•Have moderately to severely active UC as defined by a modified Mayo score (mMS) of 5 to 9 points and endoscopic subscore (ES) of 2 to 3 (confirmed by central review) within 21 days before baseline.

•Participants with a history of UC for greater than or equal to 8 years who have had a surveillance colonoscopy completed within 1 year prior to baseline must have documented negative results for colorectal dysplasia and cancer.

•Have obesity, [body mass index (BMI) 30 kilograms per meter squared (kg/m2)]
