Outcomes
Primary outcome [1] 0 0
Percentage of Participants Who Achieved Clinical Remission Per Modified Mayo Clinic Score (MCS) at Week 10
Assessment method [1] 0 0
The modified MCS is a scoring system for assessment of ulcerative colitis (UC) activity and is composed of subscores from endoscopy (range: 0 to 3, where 0 = normal or inactive disease and 3 = severe disease \[spontaneous bleeding, ulceration\]), rectal bleeding (range: 0 to 3, where 0 = no blood seen and 3 = blood alone passes), stool frequency (range: 0 to 3, where 0 = normal number of stools and 3 = at least 5 or more stools more than normal), and physician's global assessment (PGA) (range: 0 to 3, where 0 = normal and 3 = severe disease). Total score for MCS ranges from 0 to 12 (sum of all subscores), with higher scores indicating higher disease activity. Clinical remission per modified MCS is defined as stool frequency subscore = 1 and not greater than baseline, rectal bleeding subscore of 0, and endoscopic subscore = 1 at Week 10.

Percentage of Participants Who Achieved Endoscopic Response at Week 10
Assessment method [1] 0 0
Endoscopic response was defined as an endoscopic subscore of = 1 at Week 10. Endoscopic subscore is a part of the modified MCS which is a scoring system for assessment of UC activity. Endoscopic subscore range: 0 to 3, where 0 = normal or inactive disease, 1 = mild disease (erythema, decreased vascular pattern), 2 = moderate disease (marked erythema, lack of vascular pattern, friability, erosions), and 3 = severe disease (spontaneous bleeding, ulceration).

Total score for MCS ranges from 0 to 12 (sum of all subscores), with higher scores indicating higher disease activity. MCS response is defined as a decrease from baseline of = 3 points and at least 30% in MCS, in addition to a = 1 point decrease from baseline in the rectal bleeding subscore or a rectal bleeding subscore = 1 at Week 10.

Percentage of Participants Who Achieved Histologic Remission Based Upon the Geboes Scale at Week 10
Assessment method [4] 0 0
Geboes histologic remission was assessed using the Geboes histologic scores to identify histologic changes in ulcerative colitis. Possible scores are Grade 0:Architectural changes(0.0=No abnormality to 0.3=Severe diffuse or multifocal abnormalities); Grade 1:Chronic inflammatory infiltrate(1.0=No increase to 1.3=Marked increase);Grade 2A:Eosinophils in lamina propria(2A.0=No increase to 2A.3-=Marked increase; Grade 2B:Neutrophils in lamina propria(2B.0= No increase to 2B.3=Marked increase);Grade 3:Neutrophils in epithelium (3.0=None to 3.3=\>50% crypts involved);Grade 4:Crypt destruction(4.0=none to 4.3=Unequivocal crypt destruction),and Grade 5:Erosions and ulcerations:(5.0=No erosion, ulceration or granulation to 5.4=Ulcer or granulation tissue). Histologic remission defined as having Grade 0 of = 0.3, Grade 1 of = 1.1, Grade 2a of = 2A.3, Grade 2b of 2B.0, Grade 3 of 3.0, Grade 4 of 4.0, and Grade 5 of 5.0. Geboes score ranges from 0 to 5.4. Lower values indicate better outcome.

Percentage of Participants Who Experienced Treatment-emergent Adverse Events (TEAEs)
Assessment method [5] 0 0
Treatment-emergent adverse events (TEAEs) for the Blinded Treatment phase are either defined as AEs with an onset date on or after the Blinded Treatment phase study drug start date and no later than 30 days after permanent discontinuation of the Blinded Treatment phase study drug if no Open-label Treatment phase study drug was taken, or any AEs with an onset date on or after the Blinded Treatment phase study drug start date and before the Open-label Treatment phase study drug start date if Open-label Treatment phase study drug was taken and/or any AEs leading to premature discontinuation of Blinded Treatment phase study drug. TEAEs for the Open-label Treatment phase are either defined as AEs with an onset date on or after the Open-label Treatment phase study drug start date and no later than 30 days after permanent discontinuation of the Open-lab Treatment phase study drug and/or any AEs leading to premature discontinuation of Open-label Treatment phase study drug.

Percentage of Participants Who Experienced Laboratory Abnormalities
Assessment method [6] 0 0
Treatment-emergent laboratory abnormalities for Blinded Treatment phase are defined as values that increase at least 1 toxicity grade from baseline at any postbaseline time point, up to and including the date of last dose of Blinded Treatment phase study drug plus 30 days for participants who permanently discontinued Blinded Treatment phase study drug or before the first dose of Open-label Treatment phase study drug. For the Open-label Treatment phase, treatment-emergent laboratory abnormalities are defined as values that increase at least 1 toxicity grade from Open-label baseline at any postbaseline time point, up to and including the date of last dose of Open-label Treatment phase study drug plus 30 days for participants who permanently discontinued Open-label phase study drug. For maximum postbaseline toxicity grade, the most severe graded abnormality from all tests was counted for each patient. Grade 1: mild; Grade 2: moderate; Grade 3: severe; Grade 4: life-threatening.
