title: A randomized double-masked study to compare the ocular safety, tolerability, and efficacy of bromfenac 0.075% compared with vehicle in cataract surgery subjects.
abstract: OBJECTIVE
  The aim of this study was to evaluate the safety, tolerability, and efficacy of a low-dose version of bromfenac 0.075% in DuraSite®(bromfenac 0.075%) compared with DuraSite®vehicle (vehicle) alone for the treatment of postoperative inflammation and ocular pain after cataract surgery.
  
  
  METHODS
  A multicenter, double-masked, vehicle-controlled, parallel-group clinical trial of 240 subjects randomized in a 2:1 ratio to bromfenac 0.075% or vehicle was conducted. Subjects were dosed BID beginning 1 day before the cataract surgery, the day of surgery, and 14 days after surgery. A slit lamp biomicroscopy examination was performed to evaluate the signs of inflammation, including anterior chamber cells (ACC) and anterior chamber flare (ACF). The primary efficacy variable was the proportion of subjects with an ACC grade of 0 at Day 15. Secondary efficacy endpoints included the proportion of subjects who achieved a pain score of 0 at each postsurgical visual analog scale (VAS) assessment and the proportion of subjects with an ACF grade of 0 at Day 15.
  
  
  RESULTS
  At Day 15, proportionally more subjects in the bromfenac 0.075% group than in the vehicle group had an ACC grade of 0 (57.1% vs 18.8%, respectively;P<0.001). At each of the postsurgical time points (Days 1, 8, 15, and 29), proportionally more bromfenac 0.075%-treated subjects (76.8%, 90.5%, 92.9%, and 85.1%, respectively) had no pain (a VAS score of 0) compared with the vehicle-treated subjects (48.2%, 38.8%, 42.4%, and 47.1%, respectively), and at each time point, these differences in proportions were statistically significant (P<0.001). More subjects in the bromfenac 0.075% group had complete ACF resolution (151/167; 90.4%) compared to those in the vehicle group (54/85; 63.5%). There were no new safety signals reported.
  
  
  CONCLUSIONS
  Bromfenac 0.075% in DuraSite is safe, well tolerated, and effective at reducing inflammation and preventing pain associated with cataract surgery.
