Key exclusion criteria
* Have used any biologics or Janus kinase (JAK) inhibitors including, but not limited to, anti TNF a biologics or tofacitinib for the treatment of UC.
* Have used any purine analogues (azathioprine, mercaptopurine, or thiopurines) or immunosuppressants (methotrexate or cyclosporine) for the treatment of UC within 12 weeks or have any history of nonresponse to these medications.
* Have used any rectal therapy for the treatment of UC with exception of rectal suppository of 5-aminosalicylic acid, or any intravenous corticosteroids within 2 weeks prior to Day 1.
* Have received oral and/or rectal suppository 5-aminosalicylic acid, oral sulphasalazine, or low-dose oral corticosteroids that have been stable for <4 weeks. Doses of the drugs must remain stable until the last dose of study drug.
* Have received any other concomitant medications for UC that have been stable (ie, have not started dosing with a new drug or had a change to their dosing regimen) for <7 days or 5 half lives, whichever is longer, prior to Day 1.
* Have Crohn's disease, indeterminate colitis, ischaemic colitis, fulminant colitis, toxic megacolon, chronic pancolitis, or symptomatic intestinal stenosis.
* Have a history of extensive colonic resection (subtotal or total colectomy) or are anticipated to require surgical intervention for UC.
