  • Publication number: 20220378889
    Abstract: The invention relates to improved strategies, compositions, and methods for producing neoplasia vaccines and for their use in methods of treating cancer in a patient. In aspects, a method of treating cancer comprises: (a) administering an effective amount of one or more of the instantly-disclosed peptides or polypeptides comprising one or more identified shared neo-epitopes (including peptides or polypeptide comprising one or more peptides or polypeptides from Table A, B, and/or C and/or fragments and variants thereof); and subsequently (b) administering an effective amount of one or more of the instantly-disclosed subject-specific peptides or polypeptides comprising one or more identified subject-specific neo-epitopes. The peptides or polypeptides administered in step (a) and in step (b) are designed to exclude neo-epitopes that are known or determined (e.g.

  • Publication number: 20220362365
    Abstract: The present invention relates to improved strategies, compositions, and methods for producing shared neoplasia vaccines, including “off the shelf” pre-furnished shared neo-epitope warehouses, which can be used to enable the rapid production of bladder cancer neoantigen-based vaccines.

  • Publication number: 20220125900
    Abstract: The invention provides improved strategies, prognostic indicators, compositions, and methods for producing personalized neoplasia vaccines. More particularly, embodiments of the present disclosure relate to the identification of neoplasia-specific neo-epitopes to predict survival and to identify and design subject-specific neo-epitopes, further assessing the identified neo-epitopes encoded by said mutations to identify neo-epitopes that are known or determined, or predicted to engage regulatory T cells and/or other detrimental T cells (including T cells with potential host cross-reactivity and/or anergic T cells), and excluding such neo-epitopes that are known, determined, or predicted) to engage regulatory T cells and/or other detrimental T cells (including T cells with potential host cross-reactivity and/or anergic T cells) from the subject-specific neo-epitopes that are to be used in personalized neoplasia vaccines.
