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

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

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 relates 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.
