What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Clinical Cure Rate at Test of Cure (TOC) (MITT Population)	Cure: Total resolution of all signs and symptoms of the baseline infection, or improvement of the infection such that no further antimicrobial therapy was necessary. Failure: Requirement of alternative antimicrobial therapy for primary infection of cSSSI due to inadequate response, recurrence, new infection at the same site; treatment-limiting adverse event (AE); requirement for surgery due to failure of study drug; diagnosis of osteomyelitis after Study Day 8; or death caused by cSSSI. Indeterminate: Inability to determine an outcome	8-15 days after the end of treatment
Clinical Cure Rate of Ceftaroline Compared With That of Vancomycin Plus Aztreonam Treatment at TOC in the Clinically Evaluable (CE) Population		8-15 days after last dose of study drug

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Microbiological Success Rate at the TOC Visit		8-15 days after last dose of study drug
Clinical Response at the End of Therapy (EOT) Visit		Last day of study drug administration
Clinical and Microbiological Response by Pathogen at the TOC Visit		8-15 days after last dose of study drug
Clinical Relapse at the Late Follow Up (LFU) Visit		21 to 35 days after the last dose of study drug
Microbiological Reinfection or Recurrence at the LFU Visit		21 to 35 days after the last dose of study drug
Assess Safety	Comparisons of the number of participants with Adverse Events	First dose of study drug through TOC visit
