Patent number: 10335420Abstract: An aqueous tumor-targeting liposome nanoparticle composition comprises an aqueous dispersion of liposome nanoparticles. The nanoparticles preferably encapsulate an anti-cancer chemotherapeutic agent, which can be added to a pre-formed liposome composition or can be incorporated in the liposomes during the formation of the liposomes. The liposome nanoparticles comprise a legumain-targeting lipid admixed with one or more other micelle or vesicle-forming lipid materials in the form of nanoparticulate liposomes dispersed in an aqueous carrier. A preferred tumor-targeting liposome nanoparticle composition comprises a legumain-targeting lipid component and polyethylene glycol-conjugated lipid component. The legumain-targeting lipid component comprising a hydrophobic lipid portion covalently attached to a legumain-binding moiety.Type: GrantFiled: April 24, 2017Date of Patent: July 2, 2019Assignee: The Scripps Research InstituteInventors: Ralph A. Reisfeld, Rong Xiang, Yunping Luo, Debbie Liao, Ze Liu, Tingmei Chen, Si Chen, Dan Lu

Publication number: 20150175996Abstract: The present invention provides a DNA composition comprising a DNA minigene construct that encodes for a polypeptide comprising a plurality of immunogenic fragments of a cysteine endopeptidase that is expressed in tumor-associated cells. The immunogenic fragments are joined together serially by a linker peptide between each successive fragment in the polypeptide. The polypeptide is capable of eliciting an immune response against the tumor-associated cells, is expressible in immune cells, and is incorporated in a pharmaceutically acceptable carrier.Type: ApplicationFiled: March 3, 2015Publication date: June 25, 2015Inventors: Ralph A.
