摘要:
Biocompatible intraocular drug delivery systems include a non-neurotoxic macromolecule therapeutic agent and a polymeric component in the form of an implant, a microparticle, a plurality of implants or microparticles, and combinations thereof. The macromolecule therapeutic agent is released in a biologically active form, for example, the therapeutic agent may retain its three dimensional structure when released into an eye of a patient, or the therapeutic agent may have an altered three dimensional structure but retain its therapeutic activity. The therapeutic agent may be selected from the group consisting of anti-angiogenesis agents, ocular hemorrhage treatment agents, non-steroidal anti-inflammatory agents, growth factor inhibitors (such as VEGF inhibitors), growth factors, cytokines, antibodies, oligonucleotide aptamers, siRNA molecules and antibiotics. The implants may be placed in an eye to treat or reduce the occurrence of one or more ocular conditions, such as retinal damage, including glaucoma and proliferative vitreoretinopathy among others.

摘要:
Biocompatible intraocular implants include a tyrosine kinase inhibitor and a biodegradable polymer that is effective to facilitate release of the tyrosine kinase inhibitor into the vitreous of an eye for an extended period of time. The therapeutic agents of the implants may be associated with a biodegradable polymer matrix, such as a matrix that is substantially free of a polyvinyl alcohol. The implants can be placed in an eye to treat or reduce the occurrence of one or more ocular conditions, such as posterior ocular conditions.

Biocompatible intraocular implants include an anti-excitotoxic agent and a biodegradable polymer that is effective to facilitate release of the anti-excitotoxic agent into an eye for an extended period of time. The therapeutic agents of the implants may be associated with a biodegradable polymer matrix, such as a matrix that is substantially free of a polyvinyl alcohol. The implants may be placed in an eye to treat or reduce the occurrence of one or more ocular conditions, such as retinal damage, including glaucoma and proliferative vitreoretinopathy.
摘要:
Biocompatible intraocular implants include an alpha-2 adrenergic receptor agonist and a polymer associated with the alpha-2 adrenergic receptor agonist to facilitate release of the alpha-2 adrenergic receptor agonist into an eye for an extended period of time. The alpha-2 adrenergic receptor agonist may be associated with a biodegradable polymer matrix, such as a matrix of a two biodegradable polymers. The implants can be placed in an eye to treat one or more ocular conditions, such as an ocular vasculopathy or glaucoma, including reduction of an elevated intraocular pressure.

Compositions, and methods of using such compositions, useful for injection into the posterior segments of human or animal eyes are provided. Such compositions include small particles of a poorly soluble therapeutic agent that facilitates formation of concentrated regions of the therapeutic agent in the retinal pigmented epithelium of an eye. The particles are formed by combining a therapeutic agent with an ophthalmically acceptable polymer component. The particles have sizes less than about 3000 nanometers, and in some cases, less than about 200 nanometers. One example of a composition includes particles of triamcinolone acetonide and hyaluronic acid have a size less than about 3000 nanometers.

摘要:
The present invention relates to drug delivery systems comprising ocular implant, which include organic molecules, capable of modulating tyrosine kinase signal transduction in order to regulate, modulate and/or inhibit abnormal cell proliferation, in combination with a polymer, which polymer serves to control, modify, modulate and/or slow the release of the therapeutic component into the environment of the eye in which said composite is placed.

This invention relates to the sterilization of polymeric material by irradiation for use in a body of a mammal. We have surprisingly discovered that the sterilization of polymeric materials for use in a mammal by irradiation is improved by reducing the temperature at which the irradiation is carried out. One aspect of this invention relates to a sterilized polymeric material for use in a body of a mammal wherein said polymeric material is sterilized by irradiation at a reduced temperature Another aspect of this invention relates to methods of sustained delivery of a therapeutically active agent to a mammal by using a polymeric material that has been sterilized at a reduced temperature by irradiation.
