Abstract
The present invention provides novel, stable lipid particles having a non-lamellar structure and comprising one or more active agents or therapeutic agents, methods of making such lipid particles, and methods of delivering and/or administering such lipid particles. More particularly, the present invention provides stable nucleic acid-lipid particles (SNALP) that have a non-lamellar structure and that comprise a nucleic acid (such as one or more interfering RNA), methods of making the SNALP, and methods of delivering and/or administering the SNALP.
Claims22
A composition comprising:
- a plurality of nucleic acid-lipid particles, wherein each particle in the plurality of particles comprises:
- (a) a nucleic acid;
- (b) a cationic lipid;
- (c) a non-cationic lipid;
- and
- (d) a conjugated lipid that inhibits aggregation of particles,
- wherein at least about 95% of the particles in the plurality of particles are electron-dense.
