Study Endpoints

Primary Endpoints

Percentage of Participants in Clinical Remission at Week 12
Week 12

Clinical remission was defined as a Total Mayo Score of less than or equal (\<=) 2 points with no individual subscore exceeding 1 point and rectal bleed subscore of 0 or 1. The Mayo Score is a tool designed to measure disease activity for ulcerative colitis (UC). Scoring ranges from 0 to 12 points and consists of 4 subscores, each graded 0 to 3 with higher score indicating more severe disease activity. Endoscopic readings from the local and the central reader were considered for analysis. The central reading was used as the primary analysis and the local readings were used for the sensitivity analyses.

Number of Participants With On-Treatment Adverse Events (AEs), AEs Led to Withdrawal, and Serious Adverse Events (SAEs)
From start of study treatment up to Week 72 (Treatment Period)

AEs included adverse drug reactions, illnesses with onset during the study, exacerbation of previous illnesses, clinically significant changes in physical examination findings and abnormal objective test findings (ECG, laboratory). An SAE was defined as any AE at any dose that resulted in death; was life threatening (immediate risk of death); required in-subject hospitalization or prolongation of existing hospitalization; resulted in a persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions); or resulted in congenital anomaly/birth defect.

Percentage of Participants With Crohn's Disease Activity Index (CDAI) 70 Response Rate
Week 8 and week 12

Crohn's Disease Activity Index (CDAI) is a number which consists of information collected from a 7-day diary from the participants regarding symptoms. Remission is considered a score of 150 or less. Active disease is considered 200 or greater. A response to therapy is considered a decline in CDAI score of 70-points from baseline. CDAI response rate at week 8 and week 12 was measured between the investigational product group and the placebo group.
