CAMBRIDGE, Mass.--(BUSINESS WIRE)--Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), a leading RNAi therapeutics company, announced today that it has discovered a key mechanism related to the systemic delivery of RNAi therapeutics using lipid nanoparticles (LNPs). The new pre-clinical research was presented at the “Advances in Biopharmaceuticals” Keystone Symposium held January 8-13, 2010 in Midway, Utah, and was performed in collaboration with scientists at the Max Planck Institute of Molecular Cell Biology and Genetics. The new data document a key mechanism for endogenous targeting of LNPs to the liver, provide alternative targeting strategies for the hepatic delivery of RNAi therapeutics, and highlight potential targeting approaches for delivery to non-hepatic tissues and cell types.
