  • Publication number: 20170252447
    Abstract: A novel treatment for dialysis patients needing a hemodialysis graft by providing a therapeutic formulation that can be infused to such patients, which may mitigate graft-related neointimal hyperplasia, thrombosis, and/or related mechanisms of graft failure. The therapeutic formulation may include sirolimus and/or other olimus drug(s). The therapeutic formulation may be infusible and stable in solution for such a pharmaceutical and therapeutic purpose. The therapeutic formulation may have a pharmaceutically acceptable shelf life such that the pharmaceutical agent remains chemically stable (e.g., does not precipitate) for a suitable number of days (e.g., at least 30 days, at least 60 days, at least 90 days, etc.) at 37° C. The therapeutic formulation may be suitable for application to a patient's blood vessel/vascular graft via an infusion pump. For instance, the therapeutic formulation may be suitable for application to the patient's hemodialysis graft location.

  • Patent number: 7316911
    Abstract: A method is provided for the localized intravascular administration of a fibrinolytic metalloproteinase to a human subject in amounts that are both safe and effective to lyse an occluding fibrin-containing blood clot, while also avoiding the neutralizing effects of ?2-macroglobulin in the circulating blood. A method is also provided for the treatment of a blood clot in, around or attached to an indwelling vascular access device. A method for restoring patency and function of an indwelling vascular access device is also provided.

  • Patent number: 6028244
    Abstract: The invention provides a nonhuman transgenic animal having a transgene disrupting or interfering with expression of G.alpha..sub.q chromosomally integrated into the germ cells of the animal. Cells and cell lines derived from these nonhuman transgenic animals; a method for producing a transgenic nonhuman animal having a phenotype characterized by expression of a transgene which is otherwise not naturally occurring, where the expression of the transgene disrupts or interferes with G.alpha..sub.q activity; a method for determining an effect of an agent on G.alpha..sub.q expression, by administering an effective amount of the agent to a transgenic nonhuman animal having a transgene disrupting or interfering with G.alpha..sub.q, and measuring a physiological response of the transgenic nonhuman animal to the agent, and comparing the physiological response of the transgenic nonhuman animal having a transgene disrupting or interfering with G.alpha..sub.q to a control animal is also provided.
