Abstract: A composition comprising liposomes comprising a lipid layer defining an internal aqueous compartment, an anthracycline drug entrapped in the internal aqueous phase and mitomycin C prodrug incorporated into the lipid layer is described.

Abstract: The present invention is based on a finding of an unexpected synergistic and safe combination of antineoplastic agents which when administered in combination provides greater efficacy than the single agents alone. Accordingly, a method of treating neoplasia in a subject in need of treatment is provided, by administering to the subject an amount of a prodrug of mitomycin C that yields a therapeutically effective amount of mitomycin C, in combination with an amount of a chemotherapeutic agent. In one embodiment, the prodrug of mitomycin C is a liposomal-prodrug of mitomycin C. Together, the prodrug of mitomycin C and chemotherapeutic agent provide a synergistic antineoplastic effect.

Abstract: A method of treating neoplasia in a subject in need of treatment is provided by administering to the subject an amount of a prodrug of mitomycin C that yields a therapeutically effective amount of mitomycin C, in combination with radiation therapy. In one embodiment, the prodrug of mitomycin C is a liposomal-prodrug of mitomycin C. Together, the prodrug of mitomycin C and radiation therapy provide a synergistic antineoplastic effect.
