IMPROVED NUCLEIC ACID LIPID PARTICLE FORMULATIONS

摘要

The present invention relates to lipid nanoparticles containing a biodegradable cationic lipid which provide improved delivery of active pharmaceutical ingredients, such as siRNA. In addition to the biodegradable cationic lipid the nanoparticles comprise a non-cationic lipid, polyethylne glycol dipalmitoylglycerol (PEG-DPG) and optionally a sterol.
