- Early Clinical Response [ Time Frame: 96 (+/- 24) hours after the first dose of study drug ]Early clinical response defined as improvement in at least 2 of the following symptoms (as assessed by the investigator): chest pain, frequency or severity of cough, amount and quality of productive sputum, and difficulty breathing, and no worsening in the other symptoms in the ITT population.
- Early Clinical Response plus improvement in vital signs and no worsening of the 4 symptoms [ Time Frame: 96 (+/- 24) hours after the first dose of study drug ]Early clinical response with the addition of improvement in vital signs and no worsening of the following 4 symptoms: chest pain, cough, productive sputum, and difficulty breathing, required as Response in the ITT population
- Clinical Outcome at Test of Cure [ Time Frame: 5 to 10 days after the last dose of study drug ]Clinical outcome (Success, Failure, or Indeterminate/missing) based on the investigator's assessment of the patient's signs and symptoms of infection in the clinically evaluable and ITT populations.
- Clinical Outcome at End of Treatment [ Time Frame: Up to 24 (+4) hours after the last dose of study drug ]Clinical outcome (Success, Failure, or Indeterminate/missing) based on the investigator's assessment of the patient's signs and symptoms of infection in the clinically evaluable and ITT populations.
- Microbiologic Response [ Time Frame: 5 to 10 days after the last dose of study drug ]Microbiological response for subjects in the MITT and ME set will be based on results of the baseline and follow-up cultures and susceptibility testing or serology.
- All-cause Mortality [ Time Frame: Day 28 (+/- 2 days) ]All-cause Mortality
