Patent number: 7144873Abstract: 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: GrantFiled: July 13, 2004Date of Patent: December 5, 2006Assignee: SuperGen, Inc.Inventors: Rajashree Joshi-Hangal, Xichen Zhang, Stephanie Gong, Sanjeev Redkar, Ashok Y.
