- Clinical Response at Week 12 [ Time Frame: Week 12 ]Clinical response as defined by Mayo score. The Mayo score is 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.
- Clinical Remission at Week 12 [ Time Frame: Week 12 ]Clinical remission as defined by Mayo score. The Mayo score is 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.
