•4\.Evidence of UC extending proximal to the rectum (\= 15 cm of involved colon).
•5\.Moderately to severely active UC as defined by (5a and 5b must be met):
•(a) Stool Frequency and Rectal Bleeding subscores will be obtained during Screening on an eDiary. The following criteria must also be met:
•i. Average daily mMS Stool Frequency subscore \= 1 AND
•ii. Average daily mMS Rectal Bleeding subscore \= 1
•(b) Modified Mayo endoscopic subscore of \= 2 based on a full colonoscopy within 14 days prior to initial IRT randomization.
•6\.Participant had an inadequate response or intolerance to intervention with conventional treatment (oral aminosalicylates, oral CS, azathioprine, methotrexate, or 6 mercaptopurine) or prior biological treatment or demonstrated CS dependence for the treatment of UC. For participants who have previously used biological treatment, a participant may have failed up to 3 biologics that include up to 2 different mechanisms of action.

•1\. Participant has UC limited to the rectum (ie, not beyond 15 cm of the anal verge)
•2\.Current diagnosis of fulminant colitis, a diagnosis of CD or indeterminate colitis, presence or history of a fistula consistent with CD, primary sclerosing cholangitis, celiac disease, or untreated bile acid malabsorption.
