OBJECTIVE: To compare the efficacy and safety of ciprofloxacin otic solution 0.2% to polymyxin B-neomycin-hydrocortisone (PNH) otic solution in the treatment of acute diffuse otitis externa in children, adolescents, and adults. METHODS: This was a randomized, parallel-group, evaluator-blind, active-controlled, multicenter, noninferiority study. The primary efficacy endpoint was clinical cure of otitis symptoms at the test-of-cure (TOC) visit. Clinical cure at the end-of-treatment (EOT) visit and percentages of patients with clinical improvement and resolution and/or improvement of otalgia at EOT and TOC visits were secondary efficacy endpoints. RESULTS: A total of 630 patients were randomized to ciprofloxacintwice daily (n = 318) or PNH 3 times daily (n = 312) for 7 days. Ciprofloxacin was shown to be noninferior to PNH. The percentage of patients with clinical cure at the TOC visit was 86.6% with ciprofloxacin and 81.1% with PNH; the treatment difference was 5.6% in favor of ciprofloxacin (95% CI: -0.9 to 12.1). At the EOT visit, clinical cure was achieved in 70.0% and 60.5% of patients, respectively, with a treatment difference in favor of ciprofloxacin (9.5%, 95 CI: 1.2 to 17.9). In all secondary efficacy variables, ciprofloxacin and PNH showed similar results, including pain duration and resolution. The clinical cure rate for patients with baseline cultures showing P. aeruginosa was 87.5% in the ciprofloxacin group and 78.6% in the PNH group, a treatment difference of 8.9% in favor of ciprofloxacin (95% CI: 0.6 to 17.3); for patients with baseline cultures showing S. aureus, the clinical cure rate was 72.7% for the ciprofloxacin group and 75.9% for the PNH group (treatment difference of 3.1% in favor of PNH, 95% CI: -21.1% to 27.4%). Most adverse events were mild and unrelated to study medication in both treatment groups. A limitation of this study is the assessment of signs and symptoms at baseline and after treatment, which does not provide data to evaluate the interim response. CONCLUSIONS:Ciprofloxacin otic solution 0.2% was found to be noninferior to PNH. This efficacy, good tolerability, and ease of administration make ciprofloxacin otic solution 0.2% without a topical steroid an attractive option for the treatment of acute otitis externa.

Clinical cure at the end-of-treatment (EOT) visit and percentages of patients with clinical improvement and resolution and/or improvement of otalgia at EOT and TOC visits were secondary efficacy endpoints. RESULTS: A total of 630 patients were randomized to ciprofloxacin twice daily (n = 318) or PNH 3 times daily (n = 312) for 7 days. Ciprofloxacin was shown to be noninferior to PNH. The percentage of patients with clinical cure at the TOC visit was 86.6% with ciprofloxacin and 81.1% with PNH; the treatment difference was 5.6% in favor of ciprofloxacin (95% CI: -0.9 to 12.1).
