Abstract

Background and Objective: Besifloxacin ophthalmic suspension 0.6% given thrice daily for 5 days is safe and effective in the treatment of patients with bacterial conjunctivitis. This study evaluated the safety and efficacy of besifloxacin ophthalmic suspension 0.6% administered twice daily for 3 days compared with vehicle in the treatment of bacterial conjunctivitis.
Study Design: This was a multicenter, double-masked, randomized, vehicle-controlled, parallel-group study.
Methods: A total of 474 patients aged ≥1 year with bacterial conjunctivitis were randomized in a 1 : 1 ratio to receive either besifloxacin ophthalmic suspension 0.6% or vehicle administered twice daily for 3 days. There were three study visits: day 1 (the baseline visit), day 4/5 (visit 2), and day 7±1 (visit 3). The co-primary efficacy endpoints were bacterial eradication and clinical resolution at day 4/5 in designated study eyes of patients with culture-confirmed bacterial conjunctivitis. Secondary efficacy endpoints were bacterial eradication and clinical resolution at day 7±1, individual clinical outcomes of ocular discharge and bulbar conjunctival injection at all visits; and microbial and clinical outcomes for overall bacterial species and individual Gram- positive and Gram-negative bacterial species at each follow-up visit. Safety endpoints included adverse events (AEs), changes in visual acuity and biomicroscopy findings at each visit, and changes in ophthalmoscopy findings at day 7±1.
Results: Bacterial eradication and clinical resolution rates were significantly higher in the besifloxacin group than in the vehicle group (115/135 [85.2%] vs 77/141 [54.6%], p<0.001, and 89/135 [65.9%] vs 62/141 [44.0%], p<0.001, respectively) at day 4/5. Rates of bacterial eradication continued to be significantly greater in the besifloxacin group (115/135 [85.2%] vs 91/141 [64.5%], respectively; p<0.001) at day 7±1; however, the rates of clinical resolution did not differ significantly between the groups (103/135 [76.3%] and 94/141 [66.7%], p =0.209) at this visit. Ocular discharge and bulbar conjunctival injection at each visit were consistent with the primary outcomes. Clinical resolution and bacterial eradication with Gram-positive or Gram-negative organisms were consistent with the overall findings. All AEs in both groups were of mild or moderate severity and were considered unrelated to the treatment.
Conclusion: Treatment with besifloxacin ophthalmic suspension 0.6% administered twice daily for 3 days was effective and safe in adults and children with bacterial conjunctivitis.
