The invention relates to a method of gene silencing, comprising administering to a cell or a subject in need thereof a therapeutically effective amount of the lipophilic moieties-conjugated double-stranded iRNAs at one or more internal positions on at least one strand, optionally via a linker or carrier.

Extrahepatic delivery

The present invention relates to a cationic lipid having one or more biodegradable groups located in a lipidic moiety (e.g., a hydrophobic chain) of the cationic lipid. These cationic lipids may be incorporated into a lipid particle for delivering an active agent, such as a nucleic acid. The invention also relates to lipid particles comprising a neutral lipid, a lipid capable of reducing aggregation, a cationic lipid of the present invention, and optionally, a sterol. The lipid particle may further include a therapeutic agent such as a nucleic acid.

Biodegradable lipids for the delivery of active agents

One aspect of the present invention relates to double-stranded RNA (dsRNA) agent capable of inhibiting the expression of a target gene. The antisense strand of the dsRNA molecule comprises at least one thermally destabilizing nucleotide occurring at a seed region; the dsRNA comprises at least four 2'-fluoro modifications, and the sense strand of the dsRNA molecule comprises ligand, wherein the ligand is an ASGPR ligand. Other aspects of the invention relate to pharmaceutical compositions comprising these dsRNA molecules suitable for therapeutic use, and methods of inhibiting the expression of a target gene by administering these dsRNA molecules, e.g., for the treatment of various disease conditions.

Modified RNA agents with reduced off-target effect

The present invention relates, in general to, compounds, compositions and methods useful for modulating gene expression of multiple target nucleic acids by a single chemical entity.

Multi-targeted single entity conjugates

The present invention relates to ligand conjugates of oligonucleotides (e.g., iRNA agents) and methods for their preparation. The ligands are derived primarily from monosaccharides These conjugates are useful for the in vivo delivery of oligonucleotides.

Oligonucleotide-ligand conjugates and process for their preparation

The present invention provides a phosphorothioate-modified oligonucleotide comprising a structure shown below: The present invention also provides a phosphorothioate-modified oligonucleotide comprising a structure having formula (CIII):

Carbohydrate conjugates as delivery agents for oligonucleotides

One aspect of the present invention relates to a double stranded iRNA agent comprising an antisense strand which is complementary to a target gene; a sense strand which is complementary to said antisense strand; and one or more lipophilic moieties conjugated to one or more internal positions on at least one strand, optionally via a linker or carrier. Another aspect of the invention relates to a method of gene silencing, comprising administering to a cell or a subject in need thereof a therapeutically effective amount of the lipophilic moieties-conjugated double-stranded iRNAs.

This disclosure relates to an improved process for the preparation of carbohydrate conjugates. The disclosure also relates to carbohydrate conjugated iRNA agents comprising these carbohydrate conjugates, which have improved purity and are advantageous for the in vivo delivery of the iRNA agents.

Carbohydrate conjugate RNA agents and process for their preparation

The invention relates to RNAi agents, e.g., double stranded RNAi agents, targeting the Serpina1 gene, and methods of using such RNAi agents to inhibit expression of Serpina1 and methods of treating subjects having a Serpina1 associated disease, such as a liver disorder.

Serpina1 iRNA compositions and methods of use thereof

The present invention provides a modified RNAi agent comprising a sense strand and an antisense strand, wherein the antisense strand targets an HBV mRNA; all of the nucleotide sugars of the RNAi agent are 2'-modified; and at least one of the sense and antisense strands is conjugated to at least one targeting ligand that comprises two or more building blocks connected to a biantennary or triantennary branched linker, optionally via one or more linking groups.

The present invention relates to a chirally-modified dsRNA agent capable of inhibiting the expression of a target gene. The sense and antisense strands of chirally-modified dsRNA agent independently or in combination comprises one or more site specific-site specific/position specific, chirally-modified internucleotide linkages.
