For US sites only, subjects must also provide an authorization to use protected health information (in accordance with the Health Insurance Portability and Accountability Act or HIPAA in the US)

E.4 | Principal exclusion criteria |
Subjects will be ineligible for this study if they meet any one of the following criteria: 1) UC requiring immediate surgical, endoscopic, or radiologic interventions, including massive hemorrhage, perforation and sepsis, suppurative complications (intra-abdominal or perianal abscesses), or toxic megacolon requiring imminent intervention 2) White blood cell count less than 2.5 x 103/mcL; platelet count less than 150 x 103/mcL; or hemoglobin level less than 8 g/dL 3) Active medically significant infections, particularly those of viral etiology, eg, known CMV colitis. This includes any incidence of medically significant, opportunistic infections (see Definitions) within the past 12 months 4) Live vaccination within 6 weeks prior to randomization. (Subjects may not receive a live vaccine during dosing or for 60 days after receiving the last dose of study drug) 5) History of deep vein thrombophlebitis or pulmonary embolus 6) Significant organ dysfunction, including cardiac, renal, liver, CNS, pulmonary, vascular, gastrointestinal, endocrine, or laboratory abnormality (eg, creatinine ≥1.6 mg/dL; ALT or AST ≥1.5X the upper limit of normal [ULN]; alkaline phosphatase ≥1.5X ULN); history of myocardial infarction, coronary artery disease, congestive heart failure, or arrhythmias within 6 months prior to consent 7) History of lymphoproliferative disorder (LPD) or malignancy other than nonmelanoma skin cancer or carcinoma in situ of the cervix that has been adequately treated 8) Seropositive for infection with human immunodeficiency virus (HIV-1), hepatitis B virus (HBV) surface antigen, or hepatitis C virus (HCV) 9) Pregnant women or nursing mothers 10) Treatment with any other UC salvage drugs (including but not limited to infliximab, cyclosporine, tacrolimus [FK506], adalimumab, thalidomide, or another experimental agent), or therapies (surgery, pheresis, affinity columns) since the first course of treatment with study drug in the parent visilizumab study 11) Treatment with any other investigational drug or therapy within 60 days prior to randomization 12) Nontherapeutic levels of chronic antiseizure medications in subjects with a history of seizures, as tested within 4 days prior to randomization 13) Any condition that, in the investigator’s opinion, makes the subject unsuitable for study participation

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is the comparison of the proportion of subjects who respond to retreatment on Day 45 (± 4days) in the visilizumab and placebo groups for the first retreatment course. A subject is defined as a retreatment responder if he/she has a ≥ 3-point (or ≥30%) reduction in the Mayo score from baseline, with the rectal bleeding subscore reduced by at least 1 point, or an actual rectal bleeding subscore of 0 to 1.
