• Anti TNF or anti-integrin therapy.
10. For participants in the US and the EU: have had an inadequate response or intolerance to TNF inhibitors.
11. Stable doses of the following therapies for UC for designated time and throughout study (Note: The following therapies for UC are not required, however allowed, and if taken, must remain stable for those subjects who are taking them at the time of enrollment):

13. Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
14. No contraception methods are required for male participants in this study, as the calculated safety margin is ≥100 fold between the estimated maternal exposure due to seminal transfer and the no observed adverse effect level (NOAEL) for serious manifestations of developmental toxicity in nonclinical studies.
A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least 1 of the following conditions applies:
- Is not a woman of childbearing potential (WOCBP) (see definitions in Section 4.3.4.1) OR
Is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of <1% per year), as described in Section 4.3.4.2,
during the intervention period and for at least 12 weeks after the last dose of study intervention. If a highly effective method that is user dependent
is chosen, a second effective method of contraception, as described in Section 4.3.4.2, must also be used. The investigator should evaluate the
effectiveness of the contraceptive method in relationship to the first dose of study intervention.
