Methods for treating glaucoma or ocular hypertension comprising delivery of prostaglandins to the vitreous humour
This disclosure relates to a drug delivery system comprising an intraocular pressure lowering agent, a neurotrophic agent, such as a CNTF compound, a C-type Natriuretic Peptide (CNP) compound, a Tie-2 agonist, a Natriuretic Peptide Receptor-B (NPR-B) compound, or an apoptosis signaling fragment inhibitor (FAS) or FAS-ligand (FASL) inhibitor, including any combination of these compounds and a sustained delivery component. Methods of treating a glaucoma or related conditions, medicaments, kits, uses and methods of manufacturing are also described.
1. A method of treating a glaucoma or ocular hypertension comprising implanting a drug delivery system comprising a prostaglandin compound and a sustained delivery component, into a vitreous humour of an eye of a human being in need thereof, wherein the entire drug delivery system is biodegradable or bioerodible, wherein administering the drug delivery system to the vitreous humour of the eye of the human being results in a reduction in the intraocular pressure of the eye of the human being for at least one month with a risk of cystoid macular edema that is sufficiently low to be clinically acceptable, wherein the drug delivery system provides, to the vitreous humour of the eye of the human being, a dose of about 4 μg to about 40 μg of the prostaglandin compound over a period of four weeks.
2. The method of claim 1 , wherein the drug delivery system further comprises Peptide 6, Peptide 21, or contains the amino acid sequence YLGA.
3. The method of claim 1 , wherein the prostaglandin compound is bimatoprost amide, bimatoprost acid or a salt thereof.
4. The method of claim 1 , wherein the drug delivery system further comprises MET4-8.
5. The method of claim 1 , wherein the drug delivery system further comprises a peptide comprising the amino acid sequence DGGL (SEQ ID NO: 20) or a salt thereof.
6. The method of claim 1 , wherein the reduction in the intraocular pressure in the eye of the human being occurs for a period of at least 3 months after the drug delivery system is implanted into vitreous of the eye of the human being.
7. The method of claim 1 , wherein the drug delivery system is implanted into vitreous of the eye of the human being every 1 to 3 months.
8. The method of claim 1 , wherein the drug delivery system is implanted into vitreous of the eye of the human being every 3 to 6 months.
9. The method of claim 1 , wherein the drug delivery system is implanted into vitreous of the eye of the human being every 6 to 12 months.
10. The method of claim 1 , wherein the drug delivery system is implanted into vitreous of the eye of the human being every 12 to 24 months.
11. The method of claim 1 , wherein the drug delivery system has a mass of about 10 μg to about 100 mg.
12. The method of claim 1 , wherein the drug delivery system has a mass of about 10 μg to about 100 μg.
13. The method of claim 1 , wherein the drug delivery system has a mass of about 100 μg to about 1 mg.
14. The method of claim 1 , wherein the drug delivery system has a mass of about 1 mg to about 100 mg.
15. The method of claim 1 , wherein the drug delivery system contains about 1% to about 10% of the prostaglandin compound by weight.
16. The method of claim 1 , wherein the drug delivery system contains about 10% to about 20% of the prostaglandin compound by weight.
17. The method of claim 1 , wherein the drug delivery system contains about 20% to about 30% of the prostaglandin compound by weight.
18. The method of claim 1 , wherein the drug delivery system contains about 30% to about 40% of the prostaglandin compound by weight.
19. The method of claim 1 , wherein the drug delivery system contains about 40% to about 50% of the prostaglandin compound by weight.
