Genzyme Receives Positive Opinion on Myozyme from CHMP



CAMBRIDGE, Mass.--(BUSINESS WIRE)--Genzyme Corporation (Nasdaq: GENZ) announced today that the Committee for Medicinal Products for Human Use (CHMP) has issued a positive opinion on the company’s variation to produce Myozyme® (alglucosidase alfa) at the 4000 liter (L) bioreactor scale at its manufacturing facility in Geel, Belgium. The positive CHMP opinion is the final step before formal approval to produce and market Myozyme manufactured at the 4000 L bioreactor scale in the European Union, Norway and Iceland.

The CHMP acted quickly on the application due to the current constraints on supply. The 4000 L manufacturing process is expected to help provide adequate supply of Myozyme in Europe for the foreseeable future.

The committee's opinion will be forwarded to the European Commission, which will make a final decision on the authorization. The Commission has 44 calendar days to act on the CHMP’s opinion. The European Commission generally follows the advice of the CHMP, but it is not obliged to do so.

About Myozyme

Myozyme is the only approved treatment for Pompe disease, a progressively debilitating disease that manifests as a broad spectrum of clinical symptoms. All patients typically experience progressive muscle weakness and breathing difficulty, but the rate of disease progression can vary widely depending on the age of onset and the extent of organ involvement. When symptoms appear within a few months of birth, babies frequently display a markedly enlarged heart and die within the first year of life. When symptoms appear during childhood, adolescence or adulthood, patients may experience steadily progressive debilitation and premature mortality due to respiratory failure. They often require mechanical ventilation to assist with breathing and wheelchairs to assist with mobility.
