  • Patent number: 10266484
    Abstract: The present invention relates to a cationic lipid having one or more biodegradable groups located in the mid- or distal section of 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.

  • Publication number: 20190099493
    Abstract: The present invention provides targeting lipids of structure where L100 is a lipid, lipophile, alkyl, alkenyl or alkynyl, L101 is a ligand or —CH2CH2(OCH2CH2)pO(CH2)qCH2-ligand, p is 1-1000, and q is 1-20. In addition, the invention provides compositions and methods for the delivery of therapeutic agents to cells. In particular, these include novel lipids and nucleic acid-lipid particles that provide efficient encapsulation of nucleic acids and efficient delivery of the encapsulated nucleic acid to cells in vivo.
