In certain embodiments a platform technology for the facilitating immune therapy in the treatement of cancer is provided. In certain embodiments nanocarriers are provided that facilitate delivery of an IDO pathway inhibitor in conjunction with an inducer of cell death (ICD-inducer). In certain embodiments the IDO inhibitor is conjugated to a component of a lipid bilayer forming a nanovesicle. In still another embodiment, methods and compositions are provided where an ICD-inducing agent (e.g., doxirubicin, oxaliplatin, etc.) and an IDO pathway inhibitor (e.g., an IDO inhibitor -prodrug) are integrated into a nanocarrier (e.g. a lipid-bilayer (LB) -coated nanoparticle), that allows systemic delivery to orthotopic pancreatic cancer site.
