  • Patent number: 11696953
    Abstract: Provided herein are branched poly(beta-amino esters) (PBAE) useful as vehicles for the delivery of therapeutic agents, such as nucleic acids. The disclosed polymers form stable compositions, and are suitable for the delivery of therapeutic agents via nebulization. Compositions of the disclosed polymers are capable of delivering therapeutic agents such as mRNA to lung epithelial cells.
    Type: Grant
    Filed: September 7, 2022
    Date of Patent: July 11, 2023
    Assignee: Massachusetts Institute of Technology
    Inventors: Daniel Griffith Anderson, Kevin John Kauffman, James C. Kaczmarek, Asha Kumari Patel
  • Patent number: 11608412
    Abstract: The present disclosure relates to improvements in the selection and formulation of PBAE polymers using a design of experiment approach, in which statistical methods are used to limit possible experimental conditions. The present disclosure relates to improved PBAE polymers and formulations.

  • Publication number: 20210388196
    Abstract: Disclosed are methods, compositions, reagents, systems, and kits to prepare and utilize poly (?-amino ester) (PBAE) polymers, which are synthesized via Michael addition reactions of diacrylates and amines disclosed herein. Various embodiments utilize lactones and lactone derivatives to generate the diacrylate compounds. The PBAE polymers are shown to be effective biodegradable carriers for the delivery of an agent such as an organic molecule, inorganic molecule, nucleic acid, protein, peptide, polynucleotide, targeting agent, an isotopically labeled chemical compound, vaccine, or an immunological agent.
