The present invention provides compositions comprising siRNA molecules that target Marburg virus (MARV) gene expression, lipid particles comprising one or more (e.g., a combination) of the siRNA molecules, and methods of delivering and/or administering the lipid particles, for the purposes of treating MARV infection.

Compositions and methods for silencing marburg virus gene expression

The present invention provides compositions comprising therapeutic nucleic acids (e.g., interfering RNA such as siRNA) that target Ebola virus (EBOV) gene expression and methods of using such compositions to silence EBOV gene expression. More particularly, the invention provides unmodified and chemically modified interfering RNA which silence EBOV gene expression and methods of use thereof, e.g., for preventing or treating EBOV infections caused by one or more EBOV species such as Zaire EBOV. The invention also provides serum-stable nucleic acid-lipid particles comprising one or more interfering RNA molecules, a cationic lipid, and a non-cationic lipid, which can further comprise a conjugated lipid that inhibits aggregation of particles. Methods of silencing EBOV gene expression by administering one or more interfering RNA molecules to a mammalian subject are also provided.

Compositions and methods for silencing ebola virus gene expression

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.

Compositions and methods for silencing apolipoprotein B

Compositions and methods for silencing Ebola virus gene expression

The present invention provides compositions comprising therapeutic nucleic acids such as interfering RNA (e.g., dsRNA such as siRNA) that target Lassa virus (LASV) or tissue factor (TF) gene expression, lipid particles comprising one or more (e.g., a cocktail) of the therapeutic nucleic acids, methods of making the lipid particles, and methods of delivering and/or administering the lipid particles (e.g., for treating hemorraghic fever).

Compositions and methods for silencing genes involved in hemorrhagic fever

The present invention provides compositions and methods for the delivery of interfering RNAs that silence APOB expression to 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 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.
