  • Patent number: 10259854
    Abstract: The field of the present invention relates to genetically engineered fusion molecules, methods of making said fusion molecules, and uses thereof in anti-tumor immunotherapies. More specifically, the present invention relates to fusion molecule constructs wherein a tumor associated antigen (TAA) antibody (Ab) serves as a targeting moiety to selectively deliver a cytokine to a tumor cell for purposes of killing or inhibiting the growth or proliferation of said tumor cell. In various embodiments, the engineered fusion molecules comprise a TAA Ab fused to an interferon-alpha (IFN-?) mutant molecule. The engineered Ab-IFN-? mutant fusion molecules of the present invention demonstrate improved therapeutic index and preserved or increased efficacy as compared to Ab-wildtype IFN-? fusion molecules, and/or demonstrate improved PK properties as compared to Ab-wildtype IFN-? fusion molecules.

  • Patent number: 9783589
    Abstract: The field of the present invention relates to genetically engineered fusion molecules, methods of making said fusion molecules, and uses thereof for treatment of autoimmune diseases. More specifically, the present invention provides novel genetically engineered fusion molecules comprising an interferon (IFN) molecule attached to an antibody (Ab) which targets an antigen which is differentially expressed or up-regulated on activated T cells as compared to resting T cells, wherein the fusion molecule when contacted to an activated T cell results in induced apoptosis and programmed cell death or impairment of functions of said activated T cell.

  • Patent number: 9534056
    Abstract: The field of the present invention relates to genetically engineered fusion molecules, methods of making said fusion molecules, and uses thereof in anti-tumor immunotherapies. More specifically, the present invention relates to engineered fusion molecules comprising an antibody (Ab) which can target tumor cells (e.g., RITUXIN®), fused to one or more biologic moieties capable of inducing apoptosis in tumor cells, e.g., tumor necrosis factor super family (TNFSF) member ligands such as TNF-?, CD40L, CD95L (also “FasL/Apo-1L”) and TRAIL/Apo-2L. Importantly, the engineered fusion molecules of the present invention retain the death-inducing properties of the biologic moiety at optimum concentrations and with reduced systemic toxicities.
