Inclusion criteria

Inclusion criteria: -Diagnosis of ulcerative colitis (UC) established at least 12 weeks before screening including both endoscopic evidence and a histopathology report consistent with a diagnosis of UC -Moderately to severely active UC, defined as a baseline (Week I-0) modified Mayo score of 5 to 9, inclusive, using the endoscopy subscore obtained during the central review of the screening video endoscopy - An endoscopy subscore greater than or equal to (>=) 2 as obtained during central review of the screening video endoscopy - For adolescent participants >=12 to less than (=40 kilograms (kg) at baseline (Week I-0) - A female participant of childbearing potential must have a negative highly sensitive serum pregnancy test (beta-human chorionic gonadotropin [beta-hCG]) at screening and a negative urine pregnancy test at Week I-0 prior to administration of study intervention and agree to further pregnancy tests - Demonstrated an inadequate response, loss of response, or failure to tolerate previous conventional therapy (advanced drug therapy [ADT]-naive) or advanced therapy defined as biologics and/or advanced oral agents for the treatment of UC (ADT-inadequate responder [IR]) as defined in the protocol

Exclusion criteria

Exclusion criteria: - Participants with current known complications of UC such as fulminant colitis, toxic megacolon, or any other manifestation that might require colonic surgery while enrolled in the study - Presence of a stoma - Presence or history of a fistula - Colonic resection within 24 weeks before baseline or any other intra-abdominal or other major surgery performed within 12 weeks before baseline - History of extensive colonic resection (that is, less than [<]30 centimeter [cm] of colon remaining) or colonic resection that could impair the use of disease severity assessments (for example Mayo Score) to assess response to study intervention

Design outcomes

Primary

MeasureTime frame
1. Double-blind (DB) Induction Study: Percentage of Adult Participants in Clinical Remission at Week I-12 [Time Frame: At Week I-12] Percentage of adult participants in clinical remission at Week I-12 will be reported. Clinical remission is defined as stool frequency subscore of 0 or 1, a rectal bleeding subscore of 0, and an endoscopy subscore of 0 or 1. 2. DB Maintenance Study: Percentage of Adult Participants in Clinical Remission at Week M-40 [Time Frame: At Week M-40] Percentage of adult participants in clinical remission at Week M-40 will be reported. Clinical remission is defined as stool frequency subscore of 0 or 1, a rectal bleeding subscore of 0, and an endoscopy subscore of 0 or 1. 3. Open-Label (OL) Maintenance Phase: Percentage of Adolescent Participants in Clinical Remission at Week M-40 [Time Frame: At Week M-40] Percentage of adolescent participants in clinical remission at Week M-40 will be reported. Clinical remission is defined as stool frequency subscore of 0 or 1, a rectal bleeding subscore of 0, and an endoscopy subscore of 0 or 1.
