Publication number: 20100035911Abstract: A method of treating a hyperproliferative disorder, including a cancer, in a subject in need of such treatment, comprising administering to said subject a pharmaceutical combination containing a treatment effective amount of: (a) a vitamin A derivative (i.e., a retinoid), or a pharmaceutically acceptable salt thereof, and an inhibitor of microtubule structure or function; or (b) a combination containing fenretinide (i.e., N-(4-hydrophenyl) retinamide, 4-HPR) and ABT-751 (i.e., N-[2-[(4-hydroxyphenyl)amino]-3-pyridinyl]-4-methoxybenzenesulfonamide). Vitamin A derivatives that may be useful for this invention according to (a) include, but are not limited to, all-trans-retinoic acid, 13-cis-retinoic acid, and fenretinide. Microtubule inhibitors that may be useful for this invention according to (a) include, but are not limited to, inhibitors of the Vinca binding domain (e.g., vincristine, vinblastine, vinorelbine, and cryptophycin 52), inhibitors of the Taxane domain (e.g.Type: ApplicationFiled: May 16, 2007Publication date: February 11, 2010Inventors: Barry James Maurer, C.

Patent number: 7476692Abstract: The present invention provides stable aqueous solutions consisting essentially of: (a) a sphingolipid; (b) lactic acid; and (c) optionally a stabilizing agent; wherein the solution has a molar ratio of lactic acid to sphingolipid of 1:1 to 10:1. The present invention further provides an emulsion formulation consisting essentially of: (a) lactic acid; (b) a sphingolipid, wherein the sphingolipid is present in an amount of about 0.1 to about 30 mg/ml of emulsion; (b) optionally an isotonic agent; and (c) a phospholipid present in an amount of about 0.2 to about 200 mg/ml of emulsion. Methods of making and using the compositions are also provided.Type: GrantFiled: February 19, 2004Date of Patent: January 13, 2009Assignee: Childrens Hospital Los AngelesInventors: Shanker Gupta, C.

Patent number: 7169819Abstract: A pharmaceutical composition for parenteral delivery, comprising a retinide such as fenretinide in combination with a solvent capable of dispersing or solubilizing the retinide. The solvent comprises an alcohol, such as ethanol, in combination with an alkoxylated castor oil, such as CREMOPHOR® EL, or comprising a retinide, such as fenretinide, in an emulsion composed of a lipoid dispersed in an aqueous phase, a stabilizing amount of a non-ionic surfactant, optionally a solvent, and optionally an isotonic agent. In addition, a method of use in the treatment of hyperproliferative disorders, such as cancers is described.Type: GrantFiled: December 5, 2001Date of Patent: January 30, 2007Assignee: Childrens Hospital Los AngelesInventors: Shanker Gupta, Barry J. Maurer, C. Patrick Reynolds, B. Rao Vishnuvajjala

Patent number: 6665430Abstract: A method of preparing cell samples for viable cell number quantification with a fluorescence digital imaging microscopy system employing digital thresholding technique. The cell sample is stained with a first, fluorescent dye and treated with a second dye that is able to quench the fluorescence of the first dye. The fluorescent dye accumulates in viable cells only and is used to stain the viable cells. The second dye is excluded from viable cells but enters non-viable cells, thereby quenching the background fluorescence in non-viable cells and the medium. Two examples of dye combinations are described: fluorescein diacetate used as the fluorescent dye with eosin Y as the quenching dye; and calcein-AM used as the fluorescent dye with trypan blue as the quenching dye. By reducing the background fluorescence, the dynamic range and accuracy of viable cell number measurements are enhanced.Type: GrantFiled: August 13, 2002Date of Patent: December 16, 2003Assignee: Childrens Hospital Los AngelesInventors: C.
