    摘要: A method and devices for localized delivery of a chemotherapeutic agent to solid tumors, wherein the agent does not cross the blood-brain barrier and is characterized by poor bioavailability and/or short half-lives in vivo, are described. The devices consist of reservoirs which release drug over an extended period while at the same time preserving the bioactivity and bioavailability of the agent. In the most preferred embodiment, the device consists of biodegradable polymeric matrixes, although reservoirs can also be formulated from non-biodegradable polymers or reservoirs connected to implanted infusion pumps. The devices are implanted within or immediately adjacent the tumors to be treated or the site where they have been surgically removed.

The devices are implanted within or immediately adjacent the tumors to be treated or the site where they have been surgically removed. The examples demonstrate the efficacy of paclitaxel and camptothecin delivered in polymeric implants prepared by compression molding of biodegradable and non-biodegradable polymers, respectively. The results are highly statistically significant.

    摘要: The additive effect of combined intracranial carmustine (“BCNU”) with intracranial temozolomide (“TMZ”), and particularly in combination with radiation (“XRT”), in the treatment of two rat intracranial glioma models, the 9L gliosarcoma and the F98 glioma, demonstrates that local delivery of both drugs, especially in combination with radiation, is far more effective than delivery of either drug alone or one systemically and one locally, either with or without radiation. The triple therapy showed a significant improvement in survival when compared to controls (p=0.0004), local BCNU (p=0.0043), oral TMZ (p=0.0026), local TMZ (p=0.0105), and the combinations of either BCNU and XRT (p=0.0378) or oral TMZ and local BCNU (p=0.0154).

    摘要: Localized delivery of 1,25 D3 directly to a target area using biodegradable polymeric matrices maximizes the efficacy of this drug while minimizing systemic exposure and toxicity. Anticalcemic analogs of 1,25 D3 have also been incorporated into controlled release polymer formulations to achieve efficacious intracranial concentrations of 1,25 D3 analogs for the treatment of intracranial tumors as well as neurodegenerative disorders such as Alzheimer's disease as well as to maximize the efficacy of these analogs in the treatment of systemic malignancies. The therapeutic efficacy of these formulations was demonstrated through a variety of studies in vitro and in vivo. Hybrid analogs of 1,25 D3 were incorporated into biodegradable polymer wafers composed of a polyanhydride copolymer of 1,3-bis(p-carboxyphenoxy)propane (CPP) and sebacic acid (SA) in a 20:80 molar ratio. In addition to providing improved treatments for malignancies and neurodegenerative disorders, the spatial localization and high reproducibility of this controlled delivery methodology presents a unique opportunity to study in vivo the poorly understood mechanisms of 1,25 D3's antiangiogenic, antiproliferative, and transcriptional regulating activities.
