HAWTHORNE, N.Y.--(BUSINESS WIRE)--Oct. 16, 2007--Researchers at Mayo Clinic have presented details from a preclinical study showing that a recombinant human monoclonal antibody, administered in a single low dose in a laboratory mouse model of multiple sclerosis, can repair myelin, the insulating covering over nerve fibers in the central nervous system.
The study was presented on October 9, 2007 at the American Neurological Association meeting in Washington, D.C.
"We are excited to be collaborating with Mayo on the development of this therapy," noted Andrew R. Blight, Ph.D., Chief Scientific Officer at Acorda. "The options for treatment of MS are still quite limited, and a new approach that could repair damage to the central nervous system would represent an important advance for the individuals who live with this disease."
In multiple sclerosis and some other disorders of the central nervous system, the immune system attacks and destroys the myelin sheath, causing the nerve to lose its ability to conduct electrical impulses from the brain to the body, resulting in the disabilities associated with those conditions.
The antibody, which was genetically engineered for large-scale production, binds to myelin and the surface of cells in the brain and spinal cord, triggering the cells to begin the repair process called remyelination. The study was conducted using a laboratory mouse model of chronic progressive multiple sclerosis in humans. The antibody was delivered alone and in combination with the steroid methylprednisolone; remyelination was detected in both instances.
The antibody is being developed by Mayo Clinic and Acorda Therapeutics. Under a license agreement between Acorda and Mayo Clinic, Acorda holds exclusive worldwide rights to certain patents and other intellectual property for this antibody related to use and treatment of central nervous system disorders, including multiple sclerosis. Both Acorda and Mayo will be working on the steps leading to a future Investigational New Drug Application (IND) and a Phase 1 clinical trial.
About Multiple Sclerosis
Multiple sclerosis is a chronic, usually progressive disease of the central nervous system in which the immune system attacks and destroys the structure, and therefore degrades the function, of nerve cells. According to the National Multiple Sclerosis Society, approximately 400,000 Americans have MS, and every week about 200 people are newly diagnosed. Most are between the ages of 20 and 50, and women are affected two to three times as much as men. Worldwide, MS may affect 2.5 million individuals.
The NMSS estimates the direct costs of medical care for MS patients in the United States to exceed $6 billion annually. Additionally, a recent NMSS analysis estimated the total cost of MS, including medical and non-medical care, production losses, and informal care, at more than $47,000 per U.S. patient per year. Complications from MS may make it harder for people to work and may interfere with their ability to perform common, daily activities.
For most people with MS, the disease slowly progresses with a series of unpredictable flare-ups, also called relapses or exacerbations. But for some, the progression of the disease is rapid. Each relapse tends to lead to increasing disabilities such as walking impairment, muscle weakness or speech or vision impairments.
