Abstract:
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.
Abstract:
Methods for determining dosage of HER2-targeted anthracycline -containing immunoliposomes are disclosed, as are methods of treating cancer patients with HER2- positive tumors using dosages so determined. Upon administration, the dosages share the low cardiotoxicity profile of standard dosages of non-immunoliposomal (untargeted), anthracycline -containing liposomes.
