  • Patent number: 11298323
    Abstract: This invention relates to a bioerodible drug delivery device that can be implanted in a patient at or near an area in need of treatment. The bioerodible drug delivery device can be used to deliver a wide variety of different pharmaceutically active agents, and can do so at a controlled rate and over an extended period of time. The bioerodible drug delivery device includes a bioerodible polymeric outer housing with one or more delivery ports for delivering the pharmaceutically active agent(s) contained therein. The polymer used as the bioerodible polymeric outer housing is not substantially degraded during the dosing of the pharmaceutically active agent(s) in the bioerodible drug delivery device. The invention also provides methods of making the bioerodible drug delivery device and using it for the treatment of diseases and disorders.

  • Publication number: 20110224141
    Abstract: A method of treatment and/or prevention of cancer comprises administering agents which cause increased intracellular granularity in cancer cells, at least in an amount sufficient to inhibit proliferation of such cells and preferably in an amount sufficient to lead to cancer cell death. The method is particularly directed to refractory cancer, particularly hormone refractory prostate cancer. The agents identified cause increased intracellular granularity in the cancer cells, and also convert adherent cancer cells to non-adherent cancer cells, leading to cancer cell death. Using the present invention, cancer cells undergo increased intracellular granularity at relatively low agent concentrations, while also inhibiting cell proliferation. Increased concentrations lead to conversion of adherent cancer cells to non-adherent cancer cells, then to cell death.
