• Documented clinical diagnosis of UC for ≥ 3 months prior to Screening. The diagnosis of UC must be confirmed by endoscopic and histologic evidence; If a histopathology report is not available in the source records, a biopsy for a local histopathology evaluation (to obtain a report) can be obtained during the screening endoscopy procedure
• Moderately to severely active UC, defined as:; mMS of 5 to 9 (inclusive), AND; ES ≥ 2, AND; RB ≥ 1
• Participants must satisfy at least one of the criteria listed under item a OR at least one of the criteria listed under item b:; History of inadequate response or loss of response, or intolerance to at least one prior UC therapy, defined as: i. Oral prednisone ≥ 40 mg/day (or equivalent) or budesonide ≥ 9 mg/day for ≥ 2 weeks
• Corticosteroid dependence: unable to taper < 10 mg/day prednisone equivalent within 3 months, or relapse within 3 months of discontinuation
• Immunosuppressants: azathioprine ≥ 2 mg/kg/day, 6-mercaptopurine (6-MP) ≥ 1.0 mg/kg/day (or therapeutic 6-thioguanine nucleotide [6-TGN] level) for ≥ 12 weeks, or methotrexate ≥ 15 mg/week subcutaneous or intramuscular
• Approved advanced therapies at the approved labelled dose:
• Anti-tumor necrosis factor (TNF), anti-integrin (vedolizumab), or anti-IL-12/23 for at least 8 weeks; anti-IL 23 for at least 12 weeks
• Janus kinase (JAK) inhibitor for at least 8 weeks; sphingosine-1-phosphate receptor (S1PR) modulator for at least 12 weeks; Note: Demonstration of intolerance requires no minimum dose nor duration of use
• Currently receiving one or more of the following treatments: i. Stable oral prednisone at ≤ 20 mg/day (or equivalent) or budesonide ≤ 9 mg for ≥ 2 weeks prior to randomization
• Stable dose of thiopurine (azathioprine or 6-MP) for ≥ 4 weeks prior to randomization, and have started the treatment ≥ 12 weeks prior to randomization
• Stable dose of oral aminosalicylates for ≥ 2 weeks prior to randomization
