A randomized, double-blind, multicenter Phase II study comparing the efficacy and safety of oral nemonoxacin with oral levofloxacin in the treatment of community-acquired pneumonia
Abstract
BACKGROUND/PURPOSE
To compare the clinical efficacy and safety of nemonoxacin with levofloxacin in treating community-acquired pneumonia (CAP) in a Phase II clinical trial.
METHODS
One hundred ninety-two patients with CAP were randomized to receive oral nemonoxacin (500 mg or 750 mg) or levofloxacin (500 mg) once daily for 7-10 days. Clinical and bacteriological responses were determined at the test of cure (TOC) visit in the full analysis set (FAS).
RESULTS
The clinical cure rate of nemonoxacin (500 mg), nemonoxacin (750 mg), and levofloxacin (500 mg) was 93.3%, 87.3%, and 88.5%, respectively, in the FAS (n = 168), and 93.0%, 93.9%, and 88.9%, respectively in the per protocol set (n = 152). At the TOC visit, nemonoxacin at 500 mg and 750 mg was proven to be noninferior to levofloxacin at 500 mg in the FAS in terms of clinical efficacy. The overall bacteriological success rate was 83.3% in both nemonoxacin groups and 80.0% in the levofloxacin 500 mg group in the bacteriological FAS. The comprehensive efficacy rate was comparable among the three groups (87.5% for the nemonoxacin 500 mg group, 93.8% for the nemonoxacin 750 mg group, and 81.3% for the levofloxacin 500 mg group). Most drug-related adverse events were mild and transient, mainly gastrointestinal symptoms such as nausea and vomiting, transient neutropenia, and elevated liver enzymes. No drug-related serious adverse events occurred.
CONCLUSION
Either 500 mg or 750 mg of oral nemonoxacin taken once daily for 7-10…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 168 participants or records.
