ISTA Pharmaceuticals Highlights Bepreve(TM) Clinical Data at the 2009 Annual Meeting of the American College of Allergy, Asthma & Immunolo...( MIAMI Nov. 9 /- ISTA Pharmaceuticals ...),Health

MIAMI, Nov. 9 /PRNewswire-FirstCall/ -- ISTA Pharmaceuticals, Inc. (Nasdaq: ISTA), today announced additional results from the Company's Bepreve(TM) (bepotastine besilate ophthalmic solution) 1.5% Phase 3 clinical studies. These results were presented in poster sessions at the 2009 Annual Meeting of the American College of Allergy, Asthma & Immunology (ACAAI) in Miami Beach, FL.

In a poster presentation titled, "Treatment of Ocular Itching with Bepotastine Besilate Ophthalmic Solution 1.5% for Subjects with More Severe Itching Response in a Conjunctival Allergen Challenge (CAC) Clinical Model of Allergic Conjunctivitis," integrated results from two Phase 3 studies demonstrated Bepreve 1.5% was as effective in suppressing ocular itching in patients with more severe itching as in patients with all grades of ocular itching. A total of 157 patients were enrolled in two 7-week, masked, randomized, placebo-controlled CAC clinical studies (1 single site, 1 multi-site). 113 patients exhibited bilateral ocular itching grades greater than or equal to 3 at screening during study visit 2. Individuals were assessed at 15 minutes, 8 hours, or 16 hours following instillation at study visits spaced 2 weeks apart during the enrollment period. The difference in mean itching grades (placebo-active) for the more severely affected subjects was within plus or minus 0.1 unit of the differences for the entire intent-to-treat (ITT) population. Authors of the poster were J. I. Williams, J. A. Gow, P. J. Gomes, M. B. Abelson, and T. R. McNamara.

ISTA presented more results from CAC clinical trials with Bepreve 1.0% and 1.5% in the following poster presentations at the same meeting:
