1)Males and females, 18 years of age or older. 2)Only 1 prior treatment course with visilizumab (or placebo in a blinded visilizumab study). 3)Response (as defined in parent protocol) of IVSR-UC disease to visilizumab or placebo. 4)Active disease at screening, and symptomatic worsening, defined as an increase of >=3 points from the subject's best MTWSI response, and a score of >=9, sustained for at least 2 assessments, performed at least 1 week apart; and a confirmatory MTWSI >=8 within 1 day prior to randomization. 5)CD3+4+ T-cell count >=200 cells/mcL at screening for this protocol, or >=80% of the subject's screening baseline count prior to enrollment on the parent study. 6)Mayo assessment (including flexible sigmoidoscopy) performed by a trained, blinded evaluating physician within 2 weeks prior to randomization. 7)Adequate contraception from the day of consent through 3 months after the last dose of study drug. 8)Negative serum pregnancy test at screening. 9)Negative Clostridium difficile test within 10 days prior to randomization. 10)Signed and dated informed consent, and HIPAA if applicable.

- Primary Outcome Measures
Name Time Method Main Objective: To compare the efficacy, safety, pharmacokinetics, and immunogenicity in subjects retreated with visilizumab or placebo after a response in a prior visilizumab study.;Secondary Objective: na;Primary end point(s): The comparison of the proportion of subjects retreated with visilizumab versus placebo that respond on Day 45 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.
