Dicerna Responds to Alnylam Complaint

CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Dicerna Pharmaceuticals, Inc. (NASDAQ:DRNA) today responded to a complaint filed yesterday by Alnylam Pharmaceuticals, Inc. in the Superior Court of Middlesex County, Massachusetts. Dicerna believes the complaint is meritless and that Alnylam precipitously filed its lawsuit based on assumptions rather than facts. Dicerna intends to vigorously defend all of the claims.

"Dicerna's technology is built firmly on its own research and innovation," noted Douglas Fambrough, Ph.D., chief executive officer of Dicerna, "Dicerna focuses on serious, life-threatening diseases involving the liver and genetically defined cancers for which patients have few or no treatment options available. Our RNAi-based therapeutics utilize our proprietary RNAi technologies, and not prior Merck research. We stand behind these technologies, and the company's record and practices for respecting IP rights, in order to develop and deliver life-changing therapies as efficiently as possible."

Earlier this year Alnylam indicated it was concerned about unspecified aspects of Dicerna's GalNAc delivery technologies. Dicerna then conducted a thorough investigation and confirmed that there has been no use of Merck/Alnylam confidential information at the company. Dicerna communicated the results of its investigation to Alnylam (one of many facts omitted from the complaint). Likewise, Dicerna communicated to Alnylam facts demonstrating that many of the insinuations in the Alnylam complaint are simply false, and others are unfounded speculation.
