  • OBJECTIVE: This study aimed to compare the efficacy and safety of oral gemifloxacin, an enhanced-affinity quinolone, with sequential therapy with IV ceftriaxone followed by oral cefuroxime (with or without a macrolide) in patients hospitalized for community-acquired pneumonia (CAP). METHODS: A randomized, open-label, multicenter study comprised adults hospitalized with a clinical and radiologic diagnosis of CAP. Patients were randomized 1:1 to receive either (1) oral gemifloxacin 320 mg once daily (7-14 days); or (2) IV ceftriaxone 2 g once daily (1-7 days) followed by oral cefuroxime 500 mg twice daily (1-13 days) for a total of < or = 14 days. Patients receiving ceftriaxone/cefuroxime were allowed concomitant macrolide treatment. RESULTS: A total of 345 patients were randomized, of whom 341 received at least 1 dose of study medication (gemifloxacin, 169/172; ceftriaxone/cefuroxime, 172/173). Clinical success rates in the clinically evaluable (CE) population at follow-up (day 21-28 post-therapy), the primary end point, were 92.2% (107/116) for gemifloxacin and 93.4% (113/121) for ceftriaxone/cefuroxime (treatment difference, -1.15; 95% CI, -7.73 to 5.43). In patients in Fine risk classes IV and V, the clinical success rate was 87.0% (20/23) for gemifloxacin versus 83.3% (20/24) for ceftriaxone/cefuroxime. No difference in clinical response at follow-up was noted based on macrolide use. Bacteriologic success rates at follow-up in the bacteriologically evaluable (BE) population were 90.6% (58/64) for gemifloxacin and 87.3% (55/63) for ceftriaxone/cefuroxime (treatment difference 3.32; 95% CI, -7.57 to 14.21). The clinical success rate in bacteremic patients at follow-up (BE population) was 100.0%. Both treatments were generally well tolerated. The frequency and types of adverse events were similar between the 2 groups. The most common treatment-related adverse events with gemifloxacin were diarrhea, liver-function adverse events, and rash; with ceftriaxone/cefuroxime, they were diarrhea, elevated hepatic-enzyme activity, and moniliasis. CONCLUSION: The clinical efficacy and tolerability of oral gemifloxacin 320 mg once daily were similar to those of IV ceftriaxone followed by oral cefuroxime (with or without a macrolide) in the treatment of adult patients hospitalized with moderate to severe CAP. Both treatments were effective in bacteremic patients and those at increased risk of mortality.
