Primary Outcome Measures:

The primary endpoint will be the clinical response in the clinically evaluable (CE) population at the test-of-cure (TOC) visit. [ Time Frame: Clinical response rate (cure/failure rate) 10 to 28 days after the last dose of study antibiotic(s). ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To compare the microbiologic efficacy of tigecycline with that of the comparator in the microbiologically evaluable(ME)population [ Time Frame: Clinical response rate (cure/failure rate) 10 to 28 days after the last dose of study antibiotic(s). ] [ Designated as safety issue: No ]
To evaluate in vitro susceptibility data on tigecycline for a range of pathogenic bacteria that cause cSSSI [ Time Frame: Clinical response rate (cure/failure rate) 10 to 28 days after the last dose of study antibiotic(s). ] [ Designated as safety issue: No ]
To compare health care utilization between the treatment groups. [ Time Frame: Clinical response rate (cure/failure rate) 10 to 28 days after the last dose of study antibiotic(s). ] [ Designated as safety issue: No ]

Arms	Assigned Interventions
1: Active Comparator Arm 1: Tigecycline	Drug: Tigecycline Treatment A: Tigecycline every 12 hours IV (an initial dose of 100 mg followed by 50 mg every 12 hours)
2: Active Comparator Arm 2: Ampicillin-Sulbactam or Amoxicillin-Clavulanate plus or minus a glycopeptide	Drug: ampicillin-sulbactam Ampiciliin-sulbactam: 1.5 g (1 g amplicillin plus 0.5 g sulbactam) to 3 g (3 g ampicillin plus 1 g sulbactam) IV every 6 hrs or Amoxicillin-clavulnate: 1.2 g (1000 mg amoxicillin plus 200 mg clavulanate) IV every 6 to 8 hrs. A glycopeptide antibiotic (either vancomycin 1 g IV every 12 hrs or teicoplanin IV loading dose of 400 mg the first day followed by a maintainance dose of 200 mg daily) may be added to the aminopenicillin/betalactamase inhibitor regimen if infection with MRSA is suspected or confirmed within the first 72 hrs of enrollment. If culture results fail to show a resistant organism, use of the glucopeptide may be discontinued.
