  • Publication number: 20090004273
    Abstract: Polymeric devices for controlled release of an active agent of interest are provided. The active agent is provided within a biodegradable polymer system to supply a polymeric device for controlled release of the active agent. The polymer system is a copolymer or a polymer blend comprising a hydrophobic component and a hydrophilic component, and the polymer system does not form a hydrogel when contacted with, or immersed in an aqueous system, for example when the device is implanted in a subject. When the device is administered to a subject, for example, when it is implanted, the device releases the active agent in a controlled fashion without a lag period, or with a minimal lag period. Methods for producing the polymeric devices are also provided, as are methods of using the polymeric devices to provide for controlled release of an active agent in a subject.

  • Publication number: 20080254086
    Abstract: Controlled release compositions for controlling release of a GnRH molecule or a GnRH analog are provided. The compositions include a GnRH molecule or GnRH analog as an active agent, and a controlled release component for controlling release of the GnRH molecule or GnRH analog from the composition. The compositions provide a sustained mean steady state plasma concentration (Css) of the active agent of at least about 1.5 ng/mL for a period of at least about 48 hours when the composition is administered to a subject. In addition, the use of a controlled release component in the manufacture of a composition for the controlled release of a GnRH molecule or GnRH analog is provided. The controlled release component is capable of providing a sustained mean steady state plasma concentration (Css) of the active agent of at least about 1.5 ng/mL for a period of at least about 48 hours when the manufactured composition is administered to a subject.

  • Publication number: 20080166391
    Abstract: A coaxial implant has been developed using entirely biodegradable polymeric materials. As referred to herein, a coaxial implant is a device having a core containing drug, surrounded by a semi-permeable membrane that controls the rate of release of material from the core. The device is formed by extrusion, using a pre-milling and extruding step to maximize uniformity of drug dispersion within the polymeric material. In one embodiment, the polymer is processed to yield a semi-crystalline polymer, rather than an amorphous polymer. The core containing the drug and the polymer membrane(s) can be the same or different polymer. The polymer can be the same or different composition (i.e., both polycaprolactone, or both poly(lactide-co-glycolide) of different monomer ratios, or polycaprolactone outside of a core of poly(lactide)), of the same or different molecular weights, and of the same or different chemical structure (i.e., crystalline, semi-crystalline or amorphous).

  • Publication number: 20080152708
    Abstract: The present invention relates to novel nonpolymeric compounds and compositions that form liquid, high viscosity materials suitable for the delivery of biologically active substances in a controlled fashion, and for use as medical or surgical devices. The materials can optionally be diluted with a solvent to form a material of lower viscosity, rendering the material easy to administer. This solvent may be water insoluble or water soluble, where the water soluble solvent rapidly diffuses or migrates away from the material in vivo, leaving a higher viscosity liquid material.

  • Patent number: 6931378
    Abstract: Methods and systems for collecting, managing, distributing and updating geophysical data primarily for E&P companies include in one embodiment the sale of subscriptions entitling paid subscribers access to all subscribed data including both preview and full data. Initial and subsequent data providers are preferably compensated from subscriber fees and may be compensated based on relative subscriber use of data. Data subscriptions can include for subscribers the right to vote or otherwise provide input relating to desired data updates. Data updates are preferably purchased based on competitive bids. The inventive systems and methods diminish much of the risk and uncertainty associated with the collection, management, distribution and updating of geophysical data under current methodologies, making the process more efficient and cost-effective for participating parties.

  • Publication number: 20020142093
    Abstract: Processes for making microparticles, preferably containing an active agent, are provided. In a preferred embodiment, the process involves preparing (1) a dispersed phase containing an agent in a solution of polymer and a first solvent; (2) a continuous phase containing a surfactant, and a second solvent that is totally or partially immiscible with the first solvent; and (3) an extraction phase that is a nonsolvent for the polymer, a solvent for the continuous phase components, and a solvent for the first solvent, wherein the first solvent has solubility in the extraction phase of between about 0.1% and 25% by weight. Then, the dispersed phase and the continuous phase are mixed to form an emulsion, and the emulsion is then briefly mixed with a suitable quantity of extraction phase to induce skin formation at the interface of the dispersed and continuous phases. Remaining solvent is removed by an evaporation process step.
