  • Patent number: 10849893
    Abstract: The present disclosure provides pharmaceutical combinations of orally administered docetaxel and a P-gp inhibitor. The pharmaceutical combinations are suitable for the treatment of cancer in a subject and for reducing or preventing toxicity, hypersensitivity-type infusion reactions, and other negative outcomes resulting from or associated with intravenously administered docetaxel (e.g., Taxotere® or docetaxel formulated with polysorbate 80) therapy in a subject suffering from cancer.

  • Patent number: 10835511
    Abstract: A pharmaceutical composition comprises a taxane (e.g., paclitaxel, docetaxel, cabazitaxel, larotaxel, ortataxel, and/or tesetaxel) in a mixture of first and second surfactants. The absorption of the taxane is increased from the pharmaceutical composition is greater than the sum of the absorption of docetaxel from either the first or the second surfactant. The increase in absorption is especially enhanced when the ratio of the first surfactant to the second surfactant in the pharmaceutical composition is between 60:40 and 85:15 by weight, and the total surfactant weight does not exceed 98% of the total weight. Polysorbate 80, polysorbate 20, and caprylocaproyl polyoxylglycerides serve as suitable first surfactants, and polysorbate 80 or polyethyoxylated castor oil serve as suitable second surfactants. The stability of the pharmaceutical composition may be enhanced by further including a stabilizer (e.g., citric acid and/or ascorbic acid).

  • Publication number: 20200338032
    Abstract: AM580 and structurally related compounds have been found to be useful in treating infection by a wide range of RNA and DNA viruses, and also in reducing associated inflammation. This activity is independent of RAR-? signaling, and is not a result of activation of the hosts innate immune response.

  • Publication number: 20190358326
    Abstract: Enteroviruses, such as EV-A71, have been found to utilize hWARS as a cell surface receptor, with expression ofhWARS rendering cells susceptible to enteroviral infection. Reduction in hWARS cell surface activity reduces susceptibility to enteroviral infection and provides a mode for treatment or prevention of enteroviral infection and its sequelae. Similarly, expression of hWARS in cultured cells and animal models provides models for understanding enteroviral disease mechanisms and the development of vaccines and/or pharmaceuticals for preventing or treating enteroviral disease.
