  • Publication number: 20080020016
    Abstract: The present invention provides methods of forming a solid, biodegradable implant in-situ in a body by administering a liquid pharmaceutical composition comprising an effective amount of a biocompatible, water-insoluble, biodegradable polymer and an effective amount of a therapeutic peptide covalently modified with one or more lipophilic or amphiphilic moieties, which are dissolved or dispersed in a biocompatible, water-soluble organic solvent. This invention also provides related compositions and methods.

  • Publication number: 20070196416
    Abstract: The present invention provides for a stabilized biodegradable polymeric composition useful as a controlled release delivery system for peptide agents. The compositions of the present invention comprise a) a beneficial salt of a peptide agent formed with a strong acid that minimizes or prevents the interaction/reaction between the peptide agent and the polymer in an organic solution; b) a biodegradable polymer; c) a pharmaceutically acceptable organic solvent; and d) optionally one or more excipients. The present invention also relates to a method of manufacturing and a method of use thereof.

  • Patent number: 7085682
    Abstract: A method and system for analyzing website activity. According to an example embodiment, the system receives event-level data representing visitor session activity on a client website; attributes characteristic information of the event-level data associated with each visitor's session to at least one of a plurality of visitor segments, stores results of the attributed information aggregated according to visitor segment prior to a client-requested analysis of the event-level data, and provides online reports based on the resultant data in response to a client-requested analysis of the event-level data.

  • Publication number: 20060034923
    Abstract: The present invention provides compositions and methods for the controlled release delivery of one or more biologically active compounds to a subject. Specifically, the invention provides for a pharmaceutical composition for the controlled release delivery of biologically active compounds to a subject comprising: a) a complex of a biologically active compound having at least one basic functional group and a polyanion derived from hexahydroxycyclohexane having at least two negatively charged functional groups; and b) a pharmaceutically acceptable carrier comprising a biodegradable, water-insoluble polymer. By complexing a biologically active compound with a polyanion, the tight, stable complex may be incorporated into a long-acting dosage system having a more desired drug release curve over time than that is found in the prior art. The invention also provides the methods of making such compositions and the methods of use thereof.

  • Patent number: 5893911
    Abstract: Methods and associated structures for rapidly processing messages in a distributed computing application. Rules are stored in structures defined by the present invention and methods associated therewith rapidly process the boolean predicates of the rules to determine what actions need be taken in the distributed computing environment in response to receipt of a message published by a publishing application in the distributed computing environment. Rules argument tables store rule argument entries which each represent a single boolean predicate test clause which compare a column (field) of a published message with either a fixed value or with another column of a published message. All rule argument predicate clauses which are AND'ed to form a rule are related in the rules argument tables by a common rule.sub.-- id column value. An operations table stores entries each of which describes groups of attributes of rules stored in the rules argument tables.
