CAMBRIDGE, Mass.--(BUSINESS WIRE)--Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), a leading RNAi therapeutics company, announced today that it has filed a Clinical Trial Application (CTA) with the U.K. Medicines and Healthcare products Regulatory Agency (MHRA) to initiate a Phase I clinical trial with ALN-TTRsc, an RNAi therapeutic targeting transthyretin (TTR) for the treatment of TTR-mediated amyloidosis (ATTR). ALN-TTRsc is a subcutaneously administered RNAi therapeutic that comprises an siRNA conjugated to a triantennary N-acetylgalactosamine (GalNAc) ligand. GalNAc-siRNA conjugates are a proprietary Alnylam delivery platform and are designed to achieve targeted delivery of RNAi therapeutics to hepatocytes through uptake by the asialoglycoprotein receptor. ALN-TTRsc is the first GalNAc-siRNA to enter clinical development stages. Following approval of the CTA, Alnylam expects to initiate a Phase I study with ALN-TTRsc early in 2013 with data expected to be reported in mid-2013.
