Adeno-associated virus mediated B7.1 vaccination synergizes with angiostatin to eradicate disseminated liver metastatic cancers

摘要

The present invention provides adeno-associated viral (AAV) vectors encoding an angiostatin protein ("AAV-angiostatin vector") and/or a costimulatory molecule B7.1 ("AAV-B7.1 vector"). The AAV-angiostatin vector can be administered to a subject, alone or in combination, sequentially or simultaneously, with a AAV-B7.1 vector for treatment, management or prevention of metastatic tumors. Pharmaceutical compositions and vaccines comprising the AAV-angiostatin vector and/or the AAV-B7.1 vector and methods of manufacturing are also described. Administration of AAV-angiostatin and AAV-B7.1 vectors by intraportal and muscular injections are also provided.
