A Phase III Study to Evaluate the Efficacy and Safety of Intravenous Infusion of Nemonoxacin in Treating CAP

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02205112
Recruitment Status : Completed
First Posted : July 31, 2014
Last Update Posted : November 27, 2017

Brief Summary:
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).

Condition or disease Intervention/treatment Phase
Community-acquired Pneumonia Drug: Nemonoxacin Drug: Levofloxacin Phase 3

Detailed Description:

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 levofloxacin in adult patients with community-acquired pneumonia.

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

Primary Outcome Measures :
  1. Per subject clinical cure rate [ Time Frame: end of treatment and 7 to 14 days after the end of treatment ]
    The clinical cure rate will be evaluated according to signs and symptoms and changes in the chest X-ray

Secondary Outcome Measures :
  1. Per subject microbiological cure rate [ Time Frame: end of treatment and 7 to 14 days after the end of treatment ]
    The microbiological cure rate will be evaluated according to the microbiological identification results of the central laboratory

  2. Per subject overall cure rate [ Time Frame: end of treatment and 7 to 14 days after the end of treatment ]
    Evaluate the overall efficacy after a comprehensive consideration of the clinical results and the bacteriological results.

  3. Safety evaluation [ Time Frame: duration of trial ]
    Incidence and severity of AE and changes in safety parameters from baseline
