Patents by Inventor Mark D. Ayers

Mark D. Ayers 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).

  • Publication number: 20220380854
    Abstract: The invention relates to (i) an angiogenesis gene signature and (ii) a monocytic myeloid-derived suppressor cell (mMDSC) gene signature that are each predictive of patient response to treatment with a PD-1 antagonist, wherein the angiogenesis signature comprises five or more genes. More specifically, a lower angiogenesis score is associated with favorable response to a PD-1 antagonist in a patient with cancer. Similarly, a lower mMDSC score is associated with favorable response to a PD-1 antagonist in a patient with cancer. Also provided are methods of treating a cancer patient with a PD-1 antagonist that were identified as either (i) positive for the angiogenesis gene signature biomarker of the invention or (ii) positive for the mMDSC gene signature biomarker of the invention.

  • Patent number: 11377693
    Abstract: A gene expression platform, which is a combination of a set of genes that are correlated with response to a PD-1 antagonist in multiple tumor types and a normalization gene set, is disclosed. A method and system of using the gene expression platform to derive gene signature biomarkers of anti-tumor response to a PD-1 antagonist and to test patient samples for predictive gene signature biomarkers are also disclosed.

  • Publication number: 20220112564
    Abstract: The invention relates to a stromal/EMT/TGF? signature that is predictive of patient response to treatment with a PD-1 antagonist, wherein the stromal/EMT/TGF? signature comprises five or more genes selected from Table 1 disclosed herein. More specifically, a lower stromal/EMT/TGF-? score is associated with favorable response to a PD-1 antagonist in a patient with cancer. Also provided are methods of treating a cancer patient with a PD-1 antagonist that were identified as positive for the stromal/EMT/TGF? biomarker of the invention. The disclosure also provides methods and kits for testing tumor samples for the biomarkers.

  • Publication number: 20100009358
    Abstract: The invention relates to compositions, kits, and methods for detecting, characterizing, preventing, and treating human breast cancers. A variety of newly identified markers are provided, wherein changes in the levels of expression of one or more of the markers is correlated with the presence of breast cancer.

  • Patent number: 7195868
    Abstract: The present invention is directed to the identification of markers that can be used to determine whether tumors are sensitive or resistant to a therapeutic agent. The present invention is also directed to the identification of therapeutic targets. The invention features a number of “sensitivity markers.” These are markers that are expressed in most or all cell lines that are sensitive to treatment with an agent and which are not expressed (or are expressed at a rather low level) in cells that are resistant to treatment with that agent. The invention also features a number of “resistance markers.” These are markers that are expressed in most or all cell lines that are resistant to treatment with an agent and which are not expressed (or are expressed at a rather low level) in cells that are sensitive to treatment with that agent.
