Lipid formulations for nucleic acid delivery

摘要

The present invention provides novel, stable lipid particles comprising one or more active agents or therapeutic agents, methods of making the lipid particles, and methods of delivering and/or administering the lipid particles. More particularly, the present invention provides stable nucleic acid-lipid particles (SNALP) comprising a nucleic acid (such as one or more interfering RNA), methods of making the SNALP, and methods of delivering and/or administering the SNALP.

1. A nucleic acid-lipid particle comprising:
(a) a nucleic acid; (b) a cationic lipid comprising from 50 mol % to 85 mol % of the total lipid present in the particle; (c) a non-cationic lipid comprising from 13 mol % to 49.5 mol % of the total lipid present in the particle; and (d) a conjugated lipid that inhibits aggregation of particles comprising from 0.5 mol % to 2 mol % of the total lipid present in the particle.
