Study Endpoints
Primary Endpoints
Efficacy Adjudication Committee (EAC) Assessment of Number of Participants With Clinical Success at Test of Cure (TOC)
7-14 days for SSTI, 14-42 days for septicemia and right-sided infective endocarditis (RIE)

Clinical Success = Study investigator's Clinical Response confirmed by the EAC as either cured or improved at end of treatment (EOT). MITT-MRSA (modified intent-to-treat - methicillin-resistant Staphylococcus aureus) was a subset of allocated participants with participants who were excluded for any of the following reasons: no MRSA isolated + any 1 of the following: failure to receive ≥1 dose of study drug, lack of all post-allocation primary and secondary endpoint data after ≥1 dose of study drug, no gram (+) coccus isolated at baseline.

Efficacy Adjudication Committee (EAC) Assessment of Number of Participants With Microbiological Response at TOC
7-14 days for SSTI, 14-42 days for septicemia and RIE

Response = eradicated or presumed eradicated. Eradicated was defined as absence of the admission pathogen in a culture obtained in the absence of potentially effective antibiotics for the pathogen. Presumed eradicated was defined as no material for culture was available due to improvement of infection, but the admission pathogen was presumed to be eradicated because the participant was deemed "Cured" or "Improved" by the investigator and the participant did not receive potentially effective antibiotics for the pathogen.
