Patricia Ohana has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20250064784
    Abstract: A liposome composition comprising a lipophilic prodrug of mitomycin C having an improved pharmacokinetic profile is described. A method for preparing the composition with a solvent system comprised of ethanol and tertiary butanol mixed at an adequate ratio is also described. In an embodiment, the liposome composition is a population of lipid nanoparticles and a pharmaceutically acceptable vehicle, wherein the population of lipid nanoparticles is comprised of a first fraction of spherical liposomes and a second fraction of rod-shaped lipid nanoparticles, where the second fraction is less than about 15% of the population of lipid nanoparticles.

  • Patent number: 10080807
    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.

  • Patent number: 9937261
    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.

  • Publication number: 20180071253
    Abstract: The present disclosure related to a method of treating bladder cancer in a subject in need of treatment, by administering to the subject an amount of a prodrug of mitomycin C that yields a therapeutically effective amount of mitomycin C. In one embodiment, the prodrug of mitomycin C is a liposomal-prodrug of mitomycin C. In another embodiment, the liposomal-prodrug of mitomycin C is a folate-targeted liposomal-prodrug of mitomycin C.
