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 macular edema following retinal vein occlusion in a patient in need thereof comprising administering to the patient, by intravitreal injection, a single initial dose of 2 mg aflibercept, followed by five secondary doses of 2 mg aflibercept, followed by one or more tertiary doses of 2 mg of aflibercept;
wherein each secondary dose is administered to the patient approximately 4 weeks following the immediately preceding dose;
wherein each tertiary dose is administered on an as needed or pro re nata (PRN) basis, based on visual or anatomic outcomes as assessed by a qualified medical professional; and
wherein the patient achieves a gain in visual acuity of at least 15 letters, compared to baseline by 52 weeks following the initial dose, as measured by the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart.
2. The method of claim 1 , wherein the patient achieves the gain by 24 weeks following the initial dose.
3. The method of claim 1 , wherein the patient achieves a gain of at least 10 letters, compared to baseline by week 24, as measured by the ETDRS visual acuity chart.
4. The method of claim 1 , wherein the patient achieves a gain of at least 5 letters, compared to baseline by week 24, as measured by the ETDRS visual acuity chart.
5. The method of claim 1 , wherein each tertiary dose is administered on an as needed or pro re nata (PRN) basis, based on visual and anatomic outcomes as assessed by a qualified medical professional.
6. The method of claim 1 , wherein each tertiary dose is administered on an as needed or pro re nata (PRN) basis, based on visual outcomes as assessed by a qualified medical professional.
7. The method of claim 1 , wherein each tertiary dose is administered on an as needed or pro re nata (PRN) basis, based on anatomic outcomes as assessed by a qualified medical professional.
8. The method of claim 1 , wherein the qualified medical professional is a physician.
9. A method for treating macular edema following retinal vein occlusion in a patient in need thereof comprising administering to the patient, by intravitreal injection, a single initial dose of 2 mg aflibercept, followed by one or more secondary doses of 2 mg aflibercept, followed by one or more tertiary doses of 2 mg of aflibercept;
wherein each secondary dose is administered to the patient approximately 4 weeks following the immediately preceding dose;
wherein each tertiary dose is administered on an as needed or pro re nata (PRN) basis, based on visual or anatomic outcomes as assessed by a qualified medical professional; and
wherein the patient achieves a reduction in central retinal thickness of at least 400 micrometers as measured by optical coherence tomography compared to baseline by 52 weeks following the initial dose.
10. The method of claim 9 , wherein the patient achieves the reduction in central retinal thickness by 24 weeks following the initial dose.
11. The method of claim 9 , wherein five secondary doses are administered following the initial dose.
12. The method of claim 9 , wherein each tertiary dose is administered on an as needed or pro re nata (PRN) basis, based on visual and anatomic outcomes as assessed by a qualified medical professional.
13. The method of claim 9 , wherein each tertiary dose is administered on an as needed or pro re nata (PRN) basis, based on visual outcomes as assessed by a qualified medical professional.
14. The method of claim 9 , wherein each tertiary dose is administered on an as needed or pro re nata (PRN) basis, based on anatomic outcomes as assessed by a qualified medical professional.
15. The method of claim 9 , wherein the qualified medical professional is a physician.
16. A method for treating macular edema following retinal vein occlusion in a patient in need thereof comprising sequentially administering to the patient, by intravitreal injection, a single initial dose of 2 mg aflibercept, followed by five secondary doses of 2 mg of aflibercept, followed by one or more tertiary doses of 2 mg of aflibercept;
wherein each secondary dose is administered at least 4 weeks following the immediately preceding dose;
wherein each tertiary dose is administered on an as needed or pro re nata (PRN) basis, based on visual or anatomic outcomes as assessed by a qualified medical professional; and
wherein the method for treating macular edema following retinal vein occlusion results in at least 55 percent of patients achieving an average gain in visual acuity of at least 15 letters, compared to baseline by 52 weeks following the initial dose, as measured by the Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity chart.
17. The method of claim 16 , wherein the method results in at least 55 percent of the patients achieving the gain by 24 weeks following the initial dose.
18. The method of claim 16 , wherein the method results in at least 55 percent of the patients achieving a gain of at least 10 letters, compared to baseline by week 24, as measured by the ETDRS visual acuity chart.
19. The method of claim 16 , wherein the method results in at least 55 percent of the patients achieving a gain of at least 5 letters, compared to baseline by week 24, as measured by the ETDRS visual acuity chart.
20. The method of claim 16 , wherein each tertiary dose is administered on an as needed or pro re nata (PRN) basis, based on visual and anatomic outcomes as assessed by a qualified medical professional.
21. The method of claim 16 , wherein each tertiary dose is administered on an as needed or pro re nata (PRN) basis, based on visual outcomes as assessed by a qualified medical professional.
22. The method of claim 16 , wherein each tertiary dose is administered on an as needed or pro re nata (PRN) basis, based on anatomic outcomes as assessed by a qualified medical professional.
23. The method of claim 16 , wherein the qualified medical professional is a physician.
