Design outcomes

Primary

MeasureTime frameDescription
Combination Phase: Percentage of Participants Who Achieved Clinical Response at Week 12Week 12Clinical response was defined as a decrease from baseline in the Mayo score greater than or equal to (\>=) 30 percent (%) and \>=3 points with either a decrease from baseline in the rectal bleeding subscore (RBS) \>=1 or a RBS of 0 or 1. The Mayo score was calculated as the sum of 4 subscores (stool frequency, rectal bleeding, physician's global assessment, and endoscopy findings - each with score range of 0 (normal activity) to 3 (severe activity) and a total score range of 0 to 12 points. A score of 3 to 5 points indicates mildly active disease, a score of 6 to 10 points indicates moderately active disease, and a score of 11 to 12 points indicates severely active disease. Higher scores indicate more severity. This outcome measure was analyzed for combination phase only as preplanned in the protocol.

Secondary

MeasureTime frameDescription
Combination Phase: Percentage of Participants Who Achieved Clinical Remission at Week 12Week 12Clinical remission was defined as the Mayo score less than or equal to (\<=) 2 with no individual subscore greater than (\>) 1. The Mayo score was calculated as the sum of 4 subscores (stool frequency, rectal bleeding, physician's global assessment, and endoscopy findings) each with score range of 0 (normal activity) to 3 (severe activity) and a total score range of 0 to 12 points. A score of 3 to 5 points indicates mildly active disease, a score of 6 to 10 points indicates moderately active disease, and a score of 11 to 12 points indicates severely active disease. Higher scores indicate more severity. This outcome measure was analyzed for combination phase only as preplanned in the protocol.

Outcome results

Primary

Combination Phase: Percentage of Participants Who Achieved Clinical Response at Week 12

Clinical response was defined as a decrease from baseline in the Mayo score greater than or equal to (\>=) 30 percent (%) and \>=3 points with either a decrease from baseline in the rectal bleeding subscore (RBS) \>=1 or a RBS of 0 or 1. The Mayo score was calculated as the sum of 4 subscores (stool frequency, rectal bleeding, physician's global assessment, and endoscopy findings - each with score range of 0 (normal activity) to 3 (severe activity) and a total score range of 0 to 12 points. A score of 3 to 5 points indicates mildly active disease, a score of 6 to 10 points indicates moderately active disease, and a score of 11 to 12 points indicates severely active disease. Higher scores indicate more severity. This outcome measure was analyzed for combination phase only as preplanned in the protocol.

Time frame: Week 12

Population: Efficacy analyses were based on the full analysis set (FAS), which included all randomized participants who received at least 1 (partial or complete) dose of study intervention.
