  • Publication number: 20230160881
    Abstract: Methods for and uses of cell free RNA for determining prognosis of a cancer immunotherapy or for identifying a location of a tumor that is susceptible to a cancer immunotherapy are disclosed. A bodily fluid of a cancer patient treated with the cancer immunotherapy is obtained and cell free RNA is isolated from the bodily fluid. The amount of cell free RNA of at least one cancer related gene in the bodily fluid of the patient is identified, and the quantity of the cell free RNA is associated with the prognosis of the cancer immunotherapy. In some embodiments, the cell free RNA of at least one cancer related gene is cell-type specific or tumor-specific such that characterization of the cell free RNA identifies the location of the tumor.

  • Publication number: 20230134725
    Abstract: Chimeric molecules and molecule complexes that include an Fc portion of an antibody and an immunomodulatory portion and uses thereof are contemplated. Typically, the chimeric molecule comprises at least two immune effectors, for example, IL-15 antagonist and PD-L1 binding domain. It is contemplated that a tumor cell or an immune competent cell can be exposed to the chimeric molecule to increase the effectiveness tumor cell lysis via an antibody-dependent cell-mediated cytotoxicity.

  • Patent number: 11626187
    Abstract: Systems and methods are presented that allow for predicting treatment response of a tumor to a checkpoint inhibitor. In one exemplary aspect, the treatment response is directly associated with a relatively high number of patient- and tumor-specific immunologically visible neoepitopes. Specific mutational patterns in the nucleic acid encoding the neoepitope may be further indicative of treatment response.

  • Patent number: 11623001
    Abstract: Methods and compositions for preparation and use of recombinant viruses or other recombinant expression systems are presented in which neoepitopes are first identified in a patient- and cancer-specific manner and then further filtered by HLA-match to the patient. Selected neoepitopes are then expression using sequence elements that direct the expressed neoepitope to the HLA-type (MHC-I and/or MHC-II subtype) that has desirable affinity to the filtered neoepitope.

  • Publication number: 20230086390
    Abstract: Disclosed herein are methods for inducing immunity against a virus such as a coronavirus in the mucosal tissue of a patient, include administering a vaccine composition to the patient by oral administration (e.g., nasal injection, nasal inhalation, oral inhalation, and/or oral ingestion). Also disclosed are compositions for assaying the presence of antiviral antibodies induced by the administered vaccine or the presence of viral proteins in a saliva sample include a stabilizing solution and may also include the use of aragonite particle beads. Compositions and methods are presented for prevention and/or treatment of a coronavirus disease wherein the composition comprises a recombinant entity. The recombinant entity is bivalent, comprising a nucleic acid encoding a coronavirus 2 nucleocapsid protein CoV2 nucleocapsid protein fused to an endosomal targeting sequence, and a nucleic acid encoding a CoV2 spike protein sequence optimized for cell surface expression.

  • Patent number: 11585805
    Abstract: Ex vivo determination of increased tumor immunogenicity of a tumor biopsy is used as a guide to identify immunotherapy of a tumor in a patient. Most preferably, the ex vivo tests will include exposure of biopsy samples to stress conditions to produce pretreated tumor cells that are then assayed with immune competent cells for increased activation or activity. Test conditions include exposure of the biopsy samples to immune stimulatory compositions, antibodies against neoepitopes, and/or modified cells, and an increase of immunogenicity is preferably determined by their exposure to T cells and/or NK cells.

  • Publication number: 20220375085
    Abstract: Techniques are provided for determining a cell count within a whole slide pathology image. The image is segmented using a global threshold value to define a tissue area. A plurality of patches comprising the tissue area are selected. Stain intensity vectors are determined within the plurality of patches to generate a stain intensity image. The stain intensity image is iteratively segmented to generate a cell mask using a local threshold value that is and gradually reduced after each iteration. A chamfer distance transform is applied to the cell mask to generate a distance map. Cell seeds are determined on the distance map. Cell segments are determined using a watershed transformation, and a whole cell count is calculated for the plurality of patches based on the cell segments. A client device may be configured for real-time cell counting based on the whole cell count.
