Inclusion criteria
Inclusion criteria: 1. Subject who is capable of understanding and complying with protocol requirements in the opinion of the investigator. 2. Subject who signs and dates a written informed consent form prior to the initiation of any study procedures. 3. Subjects who have had a diagnosis of moderate to severe UC for at least 3 months prior to enrollment. 4. Subjects with complete Mayo score of 6 to 12 and endoscopic subscore of>=2 within 10 days before the initial administration of vedolizumab. 5. Subjects who met the following treatment failure criteria with at least one of the following agents: Corticosteroids Resistance subjects whose response was inadequate after treatment of>=40 mg day for>=1 week (oral or intravenous IV) or 30 to 40 mg day for>=2 weeks (oral or IV) or topical therapy for >=2 weeks in case of distal UC. Dependence subjects for which it was difficult to reduce the dosage to =12 weeks.
