The purpose of this study is to Evaluate the Efficacy, safety and pharmacokinetics of Intravenous Nemonoxacin Compared with Intravenous Moxifloxacin in Adult Patients with community-acquired pneumonia (CAP).
Community-acquired Pneumonia (CAP) remains a leading cause of death in both developing and developed countries. In the choice of antibacterial agents used to treat CAP, fluoroquinolones have received considerable attention because of their wide spectrum of bactericidal activity. TG-873870 (Nemonoxacin), a non-fluorinated quinolone (NFQ), is a selective bacterial topoisomerase inhibitor.

This study will Evaluate the clinical efficacy, microbiological efficacy and safety of Intravenous Nemonoxacin compared with Intravenous Moxifloxacin in adult patients with community-acquired pneumonia.

Besides, the pharmacokinetics (PK) of Nemonoxacin in adult patients with CAP after continuous IV Infusion and the pharmacokinetic (PK)/pharmacodynamic (PD)are to be determined.

Difference in the Clinical Cure Rate of Two Doses of Intravenously Infused Nemonoxacin Malate Sodium Chloride Injection at Visit 4 in the mITT Population

The primary efficacy endpoint of this study was to evaluate whether the clinical cure rate of Nemonoxacin malate sodium chloride is non-inferior to that of Moxifloxacin at visit 4 in the mITT population. At visit 4, the Investigator would assess changes in the symptoms/signs/laboratory tests and chest X-rays/or CT scans associated with this infection, and determined the clinical efficacy in the subjects. The clinical efficacy of the study group and the control group was calculated according to the proportion and percentage of overall clinically cured and clinically ineffective patients in the treatment groups. If the lower limit of the 90% confidence interval for the difference in the clinical cure rate between the study drug and the control drug was larger than -15%, it would be established that the efficacy of Nemonoxacin malate sodium chloride injection was not inferior to that of Moxifloxacin Hydrochloride Sodium Chloride Injection in the treatment of moderate to severe adult CAP.

Subject Number for Microbiologically Cured and Failure at Visit 4 in b-mITT (Bacteriological mITT) Population

Microbiological efficacy at visits 4 would be determined by assessing the identification results from the central laboratory. Subjects must satisfy at least one of the following in order to be evaluated for the microbiological efficacy: Subjects whose respiratory culture from visit 1 was positive; Subjects whose blood culture from visit 1 was positive. The microbiological efficacy at Visit 4 and treatment group (determined by each subject) was determined by the number and percentage of microbiological success subjects. The difference in bacteriological success between Nemonoxacin malate sodium chloride injection and Moxifloxacin Hydrochloride Sodium Chloride Injection was tested using the logistic regression model.
