  • Patent number: 10751423
    Abstract: Disclosed are methods of treating cancer of the intraperitoneal cavity using compositions comprising nanoparticles without targeting agents. In addition, nanoparticles are described that comprise a highly toxic anticancer agent (e.g., an anticancer agent having an IC50 less than 1 nM) covalently bound via a linker to a triblock copolymer. Other nanoparticles that comprise Pt(IV) and an anticancer agent are also described. Also disclosed are nanoparticles comprising imaging agents non-covalently associated with a polymer, and methods of imaging cancer of the intraperitoneal cavity using compositions comprising nanoparticles without targeting agents.
