Filter by:OBJECTIVES: I. Evaluate the safety and immunogenicity of single and multiple doses of M-T412, a chimeric murine-human anti-CD4 monoclonal antibody, in patients with multiple sclerosis. II. Evaluate the pharmacokinetics of M-T412. III. Obtain preliminary data on the clinical response to M-T412.
OBJECTIVES: I. Compare tolerance to and therapeutic impact of copolymer 1, a mixture of synthetic polypeptides, with placebo in patients with relapsing-remitting multiple sclerosis.
OBJECTIVES: I. Determine whether high-dose intravenous immune globulin (IVIG) is more effective than placebo in restoring neurologic function (muscle strength) in patients with multiple sclerosis. II. Determine the time to recovery following IVIG.
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 hopefully allow conclusions about the safety of Zenapax in MS, but also address its effectiveness with respect to modifying the inflammatory activity in the brain of MS patients and inhibit autoimmune T lymphocytes that are involved in the disease process.
Multiple sclerosis (MS) is a disease of the nervous system. The exact cause of MS is unknown, but it is believed to be an autoimmune condition. Autoimmune conditions are diseases that cause the body's immune system and natural defenses to attack healthy cells. In the case of MS, the immune system begins attacking myelin, the cells that make up the sheath covering nerves. Without myelin nerves are unable to transmit signals effectively and symptoms occur. Researchers are interested in testing the safety, tolerability, and effectiveness of a new therapy (CGP77116) for Multiple Sclerosis (MS). CGP77116 is a small protein similar to the protein in myelin. CGP77116 is designed to modify the immune reaction that destroys normal myelin. CGP77116 is an experimental therapy meaning it has not been approved by the U.S. Food and Drug Administration. However, in preliminary studies on animal it has been shown to be effective at modifying the autoimmune reaction associated with the development of MS. The purpose of this study is to assess the safety and effect of CGP77116 on disease activity in patients with Multiple Sclerosis as measured by magnetic resonance imaging (MRI) and immunological studies. The study is broken into three parts: I) BASELINE: in the first part of the study patients will undergo 6 MRIs over a 5 month period. During this time, patients will be evaluated based on the presence of MS lesions seen on MRI. Patients whose MS lesions are highly active will be entered into the second part of the study. II) TREATMENT: in the second part of the study, patients with active MS lesions will begin receiving CGP77116. The drug will be given by injection once a week for one month and then once a month for 8 additional months. III) FOLLOW-UP: in the third and final part of the study, patients will undergo an MRI every 2 months for 6 months and then every 3 months for 6 additional months. The results of the MRIs will be used to measure the effectiveness of CGP77116.
The drug rhIGF-1 (CEP-151) has been shown to play a key role preclinically in oligodendrocyte differentiation and survival, as well as, myelin integrity and function. Moreover, in an animal model of MS, myelin expression, as well as that of its receptors is upregulated at the time the myelin sheaths regenerate. Finally, administration of exogenous rhIGF-1 to rats with EAE effectively, closes the disrupted BBB, reduces the number and severity of demyelinating lesions, and improves neurological function. Thus it seems reasonable to examine the efficacy and safety, tolerability, and effect of CEP-151 on brain MRI lesions in patients with MS.

This study is directed toward a better understanding of the cause of Multiple Sclerosis (MS). Researchers will evaluate patients with a tentative diagnosis of MS or other neurological diseases possibly caused by a immunological reaction. Patients will undergo a series of three MRIs, taken once a month for three months and submit blood samples for immunological studies.
