BioMarin Pharmaceutical Inc. Establishes Commercial Operations In Europe

NOVATO, Calif., and LONDON, Jan. 10 /PRNewswire-FirstCall/ -- BioMarin Pharmaceutical Inc. announced today that it has established commercial operations in Europe in anticipation of receiving European marketing approval for Naglazyme(TM) (galsulfase), an enzyme replacement therapy for the treatment of mucopolysaccharidosis VI (MPS VI; Maroteaux-Lamy syndrome), in the first quarter of 2006. BioMarin Europe Ltd. is headquartered in London, with branch offices located in Spain, Switzerland and Italy.

William E. Aliski has been appointed Vice President and General Manager of European Operations, responsible for overseeing European commercialization efforts. Prior to joining BioMarin, Mr. Aliski served as Vice President of Commercial Operations at Transkaryotic Therapies, a biotechnology company that, prior to its acquisition by Shire Pharmaceuticals Group in July 2005, focused on the development and commercialization of products to treat rare diseases. In this role, Mr. Aliski managed worldwide drug distribution, inventory management and patient support for the company's lead product, Replagal, an enzyme replacement therapy for Fabry disease. Earlier in his career, Mr. Aliski worked at Genzyme Corporation, a biopharmaceutical company focused on serious diseases, including genetic disorders, where he served as Vice President of Health Systems and Vice President of Patient and Product Services, responsible for overseeing the development and implementation of reimbursement planning and launch for multiple products, including Cerezyme and Ceredase.

"We are pleased that Mr. Aliski has joined the BioMarin team and believe that his experience in the global commercialization of products for rare diseases further positions us for a successful European commercial launch of Naglazyme for MPS VI, pending final regulatory approval," stated Steve Aselage, Senior Vice President of Global Commercial Operations of BioMarin. "With BioMarin Europe now in place, we look forward to commencing our first European product launch and to making Naglazyme available to the European MPS VI community in the not too distant future."

BioMarin Europe, an Irish subsidiary, will be responsible for overseeing the sales and distribution of Naglazyme to the 25 member states of the European Union, Iceland and Norway. Those wishing to correspond with BioMarin Europe should contact:
