Patents by Inventor Osiris MARROQUIN BELAUNZARAN

Osiris MARROQUIN BELAUNZARAN has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11807676
    Abstract: The invention relates to MHC-Ia open conformers as immunomodulatory agents, particularly in the treatment or prevention of cancer. The open conformer comprises or consists of a first and a second monomer, and each monomer comprises a HLA-heavy chain from the MHC-Ia molecules. The open conformer further comprises a protein stabilizing polypeptide sequence and optionally an amino acid linker. Further aspects of the invention provide combination medicaments comprising the MHC-Ia open conformers and immune checkpoint inhibitors. Furthermore, the invention relates to the use of MHC-Ia open conformers as immunomodulators, particularly in diseases where the interaction to diverse immunoregulatory receptors such as KIR3DL1, KIR3DL2, KIR3DL3, LILRB1, LILRB2, and PTPRJ modulates an immune response, and in diseases were the negative modulation of Tregs is a therapeutic strategy, e.g. infectious diseases.

  • Patent number: 11484572
    Abstract: The invention relates to a HLA-B27 Fc open conformer or a HLA-B27 Fc fusion protein for use in the treatment or prevention of cancer. The Fc open conformer comprises or consists of a first and a second monomer, and each monomer comprises a HLA-B27 chain. The Fc fusion protein further comprises a protein stabilizing polypeptide sequence and optionally an amino acid linker. Further aspects of the invention provide combination medicaments comprising the HLA-B27 Fc open conformer and immune checkpoint inhibitors.

  • Publication number: 20220339250
    Abstract: The invention relates to a HLA-B57 open conformer or a HLA-B57 Fc fusion protein for use in the treatment or prevention of cancer. The Fc open conformer comprises or consists of a first and a second monomer, and each monomer comprises a HLA-B57 chain. The Fc fusion protein further comprises a protein stabilizing polypeptide sequence and optionally an amino acid linker. Further aspects of the invention provide combination medicaments comprising the HLA-B57 Fc open conformer and immune checkpoint inhibitors and/or checkpoint agonist agents. Furthermore, the invention relates to the use of HLA-B57 open conformer as an immunomodulator, particularly in diseases where modulation of diverse immune cell components (e.g. cytotoxic CD8+T cells, Tregs) is a therapeutic strategy, e.g. infectious diseases.
