Percentage of Participants with Clinical Remission at Week 56
Percentage of participants with clinical remission as assessed by modified Mayo score at Week 56 among participants who were induction responders will be reported. Clinical remission per modified Mayo score is defined as a stool frequency subscore of 0 or 1, a rectal bleeding subscore of 0, and an endoscopy subscore of 0 or 1 with no friability present on the endoscopy, where the stool frequency subscore has not increased from induction baseline.
Time frame: Week 56
Percentage of Participants with Clinical Response at Week 12
Percentage of participants with clinical response as assessed by modified Mayo score at Week 12 will be reported. Modified Mayo score is a 3-component (stool frequency, rectal bleeding, and endoscopy subscores) assessment and does not include the physician's global assessment. A decrease from baseline in the modified Mayo score by greater than or equal to (\>=) 30 percent and \>= 2 points, with either a decrease from baseline in the rectal bleeding subscore of \>= 1 or a rectal bleeding subscore of 0 or 1.
Time frame: Week 12
Percentage of Participants with Clinical Remission at Week 12
Percentage of participants with clinical remission at Week 12 as assessed by modified Mayo score will be reported. Clinical remission per modified Mayo score is defined as a stool frequency subscore of 0 or 1, a rectal bleeding subscore of 0, and an endoscopy subscore of 0 or 1 with no friability present on the endoscopy, where the stool frequency subscore has not increased from induction baseline.
Time frame: Week 12
Percentage of Participants With Pediatric Ulcerative Colitis Activity Index (PUCAI) Remission at Week 12
Percentage of participants with PUCAI remission at Week 12 will be reported. It comprises 6 scales and ranges between 0 and 85 points. The scales are abdominal pain, rectal bleeding, stool consistency, number of stools, nocturnal bowel movement, and activity level. The PUCAI score is calculated as the sum of the 6 subscores. A PUCAI score of less than (\<) 10 indicates remission.
