Study Summary
This study will examine the safety and effectiveness of Zenapax (a laboratory-manufactured antibody) in treating multiple sclerosis. Multiple sclerosis may be caused by an abnormal immune response in which white blood cells called T lymphocytes attack the myelin sheath that covers nerves and parts of the spinal cord. Zenapax binds to protein receptors on lymphocytes, keeping them from interacting with interleukin-2, a substance necessary for their growth. Patients with multiple sclerosis who have had at least one relapse within 18 months of the start of the study and in whom interferon-beta treatment has not been successful may be considered for this study. There are two study phases: baseline and treatment. During the baseline phase, patients will have three magnetic resonance imaging (MRI) scans over 2 months to evaluate their disease activity. During treatment, patients will receive seven intravenous (I.V.) infusions of Zenapax in the clinic. The first two infusions will be given 2 weeks apart; the next five will be given once a month. Patients will have MRI scans before each infusion. The MRIs will be done using the standard procedure and again using a contrast agent, gadolinium, injected into a vein. Gadolinium helps identify new multiple sclerosis lesions in the brain. Blood and urine samples will be taken during each clinic visit. In addition, patients will have skin tests, similar to a tuberculin test, to evaluate immune status, and will be asked to undergo two lumbar punctures (spinal tap; these will be optional)-one before the treatment phase begins, and another when treatment is completed. Lymphocytes will also be collected from patients before, during and after treatment. The lymphocytes are obtained by a procedure called apheresis: about a pint of whole blood is drawn through a needle in the arm, the lymphocytes are separated out and removed by a machine, and the rest of the blood is returned through a needle in the other arm. These studies will hopef
