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.

La présente invention concerne l'administration d'agents thérapeutiques à des tissus du corps, y compris, sans en exclure d'autres, des tissus de l'oeil, pour traiter, prévenir, inhiber, retarder l'apparition ou atténuer des maladies et des troubles associés à ces tissus. L'invention concerne plus précisément des systèmes d'administration de médicaments solides et des méthodes permettant de prolonger la diffusion d'agents thérapeutiques vers lesdits tissus. Dans la présente invention, un système d'administration de médicaments solide peut être placé dans un sujet, y compris, mais exclure d'autres sites de mise en place, entre la sclérotique et la conjonctive ou à un emplacement trans-scléral. Les méthodes décrites peuvent être utilisées pour administrer de la rapamycine afin de traiter ou de prévenir l'angiogenèse, la néovascularisation choroïdienne, la dégénérescence maculaire liée à l'âge ou la dégénérescence maculaire liée à l'âge, humide, chez un sujet. Les dispositifs d'administration de médicaments solides peuvent comprendre de la rapamycine ou d'autres agents thérapeutiques. L'invention concerne également des méthodes destinées au traitement de maladies ou de troubles oculaires, consistant à administrer un agent antiprolifératif, y compris, mais sans en exclure d'autres, de la rapamycine, à proximité d'un dispositif oculaire.
