– Decision of European Patent Office Validates Significance of Exclusively Held Tuschl II Patent for RNAi Therapeutics –
CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), a leading RNAi therapeutics company, announced today that the European Patent Office (EPO) has fully upheld its Tuschl II ’044 (EP 1407044) patent in oral opposition proceedings held in Munich. Specifically, the originally granted claims of the ’044 patent were upheld without any modification and were deemed valid and supported by the EPO. Opponents included Sirna Therapeutics Inc., a subsidiary of Merck & Co., Silence Therapeutics AG, Pfizer Inc., BASF SE, and an anonymous party, who collectively failed in their arguments during the course of multi-day proceedings to revoke the patent.
“We are extremely pleased with the outcome of these opposition proceedings which resulted in the claims from the Tuschl II ’044 patent being fully upheld. This affirms our long-standing and resolute belief in the validity of these claims and the groundbreaking nature of the Tuschl II invention forming the basis of this critical patent family,” said Barry Greene, President and Chief Operating Officer of Alnylam. “Tuschl II remains a very important and valuable patent in our overall broad estate of patents important for the development and commercialization of RNAi therapeutics, and a patent family to which we are the exclusive licensee. We look forward to the continued advancement of the Tuschl II patent family worldwide in conjunction with many other Alnylam-held patents and pending patent applications.”
The Tuschl II patent series provides broad exclusivity for small interfering RNAs (siRNAs), the molecules that mediate RNAi, in the world’s top pharmaceutical markets, which include the U.S. (US 7,056,704 and US 7,078,196), the European Union (EP 1407044), China (CN100523215), and Japan (JP04095895 and JP04494392). Specifically, the European Tuschl II ’044 patent broadly covers compositions, methods, and uses of siRNAs that are important for the development and commercialization of RNAi therapeutics. The Tuschl II patent family is exclusively licensed to Alnylam for RNAi therapeutics on a worldwide basis through an agreement with Max Planck Innovation GmbH, the licensing agent for the Max Planck Society.

The Pool for Open Innovation against Neglected Tropical Diseases (NTD) was formed to aid in the discovery and development of new medicines for the treatment of 16 NTDs, as defined by the U.S. Food and Drug Administration, in the world’s least developed countries. BIO Ventures for Global Health (BVGH) is the administrator of patent pool, and in this role will organize disease-specific meetings that identify the gaps in expertise and intellectual property that currently exist in product development for NTDs, and will help global health researchers work with industry to fill these gaps to create medicines for NTDs faster and more efficiently.
About RNA Interference (RNAi)
RNAi (RNA interference) is a revolution in biology, representing a breakthrough in understanding how genes are turned on and off in cells, and a completely new approach to drug discovery and development. Its discovery has been heralded as “a major scientific breakthrough that happens once every decade or so,” and represents one of the most promising and rapidly advancing frontiers in biology and drug discovery today which was awarded the 2006 Nobel Prize for Physiology or Medicine. RNAi is a natural process of gene silencing that occurs in organisms ranging from plants to mammals. By harnessing the natural biological process of RNAi occurring in our cells, the creation of a major new class of medicines, known as RNAi therapeutics, is on the horizon. Small interfering RNAs (siRNAs), the molecules that mediate RNAi and comprise Alnylam’s RNAi therapeutic platform, target the cause of diseases by potently silencing specific mRNAs, thereby preventing disease-causing proteins from being made. RNAi therapeutics have the potential to treat disease and help patients in a fundamentally new way.
About Alnylam Pharmaceuticals
Alnylam is a biopharmaceutical company developing novel therapeutics based on RNA interference, or RNAi. The company is applying its therapeutic expertise in RNAi to address significant medical needs, many of which cannot effectively be addressed with small molecules or antibodies, the current major classes of drugs. Alnylam is leading the translation of RNAi as a new class of innovative medicines with peer-reviewed research efforts published in the world’s top scientific journals including Nature, Nature Medicine, and Cell. The company is leveraging these capabilities to build a broad pipeline of RNAi therapeutics for the treatment of a wide range of disease areas, including respiratory syncytial virus (RSV), liver cancers, TTR-mediated amyloidosis (ATTR), hypercholesterolemia, and Huntington’s disease. In addition, Alnylam formed Alnylam Biotherapeutics, a division of the company focused on the development of RNAi technologies for application in manufacturing processes for biotherapeutic products, including recombinant proteins and monoclonal antibodies. The company’s leadership position in fundamental patents, technology, and know-how relating to RNAi has enabled it to form major alliances with leading companies including Medtronic, Novartis, Biogen Idec, Roche, Takeda, Kyowa Hakko Kirin, and Cubist. Alnylam and Isis are majority owners of Regulus Therapeutics Inc., a company focused on the discovery, development, and commercialization of microRNA therapeutics. Founded in 2002, Alnylam maintains headquarters in Cambridge, Massachusetts. For more information, please visit www.alnylam.com.
