Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Induction Period: Percentage of Participants Who Achieved Clinical Remission at Week 14
Time Frame: At Week 14
Clinical remission was defined as total Mayo Score ≤2, with no individual subscore >1. Mayo Score was a tool designed to measure disease activity for UC. The score ranges from 0 - 12 and was a composite of the four following assessments of disease activity: stool frequency subscore, rectal bleeding subscore, endoscopy subscore, and physician's global assessment (PGA) subscore. Each of the four assessments was rated with a score from 0 to 3, with higher scores indicating more severe disease activity. Percentages have been rounded off to the nearest whole number.
At Week 14
Induction Period: Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
Time Frame: From initiation of study treatment to either first dose in the chronic period or end of safety follow-up, whichever occurs first. (Approximately 16 weeks plus 12-week safety follow-up, if applicable.)
TEAEs was defined as all events that started on or after the first dosing day and time, but before the last dose plus the lag time. An adverse event (AE) was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study intervention. Results may differ from publications that used Week 14 as the end of the AE reporting timeframe.
From initiation of study treatment to either first dose in the chronic period or end of safety follow-up, whichever occurs first. (Approximately 16 weeks plus 12-week safety follow-up, if applicable.)
Induction Period: Number of Participants With Serious Adverse Events (SAEs)
Time Frame: From initiation of study treatment to either first dose in the chronic period or end of safety follow-up, whichever occurs first. (Approximately 16 weeks plus 12-week safety follow-up, if applicable.)

An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study intervention. SAE was defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity; or is a congenital anomaly/birth defect.
