  • e. any other biologics (including ustekinumab and vedolizumab) for the treatment of UC within 12 weeks.
  • 2. Have received orally administered azathioprine or 6-mercaptopurine that has been stable for <8 weeks. Doses of oral drugs must remain stable until the last dose of study drug.
  • 3. Have received orally administered 5-aminosalicylic acid, sulphasalazine, or low-dose corticosteroids (prednisolone =20 mg/day or equivalent) that have been stable for <5 weeks. Doses of oral drugs must remain stable until the last dose of study drug.
  • 4. 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.
  • 5. Have Crohn’s disease, indeterminate colitis, ischaemic colitis, fulminant colitis, toxic megacolon, chronic (as determined by the investigator) pancolitis, confined proctitis (distal, =15 cm), or symptomatic intestinal stenosis.

  • 12. Have a history of any disease or condition (including mental and emotional conditions) that, in the opinion of the investigator (or designee), would affect participation in this study.
  • 13. Have clinically significant abnormal liver function tests, including:

  • Note: Liver function tests may be repeated once, at the discretion of the investigator (or designee).
  • 14. Have other clinically significant abnormal clinical laboratory results that, in the opinion of the investigator, preclude participation in the study, including:
