Combination therapy for the treatment of ocular neovascular disorders
View Patent ↗The invention features methods for treating a patient diagnosed with, or at risk of developing, a neovascular disorder by administering a PDGF antagonist and a VEGF antagonist to the patient. The invention also features a pharmaceutical composition containing a PDGF antagonist and a VEGF antagonist for the treatment or prevention of a neovascular disorder.
1. A method for ameliorating age-related macular degeneration, comprising administering to a human or mouse in need thereof:
(a) a PDGFR antagonist, wherein the PDGFR antagonist is an APB5 antibody; and
(b) a VEGF antagonist, wherein the VEGF antagonist is an anti-VEGF antibody or binding fragment thereof that binds to human VEGF-A,
wherein the PDGFR antagonist and the VEGF antagonist are administered simultaneously or within 90 days of each other, and wherein the PDGFR antagonist and the VEGF antagonist are administered in an amount effective to ameliorate the age-related macular degeneration in the human or mouse.
2. The method of claim 1 , wherein the PDGFR antagonist and the VEGF antagonist are administered within 10 days of each other.
3. The method of claim 1 , wherein the PDGFR antagonist and the VEGF antagonist are administered within 5 days of each other.
4. The method of claim 1 , wherein the PDGFR antagonist and the VEGF antagonist are administered within 24 hours of each other.
5. The method of claim 1 , wherein the PDGFR antagonist and the VEGF antagonist are administered simultaneously.
6. The method of claim 1 , wherein the PDGFR antagonist is a PDGFR-beta antagonist.
7. The method of claim 1 , wherein the VEGF antagonist is 2C3.
8. The method of claim 1 , wherein the PDGFR antagonist and VEGF antagonist are formulated separately and in individual dosage amounts.
9. The method of claim 1 , wherein the PDGFR antagonist and VEGF antagonist are formulated together.
10. The method of claim 1 , wherein the anti-VEGF antibody or binding fragment thereof has (a) a heavy chain variable domain comprising the amino acid sequence of SEQ ID NO: 26 and a light chain variable domain comprising the amino acid sequence of SEQ ID NO: 27, or (b) a light chain variable domain comprising the sequence of SEQ ID NO: 25 and a heavy chain variable domain comprising the amino acid sequence of SEQ ID NO: 24.
