ALAMEDA, Calif.--([ BUSINESS WIRE ])--InSite Vision Incorporated (OTCBB:INSV) today announced the selection of Quintiles as the contract research organization to manage the DOUBle Phase 3 clinical trial of AzaSite Plus (ISV-502) and DexaSite (ISV-305) for the treatment of blepharitis. Quintiles is the worlda�s only fully-integrated pharmaceutical services organization offering clinical, commercial, consulting and capital solutions worldwide.

aWe are very pleased to partner with Quintiles for our pending DOUBle Phase 3 clinical trial. Quintilesa� extensive track record in facilitating the development and commercialization of best-selling drugs significantly reduces execution risks, while providing InSite with access to a wealth of potential services that we may utilize in the future,a said Timothy Ruane, Chief Executive Officer of InSite Vision.

In May 2011, InSite Vision obtained a Special Protocol Assessment (SPA) from the U.S. Food and Drug Administration (FDA) for the DOUBle Phase 3 Clinical Trial of AzaSite Plus and DexaSite for the treatment of blepharitis. Both product candidates are formulated with the companya�s proprietary DuraSite^� drug delivery platform: AzaSite Plus combines dexamethasone 0.1% with the antibiotic AzaSite^� (azithromycin 1% ophthalmic solution) in DuraSite and DexaSite combines dexamethasone 0.1% with DuraSite. The DOUBle (Dual Ophthalmic agents Used in Blepharitis) study will seek to enroll approximately 900 patients suffering from moderate-to-severe blepharitis in a four-arm trial designed to evaluate both product candidates simultaneously.

Blepharitis, also known as lid margin disease, is a very common eye disease in the United States and internationally. Characterized by inflammation of the eyelid, blepharitis is a chronic and recurring condition for which there is currently no FDA-approved treatment.
