“InSite Vision made outstanding progress on every clinical-stage product in our pipeline during the first quarter. Among many achievements, we reported positive top-line results from our Phase 1/2 clinical trial of ISV-303 for post-surgical ocular pain and inflammation. We continue to make significant progress towards achieving an SPA for AzaSite Plus and DexaSite, promptly responding to minor recommendations from the FDA, for a Phase 3 protocol evaluating both AzaSite Plus and DexaSite in blepharitis. InSite also filed an IND for ISV-101 for use in dry eye disease,” said Timothy Ruane, InSite’s Chief Executive Officer. “With three products now in Phase 3 development, InSite is demonstrating our strong commitment to rapid and strategic execution in clinical and regulatory development.”
