selectively destroy pathologic neovascular blood vessels. Such cells include choroidal neovascularization (CNV) associated with wet age-related macular degeneration (wet AMD) and TF-expressing cancer cells and tumor-associated pathologic blood vessels (PBV). In addition to this cell-mediated cytotoxicity, hI-con1 may also interrupt the positive feedback loop between tissue factor and vascular endothelial growth factor (VEGF), thereby reducing VEGF levels. Phase 1 studies with hl-con1 are complete and no dose limited toxicities were observed. Evidence of dose-related biologic activity was observed.
