Primary Outcome Measures:
  • clinical response at the test of cure visit [ Time Frame: 7-14 days after end of treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • clinical response at end of treatment and follow-up visit; [ Time Frame: end of treatment and at follow up ] [ Designated as safety issue: No ]
  • microbiological response at test of cure visit [ Time Frame: end of treatment ] [ Designated as safety issue: No ]
  • change in Community acquired pneumonia symptom questionnaire. [ Time Frame: end of treatment and follow up ] [ Designated as safety issue: No ]
  • Safety and tolerability will be measured by adverse event (AE) reporting including mortality, vital signs, physical examinations and safety laboratory results [ Time Frame: screening-follow up ] [ Designated as safety issue: Yes ]
  • Population pharmacokinetics [ Time Frame: Inpatient and day of IV to oral switch ] [ Designated as safety issue: No ]
  • healthcare resource utilization [ Time Frame: screening, test if cure and follow-up ] [ Designated as safety issue: No ]
