Research Study in Patients With Severe Ulcerative Colitis

A Phase I, Dose-Escalation, Pilot Study of Visilizumab in Patients With Severe Ulcerative Colitis That is Refractory to Corticosteroids

The purpose of the study is to evaluate an intravenous (by injection) investigational medication to treat severe ulcerative colitis refractory to steroid therapy. The research is being conducted at up to 8 clinical research sites in the US and is open to both men and women ages 18 to 70 years old. Participants in the study will have a number of visits to a research site. All study-related care and medication is provided to qualified participants at no cost: this includes all visits, examinations and laboratory work.

A Phase I, dose-escalation, pilot study designed to obtain safety and tolerability data on visilizumab administered to patients with severe ulcerative colitis that has failed to respond to steroid therapy. Patients who are currently receiving IV corticosteroids, but whose disease has not responded after at least 5 days of this therapy, will be eligible for the study.

1. A diagnosis of ulcerative colitis verified by colonoscopy or barium enema performed within 36 months prior to study entry.
2. Active disease despite ongoing treatment with steroids
