COMBINATION THERAPIES FOR TREATING HER2-POSITIVE CANCERS THAT ARE RESISTANT TO HER2-TARGETED THERAPIES

摘要

Methods for treating cancer patients (e.g., cancer patients resistant or intolerant to pertuzumab and ado-trastuzumab emtansine) having HER2-positive tumors are disclosed. The methods comprise administering to a patient a therapeutically effective amount of a combination of a doxorubicin-loaded immunoliposome with a targeting moiety that is an anti-HER2 antibody that is not an inhibitor of HER2 signaling and an anti-cancer therapeutic comprising a doxorubicin-free anti-cancer therapeutic comprising a different anti-HER2 antibody.
