    Patent 8,673,341
    Issued: March 18, 2014
    Assignee(s): Allergan, Inc.

    The present invention provides a method of treating an ocular condition in an eye of a patient, comprising the step of placing a biodegradable intraocular implant in an eye of the patient, the implant comprising a prostamide and a biodegradable polymer matrix that releases drug at a rate effective to sustain release of an amount of the prostamide from the implant to provide an amount of the prostamide effective to prevent or reduce a symptom of an ocular condition of the eye, wherein said ocular condition is elevated IOP and said implant is placed in an intracameral location to dilate the outflow channels of the eye emanating from Schlemm's Canal.

Term Definition
Drug Patent A drug patent is assigned by the U.S. Patent and Trademark Office and assigns exclusive legal right to the patent holder to protect the proprietary chemical formulation. The patent assigns exclusive legal right to the inventor or patent holder, and may include entities such as the drug brand name, trademark, product dosage form, ingredient formulation, or manufacturing process A patent usually expires 20 years from the date of filing, but can be variable based on many factors, including development of new formulations of the original chemical, and patent infringement litigation.
Drug Exclusivity Exclusivity is the sole marketing rights granted by the FDA to a manufacturer upon the approval of a drug and may run simultaneously with a patent. Exclusivity periods can run from 180 days to seven years depending upon the circumstance of the exclusivity grant.
RLD A Reference Listed Drug (RLD) is an approved drug product to which new generic versions are compared to show that they are bioequivalent. A drug company seeking approval to market a generic equivalent must refer to the Reference Listed Drug in its Abbreviated New Drug Application (ANDA). By designating a single reference listed drug as the standard to which all generic versions must be shown to be bioequivalent, FDA hopes to avoid possible significant variations among generic drugs and their brand name counterpart.
