  • Compositions for targeted delivery of siRNA
    Patent number: 10316316
    Abstract: The present invention is directed compositions for targeted delivery of RNA interference (RNAi) polynucleotides to hepatocytes in vivo. Targeted RNAi polynucleotides are administered together with co-targeted delivery polymers. Delivery polymers provide membrane penetration function for movement of the RNAi polynucleotides from outside the cell to inside the cell. Reversible modification provides physiological responsiveness to the delivery polymers.
    Type: Grant
    Filed: April 19, 2016
    Date of Patent: June 11, 2019
    Assignee: Arrowhead Pharmaceuticals, Inc.
