CAMBRIDGE, Mass.--([ BUSINESS WIRE ])--Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), a leading RNAi therapeutics company, announced today that it has submitted an investigational new drug (IND) application to the U.S. Food and Drug Administration (FDA) for ALN-VSP, an RNAi therapeutic for the treatment of liver cancers, including hepatocellular carcinoma and other solid tumors with liver involvement. ALN-VSP contains two small interfering RNAs (siRNAs), the molecules that mediate RNAi, formulated in a lipid nanoparticle developed by Tekmira Pharmaceuticals Corporation. ALN-VSP is designed to target two genes critical in the growth and development of cancer: kinesin spindle protein, or KSP, required for tumor proliferation; and vascular endothelial growth factor, or VEGF, required for tumor growth. Pre-clinical data in mouse tumor model studies have demonstrated robust efficacy of ALN-VSP, including suppression of these targeted genes, demonstration of an RNAi mechanism of action, tumor reduction, and extension of survival.

"ALN-VSP represents Alnylam's first IND for a systemically delivered RNAi therapeutic, which is a testament to the very strong progress we've made in achieving systemic delivery of siRNAs, including our efforts with Tekmira," said Akshay Vaishnaw, M.D., Ph.D., Senior Vice President, Clinical Research at Alnylam. "We're also pleased, with this IND filing, to have met one of our key pipeline goals for 2008. Following FDA review of our submission, we expect to initiate patient dosing in the first half of 2009, which positions us solidly on track to meet our goal of having three programs in clinical trials next year."

"Based on the encouraging pre-clinical data we've seen to date with this program, we believe our strategy of using an RNAi therapeutic targeting two well-validated genes critical for tumor proliferation and survival has the potential of achieving meaningful clinical benefit for patients with liver cancer," said Dinah Sah, Ph.D., Vice President, Research, CNS and Oncology, at Alnylam. "We believe that this is the first dual targeting RNAi therapeutic program to advance to this stage of development across the entire industry. This is an important milestone, as we view the ability to design and formulate siRNAs that achieve dual targeting as a very attractive feature of our RNAi therapeutics platform, especially in the setting of oncology drug discovery."

"Cancer affecting the liver, either as primary disease or as metastatic spread from cancer originating at another site, represents a major cause of death and a major unmet medical need affecting a large number of patients in the U.S. and across the world," said George D. Demetri, M.D., director of the Ludwig Center at Dana-Farber Cancer Institute and Harvard Medical School, a collaborating investigator in this work. "Many common cancers, such as breast cancer and colorectal cancer, spread to the liver, where the metastatic disease is life threatening. Additionally, primary liver cancer, known as hepatocellular carcinoma, is one of the most common solid tumors in the world overall, and is associated with one of the poorest survival rates in cancer. The ALN-VSP clinical development program will have great impact in this area, if the pre-clinical testing can be translated into similar benefits for patients with liver involvement from cancer."

The proposed Phase I study is a multi-center, open label, dose escalation trial to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of intravenous ALN-VSP in patients with advanced solid tumors with liver involvement. Additional study design details will be provided upon initiation of the Phase I trial.

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. RNAi therapeutics target the cause of diseases by potently silencing specific messenger RNAs (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; its most advanced program is in Phase II human clinical trials for the treatment of respiratory syncytial virus (RSV) infection. In addition, the company is developing RNAi therapeutics for the treatment of a wide range of disease areas, including liver cancers, hypercholesterolemia, Huntington's disease, and TTR amyloidosis. 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, and Kyowa Hakko. To reflect its outlook for key scientific, clinical, and business initiatives, Alnylam established "RNAi 2010" in January 2008 which includes the company's plan to significantly expand the scope of delivery solutions for RNAi therapeutics, have four or more programs in clinical development, and to form four or more new major business collaborations, all by the end of 2010. Alnylam is a joint owner of Regulus Therapeutics LLC, a joint venture focused on the discovery, development, and commercialization of microRNA therapeutics. Founded in 2002, Alnylam maintains headquarters in Cambridge, Massachusetts. For more information, please visit http://[ www.alnylam.com ].
