A Phase III Study to Evaluate the Safety, Efficacy and Pharmacokinetics/Pharmacodynamics of BAYQ3939 in Patients With Bacterial Pneumonia

The main objective of this study is to investigate the safety, pharmacokinetics (PK) and the relationship between PK and pharmacodynamics (Minimum Inhibitory Concentration [MIC] and Mutant Prevention Concentration [MPC]) of intravenous BAYQ3939 (400 mg BID and 400 mg TID) in hospitalized patients with bacterial pneumonia or secondary infection of chronic respiratory disease with severe disease or a poor response to other antimicrobials. In addition, the efficacy of the ciprofloxacin, in terms of clinical response and microbiological response, will be investigated, but as a secondary endpoint.
