Inclusion criteria

Inclusion criteria: Inclusion Criteria:- A diagnosis of UC for >=3 months. Participants with moderate to severe active UC as defined by a Total Mayo Score of >=6, and an endoscopic subscore of >=2. Active disease beyond the rectum (>15 cm of active disease from the anal verge at the screening endoscopy). Must have failed or been intolerant to at least one of the following class of medications: steroids, immunosuppressants, anti-TNFs, anti-integrin inhibitors, anti- IL-12/23 inhibitors, or JAK inhibitors.

Exclusion criteria

Exclusion criteria: Exclusion Criteria: Participants with a diagnosis of ischemic colitis, infectious colitis, radiation colitis, microscopic colitis, indeterminate colitis, or findings suggestive of Crohn's disease (eg, skip lesions, fistulae/perianal disease, non-necrotizing granulomas, etc.). Participants with an imminent need for surgery or with elective surgery scheduled to occur during the study Chest Radiograph showing abnormalities: The study will accept a Chest x-ray or computed tomography scan of the chest examination performed up to 12 weeks prior to screening if available. 12-lead electrocardiogram (ECG) that demonstrates clinically relevant abnormalities that may affect participant safety or interpretation of study results Infected with tuberculosis, (TB): Any evidence of untreated latent or active TB infection.

Primary

MeasureTime frame
safety efficacy 1. Proportion of participants achieving clinical remission at Week 14. 2. Incidence and severity of treatment emergent adverse events (TEAEs) during the induction period. 3. Incidence of serious adverse events (SAEs) during the induction period. 4. Incidence of AEs or SAEs leading to discontinuation during the induction period. 5. Incidence of clinically significant abnormalities in vital signs, electrocaridograms, (ECGs) and laboratory values during the induction period. *Time Frames of 1 to 5 above are weeks 0-14 6. Incidence and severity of treatment emergent adverse events (TEAEs) during the chronic therapy period. 7. Incidence of serious adverse events (SAEs) during the chronic therapy period. 8. Incidence of AEs or SAEs leading to discontinuation during the chronic therapy period. 9. Incidence of clinically significant abnormalities in vital signs, ECGs and laboratory values during the chronic therapy period. *Time frames of 6 to 9 are weeks 14-64
