  • Publication number: 20240100166
    Abstract: The present invention provides novel, serum-stable lipid particles comprising one or more active agents or therapeutic agents, methods of making the lipid particles, and methods of delivering and/or administering the lipid particles. More particularly, the present invention provides serum-stable nucleic acid-lipid particles (SNALP) comprising a nucleic acid (e.g., one or more interfering RNA molecules), methods of making the SNALP, and methods of delivering and/or administering the SNALP (e.g., for the treatment of cancer). In particular embodiments, the present invention provides tumor-directed lipid particles that preferentially target solid tumors. The tumor-directed formulations of the present invention are capable of preferentially delivering a payload such as a nucleic acid to cells of solid tumors compared to non-cancerous cells.

  • Publication number: 20230165973
    Abstract: The present invention provides compositions comprising mRNA molecules encapsulated within lipid particles. The lipid particles comprise a cationic lipid, a non-cationic lipid, and an mRNA molecule that is encapsulated within the lipid particle. The compositions are useful, for example, to introduce the mRNA molecules into a human subject where they are translated to produce a polypeptide that functions to ameliorate one or more symptoms of a disease. The invention also provides cationic lipids that are useful for preparing the compositions of the invention.

  • Patent number: 11318098
    Abstract: The present invention provides apparatus and processes for producing liposomes. By providing a buffer solution in a first reservoir, and a lipid solution in a second reservoir, continuously diluting the lipid solution with the buffer solution in a mixing chamber produces a liposome. The lipid solution preferably comprises an organic solvent, such as a lower alkanol.
