ABSTRACT

OBJECTIVES: To evaluate the efficacy and safety of oral sitafloxacin versus oral moxifloxacin in the treatment of Chinese adults with community-acquired pneumonia (CAP).

PATIENTS AND METHODS: This is a multicenter, randomized, open-label, positive-controlled clinical trial (chinadrugtrials.org.cn identifier: CTR20130046). CAP patients received sitafloxacin tablets 100 mg once daily (qd) or 100 mg twice daily (bid) to compare with moxifloxacin tablets 400 mg qd, for 7-10 days. The primary outcome was non-inferiority of sitafloxacin to moxifloxacin in clinical cure rate at test of cure (TOC) visit in per-protocol set (PPS).

RESULTS: A total of 343 patients were randomized (sitafloxacin 100 mg qd, n = 117; sitafloxacin 100 mg bid, n = 116; moxifloxacin, n = 110), 291 patients were included in the PPS (sitafloxacin 100 mg qd, n = 96; sitafloxacin 100 mg bid, n = 94; moxifloxacin, n = 101). The clinical cure rate was 94.8% in the sitafloxacin 100 mg qd group, 96.8% in the sitafloxacin 100 mg bid group and 95.0% in the moxifloxacin group. At the TOC visit, the microbiological success rate was 97.0% (32/33) in the sitafloxacin 100 mg qd group, 97.1% (34/35) in the sitafloxacin 100 mg bid group and 94.9% (37/39) in the moxifloxacin group in the microbiological evaluable set (MES). The incidence of study-drug-related adverse events (AEs) was 23.3% (27/116) in the sitafloxacin 100 mg qd group, 29.8% (34/114) in the sitafloxacin 100 mg bid group and 28.2% (31/110) in the moxifloxacin group (p > .05). The common AEs related to study drug were dizziness, nausea, diarrhea, increased platelet count and alanine transaminase (ALT) elevation. All the AEs resolved completely after discontinuation of study drug.

CONCLUSION: Sitafloxacin 100 mg qd or 100 mg bid for 7-10 days is not inferior to moxifloxacin 400 mg qd for 7-10 days in clinical efficacy for adult CAP patients. Sitafloxacin provides a safety profile comparable to moxifloxacin.
