Title: A Phase 3, Multicenter, Randomized, Double-blind, Comparative Study to Evaluate the Safety and Efficacy of Ceftaroline Versus Vancomycin Plus Aztreonam in Adult Subjects With Complicated Skin and Skin Structure Infection (cSSSI)
Brief Summary: The purpose of this study is to determine whether ceftaroline is effective and safe in the treatment of complicated skin infections in adults.


Options:
A: Inclusion Criteria:

* Skin and skin structure infection (SSSI) that involves deeper soft tissue or requires significant surgical intervention, or cellulitis or abscess on lower extremity which occurs in subjects with diabetes mellitus or well-documented peripheral vascular disease.

Exclusion Criteria:

* Prior treatment of current complicated skin and skin structure infection (cSSSI) with an antimicrobial.
* Failure of vancomycin or aztreonam as therapy for the current cSSSI, or prior isolation of an organism with in vitro resistance to vancomycin or aztreonam.
B: Inclusion Criteria:

* Diagnosis of acute bacterial skin-structure infection (ABSSI) of no more than 7 days duration which was suspected or proven to be caused, at least in part, by a gram-positive pathogen.
* Eligible infections included cellulitis measuring at least 10 cm length and width or 100 cm squared, with or without a focal abscess, and surgical or traumatic wound infections
* Infection which in the opinion of the investigator will require 10-14 days of antibacterial therapy.
* Have at least 3 of the following local and/or systemic symptoms and/or signs of infection: purulent or seropurulent drainage/discharge, erythema, fluctuance, heat/localized warmth, pain/tenderness to palpation, swelling/induration, regional lymph node swelling or tenderness, temperature \>=100.4 degree F, increased white blood cell count, or bandemia.
* Must not have received treatment with another systemic antibiotic for the current ABSSI.

Exclusion Criteria:

* Superficial skin structure infections such as folliculitis, carbuncles, furunculosis, cutaneous abscesses, and simple cellulitis.
* Infections involving burns, human or animal bites, or chronic diabetic foot ulcers.
* Suspected polymicrobial infection involving Pseudomonas aeruginosa
* Anticipated need for \>14 days of antibiotic therapy.
* Infections complicated by the presence of prosthetic materials that will not be removed, such as permanent cardiac pacemaker battery packs, mesh, or joint replacement prosthesis.
* Known significant renal, hepatic, or hematologic impairment.
* Received prior potentially effective antimicrobial therapy for the acute bacterial skin and skin structure infection, unless they were failing therapy after 48 hours or had a gram-positive pathogen non-susceptible to prior therapy identified as a causative pathogen.
C: Inclusion Criteria:

* Skin and skin structure infection (SSSI) that involves deeper soft tissue or requires significant surgical intervention, or cellulitis or abscess on lower extremity which occurs in subjects with diabetes mellitus or well-documented peripheral vascular disease.

Exclusion Criteria:

* Prior treatment of current cSSSI with an antimicrobial.
* Failure of vancomycin or aztreonam as therapy for the current cSSSI, or prior isolation of an organism with in vitro resistance to vancomycin or aztreonam.
D: Inclusion Criteria:

* Type 1 or 2 Diabetes Mellitus treated with diet or medication
* Clinically or microbiologically documented foot infection below the knee
* Osteomyelitic bone must be removed within 48 hours of study entry

Exclusion Criteria:

* Uncomplicated skin infections
* Infected burn wounds
* Necrotizing fascitis
* Wounds with gangrene that cannot be removed with debridement
* Infections of prosthetic materials
* Foreign materials that can not be removed by surgical debridement
* Patients with another antibiotic 3 days prior to enrollment without evidence of treatment failure and presence of a positive culture
* Insufficient blood flow to the limb requiring a revascularization procedure
