Amsterdam Molecular Therapeutics Provides Status Update on Glybera(R)

AMSTERDAM, May 10, 2011 /PRNewswire/ -- Amsterdam Molecular Therapeutics (Euronext: AMT), a leader in the field of human gene therapy, provided today a status update on Glybera (alipogene tiparvovec), its gene therapy product under development for the treatment of lipoprotein lipase deficiency (LPLD).

Following the submission of the Day 180 questions at the end of the first quarter to the European Medicines Agency (EMA) as part of Glybera's Market Authorisation Application (MAA), AMT continues to work diligently with the EMA and is confident that a decision on the approval of Glybera remains on track for mid-2011 as previously guided.

"Our interactions with the EMA continue to be positive and we are encouraged as we hit each milestone in the path towards a regulatory decision. If approved, Glybera would be the first gene therapy product to reach the market in Europe. We will continue to work with the EMA so that the review of our data remains on track as much as possible from our side and look forward to a decision in mid-2011," stated Jörn Aldag, CEO of AMT. "Our data are key to supporting our MAA. Later this month we will present additional data at ASGCT regarding improved chylomicron handling, which we believe could be used in the future by physicians as a biomarker for Glybera in LPLD patients."

AMT scientists and collaborators will present data from Glybera and several other gene therapy programs in a total of nine posters at the American Society of Gene and Cell Therapy (ASGCT) 14th Annual Meeting to be held in Seattle, USA, May 18-21. In particular, the company will provide an update on previously announced initial results from a long-term clinical study of Glybera that showed improved chylomicron metabolism could show utility as a biomarker in LPLD patients.

Several posters will report advances made by AMT in the field of RNAi delivery including additional data relating to Apoliprotein B silencing in hypercholesterolemia and delivery of miRNA molecules into the brain for development in Huntington's disease.

About Amsterdam Molecular Therapeutics

AMT is a world leader in the development of human gene based therapies. The company's lead product Glybera(R), a gene therapy for lipoprotein lipase deficiency (LPLD), is currently under review by the European Medicines Agency (EMA). If approved, Glybera will be the first gene therapy product to be marketed in Europe. AMT also has a product pipeline of several gene therapy products in development for hemophilia B, Duchenne muscular dystrophy, acute intermittent porphyria, and Parkinson's disease. Using adeno-associated viral (AAV) derived vectors as the delivery vehicle of choice for therapeutic genes, the company has been able to design and validate probably the world's first stable and scalable AAV manufacturing platform. This proprietary platform can be applied to a large number of rare (orphan) diseases caused by one faulty gene and allows AMT to pursue its strategy of focusing on this sector of the industry. AMT was founded in 1998 and is based in Amsterdam. Further information can be found at http://www.amtbiopharma.com.
