Cambridge Laboratories Limited’s XENAZINE® 25 Mg Launched In France

25 August 2006 – Cambridge Laboratories, the specialist pharmaceuticals company, today announces that its partner, OPi SA, has launched XENAZINE® 25mg (tetrabenazine) in France, following publication in the “Journal Officiel” of its reimbursement price that has been granted by the authorities. The product has been approved for use in the treatment of movement disorders associated with Huntington’s disease, and in the treatment of hemiballismus.

XENAZINE® 25mg is a neuroleptic-like agent that was exclusively licensed by Cambridge Laboratories to OPi in 2003 for commercialisation in France. The product received marketing approval for France in late 2005.

Mark Evans, Cambridge Laboratories CEO, said: “XENAZINE® has been prescribed by French neurologists for many years for the treatment of hyperkinetic movement disorders and we are delighted that it is now freely available under reimbursement by Social Security in France through our partner, OPi, for patients suffering with the debilitating effects of chorea associated with Huntington’s disease and hemiballismus.”

“In France, approximately 6,000 patients suffer from Huntington’s disease, a severe and debilitating neurodegenerative disease. XENAZINE® 25 mg is the first product approved in France for use in this indication and as such, the full availability of this product is a great progress for these patients,” commented Dr.Gilles Alberici, President and Founder of OPi SA.

About XENAZINE®

XENAZINE® is a highly selective and reversible dopamine depletor that works by inhibiting vesicular monoamine transporter 2 (VMAT2). XENAZINE® is the first product for which an NDA has been filed in the U.S. for treatment of chorea associated with Huntington’s disease. Chorea, a debilitating feature of a number of neurological diseases, is characterized by excessive, involuntary, and repetitive movements, which may involve the face, limbs, or the entire body. In HD, it is the result of overactivity of the neurotransmitter dopamine.
