( KANSAS CITY Mo.--(BUSINESS WIRE)--May ...)Treatment with Copaxone Plus Minocycline Showed Substantial,Reduction of Disease Activity in Patients with Active,Relapsing-Remitting Multiple Sclerosis,Health

KANSAS CITY, Mo.--(BUSINESS WIRE)--May 4, 2007 - New data from a randomized, double-blind study showed that a combination of COPAXONE(R) (glatiramer acetate injection) along with the oral antibiotic minocycline reduced T1 Gadolinium (Gd)-enhancing lesions of the brain by 63 percent (p=0.08) in patients with active relapsing-remitting multiple sclerosis (RRMS), as measured by magnetic resonance imaging (MRI), compared to those receiving COPAXONE(R) alone. Additionally, the nine-month study demonstrated that treatment with COPAXONE(R) in combination with minocycline reduced the number of new T2 lesions in patients by 65 percent (p=0.06). These results trended toward but did not reach statistical significance.

These data were presented at the 59th Annual Meeting of the American Academy of Neurology (AAN) in Boston, MA, April 28 - May 5, 2007.

"The results of this study indicated that further exploration of this combination is warranted, as the established effect of COPAXONE(R) on disease activity may be boosted when used in combination with minocycline for the treatment of active relapsing-remitting patients," said Luanne Metz, M.D., professor at the Department of Clinical Neuroscience of the University of Calgary, and principal investigator. "In these patients, the combination was safe and well tolerated," she added.

Minocycline is a broad-spectrum antibiotic, which is used to treat pneumonia, acne, and infections of the skin, genital and urinary systems, and the central nervous system. In a small proof-of-concept trial of 10 RRMS patients, minocycline demonstrated an 84 percent relative reduction in mean total Gd-enhancing lesions and was well tolerated, and data published in the Journal of Neuroimmunology indicated that the combination of minocycline and COPAXONE(R) decreased neuron-inflammation, axonal loss and demyelination in an animal model of MS.
