Primary Outcome Measures:
  • Number of Participants With a Clinical Response of Cure [ Time Frame: Test of Cure (TOC), day 10-20 ]
    To qualify as a Cure, participants were required to fulfill the following criteria: all systemic signs and symptoms of uSSSI present at screening were improved or resolved; no further antibiotic therapy was necessary for treatment of uSSSI; and there was no worsening or appearance of new signs and symptoms of uSSSI.

Secondary Outcome Measures:
  • Number of Patients With Per-Patient Microbiologic Response of Eradicated [ Time Frame: Test of Cure (TOC), day 10-20 ]
    The microbiological response at the patient level was considered Eradicated (documented or presumed)if no pathogens were present in repeat cultures taken from the original site of infection or a clinical response of cure precluded the ability to obtain a culturable specimen.

Also excluded are skin infections resulting from animal bites
  • Patients with a complicated skin and skin structure infection as judged by the Investigator
  • Infections that can be treated by surgical incision alone according to the judgment of the Investigator
  • Treatment with the following anti-infective agents prior to study drug administration: systemic antibiotic within 7 days; azithromycin within 14 days; a long-acting injectable antibiotic within 30 days
  • Any infection which requires the use of a concomitant antimicrobial agent, in addition to study drug
  • Concomitant topical therapy at the infection site for the period within 48 hours prior to study drug administration through TOC
  • A chronic or underlying skin condition at the site of infection or infections involving prosthetic materials
  • A wound secondary to burn injury or acne vulgaris
