ISTA Pharmaceuticals, Inc. (ISTA) Highlights PROLENSA(TM) Clinical Data at the 2012 American Society of Cataract & Refractive Surgery Symposium and Congress


4/23/2012 9:23:49 AM

IRVINE, CA--(Marketwire - April 23, 2012) - ISTA Pharmaceuticals, Inc. (NASDAQ: ISTA), today presented results from one of two Phase 3 studies of PROLENSA (bromfenac ophthalmic solution), the Company's once-daily topical nonsteroidal anti-inflammatory product candidate for the treatment of ocular inflammation and pain following cataract surgery. The findings showed PROLENSA was statistically greater than placebo in clearing subjects' ocular inflammation by Day 15 and eliminating ocular pain one day post-surgery, the study's primary and secondary endpoints, respectively. These data were presented in a poster session at the 2012 American Society of Cataract and Refractive Surgery (ASCRS) Symposium and Congress being held from April 20 to 24, 2012, in Chicago, IL. The Company intends to file a New Drug Application (NDA) with the U.S. Food and Drug Administration (FDA) for PROLENSA in the first half of 2012.

Additional data from the poster presentation, titled "Phase III Clinical Trial of Low Concentration Bromfenac Ophthalmic Solution Dosed Once Daily for Postoperative Ocular Inflammation and Pain", demonstrated there were no serious drug-related ocular or systemic adverse events, and PROLENSA's safety profile was consistent with ISTA's currently marketed once-daily topical nonsteroidal anti-inflammatory (NSAID) compound, BROMDAY (bromfenac ophthalmic solution) 0.09%.

Authors of the poster were Sharon Klier, MD, MPH; Thomas R. Walters, MD; John M. Lim, MD; James A. Gow, MD; Timothy R. McNamara, PharmD.

ABOUT THE PHASE 3 PROGRAM
ISTA conducted two Phase 3 multi-center, randomized, double-masked, parallel-group controlled studies. Data were collected under a common protocol and conducted and analyzed as two independent studies in the U.S. Each study enrolled two hundred and twenty (220) subjects who underwent cataract surgery in one eye (unilateral). Subjects were assigned randomly (1:1) to receive either PROLENSA once daily or placebo (vehicle) once daily. Dosing of PROLENSA began one day before cataract surgery and continued on the day of surgery and for 14 days following cataract surgery. The proportion of subjects experiencing no ocular pain was assessed at Day 1 post surgery and throughout the study, and the proportion of subjects with complete absence of ocular inflammation was assessed as early as Day 1 post surgery through Day 22 post surgery. Ocular inflammation was evaluated using a summed ocular inflammation score (SOIS) and was measured by an assessment of cells in the anterior chamber of the eye ("cells") and cellular protein ("flare"). The secondary efficacy endpoint was evaluated via a pain score from the Ocular Comfort Grading Assessment (OCGA) recorded in a patient's diary. Safety was assessed based on several variables, including adverse events, ophthalmic evaluations, and OCGA.

ABOUT PROLENSA™
PROLENSA™ (bromfenac ophthalmic solution) is being developed as a once-daily topical nonsteroidal anti-inflammatory compound for the treatment of ocular inflammation and pain following cataract surgery. PROLENSA incorporates a lower concentration of bromfenac than the company's current once-daily NSAID, BROMDAY (bromfenac ophthalmic solution) 0.09% in a new, modified ophthalmic formulation. From 2005 until 2011, ISTA marketed XIBROM (bromfenac ophthalmic solution)® 0.09% in the U.S. for twice-daily use for the treatment of postoperative inflammation and the reduction of ocular pain in patients who have undergone cataract surgery. In October of 2010, ISTA received FDA approval for once-daily BROMDAY and discontinued shipments of XIBROM in February 2011. BROMDAY is currently the only once-daily treatment option in the $370 million U.S. ophthalmic nonsteroidal anti-inflammatory market. ISTA acquired the U.S. ophthalmic rights to bromfenac in May 2002 under a license from Senju Pharmaceuticals Co. Ltd. A U.S. patent was issued to ISTA's licensor, Senju, for PROLENSA, which expires in September 2025. PROLENSA is an investigational drug and not yet available for commercial use.
