Percentage of Participants in Clinical Remission at Week 12
Percentage of participants in clinical remission at Week 12 was reported. Clinical remission is defined as a Mayo stool frequency subscore of 0 or 1 and not increased from baseline, a Mayo rectal bleeding subscore of 0, and a Mayo endoscopy subscore of 0, or 1 with no friability present on the endoscopy. Mayo stool frequency subscore was determined on the average number of stools more than normal in 24 hours, score ranged from 0 (normal number of stools) to 3 (5 or more stools more than normal), higher score indicated more severity. Mayo rectal bleeding subscore ranged from 0 (no blood seen) to 3 (blood alone passed), higher score indicated more severity. Mayo endoscopy subscore ranged from 0 (normal or inactive disease) to 3 (severe disease), higher score indicated more severity.
Time frame: Week 12
Percentage of Participants in Symptomatic Remission at Week 12
Percentage of participants in symptomatic remission at Week 12 was reported. Symptomatic remission is defined as a stool frequency subscore of 0 or 1 and not increased from baseline, and a rectal bleeding subscore of 0. Mayo stool frequency subscore was determined on the average number of stools more than normal in 24 hours, score ranged from 0 (normal number of stools) to 3 (5 or more stools more than normal), higher score indicated more severity. Mayo rectal bleeding subscore ranged from 0 (no blood seen) to 3 (blood alone passed), higher score indicated more severity.
Time frame: Week 12
Percentage of Participants With Endoscopic Improvement at Week 12
Percentage of participants with endoscopic improvement at Week 12 was reported. Endoscopic improvement is defined as an endoscopy subscore of 0, or 1 with no friability present on the endoscopy. Mayo endoscopy subscore ranged from 0 (normal or inactive disease) to 3 (severe disease), higher score indicated more severity.

Percentage of participants in clinical response at Week 12 was reported. Clinical response is defined as a decrease from baseline in the modified Mayo score by greater than or equal to (\>=) 30 percent (%) and \>=2 points, with either a \>=1-point decrease from baseline in the rectal bleeding subscore or a rectal bleeding subscore of 0 or 1. The modified Mayo scores consisted of 3 subscores: stool frequency, rectal bleeding and endoscopic subscore, each subscore graded from 0 (normal) to 3 (severe) with higher scores indicating more severe disease. These individual subscores were summed up to give a total modified Mayo score range of 0 (normal) to 9 (severe disease), where higher scores indicated more severe disease activity.
Time frame: Week 12
Percentage of Participants With Histologic-endoscopic Mucosal Improvement at Week 12
Percentage of participants with histologic-endoscopic mucosal improvement at Week 12 was reported. Histologic-endoscopic mucosal improvement is defined as achieving a combination of histologic improvement and endoscopic improvement. Histologic improvement is defined as neutrophil infiltration in less than (\<) 5% of crypts, no crypt destruction, and no erosions, ulcerations or granulation tissue according to the Geboes grading system. Endoscopic improvement is defined as an endoscopy subscore of 0, or 1 with no friability present on the endoscopy. Mayo endoscopy subscore ranged from 0 (normal or inactive disease) to 3 (severe disease), higher score indicated more severity.
Time frame: Week 12
Percentage of Participants in Clinical Remission at Week 24
Percentage of participants in clinical remission at Week 24 was reported. Clinical remission is defined as a stool frequency subscore of 0 or 1 and not increased from baseline, a rectal bleeding subscore of 0, and an endoscopy subscore of 0, or 1 with no friability present on the endoscopy. Mayo stool frequency subscore was determined on the average number of stools more than normal in 24 hours, score ranged from 0 (normal number of stools) to 3 (5 or more stools more than normal), higher score indicated more severity. Mayo rectal bleeding subscore ranged from 0 (no blood seen) to 3 (blood alone passed), higher score indicated more severity. Mayo endoscopy subscore ranged from 0 (normal or inactive disease) to 3 (severe disease), higher score indicated more severity.

Mayo stool frequency subscore was determined on the average number of stools more than normal in 24 hours, score ranged from 0 (normal number of stools) to 3 (5 or more stools more than normal), higher score indicated more severity. Mayo rectal bleeding subscore ranged from 0 (no blood seen) to 3 (blood alone passed), higher score indicated more severity.

Percentage of Participants With Endoscopic Improvement at Week 24
Percentage of participants with endoscopic improvement at Week 24 was reported. Endoscopic improvement is defined as an endoscopy subscore of 0, or 1 with no friability present on the endoscopy.
