Abstract: Described herein are compositions comprising liposome-based nanocarriers and associated drugs that selectively target bone marrow, minimize tumor delivery, and maintain high drug concentrations in bone marrow when compared to conventional systemic delivery. The compositions also selectively target lymph nodes and other reticuloendothelial system organs (e.g., spleen, e.g., liver), while minimizing delivery to the tumor in order to deliver drugs that prevent bone marrow suppression (BMS) or aid recovery post exposure to radiation. There are a wide range of scenarios for which such radiation protection is useful, e.g., protection from radiation delivered as part of cancer therapy, radiation from weapons, radiation from materials at a nuclear power plant or nuclear waste site, natural radiation in outer space (e.g., for astronauts), and the like. The described compositions are stable for prolonged periods of time, in some cases over a year in a kit formulation.
