Abstract: The present disclosure provides particles with a polymeric core containing a pharmaceutically active agent; and an antibody fragment conjugated to the surface of the particle, wherein the antibody fragment targets an endogenous immune cell subset (e.g., an endogenous T-cell or a myeloid-derived suppressor cell). The present invention provides methods for forming and methods for using the particles. The particles described herein may be useful in treating and/or preventing proliferative disease, inflammatory disease, or neoplastic disorders (e.g., cancer, autoimmune diseases). Also provided in the present disclosure are pharmaceutical compositions, kits, methods, and uses including or using a particle described herein.
