Abstract
Finding biologically relevant cancer markers is key to developing an effective treatment. Once specific antigens have been identified that are present on the cell population responsible for propagating tumors, T cells can be genetically altered to target these antigens and then used for personalized T cell therapy. A method to identify and select peptide antigens that effectively associate with and are presented by host HLA surface molecules originating from tumor cells responsible for the persistence and propagation of a cancer has been developed. The system of using these data to produce T cells engineered to express T cell receptors recognizing the peptide antigens is used in the production of a personalized adoptive T cell therapy for cancer that eliminates the cells capable of tumor propagation and cancer progression. The system is especially useful in the production of cancer treatments to achieve complete durable remission of cancers of epithelial origin.
