biopsy results consistent with the diagnosis of UC in the assessment of the
Investigator, must be available.

- Participant meets the following disease activity criteria: Active UC with an Adapted
Mayo score of 5 to 9 points and endoscopic subscore of 2 to 3 (confirmed by central
review).

- History of inadequate response, loss of response, or intolerance to one or more of the
approved biologic therapies: infliximab, adalimumab, golimumab, vedolizumab, and/or
tofacitinib (Note: If tofacitinib was received in a clinical trial, subject must have
received open-label drug).

Exclusion Criteria:

- Participant having an active, chronic, or recurrent infection that based on
Investigator's clinical assessment makes the participant an unsuitable candidate for
the study.

- Participant having any malignancy except for successfully treated non-metastatic
cutaneous squamous cell or basal cell carcinoma or localized carcinoma in situ of the
