Randomized double-blind study comparing 7- and 10-day regimens of faropenem medoxomil with a 10-day cefuroxime axetil regimen for treatment of acute bacterial sinusitis

Abstract

Objective: To compare the efficacy and safety of faropenem medoxomil, 300 mg twice daily for seven or ten days, with cefuroxime axetil 250 mg twice daily for ten days in adults with acute bacterial sinusitis (ABS).

Study design and setting: Prospective, double-blinded, phase III trial with entry criteria consistent with FDA/IDSA guidelines for diagnosis of ABS. Primary efficacy parameter was clinical response at 7 to 21 days posttherapy.

Results: One thousand ninety-nine subjects were randomized and treated; 861 were efficacy valid. Clinical cure rates were 80.3% for seven days of faropenem, 81.8% for ten days of faropenem, and 74.5% for 10 days of cefuroxime axetil. The incidence of adverse events and premature discontinuations were similar for the three treatment regimens.

Conclusions: Seven- and ten-day faropenem medoxomil regimens were similar (noninferior) to a ten-day cefuroxime axetil regimen based on clinical response in patients with ABS.

Significance: A seven-day course of faropenem medoxomil 300 mg twice-daily regimen is a promising alternative for treatment of ABS.
