  • Patent number: 11766478
    Abstract: Described herein are methods comprising administering to a mammalian subject an effective amount of an annexin chimeric fusion protein, wherein the annexin chimeric fusion protein comprises at least one immunogenic antigen, thereby enhancing the antigen specific immune response relative to administration of the immunogenic antigen alone. Methods and kits for treating or preventing recurrence of hyper proliferating diseases, e.g., cancer, are described. A method may comprise priming a mammal by administering to the mammal an effective amount of a chemotherapeutic agent and boosting the mammal by administering to the mammal an effective amount of an annexin chimeric fusion.

  • Patent number: 11285197
    Abstract: Mesothelin can be used as an immunotherapeutic target. It induces a cytolytic T cell response. Portions of mesothelin which induce such responses are identified. Vaccines can be either polynucleotide- or polypeptide-based. Carriers for raising a cytolytic T cell response include bacteria and viruses. A mouse model for testing vaccines and other anti-tumor therapeutics and prophylactics comprises a strongly mesothelin-expressing, transformed peritoneal cell line.
