Juno Therapeutics, Inc. (Juno) is a United States-based clinical-stage biopharmaceutical company. The Company is engaged in developing cell-based cancer immunotherapies based on its chimeric antigen receptor (CAR), and high-affinity T cell receptor (TCR), technologies to genetically engineer T cells to recognize and kill cancer cells. Through genetic engineering, the Company inserts a gene for a particular CAR or TCR construct into the T cell that enables it to better recognize cancer cells. Its CAR technology directs T cells to recognize cancer cells based on the expression of specific proteins located on the cell surface, whereas its TCR technology provides the T cells with a specific T cell receptor to recognize protein fragments derived from either the surface or inside the cell. The Company�s CD19 product candidates include JCAR015, JCAR017, and JCAR014. Its additional product candidates include CD22, L1CAM, MUC-16/IL-12, ROR-1 and WT-1.
