The present invention provides compositions and methods for the delivery of therapeutic agents to cells. In particular, these include novel cationic lipids and nucleic acid-lipid particles that provide efficient encapsulation of nucleic acids and efficient delivery of the encapsulated nucleic acid to cells in vivo. The compositions of the present invention are highly potent, thereby allowing effective knock-down of a specific target protein at relatively low doses. In addition, the compositions and methods of the present invention are less toxic and provide a greater therapeutic index compared to compositions and methods previously known in the art.
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.

The present invention provides compositions and methods for the delivery of interfering RNAs such as siRNAs that silence APOB expression in cells such as liver cells. In particular, the nucleic acid-lipid particles provide efficient encapsulation of nucleic acids and efficient delivery of the encapsulated nucleic acid to cells such as liver cells in vivo. The compositions of the present invention are highly potent, thereby allowing effective knock-down of APOB at relatively low doses. In addition, the compositions and methods of the present invention are less toxic and provide a greater therapeutic index compared to compositions and methods previously known in the art.
