  • Publication number: 20170080087
    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.

  • Publication number: 20170049767
    Abstract: Combination therapies for treating cancer comprising administration of a topoisomerase-1 inhibitor and a PARP inhibitor are provided. The topoisomerase-1 inhibitor can be delivered as a liposomal formulation that provides for prolonged accumulation of the topoisomerase-1 inhibitor within a tumor relative to outside of the tumor. Therapeutic benefit can thereby be obtained by delaying the administration of the PARP inhibitor after each administration of a liposomal irinotecan formulation until the accumulation of the topoisomerase inhibitor in the tumor is sufficiently greater than outside the tumor to result in increased efficacy of the PARP inhibitor and topoisomerase inhibitor within the tumor, while reducing the peripheral toxicity of the combination therapy. The therapies disclosed herein are useful in the treatment of human cancers with solid tumors, including cervical cancer.

  • Patent number: 9458245
    Abstract: Provided herein are tandem Fcs and tandem Fc antibodies (“TFcAs”), e.g., tandem Fc bispecific antibodies (“TFcBAs”), which comprise one or at least two binding sites that specifically bind to one or more cell surface receptors. The binding sites are connected through a TFc, which TFc comprises a first Fc region and a second Fc region, wherein the first and the second Fc regions are linked through a TFc linker to form a contiguous polypeptide and dimerize to form an Fc dimer. Exemplary TFcBAs bind to the cell surface receptors c-Met and EpCam and inhibit signal transduction through the cell surface receptor(s) for which the binding sites of the TFcBA are specific.
