Brief summary
To determine if linezolid is superior to vancomycin in the treatment of nosocomial (acquired in the hospital) pneumonia due to Methicillin Resistant Staphylococcus Aureus (MRSA) in adult subjects. Subjects entered in to the study will have proven healthcare-associated methicillin-resistant Staphylococcus aureus pneumonia which will be treated with either linezolid or vancomycin.
Interventions
Subjects to receive either linezolid 600 mg IV (Intravenous) or PO (orally) q 12 h (every 12 hours) for 7-14 days, except in cases of documented bacteremia where it could be extended to 21 days based upon investigator's discretion.
Subjects to receive vancomycin 15mg/kg IV (Intravenous) q12h (every 12 hours), adjusted for renal function, for 7-14 days, except in cases of documented bacteremia where it could be extended to 21 days based upon investigator's discretion.

Eligibility
Inclusion criteria
* Hospitalized male and female subjects with clinically documented nosocomial pneumonia proven to be due to methicillin-resistant staphylococcus aureus. * Chest X-ray at baseline/screen or within 48 hours of treatment consistent with the diagnosis of pneumonia. * Suitable sputum specimen defined as having less than 10 squamous epithelial cells and greater or equal 25 leukocytes or have a culture taken by an invasive technique within 24 hours of study entry.
Exclusion criteria
* Subjects who were treated with a previous antibiotic with MRSA activity (other than linezolid or vancomycin) for more than 48 hours, unless documented to be a treatment failure (72 hours of treatment and not responding). * Subjects with severe neutropenia (\<500 cells/mm3) * Subjects with hypersensitivity to oxazolidinones or vancomycin.

Number of Participants With Clinical Signs and Symptoms at EOS for mITT Population
Participant's clinical evaluation of signs and symptoms were based on global assessment by investigator at specific timepoints. Signs and symptoms (mild to severe) of nosocomial pneumonia included cough; production of purulent sputum or change in character of sputum;auscultatory findings on pulmonary examination of rales and/or pulmonary consolidation (dullness on percussion, bronchial breath sounds, or egophony); and dyspnea, tachypnea, or hypoxemia with PaO2 \<60 mmHg or worsening gas exchange or increased oxygen requirements; pleuritic chest pain; chills/rigors; and decreased breath sounds.
Time frame: EOS (7-30 days after last dose)
Population: mITT population included all ITT participants who received at least 1 dose of drug with a diagnosis of nosocomial pneumonia caused by proven MRSA and had an observed outcome for that visit unless already declared a failure prior to that visit.

Survival Status Estimated by Kaplan-Meier Analysis for ITT Population
For each participant, time to death was estimated from baseline to date of first documented progression or date of death from any cause, whichever came first, assessed up to 60 days after last dose. The distribution of survival was estimated for the treatment groups using the Kaplan-Meier, product-limit method and compared between the treatment groups using the log rank statistic.
Time frame: From baseline until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 60 days after last dose.
Population: ITT population included all participants who received at least one dose of study medication.
