Primary Outcome Measures
NameTimeMethod
Change From Baseline in Adapted Mayo Score (MCS) at Week 12Baseline and Week 12

The adapted MCS was used to measure disease activity of ulcerative colitis. It consisted of 3 subscores (stool frequency, rectal bleeding, and findings of endoscopy), each of which was rated on a scale from 0 to 3, indicating normal to severe. The adapted MCS was calculated as the sum of the 3 subscores, and the overall score values ranged from 0 to 9, with a higher score indicating more severe disease. Multiple imputation method was used to handle missing data.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants Who Achieved Endoscopic Improvement at Week 12Week 12

For determination of the endoscopic subscore of the MCS, a flexible proctosigmoidoscopy, performed with a videoendoscope following a cleansing prep (oral or rectal cathartic) was performed at screening (within 10 days prior to administration of the first dose of study drug) and the Week 12 visit. This efficacy procedure assessed endoscopic mucosal appearance. The results were rated on a scale from 0 to 3, indicating normal to severe. Endoscopic improvement was defined as Mayo endoscopic subscore (using findings of flexible proctosigmoidoscopy) of ≤1 point. Multiple imputation method was used to handle missing data.

Change From Baseline in Total Mayo Score (TMS) at Week 12Baseline and Week 12

The TMS was used to measure disease activity of ulcerative colitis. It consisted of 4 subscores \[stool frequency, rectal bleeding, findings of endoscopy (flexible proctosigmoidoscopy), and Physician's Global Assessment (PGA) score\], each of which was rated on a scale from 0 to 3, indicating normal to severe. The TMS was calculated as the sum of the 4 subscores, and the overall score values ranged from 0 to 12, with a higher score indicating more severe disease. Multiple imputation method was used to handle missing data.

Change From Baseline in 2-component MCS at Week 12Baseline and Week 12

The 2-component MCS was used to measure disease activity of ulcerative colitis. It consisted of 2 subscores (rectal bleeding and findings on endoscopy), each of which was rated on a scale from 0 to 3, indicating normal to severe. The 2-component MCS was calculated as the sum of the 2 subscores, and the overall score value ranged from 0 to 6, with a higher score indicating more severe disease. Multiple imputation method was used to handle missing data.
