  • Patent number: 11879014
    Abstract: The present disclosure relates to use of an anti-CD25 antibody, not inhibiting IL-2-CD25 interaction, with enhanced binding to activating Fc gamma Rs that lead to effective depletion of tumor-infiltrating Treg cells and improved control of established tumors. Combination with anti-programmed cell death protein-1 antibodies further improves tumor rejection.
    Type: Grant

  • Publication number: 20230265200
    Abstract: The present disclosure relates to a method of treating a solid tumour, wherein said method involves the use of an antibody to CD25. In particular, the antibody to CD25 is optimized for depletion of regulatory T cells (Treg) within tumours. The present invention also provides novel anti-CD25 antibodies and their combination with other anti-cancer drugs, such as immune checkpoint inhibitors, compounds that target cancer antigens or the inhibitory Fc receptor FcyRllb (CD32b).

  • Publication number: 20230158073
    Abstract: The present invention provides an engineered T cell for use in a method of treatment of a proliferative disorder, wherein the engineered T cell has modulated expression of one or more genes selected from SIT1, SAMSN1, SIRPG, CD7, CD82, FCRL3, IL1RAP, FURIN, STOM, AXL, E2F1, C5ORF30, CLDND1, COTL1, DUSP4, EPHA1, FABP5, GFI1, ITM2A, PARK7, PECAM1, PHLDA1, RAB27A, RBPJ, RGS1, RGS2, RNASEH2A, SUV39H1, and TNIP3. Further provided are activity modulators of one or more proteins encoded by genes selected from SIT1, SAMSN1, SIRPG, CD7, CD82, FCRL3, IL1RAP, FURIN, STOM, AXL, E2F1, C5ORF30, CLDND1, COTL1, DUSP4, EPHA1, FABP5, GFI1, ITM2A, PARK7, PECAM1, PHLDA1, RAB27A, RBPJ, RGS1, RGS2, RNASEH2A, SUV39H1, and TNIP3 for use in a method of enhancing immunotherapy in a subject having a proliferative disorder. Also provided are related methods of treatment employing the engineered T cell and/or inhibitor.

  • Publication number: 20220241333
    Abstract: The present invention provides an engineered T cell for use in a method of treatment of a proliferative disorder in a mammalian subject, wherein the T cell has been engineered (i) to overexpress BLIMP1 and/or (ii) to knock-out or decrease expression of BCL6. Further provided is a BCL6 inhibitor for use in a method of enhancing immunotherapy in a subject having a proliferative disorder. Also provided are related methods of treatment employing the engineered T cell and/or BCL6 inhibitor.

  • Publication number: 20200000904
    Abstract: The present invention relates to a method for identifying a truncal neo-antigen in a tumour from a subject which comprises the steps of: i) determining mutations present in a sample isolated from the tumour; and ii) identifying a truncal mutation which is a mutation present in essentially all tumour cells; and iii) identifying a truncal neo-antigen, which is an antigen encoded by a sequence which comprises the truncal mutation.
