About InSite Vision

InSite Vision is advancing new ophthalmologic products for unmet eye care needs based on its innovative DuraSite platform technologies. The DuraSite® and DuraSite® 2 drug delivery systems extend the duration of drug retention on the surface of the eye, thereby reducing frequency of treatment and improving the efficacy of topically delivered drugs.

The DuraSite® platform is currently leveraged in two commercial products for the treatment of bacterial eye infections, AzaSite® (azithromycin ophthalmic solution) 1%, marketed in the U.S. by Akorn Pharmaceuticals, and Besivance® (besifloxacin ophthalmic suspension) 0.6%, marketed by Bausch & Lomb, a subsidiary of Valeant Pharmaceuticals. BromSite (ISV-303) for pain and swelling associated with ocular surgery has completed its Phase 3 clinical studies and InSite expects to file the New Drug Application for BromSite with the U.S. Food and Drug Administration in the second half of 2014. InSite Vision is also advancing two novel ophthalmic therapeutics through Phase 3 clinical studies: AzaSite Plus (ISV-502) and DexaSite (ISV-305) for the treatment of eye infections.
