Patent ID: 11285169

Abstract:
Methods of reducing cytotoxicity of a chemotherapeutic agent to non-cancer cells by administering to a subject with cancer an effective amount of an agent that inhibits CD47 signaling and a DNA damaging agent, such as an anthracycline, topoisomerase inhibitor, or nucleotide synthesis inhibitor, are provided. Example disclosed methods reduce cardiotoxicity. In one example, the methods include administering to a subject with cancer an effective amount of a CD47 antisense morpholino oligonucleotide and an anthracycline such as doxorubicin. Methods of increasing cytotoxicity of a chemotherapeutic agent in cancer cells by administering to a subject with a tumor an effective amount of an agent that inhibits CD47 signaling and a DNA damaging agent such as an anthracycline, topoisomerase inhibitor, or nucleotide synthesis inhibitor, are also provided. In some embodiments, the inhibitor of CD47 signaling is administered to the subject before, during, or after the administration of the DNA damaging agent.
