Micronized device for the delivery of biologically active molecules and methods of use thereof

1. A method for delivering a biologically active molecule to the eye, the method comprising implanting at least one micronized device for delivery of a therapeutic dose of a biologically active molecule to the eye comprising a capsule into the eye or surrounding the eye and allowing said biologically active molecule to diffuse from the device into the vitreous, the aqueous humor, or the periocular space of the eye, wherein the capsule comprises:

a) a core comprising between about 5×10 2 and 90×10 3 living cells that produce a biologically active molecule, wherein the biologically active molecule is selected from the group consisting of antiangiogenic factors, anti-inflammatory factors, neurotrophic factors, growth factors, trophic factors, antibodies and antibody fragments, neurotransmitters, hormones, cytokines, and lymphokines, wherein the core has a volume of less than 0.5 μl, and wherein the core further comprises a substantially non-degradable filamentous cell-supporting matrix, wherein the matrix comprises a plurality of monofilaments, wherein said monofilaments are twisted into a yarn or woven into a mesh or twisted into a yarn that is in non-woven strands,

and wherein the cells are distributed thereon, and

b) a biocompatible jacket surrounding said core, the jacket having a molecular weight cutoff permitting diffusion of the biologically active molecule into the eye,

wherein the device is configured as a cylinder with an outer diameter of between 200 and 350 μm and a length of between 0.5 and 6 mm, wherein the therapeutic dosage of the biologically active molecule that diffuses into the eye is between 0.1 pg and 1000 ng per eye per patient per day for a period greater than three months.

2. The method of claim 1 , wherein the biologically active molecule is selected from the group consisting of TGFβ, GDNF, NGF, CNTF, bFGF, aFGF, IL-1β, IFN-β, IFN-α, BDNF, LIF, NT-4, NTN, NT4/5, CT-1, lens epithelium-derived growth factor (LEDGF), Neublastin, modified CNTF (AXOKINE®), IL-23, rod-derived cone viability factor (RdCVF), IL-10, Alpha INF, IL-1Rα, an antibody against tumor necrosis factor (REMICADE®), vasculostatin, angiostatin, endostatin, anti-integrins, vascular endothelial growth factor inhibitors (VEGF-inhibitors), platelet factor 4, heparinase, bFGF-binding molecules, the VEGF receptor Flt, the VEGF receptor Flk, an antibody against VEGF (LUCENTIS®), soluble VEGF Receptors, and PEDF.

3. The method of claim 1 , wherein said at least one micronized device is implanted using a syringe.

4. A method for treating ophthalmic disorders in a patient suffering there from, comprising implanting a micronized device for delivery of a therapeutic dose of a biologically active molecule to the eye comprising a capsule into an eye of the patient, wherein the capsule comprises:

a) a core comprising between about 5×10 2 and 90×10 3 living cells that produce a biologically active molecule, wherein the biologically active molecule is selected from the group consisting of CNTF and IL-10, wherein the core has a volume of less than 0.5 μl, wherein said monofilaments are twisted into a yarn or woven into a mesh or twisted into a yarn that is in non-woven strands, and wherein the cells are distributed thereon and

b) a biocompatible jacket surrounding said core, the jacket having a molecular weight cutoff permitting diffusion of the biologically active molecule into the eye,

wherein the device is configured as a cylinder with an outer diameter of between 200 and 350 μm and a length of between 0.5 and 6 mm, wherein the therapeutic dosage of the biologically active molecule that diffuses into the eye is between 0.1 pg and 1000 ng per eye per patient per day for a period greater than three months, and wherein the ophthalmic disorder is selected from the group consisting of retinitis pigmentosa and experimental autoimmune uveoretinitis (EAU).
