  • Patent number: 7144873
    Abstract: Pharmaceutical formulations, kits and vessels are provided for delivering decitabine to a patient suffering from a disease in need of treatment with decitabine. The pharmaceutical formulation comprises decitabine solvated in a non-aqueous solvent that comprises glycerin, propylene glycol, polyethylene glycol, or combinations. Such formulations are more chemically stable than conventional liquid formulations of decitabine containing more than 40% water in volume. The pharmaceutical formulations can be used for any disease that is sensitive to the treatment with decitabine, such as hematological disorders and cancer.
    Type: Grant
    Filed: July 13, 2004
    Date of Patent: December 5, 2006
    Assignee: SuperGen, Inc.
    Inventors: Rajashree Joshi-Hangal, Xichen Zhang, Stephanie Gong, Sanjeev Redkar, Ashok Y. Gore

  • Publication number: 20050042293
    Abstract: Biodegradable polymeric implants can provide a safe and efficient means to deliver drugs in the treatment of various diseases. Although a polymeric drug delivery system can be implanted as a solid device within a subject, it is also possible to administer such a system as an injectable liquid which solidifies in vivo. An improved formulation of a polymeric drug delivery system comprises a water insoluble copolymer that is a solid or wax at 37° C., a water soluble polymer that is a liquid at 25° C., and a hydrophobic drug. These drug delivery systems can be administered by injection, and do not require the use of a toxic curing agent or inconvenient temperature manipulations.
