ISTA Pharmaceuticals issued a statement reporting a subpoena received from the US Attorney’s Office in Buffalo, “requesting the production of documents regarding promotional, educational and other activities relating to Xibrom (bromfenac sodium ophthalmic solution) 0.09%.”  
Xibrom is an ophthalmic solution indicated for the treatment of inflammation and ocular pain following cateract surgery.  Representatives of ISTA Pharmaceuticals were not immediately available for comment.
ISTA Pharmaceuticals previously reported clinical trial data showing “no statistically significant difference” between Xibrom and a new product, Xibrom QD.  Xibrom QD, to be taken once-per-day, would potentially replace Xibrom, taken twice-per-day.
