Inclusion criteria

* Male and female subjects with signs or symptoms consistent with infection, and if available, laboratory findings consistent with staphylococcal infection (e.g., Gram stain and culture results). * Signs and symptoms consistent with infection * Infection suspected to be due to Methicillin Resistant Staphylococcus Aureus

Exclusion criteria

* Subjects who were treated with a previous antibiotic (systemic or topical) with MRSA activity (other than linezolid or vancomycin) for more than 24 hours and treatment extended into the 72 hour period prior to the first dose of study drug, unless documented to be a treatment failure (72 hours of treatment and not responding). * Subjects with uncomplicated skin or superficial skin structure infection such as superficial/simple cellulitis, impetiginous lesion, furuncle, or simple abscess that only need surgical drainage for cure. * Subjects excluded with necrotizing fasciitis, gas gangrene, osteomyelitis

Design outcomes

MeasureTime frameDescription
Clinical Outcome in Participants With Baseline Methicillin-Resistant Staphylococcus Aureus (MRSA) at End of Study (EOS) for Per-Protocol (PP) PopulationEOS (6 to 28 days after the last dose of study drug)Clinical response (CR) was based primarily on global assessment of clinical presentation of participant made by investigator at evaluation time point. At EOS, CR was evaluated as success (cure: resolution of clinical signs or (/) symptoms of infection when compared to baseline); failure: persistence/progression of baseline signs/symptoms of infection after at least 2 days of treatment/development of new clinical findings consistent with active infection; unknown: extenuating circumstances precluding classification to 1 of above.

Number of Participants With Clinical Signs and Symptoms at EOT and 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 of an active skin or soft tissue infection caused by suspected MRSA included purulent discharge, nonpurulent discharge, erythema, swelling, induration, tenderness, pain and local skin warmth. It was recorded by the sponsor using wound parameter score ranging from 0 to 3; 0= none, 1= mild, 2= moderate and 3= severe.

Time frame: EOT (within 72 hours of last dose of study drug), EOS (6 to 28 days after the last dose of study drug)

Population: PP set:who received at least 1 dose of drug, with appropriate diagnosis,MRSA as pathogen, satisfied all key inclusion/exclusion criteria, adequate dosing(failure:2 full days of drug, success:4 full days),observed outcome at EOS visit unless declared failure prior to the visit.Here,'n'=participants evaluable for specific clinical signs and symptoms.
