VEGF-A as an inhibitor of angiogenesis and methods of using same
View Patent ↗The invention relates to methods and compositions for the treatment or prevention of ocular angiogenesis and neovascularization associated with neovascular disease. Administration of vascular endothelial growth factor (VEGF)-A into the eye when macrophage infiltration is reduced inhibits ocular angiogenesis.
1. An ophthalmic composition for treatment of ocular neovascularization comprising an effective amount of a SPARC antagonist, a compound selected from VEGF-A, PLGF-1 and PLGF-2, and a pharmaceutically acceptable carrier suitable for injection into the eye or topical application to the eye, wherein said composition inhibits ocular neovascularization.
2. The composition of claim 1 wherein the SPARC antagonist is an antibody to SPARC or antibody fragment that binds to SPARC.
3. The composition of claim 1 wherein the SPARC antagonist is siRNA that binds to and inhibits expression of the SPARC gene.
4. The composition of claim 1 wherein the SPARC antagonist is a peptide that binds to and inhibits the active site of SPARC.
