Drug delivery systems for treatment of diseases or conditions
First Claim
1. A solid drug delivery system comprising rapamycin, and wherein the solid drug delivery system when placed between the sclera and conjunctiva of a rabbit eye delivers an amount of rapamycin with a delivery profile selected from the group consisting of (a) the rapamycin is delivered in an amount sufficient to achieve, for a period of time of at least 90 days following administration of the solid drug delivery system, an average concentration of rapamycin in the vitreous of the rabbit eye of at least 0.01 ng/ml;
- and (b) the rapamycin is delivered in an amount sufficient to achieve, for a period of time of at least 90 days following administration of the solid drug delivery system, an average concentration of rapamycin in the retina choroid of the rabbit eye of at least 1 pg/mg.

Abstract
Diseases and conditions associated with tissues of the body, including but not limited to tissues in the eye, can be effectively treated, prevented, inhibited, onset delayed, or regression caused by administering therapeutic agents to those tissues. Described herein are solid drug delivery systems and methods for providing extended delivery of therapeutic agents to such tissues. A solid drug delivery system may be placed in a subject, including but not limited to placement between the sclera and the conjunctiva or transscleral placement. Described methods may be used to administer rapamycin to treat or prevent angiogenesis, choroidal neovascularization, age-related macular degeneration, or wet age-related macular degeneration in a subject. The solid drug delivery devices may comprise rapamycin or other therapeutic agents. Also described are methods of treating ocular diseases or disorders by administering an antiproliferative agent, including but not limited to rapamycin, proximal to an ocular device.

4. A solid drug delivery system comprising a therapeutic agent, wherein the solid drug delivery system when placed between the sclera and conjunctiva of a rabbit eye delivers an amount of the therapeutic agent with a delivery profile selected from the group consisting of
(a) the the therapeutic agent is delivered in an amount sufficient to achieve, for a period of time of at least 90 days following administration of the solid drug delivery system, an average concentration of the therapeutic agent in the vitreous of the rabbit eye equivalent to a rapamycin concentration of at least 0.01 ng/ml; - and
(b) the the therapeutic agent is delivered in an amount sufficient to achieve, for a period of time of at least 90 days following administration of the solid drug delivery system, an average concentration of the therapeutic agent in the retina choroid of the rabbit eye equivalent to a rapamycin concentration of at least 1 pg/mg. - View Dependent Claims (5, 6, 7, 9, 10)
