This is a prospective, single country, multi-center study in participants with ulcerative colitis (UC) treated with adalimumab. Up to 147 participants are enrolled at approximately 20 sites. The baseline assessment is performed prior to the first dose of adalimumab (Visit 1). Study visits are conducted at weeks 8, 16, 24, 32, 40, 48 and 56 after baseline in accordance with clinical practice. All participants will have one Follow-up for safety approximately 70 days after the last dose of adalimumab.
This is a prospective, single-country, multi-center study in UC patients treated with adalimumab. The prescription of adalimumab is at the discretion of the physician in accordance with clinical practice and label, is made independently from this study, and preceded the decision to offer the patient the opportunity to participate in this study. Up to 147 subjects are planned to be enrolled at approximately 20 sites. The baseline assessment is performed prior to the first dose of adalimumab (Visit 1). Participants are administered adalimumab 160 mg at Week 0, 80 mg at Week 2, and then 40 mg every other week per the Korean label. Study visits are conducted at Weeks 8, 16, 24, 32, 40, 48 and 56 after baseline in accordance with clinical practice. All participants had one Follow-up for safety approximately 70 days after the last dose of adalimumab. Clinical response is assessed at Week 8, and participants with clinical response at Week 8 can continue on adalimumab treatment as per Korean reimbursement guidelines. Clinical response is defined as a decrease from baseline in the total Mayo score by at least 3 points and at least 30% with an accompanying decrease in rectal bleeding subscore of at least 1 point or absolute rectal bleeding sub-score of 0 or 1.

Percentage of Participants Who Were Week 8 Responders With Durable Clinical Response at Week 56
Durable clinical response was defined as reduction in complete Full Mayo score of ≥3 points and ≥30% from Baseline (Week 0) with an accompanying decrease in rectal bleeding subscore of ≥1 point or absolute rectal bleeding subscore of ≤1 point at both Week 8 and 56. Clinical response was defined as reduction in complete full Mayo score of ≥3 points and ≥30% from Baseline (Week 0) with decrease in rectal bleeding subscore of ≥1 point or absolute rectal bleeding subscore of ≤1 point at Week 8. The Mayo score is a tool designed to measure disease activity for ulcerative colitis. The Mayo score ranges from 0 (normal or inactive disease) to 12 (severe disease) and is calculated as the sum of 3 subscores (stool frequency, rectal bleeding, endoscopy, and physician's global assessment \[PGA\]), each of which ranges from 0 (normal) to 3 (severe disease). A negative change in Mayo score indicates improvement.
