Alnylam Pharmaceuticals, Inc. (Nasdaq:ALNY), a leading RNAi therapeutics company, announced today that the European Patent Office (EPO) has upheld the McSwiggen EP 1423406 (’406) patent in oral opposition proceedings in Munich, Germany. The McSwiggen patent estate broadly describes chemical modifications of RNAi therapeutics that the company believes are critical for achieving “drug-like” properties in siRNA, the molecules that mediate RNAi. The patent is owned by Alnylam, and was recently obtained through the company’s acquisition of Sirna Therapeutics from Merck. The McSwiggen patent family comprises a core component of Alnylam’s overall intellectual property (IP) estate for the advancement of RNAi therapeutics as a new class of medicines. “We are pleased with the European Patent Office’s decision to uphold the ’406 patent from our McSwiggen patent family, a key component of the IP estate we recently obtained through our acquisition of Sirna Therapeutics from Merck. This patent has broad and significant claims describing chemical modifications of RNAi therapeutics, which we believe are critical for the development and commercialization of all RNAi therapeutics,” said Laurence Reid, Ph.D., Senior Vice President and Chief Business Officer of Alnylam. “Our IP estate remains a cornerstone in our efforts to advance RNAi therapeutics to patients in need.” The McSwiggen patent family includes 21 granted or issued patents around the world, including patents in the U.S. (7,923,547; 7,956,176; 7,989,612; 8,202,979; 8,232,383; 8,236,944; 8,242,257; 8,268,986; 8,273,866) and the EU (1423406; 1458741; 1627061; 2278004; 2287306), and generally describes the chemical modification of siRNA. The claims for the McSwiggen ’406 patent cover compositions for siRNA, including, in general terms, a chemically modified double-stranded RNA that down regulates expression of a target gene by RNAi, wherein:
- each strand is independently 18 to 24 nucleotides in length and each duplex comprises 17 to 23 base pairs; and
- 10 or more pyrimidine nucleotides of the sense and/or antisense strand are chemically modified with 2'-deoxy, 2'-OMe, or 2'F with one or more phosphorothioate and/or a terminal cap at the 5', 3' or both, present in the same or different strand.
About Alnylam PharmaceuticalsAlnylam is a biopharmaceutical company developing novel therapeutics based on RNA interference, or RNAi. The company is leading the translation of RNAi as a new class of innovative medicines with a core focus on RNAi therapeutics as genetic medicines, including programs as part of the company’s “Alnylam 5x15 TM” product strategy. Alnylam’s genetic medicine programs are RNAi therapeutics directed toward genetically defined targets for the treatment of serious, life-threatening diseases with limited treatment options for patients and their caregivers. These include: patisiran (ALN-TTR02), an intravenously delivered RNAi therapeutic targeting transthyretin (TTR) for the treatment of TTR-mediated amyloidosis (ATTR) in patients with familial amyloidotic polyneuropathy (FAP); ALN-TTRsc, a subcutaneously delivered RNAi therapeutic targeting TTR for the treatment of ATTR in patients with TTR cardiac amyloidosis, including familial amyloidotic cardiomyopathy (FAC) and senile systemic amyloidosis (SSA); ALN-AT3, an RNAi therapeutic targeting antithrombin (AT) for the treatment of hemophilia and rare bleeding disorders (RBD); ALN-CC5, an RNAi therapeutic targeting complement component C5 for the treatment of complement-mediated diseases; ALN-AS1, an RNAi therapeutic targeting aminolevulinate synthase-1 (ALAS-1) for the treatment of hepatic porphyrias including acute intermittent porphyria (AIP); ALN-PCS, an RNAi therapeutic targeting PCSK9 for the treatment of hypercholesterolemia; ALN-AAT, an RNAi therapeutic targeting alpha-1-antitrypsin (AAT) for the treatment of AAT deficiency liver disease; ALN-TMP, an RNAi therapeutic targeting TMPRSS6 for the treatment of beta-thalassemia and iron-overload disorders; ALN-ANG, an RNAi therapeutic targeting angiopoietin-like 3 (ANGPTL3) for the treatment of genetic forms of mixed hyperlipidemia and severe hypertriglyceridemia; and other programs yet to be disclosed. As part of its “Alnylam 5x15” strategy, as updated in early 2014, the company expects to have six to seven genetic medicine product candidates in clinical development - including at least two programs in Phase 3 and five to six programs with human proof of concept - by the end of 2015. The company’s demonstrated commitment to RNAi therapeutics has enabled it to form major alliances with leading companies including Merck, Medtronic, Novartis, Biogen Idec, Roche, Takeda, Kyowa Hakko Kirin, Cubist, GlaxoSmithKline, Ascletis, Monsanto, The Medicines Company, and Genzyme, a Sanofi company. In March 2014, Alnylam acquired Sirna Therapeutics, a wholly owned subsidiary of Merck. In addition, Alnylam holds an equity position in Regulus Therapeutics Inc., a company focused on discovery, development, and commercialization of microRNA therapeutics. Alnylam scientists and collaborators have published their research on RNAi therapeutics in over 200 peer-reviewed papers, including many in the world’s top scientific journals such as Nature, Nature Medicine, Nature Biotechnology, Cell, the New England Journal of Medicine, and The Lancet. Founded in 2002, Alnylam maintains headquarters in Cambridge, Massachusetts. For more information, please visit www.alnylam.com.
