InSite Vision Completes Phase 3 Clinical Study of BromSite for the Reduction of Pain and Inflammation After Cataract Surgery

Last Patient Concludes Dosing and Evaluation

ALAMEDA, Calif.--(BUSINESS WIRE)-- InSite Vision Incorporated (OTCBB: INSV) today announced that the last patient has completed dosing and evaluation in the Phase 3 clinical trial of BromSite™ (ISV-303) for the reduction of pain and inflammation after cataract surgery. BromSite combines a low dose (0.075%) of the non-steroidal anti-inflammatory drug (NSAID) bromfenac with InSite Vision's DuraSite® drug delivery technology.

InSite Vision expects that top-line data from the BromSite Phase 3 clinical trial will be available in the first quarter of 2013. This study enrolled more than 240 patients undergoing cataract surgery in a two-arm trial designed to evaluate the efficacy and safety of BromSite against the DuraSite vehicle alone. Patients were randomized and then dosed twice-a-day beginning the day before surgery and continuing the day of surgery and for 14 days post-surgery. The primary study endpoint is the reduction of inflammation after surgery, with a secondary endpoint of reduction in pain. Pharm-Olam International served as the contract research organization managing the BromSite study on behalf of InSite Vision.

This is the first of two Phase 3 clinical studies in support of BromSite's regulatory submissions. The design of the second Phase 3 study for BromSite will be finalized pending full input from both the U.S. Food and Drug Administration and European regulatory authorities.

About Cataract Surgery

Cataract surgery is the most frequently performed ocular surgery in the United States with more than three million procedures annually. Typically, anti-inflammatory eye drops are prescribed to reduce pain and inflammation both before and after surgery. Anti-inflammatory eye drops are also administered as prophylaxis against cystoid macular edema, or CME. CME is a relatively rare, but extremely serious, adverse event in ocular surgery that can lead to blindness. Many physicians believe that a higher penetration of bromfenac into the ocular tissues may reduce the risk of CME. InSite intends to do additional clinical studies post-approval in pursuit of adding prevention of CME to the BromSite label.

About DuraSite®and DuraSite 2®

While eye drops are a proven delivery mechanism for numerous ocular drugs, efficacy of these agents is impeded by tears and blinking, which rinse the drug from the surface of the eye and limit retention and absorption. InSite's DuraSite and DuraSite 2 platforms are sustained delivery technologies using a synthetic polymer-based formulation designed to extend the residence time of a drug relative to conventional topical therapies. DuraSite and DuraSite 2 enable topical delivery of a solution, gel or suspension and can be customized for delivering a wide variety of potential drug candidates. The DuraSite platform is currently leveraged in two commercial products for the treatment of bacterial eye infections, AzaSite® and Besivance®. InSite Vision is advancing a portfolio of novel preclinical- to clinical-stage ophthalmic products based on the DuraSite platform and anticipates advancing future ophthalmic product candidates using the DuraSite 2 platform.

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 the frequency of treatment and improving the efficacy of topical 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 Merck, and Besivance® (besifloxacin ophthalmic suspension) 0.6%, marketed by Bausch + Lomb. InSite Vision is also advancing three novel ophthalmic therapeutics through Phase 3 clinical studies: AzaSite Plus and DexaSite for the treatment of eye infections, and BromSite™ for pain and inflammation associated with ocular surgery.
