Inclusion Criteria

1) Signed written informed consent 2) Subject must have had ulcerative colitis (UC) for at least 3 months from the time of initial diagnosis.The diagnosis of UC must have been confirmed by endoscopic and histologic evidence.If no previous confirmation of diagnosis is available or if previous diagnosis is not deemed conclusive, at time of screening endoscopy, histology should be performed to confirm diagnosis of UC 3) Subjects must satisfy one of the following criteria: a) In the past, had an inadequate response to one or more of the following treatments: i) Oral aminosalicylates (e.g.mesalamine, sulfasalazine, olsalazine, balsalizide) at or above the approved label dose for at least 6 weeks, and/or ii) Prednisone >= 40 mg/day (or equivalent) for at least 2 weeks, and/or iii) Immunosuppressants [azathioprine >= 2 mg/kg/day or 6-mercaptopurine >= 1.0 mg/kg/day, (or documentation of a therapeutic concentration of 6-thioguanine nucleotide)] for at least 12 weeks, and/or iv) An approved anti-TNF agent at an approved labeled dose for at least 8 weeks and/or v) Intravenous hydrocortisone >= 400 mg/day (or equivalent) for at least 1 week. AND/OR b) had been intolerant to one or more of the above mentioned treatments [e.g, unableto achieve doses or treatment durations because of dose limiting side effects (e.g.leukopenia, psychosis, uncontrolled diabetes, elevated liver enzymes)] AND/OR c) Currently receiving one or more of the following treatments: i) Oral aminosalicylates (e.g.mesalamine, sulfasalazine, olsalazine, balsalizide) at or above the approved label dose for at least 6 weeks and/or ii) Prednisone >= 20 mg/day (or equivalent) for at least 4 weeks and/or iii) Immunosuppressants [azathioprine >= 2 mg/kg/day or 6-mercaptopurine >= 1.0 mg/kg/day, (or documentation of a therapeutic concentration of 6-thioguanine nucleotide)] for at least 12 weeks. Subjects currently receiving oral corticosteroids, oral aminosalicylates, azathioprine, or 6-mercaptopurine should continue their treatment (see Protocol Section 6.4.2.1).Subjects who had an inadequate response and/or intolerance to anti-TNF treatment must have had their last dose at least 8 weeks prior to the entry into the Induction Period.Subjects who had an inadequate response and/or intolerance to intravenous corticosteroid treatment must have had their last dose at least 4 weeks prior to entry into the Induction Period. Inadequate response and/or intolerance in the past (as defined above) will be assessed by the treating physician. Acceptable documentation of inadequate response or intolerance in subjects include one or more of the following: medical records; letters provided by the referring physician; other referral documents (e.g., insurance authorization forms), provided they contain the relevant information to support the subject's ?inadequate response' and/or ?intolerance' to the designated therapy. In all circumstances, it should be established that discontinuation of the designated treatments was primarily due to lack of efficacy or intolerance (e.g., not due to unavailability of the drug). Subjects in clinical remission should not discontinue UC therapy that is maintaining clinical remission, for the purpose of meeting eligibility requirements to enroll into this study. 4) Subjects must have a Mayo score >= 6 and an endoscopic subscore of >= 2 5) Oral corticosteroid treatment must have been the equivalent of =< 30 mg prednisone daily at a stab
