1. A method of treating ovarian cancer in an individual by administering to the individual modified T cells, wherein the modified T cells are modified i) to express a chimeric antigen receptor (CAR), the CAR comprising a T cell immunoreceptor with immunoglobulin and tyrosine-based inhibitory motif (TIGIT) extracellular domain that can bind to poliovirus receptor (PVR), a CD28 segment, and a CD3ζ segment; and ii) to express and secrete a Bi-specific T cell engager (BiTE), wherein the BiTE includes a segment that can specifically bind to human Folate Receptor alpha (FRα) and a segment that that can specifically bind to a human CD3ε segment.
