Use of a VEGF antagonist to treat angiogenic eye disorders
The present invention provides methods for treating angiogenic eye disorders by sequentially administering multiple doses of a VEGF antagonist to a patient. The methods of the present invention include the administration of multiple doses of a VEGF antagonist to a patient at a frequency of once every 8 or more weeks. The methods of the present invention are useful for the treatment of angiogenic eye disorders such as age related macular degeneration, diabetic retinopathy, diabetic macular edema, central retinal vein occlusion, branch retinal vein occlusion, and corneal neovascularization.
1. A method for treating an angiogenic eye disorder in a patient, said method comprising sequentially administering to the patient a single initial dose of a VEGF antagonist, followed by one or more secondary doses of the VEGF antagonist, followed by one or more tertiary doses of the VEGF antagonist;
wherein each secondary dose is administered 4 weeks after the immediately preceding dose; and wherein each tertiary dose is administered 12 weeks after the immediately preceding dose;
wherein the VEGF antagonist is a receptor-based chimeric molecule comprising an immunoglobin-like (Ig) domain 2 of a first VEGF receptor which is Flt1 and Ig domain 3 of a second VEGF receptor which is Flk1, and a multimerizing component.
2. The method of claim 1 , wherein the VEGF antagonist is aflibercept.
3. The method of claim 1 , wherein all doses of the VEGF antagonist are administered to the patient by intraocular administration.
4. The method of claim 3 , wherein the intraocular administration is intravitreal administration.
5. The method of claim 4 , wherein all doses of the VEGF antagonist comprise from about 0.5 mg to about 2 mg of the VEGF antagonist.
6. The method of claim 5 , wherein all doses of the VEGF antagonist comprise 0.5 mg of the VEGF antagonist.
7. The method of claim 5 , wherein all doses of the VEGF antagonist comprise 2 mg of the VEGF antagonist.
8. The method of claim 5 , wherein the angiogenic eye disorder is selected from the group consisting of: age related macular degeneration, diabetic retinopathy, diabetic macular edema, central retinal vein occlusion, branch retinal vein occlusion, and corneal neovascularization.
9. The method of claim 8 wherein the angiogenic eye disorder is age related macular degeneration.
10. The method of claim 8 wherein the angiogenic eye disorder is diabetic retinopathy.
11. The method of claim 8 , wherein the angiogenic eye disorder is diabetic macular edema.
