AGE-RELATED MACULAR DEGENERATION (AMD), PROLIFERATIVE DIABETIC RETINOPATHY (PDR) AND DIABETIC MACULAR EDEMA (DME) are collectively characterized by VEGF mediated retinal leakage, angiogenesis, and an underlying inflammatory process. TargeGen's TG100801 is designed to inhibit a select group of kinases involved in those three processes. Currently approved drug based therapy for macular degeneration requires repeated injection into the eye. TG100801 is the first topically applied, VEGFR)/Src kinase inhibitor to advance into the clinic for the treatment of Age-related macular degeneration, diabetic retinopathy. The formation of new blood vessels (angiogenesis), blood vessel leakage, and inflammation contribute to the progression of the eye disease, which is the leading cause of irreversible, severe loss of vision in people 55 years of age and older in the developed world. In cell based assays, following topical instillation, TG100572, the active drug produced by conversion of TG100801 as it penetrates the eye, was shown to induce apoptosis in proliferating endothelial cells responsible for neovasculariztion and to inhibit inflammatory-mediated processes as measured by endotoxin-induced nitric oxide release in vitro.
