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 wet type age-related macular degeneration, comprising administering to a mammal in need thereof:
(a) a PDGF-B antagonist, wherein the PDGF-B antagonist is a pegylated aptamer having the sequence of SEQ ID NO: 23; and
(b) a VEGF antagonist, wherein the VEGF antagonist is a humanized anti-VEGF antibody or binding fragment thereof that binds to VEGF-A,
wherein the PDGF-B antagonist and the VEGF antagonist are administered simultaneously or within 90 days of each other, and wherein the PDGF-B antagonist and the VEGF antagonist are administered in an amount effective to ameliorate the wet type age-related macular degeneration, resulting in stable or improved vision in the mammal, and wherein the mammal is a human or mouse.
2. The method of claim 1 , wherein the PDGF-B antagonist and the VEGF antagonist are administered within 10 days of each other.
3. The method of claim 1 , wherein the PDGF-B antagonist and the VEGF antagonist are administered within 5 days of each other.
4. The method of claim 1 , wherein the PDGF-B antagonist and the VEGF antagonist are administered within 24 hours of each other.
5. The method of claim 1 , wherein the PDGF-B antagonist and the VEGF antagonist are administered simultaneously.
6. The method of claim 1 , wherein the PDGF-B antagonist and VEGF antagonist are administered separately in individual dosage amounts.
7. The method of claim 1 , wherein the PDGF-B antagonist and VEGF antagonist are administered together in the same composition.
8. The method of claim 1 , wherein the mammal is a human.
9. The method of any preceding claim, wherein the VEGF antagonist is a humanized anti-VEGF antibody binding fragment comprising a light chain variable domain comprising the amino acid sequence of SEQ ID NO: 25 and a heavy chain variable domain comprising the amino acid sequence of SEQ ID NO: 24.
