Methicillin Resistant Staphylococcus Aureus (MRSA)

Keywords

Staphylococcal pneumonia, Methicillin-resistant staphylococcal pneumonia, healthcare-associated pneumonia

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.

DRUGvancomycin

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.

Survival Status Estimated by Kaplan-Meier Analysis for PP PopulationFrom 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.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.

Outcome results

Clinical Outcome in Participants With Baseline Methicillin Resistant Staphylococcus Aureus (MRSA) at End of Study (EOS) for PP Population

Clinical response was based primarily on global assessment of clinical presentation of participant made by investigator at evaluation timepoint. Clinical response was evaluated at EOS Visit as Cure: resolution of clinical signs/symptoms of pneumonia when compared with baseline; Failure: persistence/progression of baseline signs/symptoms of pneumonia or baseline radiographic abnormalities after atleast 2 days of treatment; development of new pulmonary/extrapulmonary clinical findings consistent with active infection; Unknown:extenuating circumstances precluding classification to 1 of the above.

Time frame: EOS (7-30 days after last dose)

Population: PP population included all mITT participants who satisfied all critical inclusion/exclusion criteria,had adequate dosing of drug (defined as 5 full days for success or 2 full days of treatment for participants whose clinical outcome was considered failure) and had observed outcome for that visit unless already declared failure prior to that visit.

Number of Participants With Clinical Signs and Symptoms at EOS for PP 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: PP population included all mITT participants who satisfied all critical inclusion/exclusion criteria,had adequate dosing of drug (defined as 5 full days for success or 2 full days of treatment for participants whose clinical outcome was considered failure)and had observed outcome for that visit unless already declared 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.
