia or cancer identified on biopsies will be excluded.
* Diagnosis of indeterminate colitis, microscopic colitis, ischemic colitis, or Crohn's disease or clinical findings suggestive of Crohn's disease.
