Patent number: 10259854Abstract: 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.Type: GrantFiled: November 28, 2016Date of Patent: April 16, 2019Assignee: ImmunGene IncInventors: Iqbal Grewal, Sanjay Khare, Michael Gresser, Rashid Syed
