1. An isolated engineered extracellular vesicle comprising a first antigen binding domain that comprises an anti-EGFR scFv antibody fragment and a second antigen binding domain that comprises an anti-CD3 scFv antibody fragment and, the first and second antigen binding domains being fused to one or more extracellular vesicle addressing domains expressed on the surface of the vesicle, wherein the one or more extracellular vesicle addressing domain comprises platelet-derived growth factor receptor (PDGFR) transmembrane domain.
