  • Publication number: 20230416737
    Abstract: Described are RNAi agents, compositions that include RNAi agents, and methods for inhibition of a double homeobox 4 (DUX4) gene. The DUX4 RNAi agents and RNAi agent conjugates disclosed herein inhibit the expression of a DUX4 gene. Pharmaceutical compositions that include one or more DUX4 RNAi agents, optionally with one or more additional therapeutics, are also described. Delivery of the described DUX4 RNAi agents to skeletal muscle cells in vivo, provides for inhibition of DUX4 gene expression and a reduction in DUX4 levels, which can provide a therapeutic benefit to subjects, including human subjects, suffering from certain skeletal muscle-related diseases or disorders including Facioscapulohumeral Muscular Dystrophy (FSID).

  • Publication number: 20230265429
    Abstract: The present disclosure relates to delivery vehicles that specifically and efficiently direct payloads to skeletal muscle cells in a subject, in vivo. The delivery vehicles disclosed herein include targeting ligands (such as compounds that have affinity for integrins, including alpha-v-beta-6) and pharmacokinetic/pharmacodynamic (PK/PD) modulators, to facilitate the delivery of payloads to cells, including to skeletal muscle cells. Suitable payloads for use in the delivery vehicles disclosed herein include RNAi agents, which can be linked or conjugated to the delivery vehicles, and when delivered in vivo, provide for the inhibition of gene expression in skeletal muscle cells. Pharmaceutical compositions that include the skeletal muscle cell delivery vehicle are also described, as well as methods of use for the treatment of various diseases and disorders where delivery of a therapeutic payload to a skeletal muscle cell is desirable.

  • Publication number: 20230226193
    Abstract: Disclosed herein are compounds according to Formula (I) comprising PK/PD modulators for delivery of oligonucleotide-based agents, e.g., double stranded RNAi agents, to certain cell types, such for example skeletal muscle cells, in vivo. The PK/PD modulators disclosed herein, when conjugated to an oligonucleotide-based therapeutic or diagnostic agent, such as an RNAi agent, can enhance the delivery of the composition to the specified cells being targeted to facilitate the inhibition of gene expression in those cells.
