摘要： Described herein methods of using antigen-binding constructs to treat HER2+ tumors in a subject such as breast, lung, or head and neck tumors. In some aspects, the tumor volume in the subject after receiving at least seven doses of the antigen binding construct is less than the tumor volume of a control subject receiving an equivalent amount of trastuzumab. In some aspects, the survival of the subject receiving the antigen binding construct is increased as compared to a control subject receiving an equivalent amount of a non-specific control antibody or as compared to a control subject not receiving treatment.

摘要： The present invention concerns compositions and methods of use of bispecific antibodies comprising at least one binding site for Trop-2 (EGP-1) and at least one binding site for CD3. The bispecific antibodies are of use for inducing an immune response against a Trop-2 expressing tumor, such as carcinoma of the esophagus, pancreas, lung, stomach, colon, rectum, urinary bladder, breast, ovary, uterus, kidney or prostate. The methods may comprising administering the bispecific antibody alone, or with one or more therapeutic agents such as antibody-drug conjugates, interferons (preferably interferon-α), and/or checkpoint inhibitor antibodies. The bispecific antibody is capable of targeting effector T cells, NK cells, monocytes or neutrophils to induce leukocyte-mediated cytotoxicity of Trop-2+ cancer cells. The cytotoxic immune response is enhanced by co-administration of interferon, checkpoint inhibitor antibody and/or ADC.

摘要： The present invention relates to methods and compositions for pretargeting delivery of alpha-emitting radionuclides, such as 213Bi or 225AC to a target cell or tissue, such as a cancer cell or a tumor. In preferred embodiments, the pretargeting method comprises: a) administering a bispecific antibody comprising at least one binding site for a tumor-associated antigen (TAA) and at least one binding site for a hapten; and b) administering a hapten-conjugated targetable construct that is labeled with an alpha-emitting radionuclide. More preferably, the bispecific antibody is rapidly internalized into the target cell, along with the radionuclide. In most preferred embodiments, the bispecific antibody is made as a dock-and-lock (DNL) complex.
