These diseases are associated with significant morbidity and mortality resulting in substantial costs to society, as about 6% to 8% of the total population in the Western world is affected by one of the circa 8,000 different orphan diseases that have been identified to date. About 80% of these identified orphan diseases are genetic disorders. By inserting the correct gene in the relevant tissues, our gene therapy products offer a long-term cure of the respective disease, whereas existing treatments only treat symptoms and subsequent medical complications. AMT's product pipeline currently consists of six products in different stages of development. Its lead product, AMT-011 to treat LPL deficiency, a very serious and rare metabolic disease, is currently in pre-registration clinical trials. For this product AMT expects to file in Europe for market authorization in the first quarter of 2008, followed by a filing in the US and Canada. All of the products in AMT's pipeline are based on its AAV (Adeno Associated Virus)-based gene insertion technology platform and its baculovirus based manufacturing platform. AMT is focusing on AAV, because of its proven safety. AMT genetically engineers AAV vectors to target various organs or specific tissues, such as muscle or liver, and even specific types of cells within these organs. By combining its AAV-based vectors with different therapeutic genes and tissue specific promoters, AMT has a platform vector technology that is modular in approach and this can facilitate fast product design timelines for its future products. AMT's competitive strengths and attributes are as follows: Delivery of a single-dose long-term cure for serious and rare diseases (orphan diseases); Modular platform that can be applied to a large number of diseases; Potential to shorten time-to-market because of R&D capabilities and processes as well as its orphan drug focus; Collaborations with leading academic research groups fueling our future product pipeline; and A proven ability to upscale the manufacturing of our lead products. The company's Management, Supervisory Board and Scientific Advisory Board bring together an extensive know-how of genetics and the biotech and pharmaceutical industries. The company was founded in 1998 by scientists of the University of Amsterdam Medical Center (AMC). Use of proceeds AMT intends to use the proceeds of the IPO primarily for the development and commercialization of its products and to build a specialized marketing and sales team for Europe and North America capable of selling its lead product AMT-011 for LPL deficiency.
